Introduction: Although occupational exposure to has been studied previously, the zoonotic risk in wildlife environments remains unclear and has yet to be fully established.

Methods: Accordingly, the present study aimed to serologically assess professionals with daily contact with free-living and captive wildlife in Paraná State, Brazil, along with the potential associated risk factors for exposure.

Results: Overall, 25 out of 309 (8.

Purpose: Animal hoarding has been associated with unhealthy human, animal and environmental conditions that predispose such individuals to serious life-threatening risks such as arson, malnutrition, cruelty and zoonosis. The study aimed to evaluate the presence of anti-Toxocara spp. antibodies among individuals with animal hoarding disorder in Curitiba, Brazil.

Animal hoarding disorder (AHD) is classified as a psychiatric obsessive-compulsive condition characterized by animal accumulation and often accompanied by unsanitary conditions and animal cruelty. Although AHD may increase pathogen transmission and spread, particularly for zoonotic diseases, human and dog exposure in such cases has yet to be fully established. Accordingly, this study aimed to assess Brucella canis in 19 individuals with AHD (11 households) and their 264 dogs (21 households) in Curitiba, the eighth largest city in Brazil, with approximately 1.

The present study describes from the holistic One Health perspective a case report of dioctophimosis in a community dog (defined as stray dogs managed by the local community) residing in a park in the city of Curitiba-PR, considering the multispecies collectives directly affected by the dynamics of this dangerous zoonosis. The work underlines the importance of the community dog program of the Rede de Proteção Animal, demonstrating the health barrier function of these dogs. Despite being a cosmopolitan zoonosis, dioctophimosis is of particular importance in regions of the developing world, including Latin America, because of large populations of stray animals and social inequalities.

Despite being an important public health issue, particularly due to rabies, dog bites and associated risk factors have rarely been assessed by health services from a One Health perspective. Accordingly, the present study aimed to assess dog biting and associated demographic and socioeconomic risk factors in Curitiba, the eighth-largest Brazilian city with approximately 1.87 million people, based on the post-exposure prophylaxis (PEP) rabies reports between January/2010 and December/2015.

Article Synopsis
  • The study investigates hoarding disorder (HD), specifically animal hoarding disorder (AHD), focusing on its potential environmental health risks associated with zoonotic diseases.
  • It assessed the presence of anti-Leptospira spp. antibodies in 19 individuals with AHD and 264 dogs in Southern Brazil, finding no human seropositivity but a 6.1% seropositivity rate among dogs.
  • The study highlights a possible lower prevalence of leptospirosis in hoarded dogs compared to other populations and emphasizes the need for public health awareness regarding this risk in AHD households.

Despite vulnerability and unsanitary conditions of animal hoarding may predispose environmental contamination and spread of vectors and pathogens, no study to date has focused on their impact on public health and zoonotic diseases. Accordingly, this study aimed to assess the seroprevalence of anti-Toxoplasma gondii antibodies and associated factors in individuals with animal hoarding disorder (AHD) and their dogs in Curitiba, Southern Brazil. Blood samples were obtained from 264 dogs (21 households) and 19 individuals with AHD (11 households).

Rickettsia spp. bacteria are responsible for tick-borne diseases worldwide, mostly maintained by rickettsial amplifiers capybaras in Brazilian endemic areas. The campus of the University of São Paulo, in southeastern Brazil, is an area endemic for Brazilian spotted fever (BSF), with high density of capybaras and Amblyomma spp.

Seroprevalence of Toxoplasma gondii has been extensively studied in wild boars worldwide due to the emerging risk for human infection through meat consumption. However, this is the first study that reports toxoplasmosis seroprevalence in wild boars, wild boar hunters and their hunting dogs. The aim of the present study was to evaluate the seroprevalence of anti-T.

Article Synopsis
  • Leptospirosis is a neglected disease linked to poor infrastructure and socioeconomic issues in urban slums, primarily spread through rat urine, highlighting the need for local prevention strategies.
  • The study in Curitiba, Brazil, classified urban neighborhoods based on twelve risk factors to identify areas potentially at higher risk for human leptospirosis, while also assessing Leptospira spp. in rats for a better understanding of transmission.
  • Results showed that while most census sectors (84.8%) were considered low-risk, key risk factors for rodent presence included inadequate water supply and sanitation issues, indicating that local environmental conditions significantly influence disease risk.

Introduction: Leptospirosis is a zoonosis that affects both humans and animals. Dogs may serve as sentinels and indicators of environmental contamination as well as potential carriers for Leptospira. This study aimed to evaluate the seroprevalence and seroincidence of leptospirosis infection in dogs in an urban low-income community in southern Brazil where human leptospirosis is endemic.

Barbary sheep (Ammotragus lervia) have the potential to act as hosts of important infectious diseases, particularly zoonoses. Blood samples from 17 Barbary sheep at the Curitiba zoo were collected to evaluate occurrences of anti-Toxoplasma gondii and anti-Neospora caninum antibodies, tested using the indirect immunofluorescence antibody test (IFAT). Anti-T.

Introduction: After 29 years, rabies was detected in a cat in Curitiba, southern Brazil.

Methods: The fluorescent antibody test (FAT) and mouse inoculation test (MIT) were performed on central nervous system (CNS) samples.

Results: Direct immunofluorescence was negative, but the biological test was positive and rabies virus was characterized as variant 4 (from Tadarida brasiliensis).
