FMT Restores Colonic Protein Biosynthesis and Cell Proliferation in Patients with Recurrent Disease.

Recurrent infection (CDI) is a major health threat with significant mortality and financial costs. Fecal Microbiota Transplantation (FMT) is an effective therapy, however the mechanisms by which it acts, particularly on the host, are poorly understood. Here we enrolled a prospective cohort of human patients with recurrent CDI (n=16) undergoing FMT therapy.

Eradication of Blastocystis in humans: Really necessary for all?

Blastocystis (initially named as Blastocystis hominis) has long been known as a protist without any clinical significance. However, there is now a huge pile of case reports where Blastocystis is blamed for the symptoms and the infection described in the patients. Introduction of the presence of as many as 17 Blastocystis subtypes while many infected individuals are non-symptomatic initially brought about the correlation between the subtypes and pathogenicity; however, the outcomes of these trials were not consistent and did not explain its pathogenicity.

Blastocystis subtypes in irritable bowel syndrome and inflammatory bowel disease in Ankara, Turkey.

Blastocystis infection has been reported to be associated with irritable bowel syndrome (IBS), inflammatory bowel disease (IBD) and chronic diarrhoea. The availability of data on the subtypes of Blastocystis found in these patient groups would be of interest in understanding the significance of Blastocystis infection in chronic illness. In this study, we identify Blastocystis subtypes found in patients presenting with IBS, IBD, chronic diarrhoea and asymptomatic patients in Ankara, Turkey.

Investigation of the prevalence of amoebiasis in Izmir province and determination of Entamoeba spp. using PCR and enzyme immunoassay.

Amoebiasis is a common and life-threatening disease. The discrimination of the pathogenic Entamoeba histolytica from the non-pathogenic Entamoeba dispar could be done by advanced methods such as enzyme immunoassay (EIA) and PCR. The aim of this study was to investigate the prevalence of amoebiasis in Izmir province, and differentiate the Entamoeba species by PCR and EIA.

The prevalence of intestinal parasites in the province of Izmir, Turkey.

Stool samples of a total of 2,047 people in Izmir province were examined by wet mount, formalin ethyl acetate concentration, and trichrome staining methods with an aim to reveal the prevalence of intestinal parasites in Izmir together with related personal and environmental risk factors. Geographical mapping showing the density and variation of the species of intestinal parasites in Izmir was done after all maps were scaled, and the coordinates were determined with GeoMedia5.0.

Case report: Isospora belli infection in a renal transplant recipent.

Isospora belli, an opportunistic protozoon, is one of the most commonly recognized causes of diarrhea in patients with acquired immunodeficiency syndrome (AIDS). Infection is acquired through fecal contaminated food or water, and generally diagnosed by examination of stool and/or duodenum biopsy specimens with acid-fast staining. Here, we present an uncommon case, chronic diarrhea caused by I.

In vitro antimicrobial activity of propolis samples from different geographical origins against certain oral pathogens.

Propolis is an agent having antimicrobial properties, however, its composition can vary depending on the area where it is collected. In the present study, the antimicrobial activity of five propolis samples, collected from four different regions in Turkey and from Brazil, against nine anaerobic strains was evaluated. Ethanol extracts of propolis (EEP) were prepared from propolis samples and we determined minimum inhibitory concentrations (MIC) and minimum bactericidal concentrations (MBC) of EEP on the growth of test microorganisms by using agar dilution method.

Two cases of rarely recognized infection with Entamoeba moshkovskii.

We report two cases (a 36-year-old woman and 2-year-old girl) infected with Entamoeba moshkovskii in Turkey. Entamoeba moshkovskii was identified and distinguished from the morphologically identical parasites E. histolytica and E.

The scolicidal effects of honey.

Echinococcosis is a zoonosis that is caused by adult or larval tapeworms belonging to the genus Echinococcus. Until now, no studies have sought to determine the scolicidal effects of honey. Therefore, the present study was undertaken to explore the scolicidal effects of honey in different concentrations for various exposure times.

Evaluation on scolicidal efficacy of propolis.

Background: Propolis is a resinous material collected by bees from various plants. It has antimicrobial, antioxidative, immunostimulative, and regenerative properties. We determined the scolicidal effect of propolis in different concentrations and various exposure times.

Co-infection of Giardia intestinalis and Cyclospora cayetanensis in an immunocompetent patient with prolonged diarrhea: case report.

Cyclospora cayetanensis is an agent of emerging infectious disease, and a recognized cause of diarrhea in some patients. Also, the flagellated protozoan, Giardia intestinalis, induces a diarrheal illness of the small intestine. Cases of cyclosporiasis are frequently missed, primarily due to the fact that the parasite can be quite difficult to detect in human fecal samples, despite an increasing amount of data regarding this parasite.

