Over two years, 9892 mid-stream urine samples from patients attending the Aga Khan University Hospital, Karachi were cultured. Significant bacterial growth was seen in 23.5% samples. Further identification of these organisms Eevealed 40% of E.coli, 16% Pseudomonas aeruginosa, 11% Klebsiella aerogenes, 5.0% Enterobacter sp., 13% Protdus sp., 4.0% Serratia liquifaciens, 1.0% Acinetobacter sp., 3....

Bacillus thermoglucosidasius A7 degraded phenol at 65 degrees C via the meta cleavage pathway. Five enzymes used in the metabolism of phenol were cloned from B. thermoglucosidasius A7 into pUC18. Nine open reading frames were present on the 8.1kb insert, six of which could be assigned a function in phenol degradation using database homologies and enzyme activities. The phenol hydroxylase is a t...

A lipase gene, lipK, and a lipase modulator gene, limK, of Pseudomonas sp. strain KFCC 10818 have been cloned, sequenced, and expressed in Escherichia coli. The limK gene is located immediately downstream of the lipK gene. Enzymatically active lipase was produced only in the presence of the limK gene. The effect of the lipase modulator LimK on the expression of active lipase was similar to thos...

A total of 37 street vended food samples were examined for bacterial and the colony forming units counts ranged from 4.5 × 10⁵ to 1.12 × 10⁶. The isolates were identified as Escherichia coli (37.5%), Pseudomonas aeruginosa (3.57%), Staphylococcus aureus (14.20%), Salmonella sp. (5.36%), Klebsiella sp. (10.71%), Shigella sp. (19.64%) and Enterobacter sp. (8.93%) respectively. All the 56 isolates...

Antimicrobial activity of the folklore medicinal plant species, Acalypha fruticosa in the part of stem bark by using three alcoholic solvents viz; petroleum ether, ethyl acetate and methanol were tested against ten human pathogenic bacteria viz., Pseudomonas aeruginosa, P. stutzeri, Escherichia coli, Micrococcus sp., Lactobacillus sp., Servatia sp., Moraxetta sp., Bacillus subtilis, B. Research...

citrus blast is one of the important diseases of citrus in north of iran. the disease causes considerable damage during and immediately after the cold seasons. the causal agents have epiphytic survival on diverse weeds during spring and summer. during 2009-2010, samples were collected from several candidate weed plants including: poa annua, phalaris canariensis, sorghum halepense, cynodon dacty...

The susceptibility of 4,929 unselected clinical isolates of bacteria to cefoxitin and cephalothin was determined by the single-disk method, using a computer-associated electronic zone analyzer to obtain, record, and process measurements of sizes of zones of inhibition. Both cefoxitin and cephalothin were effective against most gram-positive strains, including Staphylococcus aureus, S. epidermid...
