sunflower is one of four main annual oil plants that cultivated in oil and nut varieties. this plant as an important and industrial food product and because of nutritional features and the potential for earning exchange has become a valuable product in foreign and inner markets and has a special position in agricultural sector. khoy, by producing 40 percent of sunflower productions of country a...

Restriction fragment length polymorphism (RFLP) analysis with probes derived from the insertion element IS6110, the direct repeat sequence, and the polymorphic GC-rich sequence (PGRS) and a PCR-based typing method called spacer oligonucleotide typing (spoligotyping) were used to strain type Mycobacterium bovis isolates from the Republic of Ireland. Results were assessed for 452 isolates which w...

During 1994-1996, Shigella sonnei outbreaks occurred in 8 North American traditionally observant Jewish communities. These communities remain relatively separate from neighboring populations while maintaining close contact by travel with coreligionists in other cities. Epidemiologic investigations suggested community-to-community transmission via travel. Outbreak-related and control isolates of...

Geographic variation in drug susceptibility among isolates of Streptococcus pneumoniae has influenced national treatment guidelines for community-acquired pneumonia. Whether individual hospital susceptibility data provide reliable and valid information for providers is unclear. We examined the geographic and temporal variability in hospital-reported rates of pneumococcal susceptibility. We surv...

In a previous study on the restriction enzyme analysis of genomes of ASFV isolates from Cameroon (8) it was shown that there are probably two genetically very closely related virus groups persisting within the pig population in the country; one group consists of the CAM/82, CAM/85 CAM/87 and CAM/88 ASFV isolates while the other includes the CAM/86 isolate only. The main differences between the ...

Duplex PCR was developed to screen Salmonella enterica serovar Typhimurium phage type DT104 and related strains in Thailand because a phage typing laboratory of serovar Typhimurium is not available. Of 46 isolates of serovar Typhimurium and 32 isolates of S. enterica serovar 1,4,[5],12:i:-, 15 (33%) and 30 (94%) were duplex PCR positive, respectively. All isolates were submitted for phage typin...

candida is an asexual, diploid, dimorphic fungus that is present on human body and his environment. nowadays the number of patients, who are immunocompromised, aged, receiving prolonged antibacterial and aggressive cancer chemotherapy or undergoing invasive surgical procedures and organ transplantation, is on increase, and therefore candidiasis emerged itself as an alarming opportunistic diseas...

From January 1996 to December 1997, 200 isolates of Streptococcus pneumoniae recovered from 200 patients treated at National Taiwan University Hospital were serotyped and their susceptibilities to 16 antimicrobial agents were determined by the agar dilution method. Sixty-one percent of the isolates were nonsusceptible to penicillin, exhibiting either intermediate resistance (28%) or high-level ...

32 Although Escherichia coli (E. coli) typically colonize the intestinal tract and vagina 33 of the giant pandas, it has caused enteric and systemic disease in the giant pandas 34 and greatly impact the health and survival of this endangered species. In order to 35 understand the distribution and characteristics of E. coli from giant pandas, 67 fecal 36 and 30 vaginal E. coli isolates from 21 g...

BACKGROUND The blaZ gene encoding penicillin resistance can be located either chromosomally or on plasmids. The aim of this study was to investigate the genetic relationships and to determine the location of the blaZ gene in S. aureus isolated in bovine mastitis in Finland and Sweden. METHODS Seventy-eight β-lactamase positive S. aureus isolates from bovine mastitis (34 from Finland and 44 fr...
