The rise in carbapenemases-producing organisms has challenged the scientific community. Infections caused by these bacteria have limited treatment options. There are various types such as Klebsiella pneumoniae carbapenemase (Ambler class A), metallo-beta-lactamases of VIM-type, IMP-type, NDM-type (Ambler class B), and OXA-48-types (Ambler class D). An efficient strategy for detection of carbapenemase producers is important to determine the appropriate therapeutic modalities. In this study, four methods - Carba NP test, modified Carba NP (MCNP) test, carbapenem inactivation method (CIM) test, and Rapidec Carba NP kit test were evaluated. We evaluated an in-house MCNP test to detect carbapenemase production using a single protocol which gave reliable results. Furthermore, CIM using routine antibiotic discs gives good results. Both these tests were found to be cost-effective.

Conidiobolomycosis caused by Conidiobolus species is an uncommon infection restricted to tropical and subtropical regions, usually affecting immunocompetent individuals. More than half of pediatric cases of conidiobolomycosis across the globe are from India. We report a case of subcutaneous conidiobolomycosis in an adolescent with development delay who responded to combined therapy with itraconazole and saturated solution of potassium iodide.
