ORIGINAL_ARTICLE The aim of the performed field and laboratory investigations was to determine the commonest enteropathogens in neonatal and juvenile lambs and goat kids, as well as induced macro- and microscopic alterations in the different digestive system compartments. The study comprised a total of 850 newborn and juvenile lambs (600) and goat kids (250) from 9 private dairy farms (3 goat farms, 6 sheep farms). The age of animals was from 24 hours to 20 days. The following rapid antigen detection tests were used: (Rainbow calf scour 5 BIO K 306, Monoclonal Antibody anti-Coronavirus аnd Rotavirus FITC conjugated, BIOX Diagnostics, Belgium). Gross anatomy and histopathological examination of tissue samples was performed on 21 carcasses (9 goat kids and 12 lambs) from animals that died with signs of gastroenteritis. The main detected agents of intestinal infections were Cryptosporidium parvum, rotaviruses, coronaviruses and Escherichia coli. https://macvetrev.mk/Files/Article/2021/10.2478/macvetrev-2021-0015/macvetrev-2021-0015.pdf 2021-10-15T09:00:00 111 117 10.2478/macvetrev-2021-0015 pathology goat kids lambs gastroenteritis coronavirus rotavirus Ismet Kalkanov ismet_88@abv.bg false 1 Department of General and Clinical Pathology, Faculty of Veterinary Medicine, Trakia University, Student Campus, 6000 Stara Zagora, Bulgaria LEAD_AUTHOR Ivan Dinev false 2 Department of General and Clinical Pathology, Faculty of Veterinary Medicine, Trakia University, Student Campus, 6000 Stara Zagora, Bulgaria AUTHOR Ivan Zarkov false 3 Department of Veterinary Microbiology, Infectious and Parasitic Diseases, Faculty of Veterinary Medicine, Trakia University, Student Campus, 6000 Stara Zagora, Bulgaria AUTHOR Tzipori, S., Sherwood, D., Angus, K.W., Campebell, I., Gordon, M.
