Five specimens of Plagioscion squamosissimus from Xingu River and ten specimens of Pellona castelnaeana from Mosqueiro Island, both in the State of Pará, Brazil, were examined to investigate the presence of anisakid nematodes, due to their zoonotic potential. Their parasitism indices and sites of infection were also determined. This is the first record of Anisakidae parasitizing Pellona castelnaeana. Four-hundred and eighty-four third-stage larvae (L3) of Anisakidae were found, of which 42 were found in P. squamosissimus and 442 in P. castelnaeana. The parasitism indices of the anisakid collected from the P. squamosissimus comprised prevalence (P) of 100%, mean infection intensity (MI) of 8.4, range of infection (RI) of 1-13, mean abundance (MA) of 8.4,... |

ABSTRACT In this study, we described the antifungal activity of three Brazilian propolis extracts: brown, green and from jataí bees against Sporothrix brasiliensis. The extracts were obtained from ethanolic extraction and their chemical composition was determined by high-performance liquid chromatography coupled to mass spectrometry. The cellular toxicity was measured in MDBK (Madin-Darby Bovine Kidney) cells and quantified by the MTT assay (3- (4,5 dimethylthiazol-2yl -2,5-diphenyl-2H bromine tetrazolato). For antifungal activity, the minimum inhibitory concentration (MIC) and minimum fungicidal concentration (MFC) were determined by broth microdilution. The results showed that cell toxicity was not observed at lower concentrations (0.097 to 0.39μg/ml)... |

In the present study we aimed to establish the seroprevalence of T. gondii and N. caninum in stray and domiciled cats from the municipality of Patos, Paraíba state, Brazil. Blood samples were collected from 201 animals: 132 domiciled cats and 69 stray cats. An epidemiological questionnaire was conducted with all cat owners. Indirect immunofluorescent antibody test (IFAT) was performed at cut-offs of 1:16 and 1:50 for T. gondii and N. caninum, respectively. Overall prevalence of seroreagent cats for T. gondii was 43.8%. We found a prevalence of 47.7% in domiciled cats and 36.2% in stray cats. Antibody titers ranged from 1:16 (cut-off) to 1:8192; 1:128 was the most frequent titer. No statistical difference was observed between domiciled cats and stray cats.... |

Hepatitis E virus (HEV) is highly disseminated among swine herds worldwide. HEV is also a threat to public health, since particularly genotypes 3 and 4 may cause acute hepatitis in human beings. No previous studies were done on the occurrence of HEV in environmental samples in Rio Grande do Sul, Brazil. In the present study, reverse transcriptase-polymerase chain reaction (RT-PCR) was employed to detect the presence of HEV in swine feces and in effluents from slurry lagoons in farms located in the municipality of Teutônia, inside the area of swine husbandry in the state. Pooled fecal samples from the floor of pig barns from 9 wean-to-finish farms and liquid manure samples were collected from the slurry lagoons from 8 of these farms. From the pooled fecal... |

ABSTRACT The aim of this study was to diagnose dermatophytosis in pets and investigate the presence of dermatophytes in their home environment. Samples from hair coat were collected from 70 pets: 47 dogs, 19 cats, three guinea pigs and one rabbit. After mycological culture, 188 samples were collected from the household environments in 26 homes: 78 from places were of predominantly used by the tutors, 66 from places used by the animals, 44 from flooring, and 24 samples from contactees. Samples were seeded on Mycosel agar, incubated at 25°C, and the colonies were identified by their macro-and-microscopic characteristics. Dermatophytes were found in 37.1% of the samples originating from the sick animals. Microsporum canis was the most prevalent species,... |

OBJECTIVE: In order to evaluate the potential zoonotic transmission of Giardia duodenalis, isolates from humans and dogs in the Northwestern region of the São Paulo State, Brazil were characterized based on the β-giardin gene. METHODS: The samples were analyzed by sequencing of the Nested-PCR products. RESULTS: The A1 and A2 subgenotypes were detected in human and dogs. Cysts of assemblage B, C and D have not been found in any isolates studied. CONCLUSIONS: These results are consistent with the view that giardiasis in the largest endemic region of the Brazil should not be seen as a single entity. |

