From September 1990 to October 1990, 15 patients who were admitted to four different departments of the National Taiwan University Hospital, including nine patients in the emergency department, three in the hematology/oncology ward, two in the surgical intensive care unit, and one in a pediatric ward, were found to have positive blood (14 patients) or pleural effusion (1 patient) cultures for B...

the aim of the study was to determine the resistance patterns of pseudomonas aeruginosa isolates recovered from patients with surgical wounds in hospitals and also to investigate their epidemiological relatedness using molecular typing techniques. twenty pseudomonas sp. isolated from surgical wounds were subjected to antibiotic susceptibility testing by disk diffusion, plasmid profile, sds-page...

background candiduria is a rising condition among hospitalized patients and candida albicans is the most common recovered agent. however, non-albicans candida species (nacs) such as c. glabrata, c. krusei, c. parapsilosis, and c. tropicalis are also important. although most candida species especially c. albicans are sensitive to routinely used antifungals, an increasing trend in resistance has ...

A survey was done for the most common yeast isolates from different clinical sources from human and animals in addition to environment samples from soil in El-Fayoum Governorate. The total of tested samples was 802 clinical and environmental samples. They consisted of fifty human vaginal swabs, seventy one human throat swabs, three hundred fifty seven animal vaginal swabs, one hundred seventy n...

Background: the most widely distributed and virulent Grapevine leafroll-associated viruses (GLRaV) that affect grapevine are GLRaV-1 GLRaV-3, transmitted semi-persistently by different mealybugs soft scales, mainly causing downward rolling of leaf margins interveinal reddening. Methods: main objectives this study were to investigate genetic structure molecular diversity GLRaV-3 in 617 samples f...

Expression of resistance to Meloidogyne incognita and M. javanica from Aegilops squarrosa was studied in a synthetic allohexaploid produced from Triticum turgidum var. durum cv. Produra and Ae. squarrosa G 3489. The reproductive rate of different races of M. incognita and M. javanica, expressed in eggs per gram of fresh root, was low (P < 0.05) on the synthetic allohexaploid and the resistant p...

seventy poultry farms’ drinking water was tested for escherichia coli contamination in qom province iniran. the cases of colibacillosis from positive farms were also collected and tested. the isolates wereexamined for serotype, detection of virulence genes by multiplex pcr and antibiotic resistance. thirtypoultry farm water samples were e. coli positive (18.57%), although 13 e. coli isolates we...

Phylogenetic analysis has shown that Escherichia coli is composed of four main phylogenetic groups (A, B1, B2 and D). Characterization of phylogenetic groups is of clinical interest, as group A and B1 generally associated with commensals, whereas most enteropathogenic isolates are assigned to group D, and group B2 is associated with extra-intestinal pathotype. One hundred E. coli strains recove...
