Perfil de resistência antimicrobiana de Klebsiella pneumoniae isoladas de animais domésticos e silvestres / Antimicrobial resistance profile of Klebsiella pneumoniae isolated from domestic and wild animals

Klebsiella pneumoniae é um patógeno oportunista, responsável por diversos tipos de infecções nosocomiais, e é considerado um microrganismo multirresistente. Dados na literatura que forneçam informações a respeito da resistência desse microrganismo a antimicrobianos em amostras de animais são escassos. Dessa forma, o objetivo deste trabalho foi avaliar o perfil e o seu aumento das resistências a antimicrobianos dentro da medicina veterinária. Um total de 67 isolados de K. pneumoniae, provenientes de diferentes sítios de isolamento de animais domésticos (39/67) e silvestres (28/67), foi confirmado por sequenciamento do gene 16S rRNA. O maior percentual de isolamento de K. pneumoniae foi de amostras de urina, com 16% (11/67), fezes, com 15% (10/67), e pulmão, com 13,5% (09/67). No perfil de resistência, foram testadas 11 categorias de antibióticos, sendo a maior taxa de resistência ao metronidazol 97% (65/67), à ampicilina 94% (63/67), à amoxicilina 93% (62/67), às sulfonamidas 93% (62/67), à colistina 93% (62/67) e à nitrofurantoína 88% (59/67). Aqueles que apresentaram menor taxa de resistência foram: meropenem 3% (2/67), imipenem 6% (4/67) e amicacina 16% (11/67). Todos os isolados foram considerados bactérias multirresistentes (MRD), com o índice de resistência múltipla aos antibióticos (IRMA) variando de 0,15 a 0,85 e com 60 tipos de padrões de resistência. O resultado deste estudo reforça que os animais são reservatórios de K. pneumoniae multirresistentes.(AU)

Klebsiella pneumoniae is an opportunistic pathogen responsible for several types of nosocomial infections and is considered a multiresistant microorganism. Data in the literature that provide information regarding the resistance of this microorganism to antimicrobials in animal samples are scarce. Thus, the objective of this work was to evaluate the profile and its increase of antimicrobial resistance within Veterinary Medicine. A total of 67 K. pneumoniae isolates from different domestic (39/67) and wild (28/67) isolation sites were confirmed by sequencing the 16S rRNA gene. The highest percentage of K. pneumoniae isolation was from urine samples with 16% (11/67), faeces 15% (10/67) and lung 13.5% (09/67). In the resistance profile, 11 categories of antibiotics were tested, with the highest resistance to metronidazole being 97% (65/67), ampicillin 94% (63/67), amoxicillin 93% (62/67), sulfonamides 93% (62 / 67), 93% colistin (62/67), and 88% nitrofurantoin (59/67). The ones with the lowest resistance were: meropenem 3% (2/67), imipenem 6% (4/67) and amikacin 16% (11/67). All isolates were considered multiresistant bacteria (MDR), with the Multiple Resistance to Antibiotics Index (IRMA) ranging from 0.15 to 0.85 and with 60 types of resistance patterns. The result of this study reinforces that the animals are reservoirs of multiresistant K. pneumoniae.(AU)

Reservorios de leptospirosis en Camagüey: dos resultados y una misma base de datos / Leptospirosis reservoirs in Camagüey: two results and a same database

El objetivo del trabajo fue establecer la fiabilidad de las variables número de muestras y proporción de reactores positivos por especie para el estudio de los animales domésticos como reservorios de leptospirosis en Camagüey. Se hizo una base de datos con los reactores a Leptospira a partir de los sueros sanguíneos de 2 659 bovinos, 2 617 equinos, 814 porcinos, 75 ovinos-caprinos y 69 caninos de la provincia. Los resultados, atendiendo al número de muestras, dieron a bovinos (43 por ciento) y equinos (41 por ciento) como reactores hegemónicos; porcinos (13 por ciento), caninos (1 por ciento) y ovino-caprinos (1 por ciento) mostraron un comportamiento muy inferior. En función de la proporción de reactores por especie, bovinos, porcinos, caninos y caballares prevalecieron homogéneamente (P<0,05) a diferencia de ovino-caprino. Los caballos destinados a la transportación urbana constituyeron un riesgo potencial para el ser humano