Hepatitis E virus (HEV) is classified within the family Hepeviridae, genus Hepevirus. HEV genotype 3 (Gt3) infections are endemic in pigs in Western Europe and in North and South America and cause zoonotic infections in humans. Several serological assays to detect HEV antibodies in pigs have been developed, at first mainly based on HEV genotype 1 (Gt1) antigens. To develop a sensitive HEV Gt3 ELISA, a recombinant baculovirus expression product of HEV Gt3 open reading frame-2 was produced and coated onto polystyrene ELISA plates. After incubation of porcine sera, bound HEV antibodies were detected with anti-porcine anti-IgG and anti-IgM conjugates. For primary estimation of sensitivity and specificity of the assay, sets of sera were used from pigs... |

Abstract Borreliosis caused by Borrelia burgdorferi sensu lato is a cosmopolitan zoonosis studied worldwide; it is called Lyme disease in many countries of the Northern Hemisphere and Lyme-like or Baggio-Yoshinari Syndrome in Brazil. However, despite the increasing number of suspect cases, this disease is still neglected in Brazil by the medical and veterinary communities. Brazilian Lyme-like borreliosis likely involves capybaras as reservoirs and Amblyomma and Rhipicephalus ticks as vectors. Thus, domestic animals can serve as key carriers in pathogen dissemination. This zoonosis has been little studied in horses in Brazil. The first survey was performed in the state of Rio de Janeiro, and this Brazilian Borreliosis exhibits many differences from the... |

We have studied the prevalence of Trichinella spiralis, Leptospira spp. and Salmonella spp. in rats and opossums that inhabit poultry farms of Exaltación de la Cruz, Buenos Aires, Argentina, to determine the potential sanitary risk for humans that are in contact with these animals. The study was carried out on 48 poultry farms between spring 1999 and winter 2001. The study of opossums began in winter 2000. During the study period we captured 152 Rattus norvegicus, 3 Rattus rattus, 16 Didelphis albiventris and 1 Lutreolina crassicaudata. We have registered the presence of rats and opossums in 70% and 27% of the studied farms, respectively. The percentage of farms with rats was independent of the presence or absence of pigs. We did not detect the presence of... |

ABSTRACT: Vesicular stomatitis virus (VSV) is the agent of a vesicular disease that affects many animal species and may be clinically confounded with foot-and-mouth disease in ruminant and swine. Horses are especially susceptible to VSV and may serve as sentinels for virus circulation. The present study investigated the presence of neutralizing antibodies against VSV Indiana III (VSIV-3) in serum samples of 3,626 horses from six states in three Brazilian regions: Southern (RS, n = 1,011), Midwest (GO/DF, n = 1,767) and Northeast (PB, PE, RN and CE, n = 848) collected between 2013 and 2014. Neutralizing antibodies against VSIV-3 (titers ≥40) were detected in 641 samples (positivity of 17.7%; CI95%:16.5-19.0%), being 317 samples from CE (87.3%; CI95%:... |

ABSTRACT: This study aimed to characterize ocular diseases in dogs naturally affected by visceral leishmaniasis in Teresina, Piauí State, Brazil. The diagnosis was made using parasitological exams of the bone-marrow and lymph-node samples. The main ophthalmological findings were uveitis, conjunctivitis, blepharitis, keratitis, and keratoconjunctivitis sicca. Normocytic normochromic anemia was the main hematological finding, followed by thrombocytopenia. Plasma proteins were also considered, and hyperproteinemia, hypergammaglobulinemia, and hypoalbuminemia were observed. Ocular histopathological examination revealed mild inflammation involving lymphocytes, monocytes, and macrophages. Results indicate the need to perform a differential diagnosis to rule out... |
