The aim of this study was to identify the cell surface cluster of differentiation (CD) markers of the cell lines infected by Theileria annulata schizont. The CD molecules are very useful for the characterization of cells and different subpopulations of leukocytes. They are usually recognized by specific antibodies using flow cytometry and immunohistochemistry. In the current stud...

Background: It was shown that olive leave extract has antifungal, antibacterial and antiviral activities. The effects of OLE on herpes simplex virus-1 (HSV-1) have not been systematically investigated yet. The aim of this study was to examine the in vitro effect of olive leaf hydroalcoholic extract (OLHE) on HSV-1. Methods: Virucidal effect and viral replication in Vero cell line were studied i...

BACKGROUND Current knowledge of the consistency of protection induced by seasonal influenza vaccines over the duration of a full influenza season is limited, and little is known about the clinical course of disease in individuals who become infected despite vaccination. METHODS Data from a randomized double-blind placebo-controlled clinical trial undertaken in healthy young adults in the 2008...

Adenoviruses are common pathogens. The localization of their receptors coxsackievirus and adenovirus receptor, and desmoglein-2 in cell-cell junction complexes between polarized epithelial cells represents a major challenge for adenovirus infection from the apical surface. Structural proteins including hexon, penton base and fiber are excessively produced in serotype 5 adenovirus (Ad5)-infected...

BACKGROUND Hepatitis C virus (HCV) infection afflicts about 170 million individuals worldwide. However, the HCV life cycle is only partially understood because it has not been possible to infect normal human hepatocytes in culture. The current Huh-7 systems use cloned, synthetic HCV RNA expressed in hepatocellular carcinoma cells to produce virions, but these cells cannot be infected with natur...

Lymphocytic choriomeningitis (LCM) virus-infected culture cells as targets were markedly reduced in numbers when incubated in vitro with spleen cells from LCM virus-immune mice, even if the cells were taken months after a subcutaneous immunizing infection of the donor animal. Spleen cells from mice persistently infected with LCM virus had no effect on target cells. Also, mitomycin C-blocked LCM...

background: chlamydia trachomatis is the most reported bacterial sexually transmitted disease, especially among young women worldwide. aim of this study was comparison to evaluate the prevalence of chlamydia trachomatis infection in woman with tubal infertility by means of pcr and cell culture techniques. methods: fifty-one women with confirmed tfi were enrolled in this study in (avicenna infer...

Ovine lentiviruses and caprine arthritis-encephalitis virus (CAEV) are prototypic lentiviruses that replicate predominantly in macrophages of infected animals. In situ hybridization of pathologically affected tissues from diseased animals has shown that viral RNA exists in permissive macrophages as well as in non-macrophage cell types that do not support productive virus replication. These find...

In order to investigate hepatitis C virus (HCV) persistence and replication in peripheral blood mononuclear cells (PBMC) from a group of haemophilic individuals, HCV production and release to PBMC culture supernatants (SNs) from HCV singly infected patients and HIV/HCV co-infected patients was studied. HCV RNA+ SNs were found more frequently from HIV/HCV co-infected individuals (89.5 %) with po...

pseudomembrane colitis (pmc) and antibiotic associated colitis (aac) are acute disease of the colon. in the case of in adequate treatment, the disease will often become chronic and my lead to the dysplasia of the epithelial cells of the infected areas. previously because of poor knowledge. treatment in this case, one of the method for treatment was surgical ablation of the large intestine while...
