Abstract
Streptococcus pluranimalium (S. pluranimalium) is unusual streptococcal species, which is rarely identified from humans. Limited cases are reported from this new species; the present study is the first case report from India indicating infection with S. pluranimalium causing empyema.Streptococcus pluranimalium was first isolated in 1999 from a case of bovine mastitis, but has been isolated from a number of other animals like chickens, goats, cats, canaries, sheep, Nile tilapia, a pheasant, and an alpaca.S. pluranimalium can be cultured from various mucosal surfaces (e.g. cervix, vagina, lung, tonsils) and from milk of infected dairy animals.[1,4]S. pluranimalium has some animal reservoirs because the source of this species are milk and other infectious secretions of animals and transmitted to human in the form of zoonosis.[5,6]According to previous experience with rare case reports, vancomycin, aminoglycosides, and cephalosporins are the drugs of choice for S pluranimalium infection
