Multiple cell lines permissive to nervous necrosis virus (NNV) infection may be necessary for identifying receptor binding sites of viral surface protrusions. ​We have established new lines, SeGE-12, SeGE-22, SeGF and SeGB, derived from eyed-egg embryos, fin brain sevenband grouper. ​The optimum growth temperatures these were all around 30°C. temperature range SeGE-12 SeGE-22 was 25°C–32°C, whe...

N(1)-isonicotinoyl-N(2)-3-methyl-4-chlorobenzoylhydrazine (IMCBH) is a selective inhibitor of vaccinia virus multiplication. In concentrations up to 50 microg/ml, IMCBH causes neither toxic morphologic changes, nor does it inhibit the multiplication of cells. Viruses other than vaccinia are not affected by IMCBH. The virus-inhibitory effect of IMCBH is dependent on the type of host cell used, i...

The prognosis of gastric cancer patients with peritoneal dissemination is extremely poor, and the development of an effective treatment is necessary. The aim of this study was to investigate the efficacy of oncolytic reovirus against peritoneal metastasis in human gastric cancer using an experimental animal model. Four human gastric cancer cell lines, including MKN45p, NUGC4, MKN7 and KatoIII, ...

OBJECTIVE To investigate antiviral activity of maca to reduce viral load in Madin-Darby canine kidney (MDCK) cells infected with influenza type A and B viruses (Flu-A and Flu-B, respectively). METHODS Maca were extracted with methanol (1:2, v/v). The cell viability and toxicity of the extracts were evaluated on MDCK cells using method MTT assay. Antiviral activity of compounds against Flu-A a...

Background: Avipox virus considered to be a contagious disease of many types of birds wild and domestic. The current study focused on the isolation of recently common Avipox virus which include fowl pox (FP) and pigeon pox (PP) viruses in Iraq. Materials & methods: Isolation of the viruses was done via chorioallantoic membrane (CAM) route of avian embryo inoculation, also used by a chicken fibr...

BACKGROUND & OBJECTIVES Aeromonas spp. are known to cause a variety of infections in humans and this organism has been isolated from a variety of sources including environmental sources. The pathogenicity of the environmental isolates in and around Vellore has not been studied. This study was conducted to determine the cytotoxicity of the Aeromonas spp. isolated from water bodies, soil sediment...

Recent clinical reports indicate that infection with dengue virus (DENV) commonly has ocular manifestations. The most serious threat to vision is dengue retinopathy, including retinal vasculopathy and macular edema. Mechanisms of retinopathy are unstudied, but observations in patients implicate retinal pigment epithelial cells and retinal endothelial cells. Human retinal cells were inoculated w...

Chronic Hepatitis C Virus (HCV) infection is associated with progressive liver injury and subsequent development of fibrosis and cirrhosis. The death of hepatocytes results in the release of cytokines that induce inflammatory and fibrotic responses. The mechanism of liver damage is still under investigation but both apoptosis and immune-mediated processes may play roles. By observing the change...

Influenza virus causes high morbidity among the infected population annually and occasionally the spread of pandemics. Melaleuca alternifolia Concentrate (MAC) is an essential oil derived from a native Australian tea tree. Our aim was to investigate whether MAC has any in vitro inhibitory effect on influenza virus infection and what mechanism does the MAC use to fight the virus infection. In th...
