Abstract
Foram avaliados três processos de acondicionamento e transporte de pulgas, objetivando análise bacteriológica para isolamento da Yersinia pestis. As três abordagens testadas foram: pulgas vivas em tubos de ensaio com tiras dobradas de papel de filtro; pulgas em solução salina; macerados de pulgas em meio de Cary-Blair. Os dois últimos métodos foram quase iguais e superiores ao primeiro. Foram analisadas pelas três técnicas, um total de 29.512 "pools" de pulicideos provenientes de focos de peste do Nordeste do Brasil no período de 1966 a 1982. Deste total, 236 (0,80%) dos "pools" foram positivos por cultura e/ou inoculação em animais sensíveis.
Three different containment transport processes of fleas were evaluated as an approach to the bacteriologic isolation of Yersinia pestis. The three methods employed were: live fleas in glass tubes containing pieces of wrapped filter paper; dead fleas in saline solution; and maceratedfleas in Cary-Blair culture medium. The two latter methods were almost equal and superior to the first method. A total of 29512 flea pools, from plague foci in Northeast Brazil collected during 1966 to 1982 were evaluated by the three methods. Among these samples, 236 (0.80%) flea pools were positive with regard to bacteriological cultivation and/or infection of susceptible animals.
