One of the greatest causes of loss in the food industry is postharvest diseases of fruits and vegetables (Vero Mendez & Mondino, 1999). According to U.S.A. estimations this loss reaches 20 25% whereas in developing countries the losses are often more severe due to inadequate storage and transportation facilities (Sharma et al., 2009), but loss has generally been considered to be approximately 1...

Canine distemper virus (CDV) infections cause high morbidity and mortality in dogs. Changes the molecular biological characteristics of Korean CDV strain over multiple cell passages have not been reported. We investigated genetic CD1901-100 for use as an inactivated vaccine strain. Vero cells expressing dog nectin-4 gene (Vero/dNectin-4 cells) were used to adapt CD1901, which was passaged 100 t...

The ribonucleotide reductase (RR) 2 gene of the HSV-2 strain G was cloned, sequenced, and expressed in an E. coli cell. The RR2 gene was located on the PstI 2.4 kb fragment, which was cloned and sequenced. The ORF of the gene was 1,011 bp and its termination codon was TAG; also, the CATATAA sequence was present in the promoter of the RR2 gene. A Poly A signal sequence (AATAAA) was found in the ...

Persistent viral infections can render host cells resistant to superinfection with closely related viruses by largely uncharacterized mechanisms. We present evidence for superinfection exclusion in brains of Borna disease virus (BDV)-infected rats and in persistently infected Vero cells, and we suggest that acquired resistance to BDV is due to unbalanced intracellular levels of viral nucleocaps...

Measles has a host range restricted to humans and monkeys in captivity. Fresh measles virus (MV) isolates replicate readily in several human and simian B-cell lines but need a period of adaptation to other types of cells. The identification of CD46 and CD150 (SLAM) as cellular receptors for MV has helped to clarify certain aspects of the immunobiology of MV infections. We have examined the prop...

The purpose of this study was to investigate the effect of curcumin-treated Herpes simplex virus-1 (HSV-1) and Herpes simplex virus-2 (HSV-2) virions in cultured Vero cells. Previous studies have indicated that curcumin, a polyphenol extracted from the plant Curcuma longa, has demonstrated antiviral properties against a variety of viruses. After establishing the maximum non-cytotoxic concentrat...

Twenty four sera from patients with haemolytic uraemic syndrome or haemorrhagic colitis and healthy controls were examined for antibodies to the lipopolysaccharide (LPS) of Escherichia coli O157. Faecal specimens from these patients were also examined for Vero cytotoxin producing E coli (VTEC) by DNA probes, and for faecal Vero cytotoxin. Eight patients with faecal E coli O157:H7 gave a strong ...

The aim of this study was to determine the inhibitory action of alantolactone, a gradient of traditional Chinese medicine Inulae Radix (Tu-Mu-Xiang), on herpes simplex virus 1 (HSV-1). African green monkey kidney cells (Vero cells) were infected with HSV-1 and the protective effects of alantolactone on Vero cells were examined. At concentrations of 10(-6), 10(-7), and 10(-8) g/mL, alantolactone...

During the recent severe acute respiratory (SARS) outbreak, the etiologic agent was identified as a new coronavirus (CoV). We have isolated a SARS-associated CoV (SARS-CoV) strain by injecting Vero cells with a sputum specimen from an Italian patient affected by a severe pneumonia; the patient traveled from Vietnam to Italy in March 2003. Ultrastructural analysis of infected Vero cells showed t...
