Prevalência de Mycoplasma agalactiae em caprinos do Município de Santo André na Paraíba

Abstract

Considering that the animal's health is an important factor for it to be in full production and that mycoplasmosis are systemic diseases that drastically affect animal production, nothing is more pertinent than studying the prevalence of pathogens that cause this disease. In this sense, this work aimed to evaluate the prevalence of the Mycoplasma agalactiae pathogen and compare the diagnosis in samples of milk and nasal swab in dairy goats, in rural properties in the municipality of Santo André, in the state of Paraíba. The swab samples were collected in 30 properties in the municipality of Santo André, in each property samples of 10 animals were collected, totaling 300 samples. Quantitative polymerase chain reaction was used to identify animals infected with M. agalactiae. After collecting and analyzing the data, they were tabulated in Excel® spreadsheets and graphs of three variables were plotted, which were: animal sex, animal breed and animal age The number of positive animals for M. agalactiae was of 27.3%, corresponding to 82 positive animals. At least one animal infected with M. agalactiae was identified in 26 of the 30 properties, demonstrating a high prevalence in the properties. In addition, it was also observed that the number of females with a positive test was higher than males. The number of positive lactating goats was also higher (65%) than adult non-lactating goats (35%). With this, it can be concluded that only in four (13.33%) properties there was no positive animal for M. agalactiae, which is alarming when considering that the city under study is the largest producer of goat milk in the state of Paraíba. Therefore, measures must be taken by local breeders, professionals and the municipal government, aiming at a prophylactic control with good practices so that there is a decrease in the prevalence of this disease.
