FACTORS AFFECTING CURE OF STAPHYLOCOCCUS A UREUS MASTITIS TREATED WITH SYSTEMIC OR INTRAMAMMARY EXTENDED THERAPIES

摘要

The prevalence of Staphylococcus aureus infections can be reduced through the 5-point plan. Proper milking techniques, appropriate treatment of clinical cases, dry cow therapy, post dipping, and culling of chronically infected animals have been used successfully by producers. The segregation of infected animals has shown its efficacy in preventing new infections, however not all producers can handle extra groups (Wilson et al., 1995). During the last years many studies were conducted to determine factors at cow, pathogen, and treatment level that affect the probability of cure of infections caused by Staphylococcus aureus (Barkema et al., 2006). Intramammary infusions or the combination of intramammary and systemic products are commonly used to treat these infections. There is relatively little information on the efficacy of systemic treatments to treat Staphylococcus aureus subclinical infections.
