Abstract
A 43 year old male patient came to the emergency department with complaints of severe breathlessness and pedal edema with on & off fever since 15 days. The patient also gave history of sexual exposures with multiple partners. ECHO revealed moderate LV dysfunction, severe aortic regurgitation (AR), trivial mitral regurgitation (MR) with mild pulmonary edema. The patient was diagnosed as a case of severe Aortic regurgitation with atrial fibrillation. The patient was found sero-positive for HIV and Syphilis. His blood cultures obtained prior to initiation of antibiotics showed growth of small 0.5-1mm in diameter, β- hemolytic colonies on blood agar The isolate was identified to be Streptococcus pseudoporcinous by VITEK2 Compact system and was sensitive to vancomycin, linezolid, penicillin, cotrimoxazole and ciprofloxacin. Streptococcus pseudoporcinus is usually found as colonizer of female genital tract has been rarely associated with bacteremia. In the present report the patient possibly has acquired the infection from female genital tract because of his abnormal sexual behaviour. Association of Streptococcus pseudoporcinus with increased numbers of sexual partners and sexually transmitted infections suggests that further studies of this organism are warranted.
