The genomic diversity of 99 T4-like coliphages was investigated by sequencing an equimolar mixture with Illumina technology and screening them against different databases for horizontal gene transfer and undesired genes. A 9-phage cocktail was given to 15 healthy adults from Bangladesh at a dose of 3×10(9) and 3×10(7) plaque-forming units and placebo respectively. Phages were detected in 64% of...

Reported efficacies of drugs used to treat Strongyloides stercoralis infection vary widely. Because diagnostic methods are insensitive, therapeutic trials generally require multiple negative posttreatment stool specimens as evidence of drug efficacy. However, only a single positive stool specimen is usually required for study enrollment. To determine the reproducibility of detection of S. sterc...

BACKGROUND Strongyloides stercoralis, the chief causative agent of human strongyloidiasis, is a nematode globally distributed but mainly endemic in tropical and subtropical regions. Chronic infection is often clinically asymptomatic but it can result in severe hyperinfection syndrome or disseminated strongyloidiasis in immunocompromised patients. There is a great diversity of techniques used in...

Some of the lowest voltages used in radiotherapy are termed Grenz and superficial X-rays of ~ 20 and ~ 100 kVp, respectively. Dosimetrically, the surface doses from these beams are calculated with the use of a free in-air air kerma measurement combined with a backscatter factor and the appropriate ratio of mass energy absorption coefficients from the measurement material to water. Alternative t...

Background: Rotavirus is a major cause of acute diarrhea in children worldwide. It is an important cause of death among young children in developing countries. The aim of this study was to evaluate the prevalence of rotavirus infection in children less than five years old hospitalized for gastroenteritis in Jahrom. Methods: One hundred and two stool samples were collected from children less tha...

Sheehan et al. (3) and Pikula (Z. P. Pikula, Letter, J. Clin. Microbiol. 25:1581, 1987) bear witness to the fact that Blastocystis hominis is a common inhabitant of the human intestinal tract. These authors, like those they cite, have found B. hominis in some persons in whom they identified none of the commonly recognized pathogens, and in others in association with recognized pathogenic protoz...

background: among the most important parasitic disease, causing diarrhea, gi­ardia lamblia is noteworthy. nowadays detection methods for these parasites in­clude parasitological methods such as microscopic examination. the sensitivity of these methods relies on the expertise and experience of examiners. in contrast, molecular methods such as pcr are less dependent on the expertise of the exam­i...

OBJECTIVE To investigate the impact of zinc supplementation in children with cholera. DESIGN Double blind, randomised, placebo controlled trial. SETTING Dhaka Hospital, Bangladesh. PARTICIPANTS 179 children aged 3-14 years with watery diarrhoea and stool dark field examination positive for Vibrio cholerae and confirmed by stool culture. INTERVENTION Children were randomised to receive 3...

conclusions with regards to the high incidence of gasterointestinal parasitic diseases and also because of asymptomatic cases of giardiasis, we recommend evaluation of pediatric patients with malignant lymphohematopoitic disease by at least two different diagnostic methods and three rounds of stool examination in order to prevent possible life threatening outcomes. coproparasitoscopic study for...

BACKGROUND Cryptosporidium is an intracellular protozoan organism which causes diarrhea, both in immunocompetent and immunocompromised hosts. Renal transplant recipients are prone to develop a variety of infections including protozoal infections. OBJECTIVES The aim of this study was to determine the prevalence of cryptosporidiosis in our renal transplant recipients presenting with acute diarr...