The objective of the work was to establish the reliability of the variable number of samples and proportion of positive reactors by species for the study of the domestic animals as leptospirosis reservoirs in Camagüey. A database was made with the reactors to Leptospira from the sanguine serums of 2 659 bovine, 2 617 equine, 814 swinish, 75 ovines-caprines and 69 canines of the province. According to the number of samples, the results gave to bovine (43 percent) and equine (41 percen) as hegemonic reactors; swinish (13 percen), canine (1 percent) and ovine-caprines (1 percen) showed a very inferior behavior. In function of the proportion of reactors by species, bovine, swinish, canine and horses prevailed homogeneously (P<0,05) contrary to ovine-caprine. Horses dedicated to the urban transportation constituted a potential risk for the human being.

Gastroenteritis por Salmonella spp. en tres lactantes asociada a contacto con tortugas acuáticas / Salmonella spp. gastroenteritis associated to pet turtles in three infants

Non-typhoidal salmonellosis is an important cause of acute diarrhea in children. Generally they are acquired by consumption of contaminated food, but contact with reptiles is an increasing cause of this zoonoses. We describe three pediatric cases of gastroenteritis by Salmonella (Montevideo, Newport and Pomona), related to having turtles as pets. In two cases, the bacteria were isolated from the patient’s stools and the turtle’s droppings. The same genetic subtype by PFGE was obtained in both isolates. All the children recovered. Information and public health measures should be undertaken to control this zoonoses which affects young children.

Las infecciones por Salmonella no tíficas, son una importante causa de diarrea aguda en niños. Generalmente adquiridas por alimentos contaminados, el contacto con animales, especialmente reptiles, también es responsable de esta zoonosis. Describimos tres casos de lactantes con gastroenteritis por Salmonella (S. Montevideo, S. Newport y S. Pomona), relacionados a contacto con tortugas mascotas. En dos de los casos se aisló Salmonella en las deposiciones de los niños y de las tortugas. En todos hubo proximidad entre los niños y los acuarios y/o tortugas, siendo probable la contaminación en la preparación de alimentos. El estudio de clonalidad por electroforesis de campo pulsado demostró el mismo subtipo genético en el aislado correspondiente al paciente y en el procedente de la mascota, lo cual confirmó la fuente zoonótica de los casos. Esta zoonosis debe ser abordada por las autoridades de salud y las sociedades científicas, ya que representa un importante riesgo para la salud, especialmente de niños pequeños.

Evidence of Borrelia in wild and domestic mammals from the state of Minas Gerais, Brazil / Evidência de Borrelia em mamíferos silvestres e domésticos no Estado de Minas Gerais, Brasil

The main of the study was to evaluate the presence of Borrelia burgdorferi infection in domestic and wild vertebrates and ectoparasites in endemic areas from the state of Minas Gerais, Brazil. A total of 445 serum samples were examined by ELISA, which used the Borrelia burgdorferi strain G39/40 U.S. source and 3,821 tick samples were tested by polymerase chain reaction (PCR). B. burgdorferi antibodies were found in 30 serum samples (6.74%); three in marsupials (7.69%), three in rodents (2.80%), nine in dogs (6.25%), and 15 in horses (9.68%). Nested-PCR performed in DNA samples obtained from collected ticks demonstrated negative results. Although attempts to amplify B. burgdorferi DNA from ticks had been not successful, the presence of seroreactive vertebrates suggests the possibility the Borrelia species circulating in these regions. Further research is required to provide information on the presence of Borrelia in Brazilian territory and its association with Baggio-Yoshinari syndrome.

