Pesquisa de Yersinia pestis em roedores e outros pequenos mamíferos nos focos pestosos do Nordeste do Brasil no período 1966 a 1982

Abstract

de et al. Pesquisa de Yersinia pestis em roedores e outros pequenos mamíferos nos focos pestosos do Nordeste do Brasil no período 1966 a 1982. Rev. Saúde públ., S. Paulo, 21:265-7, 1987.RESUMO: Foi feita análise da metodologia empregada e dos resultados alcançados em pesquisa de Yersinia pestis, em material de 24.703 roedores e outros pequenos mamíferos oriundos dos focos pestosos do Nordeste do Brasil, no período de 1966 a 1982. Concluiu-se ser necessário haver maior rapidez na realização dos exames para que os dados obtidos sejam convenientemente aplicados nas atividades de vigilância e controle da peste.

Ongoing quiescence in the Borborema Plateau Plague focus (Paraiba, Brazil)

“…The last outbreak in Brazil occurred over 30 years ago (Almeida et al 1989), the last human case was registered over a decade ago (Tavares et al 2012), and the last large-scale investigation on the Northeastern foci registered only 0.25% prevalence (one individual of Monodelphis domestica out of 393 individuals trapped), and antibody low titer (Costa et al 2017). Even during activity periods, the prevalence is historically very low (0.1-4.5%) (Almeida et al 1987(Almeida et al , 1995. It is possible that the prevalence registered by the literature (PCP and research papers) in Brazil could be underrepresenting the real dimension of the infection, as it was focused on synanthropic rodents, and did not survey the fauna of the native vegetation fragments, possibly neglecting a fraction of the reservoir system (Zeppelini et al 2016).…”

“…As an infectious disease with high mortality and morbidity, it is imperative to maintain constant surveillance of the foci since the cycle can undergo quiescence periods where the infection lies undetectable (Haule et al 2013). In Brazil, the plague surveillance program was firstly based on rodent trapping and collection of fleas for bacterial detection, serosurveys on rodent domestic carnivores (dogs and cats) populations (Almeida et al 1981(Almeida et al , 1987(Almeida et al , 1995. Since 2007, the surveillance was restricted solely to serosurveys in domestic carnivores as sentinels of infection (Tavares et al 2012).…”

“…These studies also examined the current state of the foci under effects of anthropogenic impacts and climate change, and performed a taxonomical update of the reservoir species (Costa et al 2017, Bonvicino et al 2015. Nonetheless, the studies did not sample the Borborema Plateau Focus, especially its portion in the state of Paraíba where the last Brazilian plague outbreak was reported (1986( -1987( ) (Almeida et al 1989).…”

Didelphis spp. opossums and their parasites in the Americas: A One Health perspective

“…Fleas are also known as vectors of the deadly bacteria Y. pestis (Pechous et al 2016). Up to date, this bacterium has been detected through serological and bacterial culture in D. albiventris in Brazil (Almeida et al 1987;Almeida et al 1995). Indeed, considering the infestation of the main vector of this bacterium (i.e., X. cheopis) on D. aurita (Bezerra-Santos et al 2020b), it is worth to further investigate the role of these animals as reservoir of this pathogen.…”

Memórias sobre tempos de peste

“…Aqui, neste item, peste será usado como definição de Yersinia pestis, que poderia se apresentar sob as formas pulmonar, septicêmica e bubônica: mbáva, tasy ai (T:329, 391 V:281, 319) peste, mortandad, acabamiento. Trata-se de uma zoonose transmitia por dois vetores: pulgas e roedores da fauna nativa e da introduzida pelos europeus (Almeida et al 1987), altamente contagiosa e letal. Contudo, Montoya não foi mais específico para descrevê-la, deixando nas entrelinhas a definição de 1611 (TC 1:587): peste, enfermedad contagiosa, que comunmente se engendra del aire corrompido, del latín pestis.…”
