Geoepidemiology, seroprevalence and factors associated with Toxoplasma gondii infection in domicilied cats from Paraíba (Brazil).

Toxoplasma gondii is a parasite responsible for toxoplasmosis, an emerging and often neglected zoonosis in South America, particularly Brazil. Felines, the only definitive hosts, excrete oocysts in their feces, potentially infecting all homeotherms. Domestic cats are primarily responsible for contaminating human environments with these oocysts. Monitoring their populations is therefore essential to ensure proper toxoplasmosis prophylaxis. The aim of this study was to estimate the prevalence of T. gondii and exposure factors in a population of owner cats in the city of João Pessoa, Paraíba, Brazil. A total of 267 blood samples were collected from domestic cats aged between 1 and 15 years and tested with an immunofluorescence antibody test. The seroprevalence of antibodies against T. gondii was only 17.22% (46/267 individuals). This result therefore suggests a low contribution of domestic cats to T. gondii contamination of the urban environment. The cats' age and living environment were identified as risk factors for cat exposure to T. gondii.

Title: Géoépidémiologie, séroprévalence et facteurs associés à l'infection à Toxoplasma gondii chez les chats domiciliés à Paraíba (Brésil). Abstract: Toxoplasma gondii est le parasite responsable de la toxoplasmose, une zoonose émergente et souvent négligée en Amérique du Sud, notamment au Brésil. Les félins, seuls hôtes définitifs, excrètent des oocystes dans leurs selles, infectant potentiellement tous les homéothermes. Les chats domestiques sont les premiers responsables de la contamination des environnements humains avec ces oocystes. La surveillance de leurs populations est donc essentielle pour garantir une prophylaxie adéquate contre la toxoplasmose. Le but de cette étude était d'estimer la prévalence de T. gondii et les facteurs d'exposition dans une population de chats domestiques de la ville de João Pessoa, Paraíba, Brésil. Au total, 267 échantillons de sang ont été prélevés sur des chats domestiques âgés de 1 à 15 ans et testés avec un test d'immunofluorescence des anticorps. La séroprévalence des anticorps contre T. gondii n'était que de 17,22 % (46/267 individus). Ce résultat suggère donc une faible contribution des chats domestiques à la contamination du milieu urbain par T. gondii. L'âge et le milieu de vie des chats ont été identifiés comme facteurs de risque d'exposition du chat à T. gondii.

Anti-Sporothrix Antibody Detection in Domestic Cats as an Indicator of a Possible New Occurrence Area for Sporotrichosis in North Brazil.

Feline sporotrichosis has emerged as an important public health issue in some countries, especially Brazil. Currently, zoonotic transmission of Sporothrix brasiliensis by domestic cats is the major sporotrichosis spread form throughout this country. Sporotrichosis in Brazil is a good model for the One Health concept application, which connects the environment, human and animal health. Under this thinking, the aim of this study was to investigate the seroprevalence of sporotrichosis in cats from Rolim de Moura, Rondônia, Brazil, using antibody detection by an ELISA test previously validated for human diagnosis. For the standardization of this test, 30 serum samples from cats with proven sporotrichosis and 11 sera from healthy cats were used. The assay showed 87% sensitivity and 100% specificity for the diagnosis of feline sporotrichosis. After the standardization, 202 serum samples from distinct cats from Rolim de Moura were evaluated. The test was positive in 63 (31.19%) cats from the studied area. A multivariate analysis revealed that living far from forest or agricultural areas as well as pure breed animals had higher odds ratios (3.157 and 2.281, respectively) for the presence of detectable levels of anti-Sporothrix antibodies. These results show the applicability of this assay in the detection of anti-Sporothrix antibodies in feline serum samples and point to a putative new occurrence area of urban sporotrichosis dispersing to the North region of Brazil.

Avaliação da percepção dos estudantes de odontologia sobre emergências médicas / Evaluación de la percepción de los estudiantes de odontología sobre emergencias médicas / Evaluation of Dental Students' Perception about Medical Emergencies

RESUMO Introdução: Diversas situações no consultório odontológico podem gerar quadros de emergência. A administração de anestésicos locais, o atendimento odontológico aos pacientes com comprometimento sistêmico, ansiedade e medo são muitas vezes as causas mais comuns. Objetivo: O objetivo deste estudo foi avaliar o nível de percepção dos alunos de Odontologia frente às principais emergências odontológicas. Métodos: Tratou-se de um estudo transversal e descritivo com abordagem quantitativa dos dados por meio dos questionários. Foram entrevistados 138 alunos cursando do 5º ao 10º período de odontologia da Universidade Federal de Campina Grande, na cidade de Patos, Paraíba. Resultados: Foi observado que 86,2 porcento do total de entrevistados responderam saber a diferença entre urgência e emergência; 52,2 porcento dos alunos confirmaram receber ou terem recebido instruções extracurriculares sobre o assunto; 59,4 porcento responderam que o aprendizado fornecido na graduação sobre este tema não está sendo suficiente. Cerca de 17,4 porcento destes alunos responderam saber realizar as manobras de Reanimação Cardiopulmonar, 11,6 porcento dos entrevistados relataram que se sentiam preparados para lidar com uma situação de emergência e 81,9 porcento dos alunos pretendem buscar uma formação complementar durante ou após a graduação. Conclusão: Verificou-se que os alunos de graduação em odontologia apresentaram um baixo nível de percepção sobre as emergências médicas no consultório odontológico(AU)

ABSTRACT Introduction: Several situations in the dental office may cause emergency cases. Administration of local anesthetics, dental care to patients with systemic deterioration, anxiety and fear are often the most common causes. Objective: To evaluate the dental level of perception of dental students facing the main dental emergencies. Methods: This was a cross-sectional and descriptive study of the data through questionnaires. We interviewed 138 students from the 5th to the 10th period of Dental Medicine at the Federal University of Campina Grande, in the city of Patos, Paraíba. Results: We observed that 86.2 percent of the interviewed students knew the difference between urgency and emergency; 52.2 percent of the students confirmed receiving or having received extracurricular instructions about the topic; 59.4 percent answered that the learning provided about this topic after graduation is not being sufficient. About 17.4 percent of these students responded positively to knowing how to perform cardiopulmonary resuscitation maneuvers; 11.6 percent of those interviewed felt themselves prepared to deal with an emergency situation, while 81.9 percent of the students interviewed intended to seek complementary training during or after graduation. Conclusion: Dental students were found to have a low level of perception about medical emergencies in the dental office(AU)