O principal objetivo do estudo foi avaliar a presença de infecção por Borrelia burgdorferi em vertebrados domésticos e silvestres e ectoparasitas em áreas endêmicas do estado de Minas Gerais, Brasil. Um total de 445 amostras de soro foram examinadas por ELISA, onde usou-se a cepa americana G39/40 de Borrelia burgdorferi e 3.821 amostras de carrapatos foram testados pela reação em cadeia da polimerase (PCR). Anticorpos anti -B. burgdorferi foram encontrados em 30 amostras de soro (6,74%); três marsupiais (7,69%), três em roedores (2,80%), em nove cães (6,25%) e 15 em cavalos (9,68%). Nested-PCR realizada em amostras de DNA obtidas a partir de carrapatos coletados demonstraram resultados negativos. Apesar das tentativas para amplificar o DNA de B. burgdorferi a partir de carrapatos não tenha sido bem sucedido, a presença de soroatividade em vertebrados sugere a possibilidade de espécies de Borrelia circulando nestas regiões. Mais pesquisas são necessárias para fornecer informações sobre a presença de Borrelia em território brasileiro e sua associação com a Síndrome de Baggio-Yoshinari.

Distribución de la concentración inhibitoria mínima y puntos de corte "wild-type" en bacterias de origen animal en Argentina / Wild-typeminimal inhibitory concentration distributions in bacteria of animal origin in Argentina

El objetivo de este estudio fue determinar los patrones de resistencia antimicrobiana en bacterias indicadoras aisladas de muestras fecales de animales domésticos. La concentración inhibitoria mínima (CIM) fue determinada por el método de dilución en agar. El criterio de interpretación usado se basó en la distribución de la CIM y el punto de corte epidemiológico (ECOFF o ECV) de acuerdo con los datos del European Committee on Antimicrobial Susceptibility Testing (EUCAST). Los resultados obtenidos de 237 aislamientos de Escherichia coli mostraron sensibilidad reducida a ampicilina, estreptomicina y tetraciclina, antimicrobianos comúnmente usados en porcinos y aves de explotación intensiva. Con respecto a todas las especies del género Enterococcus spp., solo existe ECOFF o ECV para la vancomicina. De los 173 Enterococcus spp. aislados, sólo uno presentó sensibilidad reducida a dicho agente y fue categorizado como población 'non-wild-type' (NWT). Este es el primer informe en Argentina que presenta datos de puntos de corte epidemiológico en bacterias animales

The aim of this study was to determine the antimicrobial resistance profiles of indicator bacteria isolated from domestic animal feces. Minimal inhibitory concentration (MIC) was determined by agar dilution. Interpretative criteria on the basis of wild-type MIC distributions and epidemiological cutoff values (ECOFF or ECV) were used according to the 'European Committee on Antimicrobial Susceptibility Testing' (EUCAST) data. Results from 237 isolates of Escherichia coli showed reduced susceptibility for ampicillin, streptomycin and tetracycline, the antimicrobials commonly used in intensive breeding of pigs and hens. Regarding all the species of the genus Enterococcus spp., there are only ECOFF or ECV for vancomycin. Of the 173 Enterococcus spp. isolated, only one showed reduced susceptibility to vancomycin and was classifi ed as 'non-wild-type' (NWT) population. This is the fi rst report in Argentina showing data of epidemiological cutoff values in animal bacteria

Introducción. Los ectoparásitos son los principales vectores de rickettsiosis. En Panamá se tienen escasos datos sobre los artrópodos que pudieran considerarse vectores o reservorios. Objetivos. Presentar datos sobre la presencia de Rickettsia spp. en ectoparásitos de fauna silvestre y animales domésticos en la Reserva Natural Privada Cerro Chucantí y poblados vecinos. Materiales y métodos. Se revisaron 9 personas, 95 mamíferos domésticos y 48 silvestres. Los animales domésticos se examinaron con anuencia del propietario, mientras que la fauna silvestre se capturó con trampas Sherman y Tomahawk. Se extrajeron 21 especies de ectoparásitos: pulgas, piojos, garrapatas y otros ácaros, los cuales se preservaron en etanol al 95 %. Se extrajo material genético de garrapatas y pulgas para ser analizado por técnicas moleculares en la detección de Rickettsia spp. Resultados. Se practicaron 425 reacciones de PCR, de las cuales, 270 resultaron negativas y 155 positivas. De las positivas, 86 amplificaron para el gen gltA (55 % de las positivas); de estos también amplificaron 41 (26 %) para ompA. Se encontró material genético de Rickettsia amblyommii, en garrapatas de caballos (Amblyomma cajennense, Dermacentor nitens), de perros (Rhipicephalus sanguineus) y ninfas de Amblyomma recolectadas en el bosque. Además, se detectó ADN de R. felis en pulgas Ctenocephalides felis de perros. Conclusiones. Se pudo detectar la presencia de R. amblyommii y R. felis en garrapatas y pulgas de animales domésticos de los poblados cercanos a Cerro Chucantí, aun cuando no se pudo encontrar material genético de Rickettsia en ectoparásitos de la fauna silvestre.