Saccharomyces boulardii and infection due to Giardia lamblia.

Therapy with metronidazole is the recommended option in giardiasis. However, some clinical trial reports suggest the appearance of drug resistance to explain therapeutic failure. Several investigations have been carried out on the effect of probiotic microorganisms for preventing or treating gastrointestinal diseases, but little is known about their efficacy against protozoal infections.

Is the incidence of malaria decreasing in endemic area of Turkey?

Much international business and tourism travels occur, as well as the deployment of soldiers to other places. The aim of this study was both to determine incidence of malaria in the military hospital, Diyarbakir, southeast region of Turkey, and to point out the incidence of this disease. During the study period (1997-2004), 609 cases were found in a military hospital, which is in an endemic area for vivax malaria.

Comparison of two methods (microscopy and enzyme-linked immunosorbent assay) for the diagnosis of amebiasis.

Diagnosis of amebiasis is usually performed on a clinical basis alone in most endemic countries having limited economic resources. This epidemiological study was conducted using modern diagnostic tests for amebiasis in the southeastern region of Turkey, an endemic area for amebiasis. The population of this study included patients with symptomatic diarrhea/dysentery attending both Yuzuncu Yil University, Van and Harran University, Sanliurfa, Turkey.

Background: The medicinal use of maggots for the biological debridement of chronic wounds is increasing around the world, due to its efficacy, safety and simplicity. Thousands of patients have been treated in private and governmental hospitals during the last 10 years.

Objective: To examine the efficacy of maggot debridement therapy (MDT) in the debridement of chronic wounds in a military hospital.

Classification of Giardia duodenalis parasites in Turkey into groups A and B using restriction fragment length polymorphism.

PCR-RFLP (restriction fragment length polymorphism) analysis was used to determine the relation of Giardia duodenalis Groups A and B. Of these, 17 (85%) were found as Group A in symptomatic cases; 22 (92%) were Group B in asymptomatic cases by using PCR-RFLP (p < 0.001).

Performance of the immunoglobulin G avidity and enzyme immunoassay IgG/IgM screening tests for differentiation of the clinical spectrum of toxoplasmosis.

Toxoplasmosis has been well known as an important human infection to consider especially in pregnant women. Although many serologic methods are available, the diagnosis of toxoplasmosis can be extremely difficult. The presence of increased levels of Toxoplasma-specific IgG antibodies indicates an infection, but it does not differentiate between a recent and past infection.

Transient hypogonadotrophic hypogonadism in males with acute toxoplasmosis: suppressive effect of interleukin-1 beta on the secretion of GnRH.

Background: In September 2002, an outbreak of toxoplasmosis was noted in a male boarding high school on the Aegean coast of Turkey. We have focused our efforts to investigate the sex hormones in this population.

Methods: Blood samples were collected from 40 male patients, 17-18 years old, who also had positive titres of antibody to Toxoplasma gondii.

In our study, 20,612 schoolchildren (10,367 boys, 10,245 girls) were examined for Pediculus humanus capitis in 36 elementary schools between December 1996 and February 1998 in Ankara, Turkey. The prevalence of pediculosis capitis infestation was found to be 3.

Determination of intracellular efficacies of azithromycin against Leishmania major infection in human neutrophils in vitro.

Azithromycin is one of a new class of antibiotics known as azalides. Azithromycin has high tissue affinity and this feature is thought to be due to the presence of two basic tertiary amine groups. Leishmania major, one of the causative agents of cutaneous leishmaniosis, is an obligate intracellular parasite.

Detection of Cryptosporidium parvum infection in childhood using various techniques.

Background: The protozoan parasite Cryptosporidium parvum, which causes acute gastroenteritis in both humans and animals, has become an important pathogen all over the world. C. parvum may cause asymptomatic or symptomatic acute infections of the digestive system in immunocompetent subjects, but life-threatening disease in immunocompromised hosts.

Entamoeba histolytica: sequence conservation of the Gal/GalNAc lectin from clinical isolates.

The Gal/GalNAc lectin gene of Entamoeba histolytica is a major amebic virulence protein responsible for interaction with host tissues. We investigated sequence differences in the Gal/GalNAc lectin heavy subunit in three isolates from Bangladesh and one isolate from Georgia, each of which was determined to be genetically distinct by SREHP AluI digestion. Interestingly, we observed only slight genetic diversity in the lectin gene as compared with the HM1:IMSS laboratory strain, originally a clinical isolate from Mexico.
