Rare co-existence of Salmonella typhi and mycobacteria tuberculosis in a psoas abscess--a case report.

We report a rare case of dual infection in a psoas abscess. Pus from the abscess grew Salmonella typhi and the abscess wall showed epitheloid granulomas giant cells, which we confirmed as tuberculosis by PCR. Such dual infection cases may be missed unless looked for since both these infections are common in our country.

Role of surface swab, core swab and fine needle aspiration in isolating the core bacteria in inflammed tonsils.

The microbial flora of 75 patients with chronic tonsillitis were sudied to identify the commonest organism causing chronic tonsillitis and to compare surface swab, fine needle aspiration (FNA) and core swab in isolating the pathogens. Staphylococcus aureus was the predominant isolate from surface core swab FNA and surface swab. In our study the correlation between surface swab with core swab was 47.
