The widespread resistance in Gram-negative bacteria has necessitated evaluation of the use of older antimicrobials such as polymyxins. In the present study we evaluated the different susceptibility testing methods for polymyxins B and E against Gram-negative bacteria using the new Clinical and Laboratory Standards Institute (CLSI) guidelines. ⋯ The E-test and agar dilution methods showed good concordance with BMD. The disk diffusion method can be useful for initial screening in diagnostic laboratories.

Epidemics of severe cholera caused by El Tor Vibrio cholerae O1 Ogawa possessing the ctxB gene of the classical biotype in Orissa, India.
We investigated the epidemic of cholera that occurred in Kashipur and Dasmantpur blocks of Orissa, reported during July-September 2007. ⋯ This is the first report of the El Tor variant of V. cholerae O1 Ogawa having the ctxB gene of the classical strain with altered antibiogram causing epidemics of cholera in Orissa, India.

Adherence to treatment of latent tuberculosis infection in a clinical population in New York City.
Low adherence to treatment of latent tuberculosis infection (TLTBI) diminishes TB prevention efforts. This study examined the treatment completion rate among those who started TLTBI and factors associated with adherence to TLTBI. ⋯ Shorter regimen and DOPT increased completion rates for LTBI. Though efforts to improve TLTBI completion need to address all groups, greater focus is needed for persons who are contacts and HIV-infected, as they have higher risk of developing TB.

Case ReportsDisseminated Mycobacterium kansasii infection associated with hemophagocytic syndrome.
Disseminated infections with hemophagocytic syndrome caused by non-tuberculous mycobacteria (NTM) are rare. A 60-year-old woman, who presented with fever, chills, anorexia, and right upper quadrant pain, was admitted to our hospital. Hepatosplenomegaly, pancytopenia, elevated liver aminotransferases, and hyperferritinemia were noted after admission. ⋯ Bone biopsy showed granulocytic sarcoma. To our knowledge, this is the first reported case of life-threatening hemophagocytosis due to M. kansasii. Patients with disseminated NTM infections should be closely monitored if any immunocompromising condition develops.

Infections associated with indwelling ventriculostomy catheters in a teaching hospital.
Ventriculostomy-associated infections are a serious complication of external ventricular drains. The objective of this study was to analyze the clinical features of and risk factors for such infections. ⋯ Repeated insertion and longer duration of drains are major risk factors for ventriculostomy-associated infections.