Introduction. Ectoparasites are the main vectors of rickettsiosis. In Panama, however, limited data are available concerning the arthropod species that serve as vectors or reservoirs. Objectives. Data are presented concerning the presence of Rickettsia in ectoparasites of wildlife and domestic animals in the Cerro Chucantí private nature reserve and in neighboring villages. Materials and methods. Nine humans, 95 domestic mammals and 48 wild mammals were examined. Twenty-one species of ectoparasites were obtained, including fleas, lice, ticks and mites. These were preserved in 95% ethanol. Later, the DNA was extracted from the ticks and fleas and analyzed by molecular techniques to detect presence of Rickettsia. Results. Of a total of 425 PCR reactions, 270 were positive for Rickettsia and 155 negative. Among the positive samples, 86 PCR amplified for the gltA gene (55% of positives) and 41 of these also amplified the ompA gene. DNA of Rickettsiaamblyommii was found in horses ticks (Amblyomma cajennense, Dermacentor nitens), dogs ticks (Rhipicephalus sanguineus) and free living nymphs in the forest. Additionally, DNA of R. felis was found in fleas from dogs Ctenocephalides felis. Conclusions. The presence of R. amblyommii and R. felis was detected in ticks and fleas of domestic animals in villages near Cerro Chucanti; however no Rickettsia DNA was found in ectoparasites of non-domestic wildlife.

Multiple-locus variable-number tandem repeat analysis of reference strains used for the diagnosis of leptospirosis in Argentina / Multiple-locus variable-number tandem repeat analysis de cepas de referencia usadas para el diagnóstico de leptospirosis en Argentina

Leptospirosis is a worldwide zoonosis caused by a spirochete that belongs to the genus Leptospira. In the last years, new methods, such as the PCR-based multiple-locus variable-number tandem repeat analysis (MLVA), have been developed for the genotyping of leptospires. In the present work, the MLVA patterns for all reference strains used in Argentina for bovine, ovine, porcine, equine, caprine and canine leptospirosis diagnosis, as well as in human and wild animal diagnosis, were obtained. MLVA results are presented in such a way that they can be readily used for the identifcation of these strains by the simple and direct comparison of agarose gels. Making the use and interpretation of the MLVA for leptospires typing easier will help increase the use of this method as a routine procedure for human and animal diagnosis, for epidemiological studies, vaccine control and other applications.

La leptospirosis es una zoonosis de distribución global causada por una espiroqueta perteneciente al género Leptospira. En los últimos años se han desarrollado nuevos métodos para la genotipifcación de las leptospiras, entre ellos el denominado multiple-locus variable-number tandem repeat analysis (MLVA). En este trabajo se obtuvieron los patrones de MLVA de todas las cepas de referencia utilizadas en la Argentina para el diagnóstico de leptospirosis en bovinos, ovinos, porcinos, equinos, caprinos y perros, y que también son utilizadas en el diagnóstico de leptospirosis en humanos y en animales salvajes. Los resultados del MLVA se muestran de manera tal que pueden ser fácilmente utilizados para la identifcación de estas cepas por simple comparación visual de geles de agarosa. Al facilitar el uso y la interpretación del MLVA para la tipifcación de leptospiras, se ayudará a difundir la utilización rutinaria de este método en el diagnóstico humano y animal, en estudios epidemiológicos y para el control de vacunas, entre otras aplicaciones.

