Three hundred and forty serum samples collected from women of child bearing age, without any clinical evidence of cytomegalovirus (CMV) infection, were screened for the presence of IgG antibodies against CMV by ELISA test. The IgG antibodies were detected in 297 which gave prevalence rate of 87.4%. Significantly higher prevalence rates (p < 0.001) were observed with increasing age and with incr...
INTRODUCTION Leptospirosis is endemic to tropical regions of the world and is re-emerging as a new danger to public health in Malaysia. the purpose of this particular study was to determine the common leptospiral serovars present in human communities living around wildlife reserves/disturbed forest habitats. the objective of this study was to estimate the seroprevalence of leptospirosis and fin...
Background and Objectives Q fever is a zoonotic disease and farm animals serve as the main reservoir of the disease. The aim of this study was to evaluate the seroprevalence of Q fever in sheep, in Lorestan province in western Iran. Materials and Methods In this cross-sectional study, 330 blood samples were collected from sheep, from each county in Lorestan province. The samples were tested b...
Visceral leishmaniasis (VL) is endemic in parts of Islamic Republic of Iran. A cross-sectional seroprevalence study was carried out in children in Booyerahmad district in the south-west of the country. Serum samples were taken from 1628 children up to 10 years old from different areas in Booyerahmad in 2005-06. AntiLeishmania antibody was detected in 50 out of 1628 children (3.1%) by direct agg...
The pattern of epidemic meningococcal disease in the African meningitis belt may be influenced by the background level of population immunity but this has been measured infrequently. A standardised enzyme-linked immunosorbent assay (ELISA) for measuring meningococcal serogroup A IgG antibodies was established at five centres within the meningitis belt. Antibody concentrations were then measured...
Epilepsy is one of the most common neurologic disorders. Underlying cause of epilepsy is unknown in 60 % of the patients. Toxoplasma gondii is an intracellular parasite which is capable of forming tissue cysts in brain of chronically infected hosts including humans. Some epidemiological studies suggested an association between toxoplasmosis and acquisition of epilepsy. In this study we determin...
AIM Toxoplasma gondii is an ubiquitous apicomplexan parasite which causes toxoplasmosis in humans and animals. Felids especially cats are definitive hosts and almost all warm-blooded mammals, including livestock and human can serve as intermediate hosts. Food animals can be reservoirs for T. gondii and act as one of the sources for parasite transmission to humans. The objective of this study is...
Atherosclerosis is a chronic inflammatory disease. It still the leading cause of mortality and morbidity in world. Inflammation vessels plays most important role pathogenesis atherosclerosis. Many studies have been emphasized that Chlamydia pneumoniae triggers inflammation associated with stated chlamydial infections are asymptomatic around 40% adult individuals infected. has different subgroup...
BACKGROUND Toxocariasis is the clinical terms applied to infection of human with Ascarid nematodes in the order Ascaridida, named Toxocara canis and T. cati. Because in recent years in Iran many people desire to keep pets (cats and dogs), and lacking of seroepidemiological study of toxocariasis in Mashhad, we decided to determine the seroprevalence of toxocariasis among people who own cats and ...
BACKGROUND Little is known about HEV seroprevalence and its determinants in Iran. Considering the fact that Iran is among the countries in which HEV infection is endemic, a large-scale population-based study in this regard is justified. METHODS This survey was conducted in 2006 in Tehran and Golestan Provinces, Iran. Stored sera of subjects were tested for serological markers of anti-HEV. The b...
