Three different areas -hospital, food-handling establishments and human dwellings, were surveyed for pathogenic gram-negative bacteria carried on the cuticles of cockroaches. Fifty species of bacteria were identified from all cockroaches. Escherichia coli, Klebsiella pneumoniae, Citrobacter freundii and Enterobacter cloacae were the most frequently found. Pathogenic and potentially pathogenic b...

We do need them, and we need them now! New antibacterial drugs have been developed on the last 2 years for Grampositive agents,(1) but not with new targets. There has been real progress in developing antimycobacterial agents, including some new modes of action;(2) however, what we have available today for Gramnegative multiresistant bacteria is the same we had 5 years ago, except for some molec...

BACKGROUND Patients on renal replacement therapy experience higher rates of morbidity and mortality, infection being the second commonest cause of death. In our haemodialysis population, we identify the pathogens, sensitivity patterns, sources of infection and outcomes of Gram-negative bacteraemia. METHODS Data from the NHS Greater Glasgow & Clyde and NHS Forth Valley haemodialysis population...

Gingivitis is an inflammatory destructive disease mainly caused by microbial plaques. Gram-positive and gram-negative bacilli or cocci have been isolated from dental plaque and gingivitis. This study was going to isolate and characterize the pathogenic bacteria from gingival of 100 patients with oral gingivitis. Enriched and specific media used for isolation of bacteria. Identification of isola...
