ABSTRACT

Abstract Feline Bartonella can be transmitted to humans through cat scratches or bites, and between cats, by the flea Ctenocephalides felis. The study was carried out in order to investigate the occurrence of Bartonella DNA in cats living in shelters and their ectoparasites and the relationship between the infection status of cats and ectoparasites they host. Bartonella DNA was detected in 47.8% of the cat blood samples, 18.3% of C. felis fleas, 13.3% of flea egg pools and 12.5% of lice pools. B. henselae and B. clarridgeiae DNA were detected in cat fleas, while B. henselae, B. clarridgeiae and B. koehlerae were found in blood samples from bacteremic cats. Cats infested by positive ectoparasites showed approximately twice the odds of being infected. Our results indicate that shelter cats have high prevalence of Bartonella species that are known to be human pathogens. This highlights the importance of controlling infestations by ectoparasites to avoid cat and human infection.


Resumo Algumas espécies de Bartonella têm os felinos como principais hospedeiros reservatórios. Tais patógenos são transmitidos ao homem por intermédio da arranhadura ou mordedura de gatos e entre os gatos, por meio da pulga Ctenocephalides felis. O objetivo deste estudo foi investigar a ocorrência de DNA de Bartonella spp. em gatos de abrigos e seus ectoparasitas e a relação entre o estado de infecção dos gatos e dos ectoparasitas albergados por estes. Material genético bacteriano foi detectado em 47,8% das amostras de sangue de gatos, 18,3% das pulgas C. felis, 13,3% dos "pools" de ovos de pulgas e 12,5% dos "pools" de piolhos. DNA de B. henselae e B. clarridgeiae foi detectado em pulgas, e B. henselae, B. clarridgeiae e B. koehlerae, em amostras de sangue de gatos. Gatos infestados por ectoparasitas que carreavam DNA de Bartonella spp. demonstraram aproximadamente o dobro de chance de estarem infectados. Esses resultados indicam que os gatos de abrigos têm alta prevalência de infecção por espécies de Bartonella, capazes de causar doenças no homem. E também destacam a importância do controle e prevenção da infestação por ectoparasitas, no intuito de prevenir a infecção em gatos e humanos.

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

Objetivo. Identificar especies de ectoparásitos encontrados parasitando naturalmente un Oso melero, el cual fue encontrado muriendo en una vía cercana al pueblo de Bobare, estado Lara, Venezuela. Materiales y métodos. Al ingresar el animal a la sala de anatomía del DCV-UCLA para ser sometido a la técnica de taxidermia, se procedió a revisar a través de la palpación toda la superficie corporal del Oso, con la finalidad de tomar muestras de ectoparásitos presentes en el hospedador; los especímenes encontrados fueron colocados en un envase de vidrio conservados en alcohol isopropílico y posteriormente fueron llevados al Laboratorio de Parasitología Veterinaria del DCV-UCLA para su identificación taxonómica. Los ectoparásitos fueron observados en lupa estereoscópica y clasificados con ayuda de claves taxonómicas. Resultados. Se identificaron dos especies de artrópodos infestando naturalmente el Oso Melero, de las cuales se encuentra una garrapata macho clasificada como Amblyomma nodosum; y una pulga hembra identificada como Pulex irritans. Conclusiones. Estos artrópodos se han reportado parasitando naturalmente algunas especies de mamíferos, dentro de los cuales el Oso Melero se ha visto afectado por la acción de estos ectoparásitos; en Venezuela es el primer reporte de Pulex irritans afectando esta especie animal.