Dermatophytoses in domesticated animals / Dermatofitoses em animais domésticos

Dermatophytes are among the most frequent causes of ringworm infections in domesticated animals. They are known to serve as reservoirs of the zoophilic dermatophytes and these infections have important zoonotic implication. In Nigeria and probably West Africa, there are not many studies on the incidence of dermatophytosis in domesticated animals. In the current study, 538 domesticated animals with clinically suggestive lesions were investigated for dermatophytes. Identification of dermatophyte species was performed by macro- and micro morphological examination of colonies and by biochemical methods. In the cases of isolates that had atypical morphology and/or biochemical test results, the rDNA internal transcribed spacer region 2 (ITS 2) sequencing was performed. Out of this number, 214 (39.8 percent) were found to be colonized by a variety of ten species of dermatophytes. M. canis was the most frequently isolated species (37.4 percent), followed by T. mentagrophytes (22.9 percent) and T. verrucosum (15.9 percent). M. persicolor and T. gallinae were jointly the least species isolated with a frequency of 0.55 percent respectively. The recovery of dermatophyte isolates previously shown to be common etiological agents of dermatophytosis especially from children in the same region suggests that animal to human transmission may be common. Possible implications and recommendations are discussed.

Dermatófitos estão entre as causas mais frequentes de infecções tipo larva migrans em animais domésticos. Eles são conhecidos como reservatórios de dermatófitos zoófilos e estas infecções têm implicações zoonóticas importantes. Na Nigéria e provavelmente no Oeste da África não existem muitos estudos sobre a incidência de dermatofitose em animais domésticos. No presente estudo, 538 animais domésticos com lesões clinicamente sugestivas foram investigados para dermatófitos. Identificação de espécies de dermatófito foi feita pelo exame macro e microscópico morfológico de colônias e por métodos bioquímicos. No caso de isolados com morfologia atípica e/ou resultados de testes bioquímicos, sequenciamento da região 2 transcrita (ITS-2) do rDNA foi feita. Dos casos, 214 (39,8 por cento) foram colonizados por uma variedade de 10 espécies de dermatófitos. M. canis foi a espécie isolada mais frequente (37,4 por cento) seguida por T. mentagrophytes (22,9 por cento) e de T. verrucosum (15,9 por cento). M. persicolor e T. gallinae foram juntos as menos frequentes espécies isoladas (0,55 por cento respectivamente). O isolamento destes dermatófitos que são agentes etiológicos comuns de dermatofitoses especialmente de crianças da mesma região sugere que a transmissão de animais para humanos possa ser comum. Possíveis implicações e recomendações são discutidas.

Isolation of Mycobacterium bovis & M. tuberculosis from cattle of some farms in north India--possible relevance in human health.

