More recent studies on the in vitro susceptibilities of Bacillus spp have been reported (14, 28, 29, 43). Â, A microbiological study of 89 strains of Bacillus spp isolated from clinical blood cultures was performed (43). Intravitreal administration is favored and a combination of 200-400 µg of gentamicin and 450 µg of clindamycin is recommended (17). 41. Patients require extensive surgical debridement and amputation in some cases in addition to intravenous vancomycin with or without gentamicin. B. cereus has also been recovered from patients with severe soft tissue infections after close range gun shot wounds inflicted through clothing (23). 0000048220 00000 n Bacillus atrophaeus is a species of black-pigmented bacteria.

In this series, majority of patients with Bacillusendocarditis were treated with clindamycin. Â, Intravascular devices are the common source of positive blood cultures for Bacillus species. Usually infections have an indolent course and the institution of antimicrobial therapy can await specific sensitivity results. The genus Bacillus includes a great diversity of industrially important strains, including Bacillus atrophaeus (formerly Bacillus subtilis var.
