equine babesiosis is a hemoprotozoan tickborne disease with worldwide distribution and caused by theileria equi and babesia caballi. this study was conducted to determine the seroprevalence of t. equi and b. caballi infection in turkoman breed horses in north khorasan province of iran. blood samples were collected from 100 apparently healthy horses and examined by microscopy and indirect immuno...
Background: Hepatitis type C virus (HCV) is one of the important threatened infectious blood born viruses in different populations. More than 300 million people were suffered form different HCV clinical complications all around the world. It is estimated that only 20% of HCV infected individuals will recover from this viral infection, while the rest become chronically infected. The majority of ...
Determination of the frequency of bacteria isolated from blood culture and the pattern of their antibiotic sensitivity is epidemiologically of great importance and can help choosing primary antimicrobial treatment. The aim of the current study was to determine the most common bacterial factors of blood infection and their antibiotic sensitivity in a one year period from October 2010 till the en...
Introduction: Human cytomegalovirus (HCMV) infection is most often asymptomatic in immuno-competent individuals and has lifelong latency especially in leukocytes. However, CMV is a major cause of infection and death in immuno-compromised patients. Transfusion transmitted HCMV (TT-HCMV) can cause serious morbidity and mortality in certain patients who are at risk. In this study, we evaluated t...
Background and Aims: Viral hepatitis is a global health problem with a high mortality rate. Recently, a new Flavi-like virus, provisionally named hepatitis G virus (HGV), has been described. HGV does not induce an immune response that is consistently detectable by using recombinant proteins from prokaryotic expression, therefore studies have been conducted by using polymerase chain reaction (...
Equine piroplasmosis is a tickborne disease of equids with worldwide distribution, caused by Theileria equi and Babesia caballi. The aim of this study was molecular detection of T. equi and B. caballi in donkeys in northeastern Iran and investigate the association between positivity of piroplasm infection and host-related factors. In the present study, Blood samples were collected from 106 appa...
Background & Objective: Coronavirus disease 2019 (COVID-19) is the most recent emerging viral disease. Defining the epidemiological aspects and factors influencing the susceptibility of the patients to COVID-19 has been an ongoing struggle. In the present study, we have investigated the connection between ABO histo-blood group phenotypes and the COVID-19. Methods:...
Background: Hepatitis B is the most common blood-borne viral infection that is considered as a major public health problem of the world's major health problems. The aim of this study was to investigate the prevalence of hepatitis B virus (HBV) infection among blood donors referring to blood transfusion centers. Methods: This retrospective cross-sectional study was performed on 216004 volunteer...
diagnosis of hepatitis b is routinely based on of serological assay of hepatitis b surface antigen (hbsag). occult hepatitis b virus (hbv) infection is generally defined as the detection of hbv -dna in the serum or tissues of subjects who have negative test for hbsag. transmission of hbv infection has been documented from hbsag negative, anti-hbc positive blood and organ donors. the aim of this...
Background and Objective: Cytomegalovirus (CMV), one of the most common opportunistic pathogens in patients infected with human immunodeficiency virus (HIV), can cause the diseases such as encephalitis, pneumonia, and chorioretinitis. This study aimed at molecular studying of CMV infection in individuals infected with the human immunodeficiency virus. Material and Methods: In this study, 50 ven...
