Parenteral Treatment of Streptococcus agalactiae Mastitis in Kenyan Camels (Camelus dromedarius)

Abstract

Intramammary Streptococcus agalactiae infections in nine camels (Camelus dromedarius) were treated by a three-day course of intramuscular injection with three different antibiotics to assess whether this route of application had any effect on the quarter infection status. A benzylpenicillin procain dihydrostreptomycin-base combination (12 million IU/12 g per day), penethamate hydroiodide (10 million IU per day) and erythromycin (10 mg/kg per day) were used on three groups of three camels, respectively. Penicillin-streptomycin eliminated S. agalactiae from three out of four infected quarters, penethamate hydroiodide had a curative effect on two out of four quarters, while erythromycin did not alter the infection status of any of the three S. agalactiae-infected quarters treated.
