Human Herpes Viruses (HSV) contain eight pathogens. HSV is one of the most widespread viruses in the world and due to the simplicity of the way of transmission the number of people infected with the virus has increased in per year. The virus creates a wide range of diseases, including mucosal herpes infections and deadly herpes simplex encephalitis. Today, for the diagnosis of HSV infection se...
herpes simplex virus type 1 (hsv-1) with a worldwide distribution has been reported in all human populations, resulting in a clinical spectrum of infections. although hsv type 2 (hsv-2) is known as the most common cause of genital herpes, an increasing number of cases with genital herpes are caused by hsv-1. the present study aimed to discuss the changes in the epidemiology of hsv-1 infection i...
Seroprevalence of some bovine viral respiratory diseases among non vaccinated cattle in Saudi Arabia
Aim: Four viral pathogens, bovine viral diarrhea virus (BVDV), and bovine herpes virus type 1 (BHV-1), bovine parainfluenza type 3 virus (PI-3V), bovine respiratory syncytial virus (BRSV) are mainly associated with bovine respiratory diseases that cause major economic losses in the dairy cattle industry. This study aimed to document exposure of cattle in Saudi Arabia to infectious BVDV, BHV-1, ...
the measurement of antibody responses of animals exposed to bvdv either through a natural exposure or an immunization protocol is still a standard procedure. for bvdv, the test formats have been largely limited to elisa which is a valuable diagnostic test to measure the level of bvdv specific antibodies as well as antigen in blood samples. in the present study, 120 blood samples were collected ...
conclusions herpes simplex virus was present in more patients with ms than healthy cases. hsv may be directly or indirectly associated with ms development. further comprehensive molecular studies are needed to confirm the etiopathologic association between hsv and ms disease. results totally, 63 (76.8%) patients with ms showed a history of hsv exposure by anti-hsv testing compared to 70 (78.7%)...
background :wide distribution and low half-life of acyclovir has led to a high dose consumption of the drug. recent studies have shown that encapsulation of acyclovir in nano-carriers can increase effectiveness and decrease its side effects. we investigated the inhibitory effect of acyclovir loaded nano-niosomes against herpes simplex virus type-1 (hsv-1) in cell culture. methods : in-vitro c...
The virus specificity of antibodies against bovine herpes virus type 1 was determined with a radioimmunoprecipitation assay and serum collected from natural and experimentally induced infections. By using sequentially collected sera, the development of antibodies to 4 to 5 viral glycoproteins and 11 to 12 nonglycosylated proteins was followed for the first 50 days after infection. The major and...
Brown alga, Turbinaria conoides was successively extracted with n-hexane, cyclohexane, methanol and ethanol:water (1:1). The extracts were evaluated for antibacterial and antifungal activities by disc diffusion method. Minimal inhibitory concentration was determined for active extracts by broth dilution method. The antiviral activity and cytotoxicity of the extracts were tested in human embryon...
