In conclusion, a licensed strain of S. choleraesuis has a potential as an RNAi delivery system. This strain is very safe for swine, relatively inexpensive to manufacture and well suited for large-scale administration. However, it remains unclear the attenuated Salmonella how to deliver siRNA in vivo. Future studies relevant to cytokine and distribution of siRNA are necessary to examine this issue in more detail. Community acquired methicillin-resistant Staphylococcus aureus pneumonia leading to rhabdomyolysis: a case report Community-acquired methicillin resistant Staphylococcus aureus (CA-MRSA) is considered an underreported entity in India. In this case report, the authors describe a thirty-five year old immunocompetent male presenting with severe respiratory distress requiring intubation. On further work up, a CT thorax showed features consistent with necrotizing pneumonia. The morphology and sensitivity pattern of the organism found in the bronchoalveolar lavage fluid and blood culture were consistent with MRSA. The patient's stay in the hospital was complicated by acute renal failure due to rhabdomyolysis with CPK levels of 9995 U/L. The patient was started on dialysis and improved there after. This case brings to light that CA-MRSA is becoming a problem in developing nations where antibiotics are frequently used empirically with little laboratory guidance. It also is a rare reporting of rhabdomyolysis due to CA-MRSA. CA-MRSA commonly causes skin and soft tissue infections. In the current case report, we describe community acquired pneumonia due to MRSA which is until now infrequently seen. Further, this patient's clinical course was complicated by rhabdomyolysis which is even more uncommon.