Objectives. Identify species of ectoparasites found naturally parasitizing an anteater, which was found dying on the roadside close to Bobare Village, State of Lara, Venezuela. Materials and methods. A dead anteater was brought to the anatomy Lab of the Decanato de Ciencias Veterinarias (DCV), Universidad Centroccidental “Lisandro Alvarado” (UCLA) for taxidermic purposes. First, all the skin and hairy areas of the animal were manually checked looking for ectoparasites; secondly, all detected specimens were collected, and placed in vials containing a solution of isopropilic alcohol 70°. Following this procedure, the vials were taken to the Veterinary Parasitology Laboratory at DCV-UCLA to accomplish the taxonomic identification under a stereoscopic microscope, and with taxonomic keys. Results. Two specimens of arthropods were found, the first one was a male tick identified as Amblyomma nodosum, and the other one was a female flea of the genera Pulex irritans Conclusions. These ectoparasites have been reported as natural parasites of other mammals, and among them the anteaters have been often found parasitized by these arthropods. In Venezuela this is the first case of a Pulex irritans infecting Tamandua tetradactyla.

ABSTRACT

Ctenocephalides felis felis is one of the most important ectoparasites of dogs and cats throughout the world, because of its geographical distribution, dual parasitological action as an infesting agent and a vector of diseases, the economic losses and the acquired resistance against common insecticides. In Brazil, it surpasses Ctenocephalides canis in distribution, number of host species infested, prevalence and epidemiological importance. However, in some studies the species have been misidentified on the basis of their morphological characters included in taxonomic keys. The morphological variations of chaetotaxy, especially those on the dorsal margin of the hind tibia and lateral metanotal area (LMA), found in certain specimens, have sometimes been erroneously treated as hybrids, in spite of the nonexistence of the two species of Ctenocephalides in the same municipality or region. This review focuses on the characteristics used for interspecific diagnosis and intraspecific variations found between the species. Data on distribution, hosts, prevalence and parasitological action are also presented as an auxiliary means for recognizing the species.(AU)


Ctenocephalides felis felis é um dos mais importantes ectoparasitos de cães e gatos no mundo inteiro, em virtude de sua distribuição geográfica, dupla ação parasitológica como agente infestante e vetor de doenças, perdas econômicas e resistência adquirida contra inseticidas comuns. No Brasil, ela sobrepuja Ctenocephalides canis em distribuição, número de espécies de hospedeiros infestadas, prevalência e importância epidemiológica. Todavia, em alguns estudos, as espécies têm sido incorretamente identificadas pelos caracteres morfológicos incluídos em chaves taxonômicas. As variações morfológicas de quetotaxia, especialmente aquelas da margem dorsal da tibia posterior e área metanotal lateral (LMA) encontradas em certos exemplares, algumas vezes têm sido erroneamente consideradas como híbridas, a despeito da inexistência das duas espécies em um mesmo município ou região. Esta revisão aborda as características utilizadas para o diagnóstico interespecífico e variações intra-específicas encontradas entre as espécies. Dados sobre distribuição, hospedeiros, prevalência e atuação parasitológica são também apresentados como um meio auxiliar para o reconhecimento das espécies.(AU)

ABSTRACT

Rickettsia typhi is an intracellular bacteria who causes murine typhus. His importance is reflected in the high frequency founding specific antibodies against R. typhi in several worldwide seroepidemiological studies, the seroprevalence ranging between 3-36%. Natural reservoirs of Rickettsia typhi are rats (some species belonging the Rattus Genus) and fleas (Xenopsylla cheopis) are his vector. This infection is associated with overcrowding, pollution and poor hygiene. Typically presents fever, headache, rash on trunk and extremities, in some cases may occur organspecific complications, affecting liver, kidney, lung or brain. Initially the disease is very similar to other diseases, is very common to confuse the murine typhus with Dengue fever, therefore, ignorance of the disease is a factor related to complications or non-specific treatments for the resolution of this infection. This paper presents the most relevant information to consider about the rickettsiosis caused by Rickettsia typhi

