Clinical isolates of measles virus (MV) use signaling lymphocyte activation molecule (SLAM) as a cellular receptor, whereas vaccine and laboratory strains may utilize the ubiquitously expressed CD46 as an additional receptor. MVs also infect, albeit inefficiently, SLAM(-) cells, via a SLAM- and CD46-independent pathway. Our previous study with recombinant chimeric viruses revealed that not only...

BACKGROUND Morphological changes of the cells infected with rubella virus cannot be observed easily. Estimation of the size of the cultured cells can be a valuable parameter in this condition. This study was conducted to find answers to the following questions: How much time after infection with rubella virus, the volume and surface area of the Vero cells and their nuclei get started to change?...

Mouse fibroblasts (L-929) and Vero (green monkey kidney) cells were infected with the rickettsia Coxiella burnetti, and persistent infections developed and were studied over a 6- to 10-month period. Ultrastructural comparisons were made between the two infected cell types, and both were tested cytochemically for the presence of acid phosphatase, a marker enzyme of lysozymes. Rickettsiae were al...

BACKGROUND Glycolipids are one component of cell membranes, and are found most prevalently at the surface of the plasma membrane. Animal cells take in amphipathic glycosides, which are later glycosylated after assimilation in biosynthetic pathways. Gycosylated glycosides are released outside of cells to the surrounding culture medium. This represents an accessible method of obtaining complex gl...

Current egg-based influenza vaccine production technology can't promptly meet the global demand during an influenza pandemic as shown in the 2009 H1N1 pandemic. Moreover, its manufacturing capacity would be vulnerable during pandemics caused by highly pathogenic avian influenza viruses. Therefore, vaccine production using mammalian cell technology is becoming attractive. Current influenza H5N1 ...

Attachment and invasion of Toxoplasma gondii and Neospora caninum to a cat and a dog fibroblast cell line and 2 epithelial cell lines (a cat kidney and Vero) were compared in vitro using fluorescence antibody methodology. In addition, trypsin treatment of tachyzoites was used to determine whether protein molecules were essential to the process of invasion. The results show that both T. gondii a...

BACKGROUND Portulaca oleracea Linn. (Portulacaceae) is commonly known as purslane in English. In traditional system it is used to cure diarrhea, dysentery, leprosy, ulcers, asthma, and piles, reduce small tumors and inflammations. AIM To assess cytotoxic potential of chloroform extract of P. oleracea whole plant against human colon adenocarcinoma (HCT-15) and normal (Vero) cell line. MATERI...

In this preliminary study we investigate for the first time the biomedical potential of using porous anodic aluminium oxide (AAO) membranes as a cell substrate for culturing the Cercopithecus aethiops (African green monkey) Kidney (Vero) epithelial cell line. One advantage of using the inorganic AAO membrane is the presence of nanometre scale pore channels that allow the exchange of molecules a...

Abstract Porcine epidemic diarrhoea virus (PEDV) is one of the major pathogens causing acute enteritis, which characterised by vomiting and watery commonly leads to high rates mortality morbidity in suckling piglets. Chitosan has been regarded as a promising natural disinfectant. In this study, disinfectant effect mammalian-cell toxicity chitosan were evaluated against PEDV using Vero cells. A ...

The aim of this study is to prepare a model for the production of Newcastle disease virus (NDV) lentogenic F strain using cell culture in bioreactor for live attenuated vaccine preparation. In this study, firstly we investigated the growth of Vero cells in several culture media. The maximum cell number was yielded by culture of Vero cells in Dulbecco's Modified Eagle Medium (DMEM) which was 1.9...
