Description
Summary:The hantavirus cardiovascular pulmonary syndrome (HCVPS) and the plague(Yersinia pestis infection) are zoonoses that occur in Brazil, having in commonrodent reservoirs. Therefore their distribution areas may overlap. The prevalence ofhantavirus antibodies in animals caught in the routine activities of the Plague ControlProgram (PCP) in the State of Ceará in the period from 2002 to 2005 was analyzedin the rodent population in the plague areas. The sample consisted of 239 animals:136 Necromys lasiurus, 31 Oligoryzomys nigripes, 33 Oryzomys subflavus, 4Holochilus sciureus, 24 Rattus rattus, 1 Mus musculus, 8, Trichomys apereoides and2 Galea spixii. Two N. lasiurus captured in the Serra da Ibiapaba were positive forhantavirus antibodies, indicating that humans in these areas are at risk of contractinga potentially lethal infection what justifies the implementation of a research programto study systematically the hantaviruses and rodent hosts in this area. A síndrome pulmonar cardiovascular por hantavírus (SPCVH) e a peste (infecção pela Yersinia pestis) são zoonoses que ocorrem no Brasil. As áreas de distribuição dos dois agravos poderão se sobrepor, pois eles compartilham os mesmos roedores reservatórios. Nosso objetivo foi analisar a prevalência de anticorpos contra hantavírus em roedores de áreas focais de peste no estado do Ceará. A amostra foi composta por 239 animais: 136 Necromys lasiurus, 31 Oligoryzomys nigripes, 33 Oryzomys subflavus, 4 Holochilus sciureus, 24 Rattus rattus, 1 Mus musculus, 8 Trichomys apereoides e 2 Galea spixii. Os soros de dois N. lasiurus capturados na serra da Ibiapaba apresentaram anticorpos anti-hantavirus, evidenciando que as populações humanas dessas áreas estão sob risco de contrair uma infecção potencialmente letal, o que requer a estruturação de um programa de pesquisas com o objetivo de estudar sistematicamente a hantavirose.
