Distribution of contagious and environmental mastitis agents isolated from milk samples collected from clinically health buffalo cows between brazilian dry and rainy seasons of the year

The present study was performed to evaluate the microbiological characteristics of clinically health quarters submitted to milking and also to observe the distribution of contagious and environmental agents between brazilian dry and rainy seasons of the year. During nine months 734 quarters from 37 buffalo cows were submitted monthly to udder inspection, palpation and strip cup test before milking. 734 asseptic milk samples were inoculated in 10% ovine blood agar and in MacConkey agar media, then incubated for 72 hours at 37 C. Among the 580 isolated microrganisms, 182 (31,38%) were recovered from samples collected during the rainy season and 398 (68,62%) from the dry season. In the rainy period the most prevalent agents were: bacteria from the genus Corynebacterium sp (53,30%), Staphylococcus sp (19,78%) and Rhodococcus equi (13,74%). In the dry period, the commonest ones were: Corynebacterium sp (44,97%), Staphylococcus sp (18,84%) and Micrococcus sp (9,55%). The results demonstrated that the methods used to select health quarters in brazilian dairy buffalo farms allow the transmission of contagious bacteria during both seasons of the year, maintaining agents known to cause mainly subclinical inflammatory reactions that compromise cronically the physiology and production of the mammary gland.

Rodococose equina: uma revisão com ênfase na fisiopatogenia e tratamento

The rhodococcosis affects humans and animals. Equine are the most important species for rhodococcosis, which is considered the most debilitating disease in the creation of foals, leading to a mortality rates greater than 50% in this category. The disease is caused by Rhodococcus equi, a bacteria considered as a soil-born opportunistic microorganism, intracellular and ubiquitous. The disease in horses is manifested mainly in the form of pyogranulomatous pneumonia and less often in the form of enteric disorders and / or joint disorders. Transmission occurs mainly by ingestion of contaminated food and water, and inhalation in contaminated environment. The organism has mechanisms of evasion of the immune system, maintain viable in inside phagocytic cells, and induces piogranulomatous infections, leading to lesions of difficult treatment using conventional antimicrobials. Lipophilic drugs with good intracellular activity are required to successful treatment. The conventional treatment for foals is based on the combination of erythromycin and rifampin. However, there is a growing concern about the emergence of resistant strains, which makes increasingly studies on the development of alternative antimicrobials for therapy
