ABSTRACT

Abstract This study used serological and molecular methods to investigate the occurrence of vector-borne pathogens (VBP) with zoonotic potential in cats neutered at the University Veterinary Hospital in Canoinhas, Santa Catarina. The combined PCR and serological results revealed that 17 (56.6%) cats were positive for one or more pathogens. The sampled cats had antibodies to Ehrlichia spp. (7/30), Anaplasma phagocytophilum (3/30) and Leishmania infantum (2/30). The PCR assay detected DNA closely related to Ehrlichia canis in 6/30 cats, Mycoplasma haemofelis in 2/30 cats, A. phagocytophilum and Cytauxzoon sp. in one cat each. While Bartonella clarridgeiae and B. henselae were detected in two cats each, and B. koehlerae was detected in one cat.


Resumo Como os felinos podem ser parasitados por diversos patógenos transmitidos por vetores (PTV), alguns com caráter zoonótico, este estudo objetivou detectar por métodos sorológicos e moleculares, patógenos transmitidos por vetores hematófagos, em gatos atendidos em um Hospital Veterinário Universitário em Santa Catarina. Os resultados da PCR e da sorologia combinados, revelaram que 17 (56,6%) gatos foram positivos para um ou mais patógenos. Na sorologia, foram positivos 7/30 gatos para Ehrlichia, 3/30 para Anaplasma phagocytophilum e 2/30 para Leishmania infantum. Na PCR foi detectado DNA filogeneticamente associado a: Ehrlichia canis em 6/30 gatos; Mycoplasma haemofelis, em 2/30 gatos; A. phagocytophilum e Cytauxzoon sp. em 1/30 gatos cada. Enquanto Bartonella clarridgeiae e B. henselae foram detectadas, cada uma, em dois gatos, B. koehlerae foi detectada em um gato.

ABSTRACT

Abstract Free-ranging and feral dogs represent a group of unattended companion animals. They impact wild animal populations by predating native species, displacing predators and introducing exotic pathogens. The aim of this work was to describe the molecular occurrence of Rickettsia, Ehrlichia, Anaplasma, Mycoplasma and Bartonella in feral dogs. The study was carried out in the last relict of a protected area in Mexico City. Blood clots samples from 19 dogs were obtained and analyzed for detection of specific fragments of the 16S-rRNA gene for Anaplasma, Ehrlichia and Mycoplasma and citrate synthase (gltA) for Bartonella and Rickettsia. Our results showed that DNA from three bacteria species (Bartonella vinsonii subsp. berkhoffii, Ehrlichia canis and Mycoplasma haemocanis) was present with frequencies ranging from 5.3 to 15.8%. This is the first record of B. vinsonii subsp. berkhoffii and M. haemocanis in dogs from México, and also the first finding of Ehrlichia canis in Mexico City. It is important to perform surveillance of feral dog populations in order to identify the impact of these pathogens on wild animal populations and Public Health in order to establish prevention and protection programs.


Resumo Cães errantes e selvagens representam um grupo de animais de companhia livres. Eles impactam as populações de animais selvagens pela predação de espécies nativas, deslocando predadores e introduzindo patógenos exóticos. O objetivo deste trabalho foi descrever a ocorrência molecular de Rickettsia, Ehrlichia, Anaplasma, Mycoplasma e Bartonella em cães selvagens. O estudo foi realizado no último ecossistema de uma área protegida na Cidade do México. Amostras de coágulos sanguíneos de 19 cães foram obtidas e analisadas para detecção de fragmentos específicos do gene 16S-rRNA para Anaplasma, Ehrlichia e Mycoplasma e citrato sintase (gltA) para Bartonella e Rickettsia. Nossos resultados mostraram que o DNA de três espécies de bactérias (Bartonella vinsonii subsp. berkhoffii, Ehrlichia canis e Mycoplasma haemocanis) estava presente com frequências variando de 5,3 a 15,8%. Este é o primeiro registro de B. vinsonii subsp. berkhoffii e M. haemocanis em cães do México, e também a primeira descrição de Ehrlichia canis na Cidade do México. É importante realizar a vigilância das populações de cães selvagens para identificar o impacto desses patógenos nas populações de animais silvestres e na Saúde Pública, a fim de estabelecer programas de prevenção e proteção.

