La maladie de Still de l'adulte (MSA) est une maladie inflammatoire rare d'étiopathogénie mal élucidée qui se manifeste par une fièvre associée à des arthrites, une éruption cutanée fugace et des atteintes multi-viscérales. Elle se complique rarement d'une hépatite fulminante qui aggrave le pronostic. Patiente âgée de 38 ans admise pour une fièvre prolongée associée à des arthralgies de type in...

The antiviral effects of bovine interferons on the replication of bovine respiratory tract viruses were studied. Bovine turbinate monolayer cultures were treated with bovine interferons and challenged with several bovine herpesvirus 1 strains, bovine viral diarrhea virus, parainfluenza type 3 virus, goat respiratory syncytial virus, bovine respiratory syncytial virus, bovine adenovirus type 7, ...

Eight calves between 16 and 18 weeks of age that were seronegative to bovine viral diarrhea virus (BVDV), bovine leucosis virus and bovine immunodeficiency-like virus were infected (day 0) intranasally with the type 2 noncytopathogenic Canadian 24515 field isolate of BVDV in order to evaluate the effect of BVDV infection on certain clinical, hematological and immunological parameters. All virus...

BACKGROUND: Q fever is a zoonotic disease caused byCoxiella burnetii, a species of bacteria that is distributedworldwide. In cattle, Coxiella burnetii infections are generallyasymptomatic but can also be associated with reproductivedisorders. OBJECTIVES: The aim of this study was to achievemolecular detection of Coxiella burnetii in dairy bovine milkfarms using Nested PCR in Qom province, Iran....

a total of 1,497 serum and blood specimens from residents of 18 different iranian communities were examined by plaque reduction neutralization test for antibodies against four (neaples, sicilian, karimabad and salehabad) phlebotomus fever virus serotypes. neutralizing antibodies against the naples and sicilian serotypes were found in every community sampled, indicating that these viruses are wi...

Classical swine fever virus (CSFV) E2 glycoprotein contains a discrete epitope (TAVSPTTLR, residues 829-837 of CSFV polyprotein) recognized by monoclonal antibody (mAb) WH303, used to differentiate CSFV from related ruminant pestiviruses, Bovine Viral Diarrhea Virus (BVDV) and Border Disease Virus (BDV), that infect swine without causing disease. Progressive mutations were introduced into mAb W...

This review deals with the role of viruses in the aetiology of bovine mastitis. Bovine herpesvirus 1, bovine herpesvirus 4, foot-and-mouth disease virus, and parainfluenza 3 virus have been isolated from milk from cows with clinical mastitis. Intramammary inoculations of bovine herpesvirus 1 or parainfluenza 3 virus-induced clinical mastitis, while an intramammary inoculation of foot-and-mouth ...

Virus Diseases Many of the parasitic, nutritional and, to some extent, infectious diseases of cattle have been known for years and are readily handled by proper use of antibiotics and addition of minerals and vitamins to the ration. Recent studies indicate that 65 percent of the feedlots sampled in one state were infected with para influenza 3 virus ( the virus involved in shipping fever } . An...

bovine leukosis virus (blv) is a retrovirus that primarily affects lymphoid tissue of cattle. to determine the seroprevalence of enzootic bovine leukosis virus infection and its effects on some clinical, hematological and flow cytometric indications, this study was conducted on 197 holstein cattle slaughtered in an abattoir in tehran province. elisa gp51 test of the obtained serums of the anima...
