Background. Escherichia coli is a highly clonal pathogen. Extraintestinal isolates belong to a limited number of genetically related groups, which often exhibit characteristic antimicrobial resistance profiles. Methods. We developed a rapid clonotyping method for extraintestinal E coli based on detection of the presence or absence of 7 single nucleotide polymorphisms (SNPs) within 2 genes (fu...
OBJECTIVES To test the antimicrobial sensitivity of two periodontal pathogens to a panel of five orally administrable antibiotics in periodontal disease. STUDY DESIGN A total of 69 isolates of Aggregatibacter actinomycetemcomitans and Porphyromonas gingivalis were processed using culture and biochemical tests. Selected colonies of A. actinomycetemcomitans and P. gingivalis were used to evalua...
A prospective study was conducted of the rapid FASTPlaque-Response test for determination of rifampicin resistance in Mycobacterium tuberculosis with and without the addition of an antimicrobial supplement containing nystatin, oxacillin and aztreonam (NOA) to control specimen-related contamination. A total of 631 smear-positive sputum specimens was tested. The age of specimens ranged from 0 to ...
The aim of the study was to investigate phytochemical properties, antimicrobial activity and trace metal concentrations of Caesalpinia bonducella. The phytochemical screening of the extracts of leaves of C. bonducella revealed the presence of bioactive compounds such as Steroid, Triterpenoids, Reducing Sugar(A), Reducing Sugar(B), Sugars, Flavonoids, Saponin, Amino acids with absence of Alkaloi...
Serratia marcescens has become an important nosocomial pathogen. During a period of seven years 123 strains, both pigmented and non-pigmented varieties were isolated. Their biochemical characteristics, antibiotic susceptibility pattern and clinical significance are described. The aminoglycosides appeared to be the most effective agents against this organism. "Compromised" patients were most vul...
background & aim: by increasing resistance of fish pathogens to chemical drugs, using herbal plants with antimicrobial properties is necessary.in this study, the composition of the essential oil and antimicrobial activity of aerial parts of achillea wilhelmsii c.koch growing wild in zagross mountain (southwest of iran) was analyzed against common bacterial and fungal pathogens of fish. expe...
This study was performed to detect cultivable canine gastric Helicobacter-like organisms (GHLO’s) and to evaluate their sensitivity to common antibiotics in two groups of naturally infected dogs (pets and stray dogs). Gastric samples were taken from the body and antrum of 30 pets and 30 stray dogs. From each part of canine gastric mucosa, four gastroscopic samples were used for impression smear...