ABSTRACT

Raptorial birds harbor a variety of ectoparasites and the mayority of them are host specific. The aim of this study was to identify the ectoparasites of captive birds of prey from Mexico, as well as to verify their impact in the health of infested birds. Raptorial birds were confiscated and kept in captivity at the Centro de Investigación y Conservación de Vida Silvestre (CIVS) in Los Reyes La Paz, Mexico State. Seventy-four birds of prey (66 Falconiformes and eigth Strigiformes) of 15 species were examined for the presence of ectoparasites. We examined both juvenile and adult birds from both sexes. The overall prevalence was 16.2%; 66.7% of raptors were infested with a single type of external parasite. Lice were the most prevalent ectoparasites (91.7%), followed by feather mites and fleas (8.3%). Degeeriella fulva (72.7%), Craspedorrhynchus sp. (45.4%) and Strigiphilus aitkeni (9.1%) (Ischnocera, Philopteridae) were recovered from wings, head and neck regions of red-tailed hawk (Buteo jamaicensis), Swainson’s hawk (B. swainsoni), Harris’s hawk (Parabuteo unicinctus) and Barn owl (Tyto alba). Low lice infestation level was observed. Nymphs and females of feather mites Kramerella sp. (Pterolichoidea, Kramerellidae) were recovered solely from Barn owl (T. alba); while one Caracara (Caracara cheriway) was infested by the sticktight flea Echidnophaga gallinacea (Siphonaptera, Pulicidae). No clinical signs were observed in any infested bird. Probably the periodic use of organophosphorates was responsible of the low prevalence and lice infestation levels. The diversity of external parasites illustrates the importance of detailed revision of incoming and long-term captive raptors as part of responsible captive management. Five new hosts and geographic records are presented. Rev. Biol. Trop. 59 (3): 1257-1264. Epub 2011 September 01.


Las aves rapaces albergan una gran variedad de ectoparásitos y la mayoría de ellos son específicos de acogida. El objetivo de este estudio fue identificar los ectoparásitos de aves de presa en cautiverio en México y verificar su impacto en la salud de las aves. Se estudiaron 74 rapaces (66 Falconiformes y ocho Strigiformes) de 15 especies, juveniles y adultos de ambos sexos que fueron confiscadas y mantenidas en el Centro de Investigación y Conservación de Vida Silvestre (CIVS) en Los Reyes La Paz (20º22’ N, 98º59’ W), estado de México. La prevalencia fue de 16.2%; 66.7% de las rapaces estaban infestadas por un único tipo de ectoparásito. Los piojos fueron los más prevalentes (91.7%), seguidos por los ácaros y las pulgas (8.3%). Los piojos Degeeriela fulva (72.7%), Craspedorhynchus sp. (45.4%) y Strigiphilus aitkeni (9.1%) fueron extraídos de las alas, cabeza y cuello de aguililla cola-roja (Buteo jamaicensis), aguililla migratoria (B. swainsoni), aguililla de Harris (Parabuteo unicinctus) y lechuza de campanario (Tyto alba). El ácaro Kramerella sp. fue extaído de T. alba; mientras que un Caracara (Caracara cheriway) estaba infestado por la pulga Echidnophaga gallinacea. No se observaron signos clínicos en ninguna de las aves infestadas. Probablemente el uso periódico de organofosforatos fue el responsable de la baja prevalencia y de los niveles de ingesta de piojos. La diversidad de ectoparásitos identificados ilustra la importancia de una detallada revisión de las rapaces en cautiverio. Cinco nuevos hospederos y registros geográficos son presentados.

