Abstract Introduction/Objective There exists contradictory evidence in the literature that ABO blood group may have some impact on risk of COVID-19 infection. Some argue A confer a higher susceptibility to infection and thus be overrepresented those who test positive for COVID-19, though other studies do not support this. Therefore, we present regional Veterans Administration Medical Center’s (...

Objective(s):Helicobacter pylori infection occurs worldwide, but the prevalence of this infection varies greatly among different countries and population groups. The aim of this study was to determine the seroprevalence of anti-Helicobacter pylori and anti-cytotoxin-associated gene A (CagA) antibodies in asymptomatic healthy population in the center of Iran and to investigate the relation with ...

conclusions the diagnostics and management of infections with hepatotropic viruses, particularly hbv, are neglected in hemophilic patients. all patients with coagulation disorders and a history of exposure to non-inactivated blood products should be screened for blood-borne infections. the prevalence of other potentially blood-borne viral infections exhibited a pattern similar to that observed ...

The canine heartworm, Dirofilaria immitis, is among the most important parasites of dogs in United States and worldwide, may cause severe potentially fatal disease. Current diagnostic recommendations rely on serological detection an adult female antigen, visualization microfilariae blood. Therefore, a reliable diagnosis can be only performed approximately six months post-infection. There growin...

background and objectives: the aim of this study was to compare direct microscopic examination with culture and pcr for the diagnosis of mucorales infection in blood and tissue specimens. material and methods: blood samples and tissue specimens were obtained from 28 patients (total 58 samples) with suspected invasive fungal infection and cultured on proper media. direct smear of tissue samples ...

introduction : one of  the most common ways of hiv transmission is from blood products. hiv infection causes immuno-deficiency in human, and consequently increases the rate of mortality and morbidity. thalassemic patients, because of severe anemia, need  blood transfusion. therefore the rate of contamination with hiv increases. the aim of this study is to invesitigate the frequency of hiv infec...

Background: In 1997, a novel DNA virus was isolated from the serum of a patient in Japan, and it was named TT virus (TTV). As the virus is replicated in liver and has the ability to induce apoptosis in hepatocytes (Hepatocellular carcinoma cells) it is hypothesized that TTV is an opportunistic virus and in certain conditions causes liver damage. In this study the frequency of infection with TTV...
