introduction: antibiotic resistance among bacteria in particular those producing extended spectrum beta lactamases (es- bls) has a very significant role in hospital acquired infections. some of the gram negative bacilli including klebsiella pneu- monia and escherichia coli are known to be esbl producers which cause uncontrollable infections because they are also often resistant to other antimic...

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...

allergens in maltworkers with extrinsic allergic alveolitis than in the rest of the maltworker population, and (c) atopic maltworkers had a significantly lower rate of skin sensitivity to occupational allergens than non-atopic workers. The first observation is not surprising, since extrinsic allergic alveolitis is not due to a type 1 allergic reaction. The second is of interest, since it sugges...

In a period of two years, 865 strains of Gram-negative bacilli other than Pseudomonas aeruginosa isolated from burns were identified by a range of tests. The commonest species were Proteus mirabilis, Escherichia coli, and Enterobacter cloacae. Many strains of Klebsiella aerogenes, Enterobacter aerogenes, and Bacterium anitratum were also found.A large proportion of the strains were tested for s...

background: lower respiratory tract infections are among important causes of morbidity and mortality for all age groups. the emergence of multidrug resistant gram-negative bacilli is an issue of increasing concern. materials and methods: a retrospective study including respiratory specimens (sputum and bal) was conducted in our tertiary care centre. samples were processed for microscopy, cultur...
