Determining the Duration of Maternal Immunity Against Sheep Pox in Lambs.

Maternal immunity may affect vaccination success in young lambs. This study was aimed to determine the duration of the maternal immunity in lambs born from vaccinated ewe against Sheep pox. The level of neutralizing antibody against Sheeppox virus (SPPV) was measured in 14 lambs that were fed colostrum of their immunized mother (MCF lambs;  = 14) or reared with colostrum of ewes that were not immunized against Sheep pox, as the control (C lambs;  = 7), using virus neutralization index.

Molecular characterization of lumpy skin disease virus in Iran (2014-2018).

Lumpy skin disease was first reported in the western provinces of Iran in 2014, and this was followed by several outbreaks throughout the country. In this study, 10 Iranian lumpy skin disease virus (LSDV) samples collected during the period of 2014-2018 were characterized by sequence analysis of the GPCR, LSDV142, and IL10LP genes. Sequence comparison of the respective genes revealed a close relationship between Iranian LSDV isolates and viruses from Asia and Europe.
