Seroprevalence and spatial distribution dynamics of Yersinia pestis antibodies in dogs and cats from plague foci in the State of Ceará, Northeastern Brazil

Abstract: Introduction:In Brazil, the plague is established in several foci located mainly in the northeastern part of the country, where it alternates between active and quiescent periods. These foci in the State of Ceará have high epidemiological importance. In addition to other plague detection activities, plague areas can be monitored through serological surveys of dogs and cats (domestic carnivores), which, following feeding on plague-infected rodents, can develop mild to severe forms of the disease and produce lon… Show more

“…In the Agreste mesoregion, the highest number of positive cases was registered in the municipalities of Bom Conselho (20), Cachoeirinha (13) and Panelas (11) and other 31 municipalities registered one to 10 plague-positive cases. These municipalities are located in the Planalto da Borborema, another focal plague area involved in the 1961-1976 epidemics in the state of Pernambuco.…”

“…The activities of the infection in these foci are independent in time and space [9]; after several successive outbreaks of varied sizes until the decade of 1980, cases in Brazil decreased and the last confirmed human case was in 2005 [12,13]. Despite its current quiescent state, we must remain vigilant and maintain rigorous epidemiological surveillance.…”

“…Therefore, serological testing is of most importance for plague diagnosis and surveillance activities, as it can detect not only active infections in humans and other hosts, but also retrospectively identify individuals exposed to the bacteria [9,10]. In this scenario, serological surveillance must consider a wide variety of mammals to be tested, such as rodents and other small mammals, domestic (dogs and cats) and wild carnivores that pray on rodents [5,12,21,22,24].…”

“…Esses focos são remanescentes da introdução da infecção pelo porto de Santos, SP durante a última pandemia em 1899 (figura 1). Até a década de 1980, ocorriam surtos a cada 5 -10 anos, que eram entremeados por períodos variáveis de quiescência 4 ; porém, a maioria das áreas focais não apresenta notificações há mais de 50 anos, apesar da detecção da circulação da Yersinia pestis, o seu agente etiológico, em animais sentinela 5,6 . Desde 2005, casos suspeitos isolados são notificados, mas todos eles têm sido, sistematicamente, descartados laboratorialmente 5,6 .…”
