History repeats itself: horse originated hyperimmune sera production against SARS CoV-2.

Background/aim/aim: SARS-CoV-2 disease was announced as a pandemic by The World Health Organization in early 2020. It is still threatening the world population. Here, we aimed to produce hyperimmune sera that contain immunoglobulin G and F(ab')2 fragments sourced from horse antibodies as an urgent response to the pandemic.

Distribution of G (VP7) and P (VP4) genotypes of group A bovine rotaviruses from Turkish calves with diarrhea, 1997-2008.

Group A rotaviruses are major enteric pathogens of calves. In order to investigate the genetic diversity of bovine rotaviruses (BRVs), a collection of 53 BRVs, detected from diarrheic calves from several Turkish geographical areas, between 1997 and 2008 was analyzed by RT-PCR for specificities of the outer capsid proteins VP7 (G type) and VP4 (P type), for the first time. Overall, G6 was the predominant G type, detected in 40/53 samples (75.

Segment 10 based molecular epidemiology of bluetongue virus (BTV) isolates from Turkey: 1999-2001.

Bluetongue is a significant arbovirus infection that has a negative impact on ruminant productivity in Turkey. Twenty-one Turkish BTV isolates were analyzed phylogenetically, based on genome segment 10 (Seg-10) nucleotide sequences. These analyses were used to explore the epidemiological background of individual isolates from both a regional and global perspective.