BACKGROUND & OBJECTIVE: Infection due to Mycobacterium bovis typically occurs in cattle and animals transmit infection to each other. The choice of appropriate clinical specimen is very important for isolation of M. bovis and M. tuberculosis from cattle. The present study reports the isolation of M. tuberculosis and M. bovis from different types of specimens from cattle suspected to be suffering from tuberculosis in certain organized cattle farms in north India. METHODS: A total of 768 specimens (heparinized or EDTA containing blood (162), fine needle aspirates from prescapular lymph gland (PSLG,160), milk (154), pharyngeal swab (PhS, 98), rectal pinch (RP, 97) and faecal sample (97) from 161 cattle of organized cattle farms in north India suspected to be suffering from tuberculosis were analyzed. After decontamination by modified Petroff's method isolation of M.tuberculosis complex was done on Lowenstein-Jensen medium (with and without pyruvate). The culture isolates were identified as M. tuberculosis and M. bovis on the basis of biochemical tests. RESULTS: A total of 54 M. tuberculosis complex isolates were obtained, of them 40 were identified as M.bovis and 14 as M. tuberculosis. M.bovis were isolated from 12 of 38 animals in group A (Tuberculin +ve with signs of tuberculosis), 7 of 37 animals in group B (Tuberculin +ve and apparently healthy), 9 of 21 group C animals in (Tuberculin -ve with clinical signs of tuberculosis), 4 of 26 animals in group D (Tuberculin -ve and apparently healthy), 4 of 27 group E animals (having non-mycobacterial infection) and 4 of 12 animals in group F (having clinical signs such as debilitated condition, cough, decreasing milk production, etc). Maximum number of M. bovis (19/40, 47.5%) and M. tuberculosis (5/14, 35.7%) isolates were grown from prescapular lymph gland biopsy (PSLG) followed by blood from which 9/40 (22.5%) M. bovis and 4/14 (28.5%) M. tuberculosis were isolated. M. bovis [6/40(15%)] and M. tuberculosis [4/14(28.5%)] were also isolated from milk. Only 3/40 (7.5%) isolates of M.bovis could be isolated from 97 rectal pinch followed by 98 pharyngeal swab 2/40 (5%) and 97 fecal samples 1/40 (2.5%) while 1/14 (7.1%) M.tuberculosis isolates were obtained from pharyngeal swab. INTERPRETATION & CONCLUSION: Among the samples analyzed, PSLG was found to be most suitable specimen for isolation of M. tuberculosis complex from cattle and is thus of diagnostic importance. M. bovis in milk indicates the need to investigate the transmission to human in such settings. Isolation of M. bovis and/or M. tuberculosis from apparently healthy cattle indicates sub-clinical infection in the herd. Further, isolation of a significant number of M. tuberculosis from cattle suggests possible human-to-cattle transmission which need to be confirmed by prospective studies including tools like DNA fingerprinting.

[Presence and excretion of escherichia coli 0157: H7 by the livestock and their prevalence in the foodstuffs of animal origin]

Escherichia coli producing of Shiga-toxins and more particularly serogroupe 0157:H7 are currently recognized like pathogenic the emergent significant ones in public health. These bacteria were detected at a great number of animal species without the latter presenting clinical signs of disease. However, the principal tank seems to be the cattle population. The prevalence of E. coli 0157:H7 in the samples of deposit of the bovines varied from 4,8% to 36,8%. The persistence of the strains of STEC in the livestock is due, on the one hand, with the intestinal bearing by the animals, and on the other hand, with the contamination of the grounds and water starting from the animal manure being able to be at the origin of a contamination of food. Moreover, the persistence of germ in the animals depends on several factors to knowing: seasonal variation, mode of watering and food. The risk of contamination of the food products of animal origin is a function of the importance of the animal bearing, but also of the respect of the procedures of hygiene applied in particular in slaughter-house and in the workshops of transformation

Hongos queratinofílicos oportunistas en el pelaje de gatos domésticos (Felix domesticus) en la ciudad de Valparaíso / Opportunistic keratinophilic fungi in the fur of domestic cats (Felix domesticus) in the city of Valparaiso

En la ciudad de Valparaíso, se analizó mediante la técnica del tapete, la presencia de hongos queratinofílicos oportunistas en el pelaje de 198 gatos domésticos aparentemente sanos (96 mascotas y 102 de vida libre). Las siembras se efectuaron en duplicado en placas de Petri con agar Sabouraud glucosado incubándose en oscuridad a 35 C durante 15 días. Se consideraron las variables, estilo de vida, edad, tipo de pelaje, sexo y época estacional, de las cuales sólo las dos primeras presentaron diferencias significativas en los taxa aislados. Un total de 130 individuos (65.6 por ciento) fueron positivos a hongos filamentosos; 77 (59.2 por ciento) correspondieron a gatos de vida libre y 53 (40.8 por ciento) a gatos mascota. Se obtuvieron 372 aislados fúngicos, de los cuales 335 (90.1 por ciento) se consideraron como oportunistas, distribuidos en 22 géneros y 23 especies. De estos, 287 (77.1 por ciento) se presentaron en gatos de vida libre y 85 (22.8 por ciento) en mascotas. Los géneros dominantes fueron Aspergillus (53.5 por ciento), Scopulariopsis (19.9 por ciento), Fusarium (4,6 por ciento) y el complex Alternaria alternata (3,8 por ciento). Aspergillus, fue representado por 10 taxa, destacando A. flavus (15,9 por ciento) y A. niger var. niger (13.4 por ciento) y con menores frecuencias A.terreus, A. fumigatus, A.niger var. phoenicis y Emeri-cella nidulans (A. nidulans). A. flavus y A. niger var. niger, se aislaron mayoritariamente en gatos de vida libre y lo mismo sucede con prácticamente todas las especies del género. Scopulariopsis presentó solo 2 especies S.brevicaulis y S. candida. La primera fue la especie con mayor número de aislamientos (18 por ciento) y la de mayor presencia en gatos de vida libre (77.9 por ciento), mientras la segunda fue esporádica (1,6 por ciento). Debe destacarse, por su rareza, que una cepa de S. brevicaulis creció en cultivos asociada a su teleomorfo Microascus brevicaulis. Los Onygenales fueron escasamente representados por...

