Abstract:This study aimed to identify the intestinal parasites of road-killed wild felines in the North Central and North, Paraná state, southern Brazil. The animals were monitored by sampling previously established transects. The places where the felines were run over were mapped, the animals were identified, and the gastrointestinal tract was evaluated. The feces were submitted to coproparasitological techniques of spontaneous sedimentation, floating in hypersaturated NaCl solution and centrifugal floating in zinc su… Show more
Aelurostrongylus abstrusus is the most important respiratory parasite infecting domestic cats worldwide. Nevertheless, most records and epizootiological data come from Europe, whilst poor and fragmentary information are available for other regions, including the Americas. The present article describes the first description of cat aelurostrongylosis from Amazonia, Brazil. Eighty-one cats, 13 from a shelter and 68 admitted at the Teaching and Research Unit in Veterinary Medicine (UV) at the Federal University of Acre (UFAC), Brazil, were included in the study. For all cats, three faecal samples from consecutive defecations were examined using the Baermann’s technique. Nematode first stage larvae (L1), retrieved in 2/81 (2.5%) samples, were microscopically identified as A. abstrusus and then subjected to a molecular assay able to identify the three most important species of metastrongyloids infecting felids. This test confirmed the A. abstrusus identity in one sample, while the second scored negative. The cat with confirmed aelurostrongylosis showed radiographic changes, i.e., an interstitial pattern, compatible with the infection. The other cat, which scored positive at the Baermann’s examination, was apparently healthy at the physical examination and showed no thoracic alterations. The occurrence of A. abstrusus in domestic cats from Brazilian Amazon is herein demonstrated for the first time. Clinical, epizootiological and molecular implications are discussed.

Puma yagouaroundi es un felino de amplia distribución en América y poco conocido en su ecología y uso de hábitat, por lo que la presente nota documenta su presencia en sitios periurbanas en Tuxpan, Veracruz, México. Además, el registro de un animal atropellado en una zona cercana demuestra la tolerancia de esta especie a sitios perturbados, así como su susceptibilidad por la mortandad en vías de comunicación, información que puede ser relevante para aplicar programas para su conservación considerando que es una especie amenazada en México.
As rodovias são essenciais para o desenvolvimento econômico de um país, em contrapartida são uma das principais causas de fragmentação de habitat e perda de biodiversidade. A colisão de animais silvestres com veículos é a principal causa de morte nas estradas, podendo acarretar na alteração das dinâmicas populacionais e no comportamento das espécies. O objetivo deste estudo foi avaliar os atropelamentos de mamíferos de médio e grande porte em quatro transectos nas estradas do norte do Paraná, Sul do Brasil. Os transectos variaram de 193 a 242 km de extensão e foram percorridos uma vez por mês, entre novembro de 2016 a outubro de 2018. Após 20.592 km percorridos foram registradas aproximadamente 330 carcaças, sendo que destas, 66 mamíferos de médio e grande porte apresentaram condições de coleta. A Ordem com maior incidência foi Didelphimorphia, seguido por Carnivora e Cingulata. A maior concentração de atropelamentos ocorreu na PR-445, entre os municípios de Mauá da Serra e Tamarana, ambos no estado do Paraná. A mortalidade de espécies ameaçadas de extinção, como L. wiedii, L. guttulus e P. concolor é preocupante. Nossos resultados podem ajudar gestores e órgãos competentes responsáveis pelas estradas a mitigar os atropelamentos, com placas de sinalização de vida silvestre, radares e passagens de fauna em áreas críticas, como o trecho de maior número de registros.
