Abstract

Mastitis is the main illness in dairy cattle and can cause numerous impacts on milk production process. The disease is characterized by inflammation of the mammary gland in which the infectious agent invades the udder and multiplies. The malfunction and inadequate management of the milking system, lack of hygiene and cleanliness of the premises and equipment are the main factors that favor the occurrence of mastitis. Moreover, the prolonged use of antibiotics can also be an aggravating factor if not performed an adequate disinfection at the time of application of the product. The agents involved in cases of bovine mastitis can be bacteria, fungal (filamentous and yeasts), algae and virus, being that bacteria are the most frequently isolated agents. In the case of bovine mastitis fungal, filamentous fungal are isolated sporadically while yeasts are most frequently isolated. Although bacteria are the agents most commonly found, several sporadic cases of fungal mastitis have been reported. Thus, the aim of this study is to describe the characteristics of fungal mastitis, aiming to provide a greater understanding of the disease and possible prevention and treatment. For this, will be achieved the morphophysiological and molecular identification of the agents isolated from milk samples from mastitis case and, subsequently, analysis for evaluation of the antifungal sensivity profile and capacity of the biofilm production species found, being that the ability to produce biofilm is an important virulence factor that can aggravate the infection and to hamper the treatment of the disease.
