Isolation and Identification of Malignant Catarrhal Fever Virus in Cell Cultures
نویسنده
چکیده
Malignant catarrhal fever (MCF) is a fatal disease syndrome responsible for mortality in domestic and wild ruminant species. MCF is caused by gammaherpesviruses – the ovine herpesvirus type 2 causing sheep-associated malignant catarrhal fever (SA-MCF) and alcelaphine herpesvirus type 1 known as wildebeest-associated MCF (WA-MCF). The present study described the cultural peculiarities of MCF virus isolated from different samples originated from dead and alive wild animals from the Sofia Zoo. MDBK, EBTR, RK, MA-104 and VERO cell cultures were used for the isolation of MCF virus. The best growth of viruses was observed on MDBK cell cultures. The CPE was characterised with forming of the syncytium and destruction of the monolayers 2–3 days after the virus adaptation. The CPE was different for obtained isolates. The isolates from gaur formed a bigger cell syncytium than that in the cell cultures infected with buffy coat from bisons where a cell syncytium of smaller size and shape was observed. The virus identification was performed by biochemical methods and PCR.

Abstract Background and Aims: To identify and isolation of viruses a susceptible cell is need which can be primary or line. The use of primary cells is laborious, time consuming and expensive, while the use of cell lines is much easier and faster. IRKHBK cell line was originated from primary cells of bovine kidney by continuous passage. The aim of this study was to introduce the IRKHBK cell ...
