Mastite Bovina: Uma Revisão

Abstract

The mastite, inflammation process of mammary gland, characterized by a decrease in production and changes in milk composition, is considered the disease of major impact for dairy cattle in Brazil. Normally, this disease is resultant of the action of infectious agents, and may be involved different species of virus, fungi, and mainly, bacteria. It is important to remember, that the mastite, of any form and effect, reduces milk production and, in severe cases, may occur loss of one or more teats. Thus, the control of bovine mastite is important for the milk production of high quality. The aim of study is develop a study about this pathology that affects the dairy cattle and their effects in production and quality milk, and consequently, farmers, dairy industry and their products.

Resistance Profile of Bovine Mastitis Isolates, Presence of the mecA Gene and Identification of ESBL Producing Strains from Small Rural Dairy Properties

“…In the municipality of Boa Esperança and Tapejara, Non- aureus CoPS, 12.85% and 6.45%, respectively, and Staphylococcus aureus , 22.85% and 4.53%, were isolated in the municipality of Juranda for Non- aureus CoPS 5.97% and Staphylococcus aureus 2.98% was isolated less frequently. These agents are associated with subclinical mastitis of contagious origin—that is, they are easily disseminated by the herd, they are passed unnoticed because they do not present evident clinical signs and in some cases a decrease in milk production [ 8 , 11 ].…”

“…Other widely used antibiotics are amoxicillin, erythromycin, gentamicin and penicillin. Animals that are vaccinated against strains of Escherichia coli have a better cure rate for treatments with antibiotics [ 4 , 8 ].…”

“…The clinical form causes visible changes in the udder, evident signs of inflammation, associated with changes in milk composition [ 7 ]. The subclinical is characterized by an asymptomatic infection or only a decrease in milk production can be observed [ 8 ]. In the chronic form, there is fibrosis—with an absence of signs of the inflammatory process and changes in the milk, the result of a persistent process—which may form fistulas in the affected mammary gland [ 9 ].…”

“…A mastite é uma doença que causa muitos prejuízos econômicos e é a enfermidade mais distribuída nos rebanhos leiteiros (SANTOS et al, 2017;MASSOTE et al, 2019). Essa enfermidade ocorre através da entrada do agente no canal do teto e a gravidade dos sinais clínicos irá depender da capacidade do microrganismo de colonizar e multiplicar-se no úbere, da virulência da cepa e da resposta imune do hospedeiro.…”
