A mutational and genetic analysis of the poliovirus protein 3A has led to the identification of a single amino acid mutant virus with a restrictive phenotype to form plaques in Vero cells. This mutant (I46T 3A) can be grown and amplified in HeLa cells, where virus replication takes place at wild-type levels. However, Vero cells infected with this virus cannot complete the growth cycle. I46T 3A ...
Wild-type measles virus (MV) isolated in B95a cells could be adapted to Vero cells after several blind passages. In this study, we have determined the complete nucleotide sequences of the genomes of the wild type (T11wild) and its Vero cell-adapted (T11Ve-23) MV strain and identified amino acid substitutions R516G, E271K, D439E and G464W (D439E/G464W), N481Y/H495R, and Y187H/L204F in the nucleo...
بیماری(mm) multiple myeloma یکی از جمله سرطان های خون می باشد که بر خلاف بقیه لوسمی ها، سلول های سرطانی (پلاسماسل های سرطانی )کمتر وارد جریان خون میشوند. پلاسما سل های سرطانی بیشتر عواملی را تولید می کنند که این عوامل باعث ایجاد مشکلات جدی در بیماران مبتلا بهmm می شود.. از بین مشکلات مختلف در بیماران مبتلا به mm، افزایش فعالیت استئوکلاست ها و مهار استئوبلاست ها و متعاقب آن پوکی استخوان، شکستگی ...
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...
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...

Vaccination is one of the most effective preventive measures to combat influenza. Prospectively, cell culture-based influenza vaccines play an important role for robust vaccine production in both normal settings and urgent situations, such as during the 2009 pandemic. African green monkey Vero cells are recommended by the World Health Organization as a safe substrate for influenza vaccine produ...
Neospora caninum and Toxoplasma gondii are cyst-forming coccidian parasites of human and veterinary clinical relevance. In vitro cultivation of the protozoans using Vero cells is usually performed in order to produce antigenic materials. Quantitative and qualitative comparisons of Vero cells grown in RPMI medium supplemented either with foetal calf serum (FCS), horse serum (HS) or a specific se...
We report on an optimized method for the in vitro culture of tissue cyst-forming Neospora caninum bradyzoites in Vero cells and the separation of viable parasites from host cells. Treatment of tachyzoite-infected Vero cell cultures with 17 microM sodium nitroprusside for 8 days severely scaled down parasite proliferation, led to reduced expression of tachyzoite surface antigens, and induced the...
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...
