Fernando de Noronha is an archipelago of 21 islands and islets in the Atlantic Ocean, state Pernambuco, Brazil, which has a varied biodiversity including alien species or sinantropic animals. The objective here was to determine seroprevalence Toxoplasma gondii domestic wild animals from archipelago, Brazil. Between July 2007 May 2010, blood samples were collected 764 (533 231 animals). Sera tested by indirect fluorescence antibody test (IFAT) modified agglutination (MAT), both. Antibodies T....
ABSTRACT Dogs and cats are frequently affected by gastrointestinal parasites of medical veterinary concern. The correct diagnosis is pivotal to the treatment outcome, reducing risk environmental contamination spreading these pathogens. aim this study was determine prevalence domiciled dogs in an urban area Northeastern Brazil, as well discuss findings from a “One Health” perspective. Fecal samples (n = 231) 126) 105) were obtained directly environment after spontaneous defecation,...
Worldwide comparison of Toxoplasma gondii isolates from free-range chickens (Gallus domesticus) has indicated that T. Brazil are phenotypically and genetically different other countries; most strains pathogenic to mice, there is great genetic variability, nonclonal, Type II absent or rare. The prevalence in 50 the island Fernando de Noronha, (this 350 km mainland) was determined. Antibodies were assayed by modified agglutination test (MAT); 42 (84%) had titers 1∶5 2, 1∶10 4, 1∶20 3, 1∶40 6,...
Following the accidental finding of inclusion bodies similar to Anaplasma platys in a stained blood smear from cat, DNA analysis 16S rRNA gene was performed and 100% identity found with different strains A. platys. These data confirm that cats are susceptible parasitism by
Canine heartworm infections were frequently diagnosed in Brazil before the new millennium. After year 2000, frequency of diagnosis showed a sharp decline; however, few years later, evidence indicated that parasite was still present and canine infection rates seemed to be increasing. Therefore, an updated survey prevalence conducted several locations south, southeast, northeast Brazil.Dogs from 15 having previously reported high included according defined criteria, including absence treatment...
Little information is available concerning infection by Leishmania infantum in cats. Therefore, the aim of this study was to perform a serological domestic cats.Serum samples (n=153) obtained from animals living Cities Recife and Petrolina, State Pernambuco, Brazil, were tested ELISA/S7® (Biogene).Anti-L. antibodies detected 3.9% (6/153) All seroreagent Petrolina.These results serve as an important alert, future studies are needed better understand possible role cats epidemiology visceral...
The northeast region of Brazil is endemic for zoonotic visceral leishmaniasis (ZVL). aim this study was to determine the prevalence infection in dogs Petrolina.Blood samples were collected from (n = 600), and bone-marrow biopsy performed animals with positive serological test results that presented clinical signs ZVL. analyses using an enzyme-linked immunosorbent assay (ELISA) (S7(r)Biogene).Of 600 tested, 19% (115/600) anti-L. infantum chagasi antibodies.Our data are important because...
Cryptosporidium and Giardia are protozoans that can infect humans wild domestic animals. Due to the growing importance of diseases caused by protozoan parasites in aquatic species, we aimed evaluate frequency infection spp. sp. marine mammals northern northeastern regions Brazil. We collected 553 fecal samples from 15 species wild-ranging captive All were analyzed Kinyoun technique for identification oocysts. cysts identified means centrifugal-flotation zinc sulfate solution. Subsequently,...

Keeping animals in zoos is important for the preservation of endangered species. However, captive can also be affected by different species parasites. Herein, we aimed to evaluate occurrence gastrointestinal parasites wild and exotic from two state Sergipe, Northeastern Brazil. Fecal samples were obtained spontaneous defecation 287 specimens, grouped into mammals (n = 101), birds 99), reptiles 87). The assessed using techniques, Mini-FLOTAC Ziehl-Neelsen, identify helminths protozoa,...
Heartworm (HTW) infection in cats is associated with persistent pulmonary pathology, even when clinical signs are absent. Treatment options for limited once infected, making prevention an important topic discussion cat owners. In Brazil, tests to detect feline HTW infections unavailable, likely leading underestimation of its impact on the wellbeing cats. The present study investigated seroprevalence antigen living area high canine prevalence and risk factors disease from Rio de Janeiro,...

ResumoOs sinais clínicos das infecções por Ehrlichia canis e Anaplasma platys são similares, o diagnóstico desses patógenos feito esfregaços sanguíneos corados é difícil devido à sensibilidade especificidade.Por outro lado, os diagnósticos moleculares altamente sensíveis específicos, nested-PCRs têm sido otimizadas para preciso em cães.Em um Hospital Veterinário Escola, amostras de sangue total com EDTA foram obtidas 100 cães, feitos busca dos parasitos intracelulares.Para cada amostra, DNA...
INTRODUCTION: The prevalence of infection by Toxoplasma gondii and associated risk factors in pregnant women Tocantins, Northern Brazil were assessed. METHODS: Serological analysis was performed 338 serum samples an oral questionnaire utilized to identify potential factors. RESULTS: Anti-IgG antibodies against T. detected 71% (240/338) the women. Prior contact with cats meat handling found be infection. CONCLUSIONS: A considerable percentage (29%) living Tocantins area remain susceptible...
Gastrointestinal helminths are considered to be the most common parasites affecting cats worldwide. Correct diagnosis of these in animals living urban areas is pivotal, especially considering zoonotic potential some species (e.g. Ancylostoma sp. and Toxocara sp.). In this study, a copromicroscopic survey was conducted using fecal samples (n = 173) from domestic northeastern region Brazil. Samples were examined through FLOTAC technique overall results showed positivity 65.31% (113/173) among...
