I have received many questions about whether immunizing with Reston virus could protect against infection with Ebola virus. Usually the question comes together with the statement ‘because Reston virus does not cause disease in humans’. I can think of two reasons why a Reston virus vaccine is not... Read More

Acinetobacter species are among the most common nosocomial pathogens that are notorious for multi-drug resistance. Their immense ability to acquire or upregulate antibiotic drug resistance determinants has established them as a successful pathogen, causing wide range of infections such as wound ... Read More

Pseudomonas aeruginosa, Escherichia coli and Serratia marcescens were inoculated into gelatin agar using the stab method and incubated for 1 week at 37 degree’s C. If the organism has gelatinase then it can break down the gelatin (protein) into polypeptides and then amino acids which can then ... Read More

A positive D test indicates that the presence of macrolide-inducible resistance to clindamycin produced by an inducible methylase enzyme that alters the common ribosomal binding site for macrolides, clindamycin and the group B streptogrammins (quinupristin). This cross-resistance, called the ML... Read More
