A Decrease in Lactobacilli in the Vaginal Microbiota Is Independently Associated With HPV Persistence in Women With High-Risk HPV Infection.

Background Vaginal dysbiosis, an imbalance between species, can initiate some local changes in immune and metabolic signaling causing chronic inflammation. The mechanism of the clearance or progression of the HPV infection has not been uncovered yet. We hypothesized that vaginal dysbiosis may contribute to the persistence of the cervical HPV infection.

[Evaluation of blood culture practices: Use of system (Epicenter) data].

Sepsis is a serious clinical problem and estimated to be responsible for 18 million annual deaths worldwide. Therefore, the use and the rapid processing of blood cultures are important for the transition from empiric therapy to directed therapy. The aim of this study was to assess the best blood culture practices in Turkey.

[Comparison of genotypic and phenotypic characteristics in biofilm production of Staphylococcus aureus isolates].

Staphylococcus aureus which is an important pathogen, is known to have several virulence factors. The pathogenicity of S.aureus isolates are related with features like adherence, various toxins, enzymes, structural and extracellular factors.

[Evaluation of virulence factors in enterococcus species].

Enterococci have recently become important due to their increased isolation rates in community-based and nosocomial infections and resistance to many antibiotics, including glycopeptides. The aim of this study was to evaluate the antimicrobial susceptible patterns and virulence factors of various clinical specimens; urine (n= 149), blood (n= 38), wound (n= 17), stool (n= 13), and other (n= 12) with a total of 229 enterococci including 138 E.faecalis and 91 E.

Fosfomycin Addition to Poly(D,L-Lactide) Coating Does Not Affect Prophylaxis Efficacy in Rat Implant-Related Infection Model, But That of Gentamicin Does.

Gentamicin is the preferred antimicrobial agent used in implant coating for the prevention of implant-related infections (IRI). However, the present heavy local and systemic administration of gentamicin can lead to increased resistance, which has made its future use uncertain, together with related preventive technologies. Fosfomycin is an alternative antimicrobial agent that lacks the cross-resistance presented by other classes of antibiotics.

[Investigation of the effect of ibuprofen on wound healing in experimental Staphylococcus aureus soft tissue infections].

Soft tissue infections (STIs) occur as a result of the colonization of pathogenic bacteria upon the destruction of normal skin microbial flora and the skin integrity. Streptococci and staphylococci are the most frequent causes of bacterial STIs. Non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen are often used in STIs because of their analgesic and antipyretic effects.

[Investigation of macrolide, lincosamide and streptogramin B resistance in Staphylococcus aureus strains isolated from clinical samples by phenotypical and genotypical methods].

Staphylococcus aureus is one of the most common cause of both community and healthcare-associated infections. As staphylococci have developed resistance to various antibiotics, initially to penicillins then to methicillin and glycopeptides and have the ability to cause epidemics, they continue to be a major problem from past to present. Methicillin resistance gave rise to the use of alternative antibiotics such as macrolides, however worldwide development of macrolide resistance limited the use of these antibiotics.

[Investigation of Bartonella henselae antibodies in serum and plasma samples of kidney transplant patients].

Solid organ transplantation is an important therapeutic choice to improve the life quality of patients with end-stage renal disease. Renal transplant recipients have to take immunosuppressive therapy to prevent transplant rejection. However, this treatment increases susceptibility to infection.

[Investigation of mold fungi in air samples of elementary schools and evaluation of allergen-specific IgE levels in students' sera].

Atmospheric fungal spores play important role in allergic reactions in atopic individuals. Monitorization of those spores found in the environment of atopic cases is crucial for the choice of the antigens that will be included in allergen screening procedures and precautions to be taken against mold-originated health problems. Since most of the people spend plenty of time indoors in recent years, the effects of exposure to indoor air fungi on human health have gained importance.
