A pitiose em equídeos e bovinos no pantanal matogrossense

Abstract

Pythium insidiosum causa doença de pele e ocasionalmente de outros tecidos de mamíferos e aves que vivem em estreito contato com águas contaminadas. Pelas características bioclimáticas e ambientais da região do Pantanal, estima-se que seja uma das áreas com maior prevalência do mundo. Não obstante, certifica-se na literatura compilada poucos estudo enfatizando aspectos epidemiológicos nessa região, sendo esse o principal objetivo dessa pesquisa. As normais climatológicas foram obtidas de duas estações metereológicas de Instituição pública, que abrange a sub-região do estudo, complementados por dados dispostos em outras fontes. Obteve-se validação de 76 casos em equideos e sete bovinos, através do ELISA-teste, PCR, histopatologia e isolamento do agente. A doença apresentou dinâmica sazonal, com picos de incidência emergindo após os maiores índices pluviométricos. Evidenciaram-se também, um número expressivo de enfermidades confundíveis, coinfecções e reinfecções, demonstrando frágil imunidade do hospedeiro equino ao patógeno. Cabe ressaltar ainda, que ferramentas de diagnóstico são pouco utilizadas a campo. Resposta significativa relativa à imunoterapia (Pitium Vac®) no grupo de equideos tratados e aumento do intervalo de reinfecções, indica que o fármaco poderá ser aperfeiçoado, de modo a agregar características profiláticas, além das terapêuticas

The disease caused by Pythium insidiosum affects the skin and occasionally other tissues of mammals and birds which live in close contact with contaminated water. Due to its bio-climatic and environmental characteristics, the Pantanal region is estimated to be one of the areas with higher prevalence of pythiosis in the world. However, few studies have focused on epidemiological aspects this region, the main objective of this work. Climatological normals were obtained from two meteorological stations of a public institution which covers the subregion studied. Data from other sources were also used to complement the study. Seventy six cases of pythiosis in equidae and seven in cattle were confirmed by ELISA-test, PCR, histopathology and isolation of Pythium insidiosum. The disease showed seasonal dynamics with peaks of incidence emerging after the wettest pluviometric gradients. Similar diseases, co infections and reinfections were also realized, suggesting a suppression of equine immune system to Pythium insidiosum. It is worth mention that diagnosis tests tools available are not widely adopted in the field. Significant response on immunotherapy (Pitium Vac®) in equine treated group and increased of the intervals the reinfection, indicating that the drug could be improved by adding prophylactic and therapeutical properties
