Cholesteryl 3",4"-dimethoxycinnamate (7) and a new synthesized o-coumaroyl ester of 3 beta-(2'-hydroxyethoxy)-cholest-5-en (13) exhibited a marked activity against poliovirus type 1 (Mahoney). Compound 7 showed an approximately 20-fold greater selectivity in its antiviral activity than compound 13. These compounds were selected from thirteen steryl esters of cinnamic acid derivatives through an...

Peste des petits ruminants (PPR) is a highly contagious and economically important disease of small ruminants caused by a virus in the genus morbillivirus, family paramyxoviridae. This infection is responsible for high morbidity and mortality. In this study, an outbreak of PPR in goats was investigated in a well organized farm at district Lahore. Clinical signs, gross lesions and histopathologi...

Respiratory syncytial virus (RSV) and pneumonia virus of mice (PVM) are viruses of the family Paramyxoviridae, subfamily pneumovirus, which cause clinically important respiratory infections in humans and rodents, respectively. The respiratory epithelial target cells respond to viral infection with specific alterations in gene expression, including production of chemoattractant cytokines, adhesi...

We isolated an apparently new virus in the family Paramyxoviridae from stillborn piglets with deformities at a piggery in New South Wales, Australia. In 1997, the pregnancy rate and litter size at the piggery decreased markedly, while the proportion of mummified fetuses increased. We found serologic evidence of infection in pigs at the affected piggery and two associated piggeries, in humans ex...

Peste des petits ruminants (PPR) is a highly infectious and economically important, viral disease of small caused by the peste virus (PPRV), which belongs to genus Morbilivirus in family Paramyxoviridae. PPR control mostly achieved through vaccination and/or slaughter susceptible animals coupled with clinical or laboratory-based diagnosis. The eventual eradication now one top priorities for Foo...

Human respiratory syncytial virus (hRSV) is an enveloped RNA virus that belongs to Paramyxoviridae family. HRSV is the most common cause of bronchiolitis and pneumonia in young children in the United States, and severe infections of infants and immuno-compromised adults can lead to death. In order to characterize the molecular mechanisms underlying hRSV assembly and viral and host cellular prot...

Abstract Respiratory syncytial virus (RSV) is an RNA that belongs to the Pneumovirus genus of Paramyxoviridae family. The aim this study was evaluate expressions inducible nitric oxide synthetase (iNOS), CD3 (pan T cells), and CD8 (cytotoxic cells) in lamb lungs naturally infected with RSV using immunohistochemistry (IHC). For purpose, 100 pneumonic 10 control lung tissue samples were taken fro...

Matrix (M) gene sequences for recent field isolates and older reference Newcastle disease viruses (NDV) were examined to determine phylogenetic relationships and population trends among these viruses. Overall, the M gene has a majority of synonymous nucleotide sequence substitutions occurring among NDV isolates. However, several predicted amino acid changes in the M protein of specific NDV isol...

We have defined the expression of the mRNA for, and secretion of, IFN-beta 2/hepatocyte-stimulating factor/IL-6 (IFN-beta 2/IL-6) in human diploid fibroblasts (FS-4 strain) infected with different RNA- and DNA-containing viruses. RNA blot-hybridization analyses carried out 6-8 h after the beginning of infection showed that the RNA-containing Sendai virus (paramyxoviridae) enhanced IFN-beta 2/IL...