ABSTRACT

Abstract Bartonellosis are diseases caused by any kind of Bartonella species. The infection manifests as asymptomatic bacteremia to potentially fatal disorders. Many species are pathogenic to humans, but three are responsible for most clinical symptoms: Bartonella bacilliformis, Bartonella quintana, and Bartonella henselae. Peruvian wart, caused by B. bacilliformis, may be indistinguishable from bacillary angiomatosis caused by the other two species. Other cutaneous manifestations include maculo-papular rash in trench fever, papules or nodules in cat scratch disease, and vasculitis (often associated with endocarditis). In addition, febrile morbilliform rash, purpura, urticaria, erythema nodosum, erythema multiforme, erythema marginatus, granuloma annularis, leukocytoclastic vasculitis, granulomatous reactions, and angioproliferative reactions may occur. Considering the broad spectrum of infection and the potential complications associated with Bartonella spp., the infection should be considered by physicians more frequently among the differential diagnoses of idiopathic conditions. Health professionals and researchers often neglected this diseases.

ABSTRACT

ABSTRACT This study verified the occurrence of Bartonella spp. in dogs, cats, wild mammals and their ectoparasites in Petrolina and Lagoa Grande Counties, Pernambuco, located in a semi-arid region in Northeastern Brazil. Anti-Bartonella spp. antibodies were detected by indirect immunofluorescence assay (IFA) in 24.8% of dogs (27/109) and in 15% of cats (6/40). Bartonella sp. DNA was identified by PCR performed on DNA extracted from blood and ectoparasites using primers targeting Bartonella sp. gltA and ribC genes in 100% (9/9) of Pulex irritans from Cerdocyon thous, 57.4% (35/61) of P. irritans from dogs, 2.3% (1/43) of Ctenocephalides felis felis from dogs, 53.3% (24/45) of C. felis felis from cats, and 10% (1/10) of Polyplax spp. from Thrichomys apereoides. DNA sequencing identified Bartonella clarridgeiae and Bartonella henselae in C. felis felis from cats, Bartonella rochalimae in P. irritans from dog and C. thous, and Bartonella vinsoni berkhofii in P. irritans from dog.

ABSTRACT

A novel SYBR® green-real time polymerase chain reaction (qPCR) was developed to detect two Bartonella species, B. henselae and B. clarridgeiae, directly from blood samples. The test was used in blood samples obtained from cats living in animal shelters in Southern Brazil. Results were compared with those obtained by conventional PCR targeting Bartonella spp. Among the 47 samples analyzed, eight were positive using the conventional PCR and 12 were positive using qPCR. Importantly, the new qPCR detected the presence of both B. henselae and B. clarridgeiae in two samples. The results show that the qPCR described here may be a reliable tool for the screening and differentiation of two important Bartonella species.


Um novo teste baseado na reação em cadeia da polimerase em tempo real (qPCR) com SYBR ® Green foi desenvolvido para detectar duas espécies de Bartonella, B. henselae e B. clarridgeiae, diretamente em amostras de sangue. Este teste foi utilizado em amostras de sangue obtidas de gatos que vivem em abrigos de animais do sul do Brasil. Os resultados foram comparados aos obtidos pelo PCR convencional utilizado para a detecção de Bartonella spp. Das 47 amostras analisadas, oito foram positivas no PCR convencional e 12 foram positivas para qPCR. A reação de qPCR, permitiu a detecção da presença simultânea de B. henselae e B. clarridgeiae em duas destas amostras. Os resultados mostram que a qPCR aqui descrita pode ser uma ferramenta confiável para a detecção e diferenciação de duas espécies importantes de Bartonella spp.

ABSTRACT

Hemotrophic mycoplasmas and Bartonella species are important pathogens that circulate between cats and invertebrate hosts, occasionally causing diseases in humans. Nevertheless, there are few reports on occurrences of these agents in cats in Brazil. The present study aimed to detect the presence of hemoplasma and Bartonella DNA by means of PCR and sequencing. FIV antigens and anti-FeLV antibodies, were studied by using a commercial kit on blood and serum samples, respectively, among 46 cats that were sampled during a spaying/neutering campaign conducted in Jaboticabal, SP. Three (6.5%) cats were positive for hemoplasmas: two (4.3%) for 'Candidatus M. haemominutum' and one (2.2%) for both M. haemofelis and 'Candidatus M. turicensis'. One of the two 'Candidatus M. haemominutum'-infected cats was also positive for FeLV antigens and showed antibodies for FIV. Two cats (4.3%) were positive for B. henselae. One of them was also positive for FeLV antigens. Eight cats (17.4%) were positive for FeLV, and just one (2.2%) showed anti-FIV antibodies. Bartonella species and hemoplasmas associated with infection due to retroviruses can circulate among apparently healthy cats.


