A Method of Universal Primer Design for The Detection of Diverged CTX-M Beta-Lactamases in Multi-Drug Resistant Superbugs
Abstract: Complexity of many diverged β-lactamases in common multi-drug resistant bacteria has reached very high level. We found >40% of common bacteria in Kolkata water bodies were ampicillin resistant and reported clinical isolates were >95% ampicillin resistant worldwide. More than twenty unique sequence classes of β-lactamases were known to cause MDR inactivating penicillin, cephalosporin and carbapenem drugs. Further, there are other diverged MDR genes like drug efflux genes (acrAB, mexAB-EF, tetA), …

Molecular Diagnosis of Rifampicin Antibiotic Resistance in Mycobacterium Avium Subspecies Paratuberculosis Isolated from Sheep Clinical Samples
Abstract: The present study was conducted to identify parts of the rpoB gene in MAP of Indian sheep isolates. The rpoB gene (Beta sub unit of RNA polymerase) is involved in conferring the rifampicin antibiotic resistance in MAP bacteria. The resistance is due to the presence of mutations in the 81 bp variable region of the rpoB gene including C1367T and T1442C mutations identified by several workers. The study was further …
