[Detection of virulence factors and antifungal susceptibilities of Fusarium strains isolated from keratitis cases].

Fusarium species have gained importance as a cause of keratitis. The pathogenicity and virulence factors of genus Fusarium remain largely unknown. Several putative virulence factors have been reported for fungal pathogens, including biofilm formation, production of proteinases and other hydrolytic enzymes.

The characteristics of indoor and outdoor fungi and their relation with allergic respiratory diseases in the southern region of Turkey.

Indoor and outdoor fungal exposure has been shown to be associated with the development of allergic respiratory diseases. The aim of the study was to investigate the types and concentrations of airborne fungi inside and outside homes and evaluate the association between fungal levels and allergic diseases in the southern region of Turkey. A total of 61 children admitted with respiratory complaints to the pediatric allergy clinic between September 2007 and November 2008 were included in this study.

Evaluation of Antifungal Efficacy of 0.1% and 0.25% Riboflavin with UVA: A Comparative In Vitro Study.

Purpose: Antifungal efficacy of photochemical cross-linking (PACK-CXL) with 0.1% and 0.25% riboflavin was evaluated with a comparative in vitro study.

[Investigation of the clonal relationship between nosocomial Acinetobacter baumannii isolates by Rep-PCR].

Acinetobacter spp. are opportunistic bacterial pathogens primarily associated with hospital-acquired infections and the spread of multidrug resistant Acinetobacter strains is a growing problem in terms of infection control. The aim of this study was to determine the clonal relationship between strains of nosocomial Acinetobacter baumannii by using rep-PCR method.

[Detection of Helicobacter pylori and antimicrobial resistance in gastric biopsy specimens].

Helicobacter pylori is reported as the etiological agent of gastritis, gastric and duodenal ulcer, gastric adenoid carcinoma and mucosa-associated lymphoid tissue lymphoma. In the diagnosis of H.pylori infections invasive (culture, histopathological examination, rapid urease test and molecular tests) and non-invasive (urea breath test, serological tests, stool culture and stool antigen/nucleic acid tests) methods may be used.

[Investigation of the presence of Cryptosporidium spp. in different water sources in Mersin province, Turkey].

Cryptosporidium is an intracellular protozoon that causes enteritis in human and animals. Contaminated water and food are the major sources for the transmission of oocysts via oral-fecal route. It is reported that the prevalence of cryptosporidiosis is higher in developing countries than developed countries because of inefficient sanitation and disinfection facilities for drinking water.

[Identification of filamentous fungi isolated from clinical samples by two different methods and their susceptibility results].

Molds are widely distributed in nature. Aspergillus spp. represent the most frequently observed causative agents, however less frequent pathogens Fusarium, Scedosporium and Zygomycetes have also been considered the most important causes of morbidity and mortality in profoundly immunosuppressed hosts.

Increase in Candida parapsilosis fungemia in critical care units: a 6-years study.

Objectives: We aimed to asses possible clinically significant differences between C. parapsilosis and other candida species candidemia receiving care in the intensive care unit (ICU) setting.

Methods: The study included 118 adult patients diagnosed as candidemia after admission to the ICU of a university hospital between January 2004 and December 2009.

[Investigation of aflatoxin M1 levels in raw and market milks in Mersin Province, Turkey].

Aflatoxin M1 (AFM1) which is produced by some Aspergillus species, mainly Aspergillus flavus, is the hydroxylated metabolite of aflatoxin B1 (AFB1) and can be found in milk and dairy products of livestock fed with contaminated feed. AFM1 is a potential threat to human health owing to its toxic and carcino- genic effects. This study was aimed to investigate the level of AFM1 in raw and ultra-high-temperature pasteurized (UHT) milk samples.

Does Helicobacter pylori have a role in the development of chronic otitis media with effusion? A preliminary study.

Objective: To investigate the possible relationship between chronic otitis media with effusion (COME) and Helicobacter pylori (HP).

Patients And Methods: Twenty-five patients (7 girls and 18 boys; age range 2-10 years, mean age 7.8 years) with COME with or without adenotonsillary disease were included in this study.

Molecular identification, genotyping, and drug susceptibility of the basidiomycetous yeast pathogen Trichosporon isolated from Turkish patients.

Deep-seated infections due to Trichosporon species are emerging mycoses that have a very poor prognosis in patients with persistent neutropenia. This study elucidated the mycological characteristics of Trichosporon strains obtained from deep-seated infections in Turkish patients and identified by DNA sequence analysis of intergenic spacer (IGS) region 1 of the rDNA locus. In addition, we genotyped the major causative agent, T.

Does Helicobacter pylori play a role in etiology of nasal polyposis?

Objective: Investigation of the possible relation between nasal polyposis (NP) and Helicobacter pylori (HP).

Patients And Methods: Biopsy specimens of 25 patients with NP were evaluated. There were 16 men and 9 women enrolled in the study (NP) group.

[Investigation of Cryptosporidium oocysts in elementary school students in Mersin].

Cryptosporidium parvum, a protozoon, is an obligate intracellular parasite which can cause fatal diarrheal disease in immunocompromised individuals. Cryptosporidium parvum and Cryptosporidium hominis are usually known to be transmitted from fecally contaminated drinking and tap waters. Because oocysts can be detected in asymptomatic healthy individuals and no safe and effective therapy for cryptosporidial enteritis is available, the importance of cryptosporidiosis is increased.

Consistence of miniexon polymerase chain reaction-restriction fragment length polymorphism and single-copy gene sequence analyses in discriminating Leishmania genotypes.

Recently, a new polymerase chain reaction (PCR)-restriction fragment length polymorphism (RFLP)-based assay had been developed using the miniexon sequences for genotyping Leishmania isolates. We had used this method for rapid diagnosis and genotyping of visceral and cutaneous leishmaniasis with the combination of microcapillary cultivation. In this study, we have evaluated this approach by examining genomic DNAs from 47 independent isolates, which were grouped into 19 genotypes of Leishmania subgenus complexes by sequence polymorphism of single-copy genes.

[Investigation of Cryptosporidium spp. oocysts in tap water, well water, sewage water and sea water in Mersin, Turkey.].

Cryptosporidium spp. are protozoa which only live in a host cell and may cause an infection that may result in the death of people with immune deficiency. It is known that Cryptosporidium parvum and Cryptosporidium hominis infections may be spread by contaminated well and tap waters.

An outbreak of Pichia ohmeri infection in the paediatric intensive care unit: case reports and review of the literature.

Since the first report in 1998, 10 cases of Pichia ohmeri infection have been reported in the literature. Here we present two new cases of P. ohmeri infection in the paediatric age group.

An outbreak of Dipodascus capitatus infection in the ICU: three case reports and review of the literature.

A mini epidemic of Dipodascus capitatus (teleomorph of Geotrichum capitatum) involving three cases is reported. The index case was pulmonary infection and a fulminant course of fungal infection, which resulted in the patient's death with acute myelocytic leukemia. In the other cases, the patients were simultaneously hospitalized, the first in the intensive care unit.

False positive HBsAg result in blood donors due to administration of three different recombinant DNA Hepatitis B vaccines.

Vaccines are the only effective defence mechanism against Hepatitis B. Vaccination may create "false positive" results since the immunologic agent of the vaccines and serologic marker are the same. This possibility first studied on adult subjects and no "false positive" was observed.
