Influenza virus neuraminidase (NA) cleaves terminal sialic acid residues on oligosaccharide chains that are receptors for virus binding, thus playing an important role in the release of virions from infected cells to promote the spread of cell-to-cell infection. In addition, NA plays a role at the initial stage of viral infection in the respiratory tract by degrading hemagglutination inhibitors...

Statistical comparisons of the floras associated with juvenile periodontitis, severe periodontitis, and moderate periodontitis indicated that differences in the bacterial compositions of affected sites in these populations were not statistically significant. The subgingival flora of affected juvenile periodontitis sites was statistically significantly different from the adjacent supragingival f...

Endocrine pathology, including diabetes mellitus, significantly affects the immune response characteristics to microbial invasion and, as a result, balance of oral cavity in normal conditions and periodontal diseases. The aim study was evaluate antimicrobial efficacy mild periodontitis nonsurgical treatment patients with type II mellitus different duration endocrine disease. It is shown that be...

Introduction Cross-linked hyaluronic acid (HA) gel is widely used in esthetic medicine. Late bacterial infection (LBI) is a rare, but severe complication after HA augmentation. The aim of this study was to determine whether patients who underwent the HA injection procedure and developed LBI had qualitatively different bacterial flora on the skin compared to patients who underwent the procedure ...

Garter snakes that are used for scientific laboratory studies or kept as exotic pets often become ill and die early in captivity. They may also act as reservoirs of potential human pathogens or transmit infection to man. A total of 126 strains of aerobic and facultative bacteria, most potential human and snake pathogens, were isolated from 82 garter snake oropharyngeal cultures. Coagulase-negat...

PURPOSE OF REVIEW Probiotics are live, nonpathogenic bacteria that confer health benefits beyond their nutritional value. In inflammatory bowel disease, where changes in bacterial flora have been demonstrated, there is an increasing interest in modulating the flora with probiotic strains. The beneficial effect of probiotics is demonstrated mainly in pouchitis and ulcerative colitis; however, th...

In the human oral cavity, which is an open growth system, bacteria must first adhere to a surface in order to be able to colonize. Ability to colonize a non-shedding tooth surface is necessary prior to any odontopathic or periodontopathic process. Complex microbe-host relationships occur and must be studied before the commensal-to-pathogenic nature of the human indigenous oral flora can be unde...

Bachtiar et al. (2014) present a very interesting study in which they illustrate the ability of AI-2, produced by Aggregatibacter actinomycetemcomitans to inhibit biofilm formation by the fungal opportunistic pathogen Candida albicans. C. albicans is considered to be the most common fungal pathogen of humans, manifesting itself in the oral cavity (oral candidiasis or thrush), female reproductiv...

OBJECTIVE To investigate the microbial and cytopathological changes and genital symptoms in oral contraceptive pill (OCP) and intrauterine contraceptive device (IUCD) users. METHODS Included in the study were 34 women using OCP and 34 women using IUCD for 24 to 36 months period and 34 women as control group. We conducted the study between March to September 2005 in Antakya Maternity Hospital,...

It is well known that various kinds of hard cheese, such as Cheddar and Emmental, or Swiss, depend on a suitable bacterial flora for their normal development. The two types of cheese mentioned have been studied extensively by a number of investigators. It has been shown that in the manufacture of Cheddar cheese there must be a rapid development of the lactic-acid bacterium Streptococcus lacticu...
