Leishmania (Leishmania) infantum is the zoonotic agent of visceral leishmaniasis (VL), a disease with global distribution. The transmission scenario VL has been undergoing changes worldwide, biologic cycle invading urbanized areas and dispersing parasites into other previously free areas. epidemiological in Brazil dispersed from Northeast to regions country. In this study, an integrative approach, including genotyping Brazilian strains L. (L.) for 14 microsatellite markers reviewing...
A cross-sectional epidemiological study in the extreme-west of state Paraná was carried out to access prevalence, distribution, and risk variables canine Visceral Leishmaniases (cVL). This conducted three areas, two cities far west Parana state: Foz do Iguaçu (FI) Santa Terezinha de Itaipu (STI), along transects between these municipalities. To sample entire urban area, (FI STI) were divided into a grid squares 400 m2 (patch). Among 526 patches, 123 FI, 40 33 STI selected according 'worst...
The aim of this study was to determine the frequency gastrointestinal parasites in dogs and cats Londrina, Paraná. A survey results fecal examinations, technique Faust, Willis, Hoffmann / or direct examination, performed routine Laboratory Parasitology, Department Veterinary Preventive Medicine, State University Londrina period January 2000 December 2011 Clinical 2008 2011. 2668 samples were analyzed, which 2290 (85.83%) 378 (14.17%) cats. Of total, 851 (37,16%) 166 (43,91%) feline positive...
A proximidade da relação homem-animal tem aumentado o risco de transmissão doenças caráter zoonótico. O objetivo desse trabalho foi determinar a prevalência anticorpos IgG anti-Toxoplasma gondii, anti- Leishmania spp. e Leptospira nos cães gatos atendidos pelo Projeto Controle Natalidade (PCN) anos 2004 2012 verificar significância estatística variáveis ambientais população estudo à presença dos agentes infecciosos. Amostras sangue 271 415 foram colhidas por venopunção jugular ou cefálica...
Abstract This study evaluated the seroprevalence of Toxoplasma gondii, Neospora caninum and Leptospira spp. in dogs from Foz do Iguaçu, Paraná, Brazil. Indirect immunofluorescent antibody test was used to detect antibodies anti-T.gondii anti-N. caninum. Immunoenzymatic assay microscopic serum agglutination were for screening anti-Leptospira spp., respectively. The results were: 67.02% samples reactive T.gondii 1.38% N. caninum, both without statistically significant variables. For indicated...
INTRODUCTION: The production of the Montenegro antigen for skin test poses difficulties regarding quality control. Here, we propose that certain animal models reproducing a similar immune response to humans may be used in control production. METHODS: Fifteen Cavia porcellus (guinea pigs) were immunized with Leishmania amazonensis or braziliensis , and, after 30 days, they tested standard antigen. To validate C. as an model tests, eighteen Mesocricetus auratus (hamsters) infected L. 45...
ABSTRACT: The present study aimed to investigate an abortion outbreak in a dairy goat herd the municipality of Arapoti, Parana, Brazil. At beginning outbreak, blood samples were collected from 33 goats with clinical signs; later, whole herd, two cats and dogs. Milk 78 lactating goats. Four environmental soil four feed residue feeders too. Immunofluorescence antibody test (IFA) was used for serodiagnosis, molecular analysis conducted by means polymerase chain reaction (PCR), isolation...
A leishmaniose é uma importante metazoonose causada por protozoários do gênero Leishmania, com ciclo de vida heteroxênico que envolve hospedeiros invertebrados e vertebrados. transmissão ocorre durante o repasto sanguíneo flebotomíneo infectado em animais domésticos silvestres no homem. O cão caracterizado como reservatório protozoário na visceral, já tegumentar americana um hospedeiro errático que, assim homem, se infecta acidentalmente. ainda pode ser considerado sinalizador da presença...
Abstract Canine visceral leishmaniasis (CVL) caused by Leishmania (Leishmania) infantum is transmitted phlebotomine sandflies and a major zoonotic disease in Brazil. Due to the southward expansion of within country central role dogs as urban reservoirs parasite, we have investigated occurrence CVL two municipalities Erval Velho Herval d’Oeste Midwest region Santa Catarina state. Peripheral blood samples from 126 were collected both cities tested for anti-L. antibodies indirect enzyme-linked...
The aim of this study was to evaluate an enzyme-linked immunoassay with recombinant rhoptry protein 2 (ELISA-rROP2) for its ability detect Toxoplasma gondii ROP2-specific IgG in samples from pregnant women. included 236 that were divided into groups according serological screening profiles toxoplasmosis: unexposed (n = 65), probable acute infection 48), possible 58) and exposed the parasite 65). When indirect immunofluorescence assay forT. gondii-specific considered as a reference test,...
Abstract The aim of this study was to investigate the occurrence anti-Leishmania spp. antibodies in dogs from localities city Foz do Iguaçu, Paraná state, Brazil, on border with Argentina and Paraguay. Blood samples were collected perform following serologic tests: immunochromatographic DPP® rapid test, indirect immunoenzymatic assay (ELISA) immunofluorescence (IFA). In 2012, 285 analyzed border, 2013, serum 396 Paraguay collected. Using ELISA for screening IFA confirmatory results showed...
The aim of this study was to confirm the emergence canine visceral leishmaniasis among dogs in Foz do Iguaçu. disease diagnosed through isolation and molecular identification Leishmania infantum. In first sample collection stage (2012), three lymph node aspirates 46 buffy coat samples were obtained mostly from that seroreagents for leishmaniasis. second (2013), collected 376 located close Paraguay, Paraná river, center peripheral parts city. DNA six isolates, four sampling (4/49) two...
Abstract Visceral leishmaniosis is one of the most important zoonotic diseases on planet and dogs are main reservoir canine visceral (CVL) in endemic areas. They play an role human infection because disease appears long time after infection, they can move uncontrollably, contributing to disperse parasite. To take decision treat animals or for euthanasia, elimination programme, order reduce parasitic load, it necessary diagnose correctly, having more effective tools. Our group has developed a...
Toxoplasma gondii is a protozoan with worldwide distribution, responsible for causing toxoplasmosis, disease that affects mammals, reptiles, amphibians and birds. The objective of this study was to evaluate T. seroprevalence in dogs cats domiciled cities from West Serrana mesoregions Santa Catarina. A total 338 blood samples, 211 127 were collected submitted the indirect haemagglutination technique (IHT) detection anti-T. antibodies. Epidemiological questionnaire asking information related...
Background: Leptospirosis and brucellosis are zoonosis worldwide distributed that have great economic importance, especially in goats. This study aimed to carry out a cross-sectional determine the prevalence of anti-Leptospira spp. anti-Brucella abortus antibodies epidemiological variables associated infection by these ethiological agents goats.Materials, Methods & Results: Serum samples were collected from 1055 goats 95 properties 18 regional centers Paraná State April August 2010....