In the city of Valparaíso the presence of opportunistic fungi in the fur of 198 apparently healthy domestic cats (96 pets and 102 wild cats) was analyzed by means of the mat technique. Cultures were prepared in duplicate on Petri plates using glucosate Sabouraud agar and were incubated at 35C in the dark for 15 days. Factors such as variables, style of life, age, kind of fur, sex and seasonal period were considered, after which only the first two factors exhibited significant differences in the isolated taxa. A total of 130 specimen (65,6 percent) resulted positive to filamentous fungi; being 77 (59,2 percent) wild cats and 53 (40,8 percent) pet cats. Three hundred and seventy two fungal isolates were obtained, 335 of which (90,1 percent) were considered as opportunistic, distributed in 22 genera and 23 species. Among these, 287 (77,1 percent ) were detected in wild cats and 85 (22,8 percent) in pets. Dominant genera were Aspergillus (53,5 percent), Scopulariopsis (19,9 percent), Fusarium (4,6& and the complex Alternaria alternata (3,8 percent): Aspergillus was represented by 10 taxa, A.flavus (15,9 percent) and A. niger var. niger (13,4 percent) exhibiting the highest frequency whereas A.terreus, A. fumigatus, A.niger var. phoenicis and Emericella nidulans (A. nidulans) showed the least occurrence. A.flavus and A.niger var.niger were mostly isolated from wild cats and this is true in the case of all species of the genus. Scopulariopsis revealed only two species, S.brevicaulis and S.candida. The former was the species with the highest number of isolations (18 percent) together with the highest occurrence in wild cats (77,9 percent), while the latter was sporadic. (1,6 percent). Now then, it must be pointed out, due to its rareness, that a strain of S.brevicaulis grew in cultures associated to its teleomorph Microascus brevicaulis. Onygenales were scarcely represented by...

Analysis of gyrA mutations related to quinolone resistance in Escherichia coli isolates originating from pet, human, vegetable and ice in Bangkok and vicinity.

Escherichia coli was used to investigate quinolone resistance and mutations in gyrA gene of E. coli isolated from pet (dog and cat), human (pet's owner), vegetable and edible ice in Bangkok and vicinity. Susceptibility test for nalidixic acid (NA) showed similar percent resistance among the sample sources but a lower ciprofloxacin (CIP) resistance was found particularly in human source. Mutations within quinolone resistance determining region of gyrA gene analyzed using non-radioactive single-strand conformation polymorphism (SSCP) and sequencing showed 10 different SSCP patterns. E. coli isolates from pet, vegetable and ice showed more variety of patterns than strains isolated from human. Four out of 10 SSCP patterns were identified as having mutations in amino acids positions 83 (Ser to Leu) and position 87 (Asp to Asn). These mutations were observed only in NA-resistant strains and combined mutations were observed only in E. coli isolated from humans and pets. As only 24% of NA- and CIP-resistant E coli isolates contained gyrA mutations, other quinolone resistant mechanisms may be involved. Nevertheless, gyrA mutations may be used to monitor nalidixid acid resistance in E. coli.

