context hepatitis b virus (hbv) and hepatitis c virus (hcv) infections constitute a major global health problem. about 60,000 and 350,000 deaths occur as the results of hbv and hcv infections, respectively. chronic hepatitis b and c infections are leading causes of cirrhosis and hepatocellular carcinoma (hcc) which are considered as the third cancer-associated cause of deaths worldwide. iran su...

Deformed wing virus is an important contributor to honey bee colony losses. Frequently queen failure is reported as a cause for colony loss. Here we examine whether sexual transmission during multiple matings of queens is a possible way of virus infection in queens. In an environment with high prevalence of deformed wing virus, queens (n = 30) were trapped upon their return from natural mating ...

BACKGROUND Little is known about the prevalence of viral infections in children with community-acquired pneumonia (CAP). OBJECTIVES To describe the clinical and virological data collected from children with radiographically confirmed CAP in whom 17 respiratory viruses were sought in respiratory secretion samples during the acute phase of the disease. PATIENTS AND METHODS The study involved ...

Background: Bacterial and viral co-infections are increasingly recognized as the cause of Acute Respiratory Infection (ARI). The role co-infection in ARI patients with Parainfluenza Virus type 3 (PIV3) infection is unclear. Objectives: This study aimed to determine prevalence PIV3 hospitalized children assess co-infections' infections. Methods: Between January 2018 December 2021, were confirmed...

background and aims: herpes simplex virus type 1 (hsv1) remains a potentially serious health problem world wide. all infected people, including asymptomatic ones, are potential sources for virus transmission. virus envelope contains at least 13 glycoproteins, which glycoprotein d is the major target of immune responses. the aim of this study was development of a specific method that is a more r...

     The influenza viruses are major etiologic agents of human respiratory infections, and inflict a sizable health and economic burden. This study examines the antiinfluenza virus activity of hydroalcoholic extract of olive leaves (OLHE). Olive leaves were collected from gardens around the city of Shiraz, characterized, dried, ground to powder, and its hydroalcoholic extract was prepared. The ...

An adenovirus 5 vector encoding for mouse interferon alpha, subtype 5 (mDEF201) was evaluated for efficacy against lethal cowpox (Brighton strain) and vaccinia (WR strain) virus respiratory and systemic infections in mice. Two routes of mDEF201 administration were used, nasal sinus (5-µl) and pulmonary (50-µl), to compare differences in efficacy, since the preferred treatment of humans would be...

conclusions although the dentists had a proper knowledge in the field of transmission of hiv, hbv, and hcv infections, fear and concern of being infected make them to refuse these patients. therefore, training dentists to improve their attitudes toward treatment of these patients is necessary. background dental practitioners can be exposed to the human immunodeficiency virus (hiv), hepatitis b ...

Cross-reactive T cell responses induced by a primary dengue virus infection may contribute to increased disease severity following heterologous infections with a different virus serotype in a phenomenon known as the original antigenic sin. In this study, we developed and analyzed in-host models of T cell responses to primary and secondary dengue virus infections that considered the effect of T ...

Infections with hepatitis viruses are known to be prevalent in sub-Saharan Africa but in Benin, data on these infections are still scarce. The study was carried out to assess the burden of these infections in Cotonou. From June to October 2016, we conducted a cross-sectional study on 156 Hepatitis B Virus (HBV) infected patients attending the University Teaching Hospital and a private hospital ...