ABSTRACT

Introducción. La tungiasis, o infestación cutánea por la pulga Tunga penetrans, ocurre en comunidades muy pobres.Objetivo. Presentar la entidad en indígenas del Vaupés. Métodos. En primer lugar, se revisó el tema. Luego, se describió el área y la vivienda de los pacientes afectados; se detectaron los animales infestados con la zoonosis. Se iIustró el aspecto clínico y sus complicaciones y, posteriormente, se trataron los pacientes con creolina. Se logró hacer modificaciones en el piso de las malocas de dos comunidades, con humedad y arcilla, y se impartió educación a la comunidad sobre esta parasitosis. Resultados. El 95% de los 33.000 habitantes del Vaupés son indígenas. Algunos moran en viviendas de piso arenoso, seco, con detritos alimenticios y perros con tungiasis. Entre 1996 y 2007 confirmamos 942 casos del parasitismo. De los indígenas estudiados, 3 a 8 de cada 1.000 y 62% de los perros, presentaban tungiasis. Los pies se vieron afectados en 98% de los pacientes. Se presentaron casos graves con más de 20 lesiones, en niños y ancianos. Como complicaciones, se presentaron: infección secundaria, dolor, anoniquia, deformación y amputación de los dedos de los pies e imposibilidad para la marcha. Hubo sepsis mortal en tres pacientes. No se presentaron casos de tétanos. Los baños con creolina y la extracción del parásito fueron curativos, en hombres y animales. La modificación de los pisos redujo a cero la enfermedad en una comunidad. Conclusiones. La enfermedad es intradomiciliaria. El piso de la vivienda y la convivencia con perros infestados son ideales para adquirirla. La creolina, la humectación del piso y el cubrirlo con arcilla controlaron un foco de la enfermedad, actividad que podría generalizarse. Ésta es la primera investigación colombiana sobre la tungiasis, entidad conocida en Colombia desde que afectó a los soldados de Gonzalo Jiménez de Quesada, fundador de Santafé de Bogotá en 1538.


Introduction. Tungiasis, the skin infestation with the flea Tunga penetrans, occurs in poor communities.Objective. To present a study of this condition among native Amerindians from Vaupés (Colombia). Methods. After reviewing this topic, we present a description of the geographic area and the housing of the affected subjects; animal carriers infected with this zoonosis were also detected. We illustrate the clinical aspects and complications. Patients were treated with creolin (liquid cresol). We modified the floor of malocas in two communities using wet clay, and we educated the community on this parasite. Results. About 95% of the 33,000 inhabitants of Vaupés are native Amerindians. Some households have dry sandy floors, where food leftovers attract dogs infested with tungiasis. From 1996 to 2007 we confirmed 942 human cases of this parasitic disease. Among the native communities, 3 to 8 per 1,000 persons and 62% of the dogs have tungiasis. Feet were affected in 98% of the patients. Severe cases, with more than 20 lesions, occurred among children and the elderly. Complications included secondary infections, pain, anonychia (loss of toenails), toe deformities, amputation of toes and walking problems. Three patients died as a result of sepsis originating from toe infections. Topic use of liquid creolin and extraction of the parasite cured the problem in humans and dogs. Floor modifications eradicated the problem in one community. Conclusions. Tungiasis is an intradomiciliary disease. Favorable conditions for infestations include dry sandy floors and infected dogs. Treatment of the floors with creolin and wet clay resulted in control of one focus of the disease; this method could be applied more widely. This is the first known research study on tungiasis in Colombia, a disease that affected the soldiers of the Spanish Conquistador Gonzalo Jiménez de Quesada in the 1500s.

ABSTRACT

A tungíase é ectoparasitose causada pela penetração da Tunga penetrans na pele do hospedeiro. A infestação por essa pulga está associada à pobreza e ocorre em comunidades carentes na América do Sul e Central, no Caribe e na África sul-sahariana. No Brasil, é mais prevalente em assentamentos urbanos precários, áreas rurais e comunidades de pescadores em todo o país. O tratamento consiste na retirada dos parasitas e, nos casos com infecção secundária, antibioticoterapia. Até o momento, não há droga no mercado com eficácia clínica satisfatória. Relata-se caso de tungíase disseminada tratada com ivermectina oral.


Tungiasis is an ectoparasitic infection caused by the penetration of the sand flea Tunga penetrans into the skin of the host. Flea infestation is associated with poverty and occurs in resource-poor communities in South and Central America, the Caribbean and Sub-Saharan Africa. In Brazil, it is widespread in urban squatter settlements, villages in the rural hinterland and in traditional fishing communities along the coast. Standard therapy for tungiasis consists of removing the embedded flea with a sterile needle, and using an antibiotic agent in case of secondary infection. At present, there is no drug in the market with satisfactory clinical efficacy. We describe a case of generalized Tunga penetrans infestation that was treated with oral ivermectin.
