Ten recent isolates of canine distemper virus (CDV) strains were classified according to the growth ability and development of syncytial cytopathic effects (CPE) in Vero cells. Strains P94S, Ac96I, S124C, MD231, MS232, MSA5 and 095Cr were classified as Type 1 and exhibited hardly and did not develop CPE in Vero cells. Strains 007Lm, 009L and 011C were classified as Type 2 as grew well but faile...

Diphtheria toxin has the capacity to block protein synthesis in cultured mammalian cells, and thus causing cell death. This capacity of diphtheria toxin was utilized for in-vitro neutralization test to determine antibody titer, using Vero cells, which have been found to be susceptible to diphtheria toxin. In the present study, a Vero cell assay was standardized and validated for potency estimat...

The role of the cell nucleus in the development of African swine fever virus in Vero cells has been studied. No viral growth could be detected in enucleated cells under conditions that allow normal development of Sindbis virus. Furthermore, African swine fever virus DNA synthesis was inhibited more than 95% after infection of enucleated Vero cells as compared with normal cells.

Cell culture requires a suitable medium and environment for in vivo conditions. Conditions are created by regulating temperature, pH, oxygen, CO2, osmotic pressure, surfaces to adhere cells, nutrients, vitamins, protection against toxic substances, hormones, growth factors that regulate cell differentiation. In general, good occurs at pH of 7.0 - 7.6. Fetal Bovine Serum (FBS) is one the supplem...

The role of antibiotics in the treatment of Shiga-like toxin (Stx)-producing E. coli infection is still controversial. This study investigated the effects of colistin on Vero cell cytotoxicity caused by the enterohemorrhagic EC O157:H7, and the effects of colistin on Stx and endotoxin release by EC O157:H7. Vero cells were incubated with supernatant collected from EC O157:H7 cultured for 18 h w...

enterohemorrhagic escherichia coli (ehec), such as e. coli o157:h7, are emerging food-borne pathogens worldwide. this micro-organism can damage the epithelial tissue of the large intestine. the cytotoxic effects can be neutralized by probiotics such as bifidobacterium bifidum. probiotics are viable cells that have beneficial effects on the health of the host. the preventing activity of b. bifid...

Continuous cell lines that originate from mammalian tissues serve as not only invaluable tools for life sciences, but also important animal cell substrates for the production of various types of biological pharmaceuticals. Vero cells are susceptible to various types of microbes and toxins and have widely contributed to not only microbiology, but also the production of vaccines for human use. We...

Clostridium perfringens iota-toxin consists of two separate proteins identified as a cell binding protein, iota b (Ib), which forms high-molecular-weight complexes on cells generating Na(+)/K(+)-permeable pores through which iota a (Ia), an ADP-ribosyltransferase, presumably enters the cytosol. Identity of the cell receptor and membrane domains involved in Ib binding, oligomer formation, and in...