Knowledge, attitude and practices about zoonoses with reference to Campylobacteriosis in a rural area of West Bengal.

Campylobacteriosis is a leading cause of zoonotic diarrhoea in the developed as well as developing countries. Domestic animals particularly the poultry act as a source of human infections. Domestic animal rearing is a very common practice in India particularly in rural areas. The present study of KAP of Zoonosis showed 68.2 % of 500 families interviewed did not have knowledge about zoonotic diseases in rural Bengal and not a single family had any idea of Campylobacter infections.

El rol epidemiológico de las mascotas en el ciclo de transmisión urbana de cepas STEC / Epidemiological role of pets in urban transmission cycle of STEC

Escherichia coli is an important constitutional element of both animal's and men's microbiote. Rumiants in general and bovine in particular have been pointed out as reservoirs of shigatoxigenic (STEC) and enterohemorragic strains (EHEC). These strains are rarely reported in pets isolations and are badly documented. Revisions of the pathogenic role of E. coli in small animals, particulary based on intestinal and urogenital isolations, involve in a very low proportion the STEC strains. In dogs, ocasional isolations are reported, from feces coming from both healthy and diarreic dogs. The STEC intestinal strains prevalence in dogs and cats from urban centers, based on the habit of including regular or ocasional raw meat in their diet, should not be understimated.

epidemiological profile of brucellosis in Tabuk Province, Saudi Arabia

All 137 brucellosis cases occurring in Tabuk Province, Saudi Arabia in 1997 were studied retrospectively. Brucella agglutination titre of > or = 1/80, or rising titre plus history of typical signs and symptoms were considered evidence of infection. The incidence rate was 34/100,000, mean age 33.8 +/- 13.9 years [range: 3-72 years] and male:female ratio 1.8:1. There were 63.5% of cases rurally resident, 58.4% kept animals at home or elsewhere, 27.0% worked with animals and/or on farms, and 88.3% reported a history of raw milk ingestion. The most common infecting agents were Brucella melitensis, B. abortus and B. suis. Splenomegaly and hepatomegaly were detected in 25.5% and 22.6% of cases respectively

Borrelioses, agentes e vetores / Borrelioses, agents and vectors: a review

As borrelioses säo enfermidades infecciosas determinadas por espiroquetas do gênero Borrelia, agentes transmissíveis, principalmente, por carrapatos aos animais e/ou ao homem. Nesta revisäo säo apresentadas e discutidas as enfermidades determinadas por borrélias, bem como as características gerais das espiroquetas, os aspectos relacionados a transmissäo por artrópodes, as enfermidades nos animais domésticos e silvestres, quanto aos aspectos biológicos e patológicos, a doença de Lyme como principal zoonose do grupo, a associaçäo de borrélia com outros agentes hematozoários e os métodos diagnósticos e a epidemiologia comparativa entre dados obtidos no Brasil com os de outros países. Estas borrelioses possuem características patológicas, clínicas e epidemiológicas variadas de acordo à regiäo fisiográfica, devido à existência de distintas espécies, genoespécies e cepas; estes aspectos variam ainda em funçäo dos artrópodes vetores, da interaçäo vetor-patógeno e dos ecossistemas distintos.

Prevalence of clostridial microorganisms in domestic rabbits at Giza governorate

Clostridial microorganisms were recovered from 126 out of 358 [35.2%] examined rabbits, either with gross normal conditions or suffered from intestinal disorders. Baladi rabbits showed the highest incidence, followed by California and Boscat breeds. The lowest recovery was recorded from New Zeal and white breed. C. perfringens and C. difficile were identified in high and low rates, respectively, from both apparently healthy and diarrheic rabbits. However, C. tertium was recovered only from diseased ones. The toxigenic C. perfringens isolates were types A, E and D in descending manner. Moreover, four rabbits recorded mixed A and D types. Type A produced high lecithinase, hyaluronidase and hemolytic activities, but the fibrinolytic activity was 70%. Type D was completely fibrinolytic, lowest producer for both lecithinase and hemolysin and non- hyaluronidase producer. On the other h and, type E activities were moderate
