Incidência de mormo no estado de Alagoas no período de 2020 a 2023

Abstract

Glanders, also known as donkey phlegm, is a highly infectious disease for horses. It is caused by the bacterium Burkholderia mallei, which presents itself as a gram-negative coccus, and can affect, in addition to horses, carnivores, humans and small ruminants. Being an infectious and zoonotic disease, the recommendation is euthanasia. An epidemiological study of outbreaks and positive cases of glanders in Alagoas was carried out from 2020 to 2023, with the aim of verifying the spatial and temporal distribution and analysis of the mesoregions affected by outbreaks. The population under study was made up of horses (86%), mules (14%) and donkeys (0%) that were distributed in some cities in the State. It was found that the Eastern Alagoan mesoregion, during the period studied, was the one with the highest number of outbreaks, followed by the Agreste and Sertão mesoregions. Regarding the distribution in the State, it was confirmed that there is no homogeneity in relation to the incidence of cases over the months, a wide variety of distribution could be seen, with even months with no reported cases. Therefore, it was found that the positive cases investigated occurred mostly in horses, as this is the most susceptible species due to transport, requiring a negative Complement Fixation (FC) test for glanders, which could cause an economic impact on livestock. of horses.
