BACKGROUND Chlamydia pneumoniae is an obligate intracellular respiratory pathogen capable of persistent infection. Seroepidemiologic studies and the results of open-label antimicrobial treatment of patients with non-steroid-dependent asthma have suggested a potential role for C. pneumoniae in asthma. OBJECTIVE To evaluate the results of antimicrobial treatment in patients with uncontrolled st...

For the first time in Iran, a number of 1736 sera samples of wild pigeons which were collected from different parts at Tehran, were investigated to determine the specific antiornithosis antibody using complement fixation test. In this study, 26,5 percent of samples represented ornithosis. 

Many epidemics of water-borne hepatitis have occurred throughout India. These were thought to be epidemics of hepatitis A until 1980, when evidence for an enterically transmitted non-A, non-B hepatitis was first reported. Subsequently, hepatitis E virus was discovered and most recent epidemics of enterically transmitted non-A, non-B hepatitis have been attributed to hepatitis E virus infection....

A nationwide community-based survey for Helicobacter pylori infection had not been done. This study sought to determine the seroprevalence of infection in Mexico, and the socioeconomic and demographic variables that are risk factors for infection. The survey assessed 11,605 sera from a sample population representing persons ages 1-90 years from all socioeconomic and demographic levels and from ...

With improvements in management of acute rejection and allograft function over the past decades, short-term survival after solid-organ transplantation is excellent, and death with a functioning graft has become the outcome for the majority of solid-organ transplant recipients. Thus, there is a necessity to focus not only on interventions to maintain graft function, but also to address other pos...

This cross-sectional study was carried out between August 2011 and July 2012 in the city of Campos dos Goytacazes in Rio de Janeiro State, Brazil. Dried blood spot samples were collected on filter paper from 919 individuals between the ages of 1 and 19 and were tested for antibodies against the hepatitis A virus (anti-HAV). The total prevalence was 20.7%, while 94.7% of children under the age o...

Human infection by leptospires has highly variable clinical manifestations, which range from subclinical infection to fulminant disease. We conducted a population-based, cross-sectional seroepidemiologic study in Peru to determine potential relationships of environmental context to human exposure to Leptospira and disease associated with seroconversion. Three areas were studied: a flooded, urba...

A combined cell culture enzyme-linked immunosorbent assay (CCC-ELISA) was developed for measuring the neutralizing antipoliovirus antibodies in human sera. The binding of different concentrations of each of the three poliovirus types to BGM cells in the presence and absence of a constant dilution from each test and reference serum was measured in the CCC-ELISA. The titers of the viruses neutral...
