The indirect fluorescent antibody test (IFAT) revealed seropositivity to Coxiella burnetii in aged non-laying chickens in poultry farms in a prefecture in the central part of Japan. Seropositivity was 7%, and antibody titers ranged from 16 to 64. No DNA fragment specific for C. burnetii was detected in the chickens by nested-PCR. The prevalence of C. burnetii infection in a prefecture of Japan ...

BACKGROUND Chlamydia trachomatis infection in pregnant women can lead to serious maternal/neonatal antenatal or postnatal complications. The aim of this study was to find out the quantum of this problem in antenatal cases of Command Hospital, Kolkata. METHODS Antibodies to C. trachomatis by ELISA method were tested in sera of 24 pregnant women and 10 nonpregnant controls. RESULTS Five (20.8...

Background: Blood is a scarce, but lifesaving resource; it is also the most efficient vehicle for the transmission of human immunodeficiency virus (HIV). Hence there is a need for accurate screening of HIV among blood donors. The present study was designed to assess the seroprevalence of HIV, among the blood donors in a tertiary care hospital, Andhra Pradesh. Methods: Prospective study over a p...

CagA seropositivity is an important risk factor for gastric adenocarcinoma and duodenal ulcer. However, CagA seropositivity is also found in Helicobacter pylori-seronegative subjects. Is CagA seropositivity in these subjects a sign of a past H. pylori infection, or does it represent a false-positive reaction? This study investigates the intensity of the CagA immune reaction and the variation in...

Medical records of inpatients discharged from a forensic unit in Columbia, South Carolina, from January 1991 to December 1991 were reviewed to determine the incidence of human immunodeficiency virus (HIV) seropositivity. Results were linked to age, gender, ethnicity, history of intravenous drug use, and Axis I diagnoses. HIV status was obtained for 74 percent of patients 18 to 55 years of age. ...

The effect of cytomegalovirus (CMV) seropositivity on the course of human immunodeficiency virus (HIV) type 1 RNA levels and HIV disease progression was assessed in a cohort of 109 hemophilic men infected with HIV-1 for a median of 12.7 years. There was no evidence of higher HIV RNA levels in the first year after HIV seroconversion (P=. 88) or faster rates of increase over infection (P=.20) in ...

Background: Helicobacter pylori (H.pylori) is a common bacterial infection, with considerably high morbidity and mortality worldwide. This bacterium represents a key factor in the etiology of various chronic infections ranging from gastritis, peptic ulcer disease to gastric cancer; but the prevalence has large variations in different communities. The aim of this study was to estimate the preval...

Following an outbreak of fascioliasis in Anzali Harbor in 1988, 452 blood samples were collected using a multistage sampling method for hematological and serological studies. After determination of eosinophilia in the samples, antifasciolia antibodies in the sera were also determined using enzyme linked immuno sorbant assay (ELISA) and counter-current immuno electrophoresis (CCIE). 64.2% ...

We investigated the route of sexual exposure as a determinant for human papillomavirus (HPV)-16 and HPV-18 seropositivity. At the Amsterdam sexually transmitted infections clinic we recruited 4 risk groups: (1) men who have sex with women only (MSW; n = 751); (2) women who have sex with men (WSM; n = 749); (3) men who have sex with men (MSM) reporting insertive anal sex only (insMSM; n = 156); ...
