Antibiotic-resistant anaerobic bacteria have become increasingly recognized as a confounding factor in the selection of therapeutic agents. The use of potent, broad-spectrum antibiotics as empirical therapy, along with appropriate adjunctive measures, has, in some ways, masked the magnitude of the antibiotic resistance problem that parallels that observed for nonanaerobic pathogens. The use of ...

Extended-spectrum β-lactamase (ESBL)-producing Enterobacteriaceae with Cefotaximase-München (CTX-M) enzymes are rapidly increasing worldwide and pose a threat to health care. ESBLs with CTX-M enzymes have been isolated from animals and different food products, but it is unknown if food imported from the Mediterranean area may be a possible reservoir of these bacteria. During 2007-2008, swab sam...

ISSN: 2319-7706 Volume 4 Number 5 (2015) pp. 172-190 http://www.ijcmas.com Neonatal sepsis is a leading cause of neonatal mortality in developing countries. Identification of the etiological agents of neonatal sepsis is essential for effective treatment. Out of 106 microbial isolates recovered from blood cultures of late onset neonatal sepsis (LONS) patients, only 70 (66 %) isolates were Gram-p...

OBJECTIVES 1) To determine the prevalence of Streptococcus pneumoniae, Haemophilus influenzae and Moraxella catarrhalis in middle ear effusions of children with otitis media with effusion undergoing myringotomy; 2) to compare the results obtained by culture and PCR; and 3) to determine the susceptibility of bacterial isolates to penicillin. METHODS We analyzed 128 middle ear effusion specimen...

Cytolethal distending toxin (CDT) is a newly identified virulence factor produced by several pathogenic bacteria implicated in chronic infection. Seventy three strains of periodontopathogenic bacteria were examined for the production of CDT by a HeLa cell bioassay and for the presence of the cdt gene by PCR with degenerative oligonucleotide primers, which were designed based on various regions ...

Tetracycline is a broad-spectrum antibiotic used in humans, animals, and aquaculture; therefore, many bacteria from different ecosystems are exposed to this antibiotic. In order to determine the genetic basis for resistance to tetracycline in bacteria from the oral cavity, saliva and dental plaque samples were obtained from 20 healthy adults who had not taken antibiotics during the previous 3 m...