Micoplasmas hemotróficos e espécies de Bartonella são importantes patógenos que circulam entre gatos e hospedeiros invertebrados, causando ocasionalmente doenças no homem. Apesar disto, poucos são os estudos acerca da ocorrência destes agentes entre gatos no Brasil. O presente estudo objetivou detectar o DNA de hemoplasmas e Bartonella sp. pela PCR e sequenciamento. Antígeno de FIV e anticorpos anti-FeLV foram estudados utilizando um "kit" comercial, em amostras de sangue e soro, respectivamente, de 46 gatos amostrados em uma campanha de castração em Jaboticabal, SP. Três gatos (6,5%) foram positivos para hemoplasmas: dois (4,3%) para 'Candidatus M. haemominutum' e um (2,2%) para M. haemofelis and 'Candidatus M. turicensis'. Um dos gatos positivos para 'Candidatus M. haemominutum' mostrou-se também positivo na detecção de antígeno de FeLV e de anticorpos para FIV. Dois (4,3%) gatos mostraram-se positivos para B. henselae, sendo que um deles também se mostrou positivo para antígeno de FeLV. Oito gatos (17,4%) foram positivos para FeLV, e apenas um gato mostrou anticorpos anti-FIV. Bartonella sp. e hemoplasmas associados à infecção por retrovírus podem circular entre gatos aparentemente saudáveis.

ABSTRACT

Bartonella species are fastidious bacteria that predominantly infect mammalian erythrocytes and endothelial cells and cause long-lasting bacteraemia in their reservoir hosts. Reports that describe the epidemiology of bartonellosis in Brazil are limited. This study aimed to detect and characterise Bartonella spp DNA from cat blood samples in São Luís, Maranhão, north-eastern Brazil. Among 200 cats tested for multiple genes, nine (4.5%) were positive for Bartonella spp: six cats for Bartonella henselae and three for Bartonella clarridgeiae. Based on the phylogenetic analysis of four genes, the B. henselae strain matched strains previously observed in Brazil and was positioned in the same clade as B. henselae isolates from the United States of America. Moreover, sequence alignment demonstrated that the B. clarridgeiae strain detected in the present study was the same as the one recently detected in cats from southern Brazil.

ABSTRACT

La septicemia es una de las principales causas de muerte entre pacientes hospitalizados. El aislamiento del agente causal de la bacteremia a través de los hemocultivos constituye una herramienta de gran utilidad en el proceso diagnóstico. Los hemocultivos pueden ser clasificados según la obtención de la muestra (catéter venoso central, vena periférico), según el tipo de microorganismo (bacterias aerobias, anaerobias o fastidiosas, hongos, micobacterias, virus) o según el sistema utilizado (manual, automatizado). Los nuevos métodos de hemocultivos han permitido ampliar el espectro de microorganismos identificados. Para obtener resultados confiables es necesario que la obtención de la muestra sea adecuada en cuanto al volumen de sangre obtenido, número de hemocultivos, desinfección de la piel y al momento de obtención (comienzo del episodio febril). Para diferenciar entre bacteremia verdadera y colonización se debe considerar el cuadro clínico, el tipo de microorganismo aislado y el número de hemocultivos positivos. La interpretación de un hemocultivo positivo se basa en una adecuada evaluación clínica y en el uso apropiado de las metodologías disponibles

ABSTRACT

En Setiembre de 1988 se realizó un estudio epidemiológico sobre Bartonelosis en los distritos de Masin, Rahuapampa, Huachis, Chaná, Pontó y Huachi en el valle del Puchka, provincia de Huari, Ancash. Se encuestó a 208 pobladores, detectándose entre ellos 7 casos activos de Bartonelosis. A todos se les tomó una muestra de sangre para frotises, hemocultivos y serología. En los 201 personas asintomáticas, se encontró a 77 (38.3 por ciento) portadores asintomáticos de Bartonella bacilliformis. Todas las muestras fueron positivas a la serología teniendo el 91.4 por ciento de la población títulos que oscilaron entre 1/80 y 1/320. Un 12.5 por ciento refirió antecedentes de la enfermedad bartonelósica. Entre los casos clínicos, 6 estuvieron en la fase eruptiva y uno en la fase hemática. Alguno de los casos clínicos y de los portadores se encontraron a más de 3,000 metros de altitud. Se observa que los portadores están en mayor porcentaje entre los que refieren antecedentes y en altitudes más bajas.
