Abstract Renicolids are parasites that inhabit the renal tubules and ureters of molluscivorous piscivorous birds. Puffinus puffinus is a migratory seabird was identified as definitive host Renicola spp. Studies focusing on renicolid species resulting lesions valuable for their association with causes stranding in seabirds. The aim this study to identify trematodes evaluate histological findings two P. stranded coast Paraná state, Brazil. were evaluated by histologic, ultrastructural...
The aim of this study were to detect antibodies anti-Leishmania spp. and anti-Trypanosoma cruzi in two different populations domestic cats (Felis catus domesticus) from North Paraná referred for surgical castration determine which characteristics the animals studied may be associated with seropositivity. Serum samples 679 analyzed using enzyme-linked immunosorbent assay (ELISA) indirect immunofluorescence antibody test (IFAT) series. Associations between age, sex, race, year care animal...
Abstract Toxoplasmosis is a reportable disease in Brazil. The objective of this study was to investigate toxoplasmosis outbreak at research institution Londrina—PR, reported October 2015; however, the first cases occurred August 2015. Blood samples were collected from 674 persons institution. Samples soil, water (water tank) and food (vegetables) served restaurant. Each participant responded an epidemiological questionnaire. For blood samples, chemiluminescent microparticle immunoassay...
Cattle are an important source of zoonotic species Cryptosporidium for humans. The aim this study was to investigate the presence Cryptosporidium, identify and determine risk factors relating environment, animals management among dairy calves in eight Brazilian states. A total 408 fecal samples from aged 1-60 days were analyzed. An epidemiological questionnaire completed. Sample screening performed using Ziehl-Neelsen technique positive subjected nested PCR. identified by means PCR-RFLP...
Abstract The aim of this study was to determine the occurrence anti-Toxoplasma gondii and anti-Neospora caninum antibodies their associated factors among goats in farms from Paraná state, South Brazil. serological analysis performed by indirect ELISA on 629 goat serum samples collected 32 distributed five mesorregions state. Seropositivity observed 30.7% animals for T. gondii, 6.3% N. caninum, 3.0% both agents. Final multiple regression models showed that use assisted reproduction decreased...
The aim of this review was to present the main anthropogenic threats seabirds, a taxonomic group described as environmental sentinels, and dynamics between parasites hosts their relationship with health marine ecosystem. Coastal environments support various activities, exposing seabirds multiple synergistic changes. These activities are considered negative maintenance several seabird species, such exposure constant aquatic contaminants fishing. In addition, parasitic infectious diseases...
Abstract This study aimed to identify the intestinal parasites of road-killed wild felines in North Central and North, Paraná state, southern Brazil. The animals were monitored by sampling previously established transects. places where run over mapped, identified, gastrointestinal tract was evaluated. feces submitted coproparasitological techniques spontaneous sedimentation, floating hypersaturated NaCl solution centrifugal zinc sulfate. All parasitic structures detected photomicrographed....
Abstract The present study aimed to evaluate a methodology for active surveillance of visceral leishmaniasis by detecting Leishmania DNA in organs wild road-killed animals from November 2016 October 2018 the North Paraná, Brazil. collection points were georeferenced. autopsied and samples bone marrow, lymph node, liver, spleen, ear skin collected. Genomic was extracted subjected PCR amplification spp. 18S, kinetoplastic (kDNA), HSP70, ITS1 genes, sequencing performed. primers used kDNA,...
Feline Morbillivirus (FeMV) was first detected in 2012 domestic cats from Hong Kong and found to be associated with tubulointerstitial nephritis chronic kidney disease. In subsequent studies other countries, FeMV asymptomatic cats. However, it is not clear whether plays a role as pathogen the diseases of cats, epidemiological data are still unknown. To date, have reported presence exclusively This study molecular detection RNA pathological immunohistochemical findings synanthropic marsupial,...
Cetacean morbillivirus (CeMV) was identified as the etiologic agent of several epizootic episodes worldwide. Most these studies are based on unusual mortality events or identification new viral strains. We investigated occurrence CeMV under non-epizootic circumstances at a world heritage in Southern Brazil by combination pathologic, immunohistochemical and molecular assays. From 325 stranded cetaceans, 40 were included. Guiana dolphin (Sotalia guianensis) most frequent species. Interstitial...
This study determined the prevalence of ovine toxoplasmosis and neosporosis risk factors associated with development these diseases in breeding rams from State Rio Grande do Sul (RS), Southern Brazil. Serum samples (n = 1,800) maintained on 705 sheep farms seven mesoregions were evaluated serologically to detect anti-IgG Toxoplasma gondii by indirect ELISA Neospora caninum immunofluorescence assay (IFA). The T. was 33.05% (595/1,800); seropositivity N. 18.44% (332/1,800). Additionally, there...
Abstract The aim of this study was to evaluate the seroprevalence and factors associated with presence anti-Toxoplasma gondii anti-Neospora caninum antibodies in sheep from Paraná state. detection for T. N. performed by homemade commercial indirect ELISA, respectively. Multiple logistic regression analysis used verify seroprevalence. Antibodies anti-T. anti-N. were observed 42.7% 17.6% animals, protective seropositive “some level confinement” (full or semi-extensive confinement) (OR=0.53)...
Caretta caretta, one of the five sea turtle species in Brazil, is currently listed as globally endangered. While health assessments are crucial for monitoring population status, they infrequent and lack systematic implementation. Evaluating condition turtles can occur through examinations both live deceased animals. Carcasses play a pivotal role identifying diseases potential threats impacting species. Therefore, this study presents histopathological findings from 20 dead stranded C. caretta...
As rodovias são essenciais para o desenvolvimento econômico de um país, em contrapartida uma das principais causas fragmentação habitat e perda biodiversidade. A colisão animais silvestres com veículos é a principal causa morte nas estradas, podendo acarretar na alteração dinâmicas populacionais no comportamento espécies. O objetivo deste estudo foi avaliar os atropelamentos mamíferos médio grande porte quatro transectos estradas do norte Paraná, Sul Brasil. Os variaram 193 242 km extensão...

Dogs are considered the main reservoirs of visceral leishmaniasis for humans, which also present a chronic and severe clinical picture when affected. The objective report was to describe canine case diagnosed in Londrina, an indene city, its investigation. A street animal with extensive dermatological lesions, onychogryphosis, mild anemia leukopenia attended at veterinary hospital where positivity reported Leishmania spp. serological tests. Cytology positive bone marrow, PCR parasite culture...

RESUMO A leishmaniose visceral (LV) é uma zoonose de grande impacto em saúde pública. infecção nos gatos tem sido relatada países onde a doença endêmica. Seu papel como reservatório não está satisfatoriamente elucidado, embora transmissão do parasito um felino infectado para vetor tenha reportada por xenodiagnóstico. O objetivo trabalho foi avaliar presença anticorpos anti-Leishmania spp. animais da espécie felina área endêmica LV (Bauru-SP), meio dos testes sorológicos reação...
Trichinella spp. are zoonotic parasites that widely distributed in warm-blooded carnivores and omnivores, including humans. Until the present moment, Brazil has been considered by World Animal Health Organization free from domestic cycle of trichinellosis, whereas parasite's sylvatic status infection limited zones. However, neighboring countries such as Argentina have reports parasite larvae wild fauna. The study aimed to determine occurrence road-killed animals Paraná, Brazil. Biological...
