“…Our result of ICA was lower than those of other studies [2,14,15] in which rate of Rotavirus infection in serologically positive enteric calves by ICA was 15.63%, 12.50% and 10%, respectively. Such variations in rate of Rotavirus infection in examined calves may be due to geographical variation, hygienic measures, environmental conditions, difference in timing of samples collection, clinical phase of the disease is a suitable time for sampling to obtain the optimum result from a test [11].…”

Neonatal diarrhea is the main cause of morbidity and mortality in calves, and Rotavirus is the main viral etiology. The objective of the current study was to study the epidemiological role of Rotavirus infection in diarrheic neonatal cattle and buffaloes 'calves in Assiut Governorate, Egypt. From December 2015 to November 2019, a total number of 315 neonatal calves belonged to different localities of Assiut Governorate, Upper Egypt, were clinically examined. Fecal samples of investigated calves were subsequently collected and serologically tested to reveal-up Rotavirus infection by using latex agglutination test (LAT) and immunochrmatographic assay (ICA). The seropositive samples by LAT and ICA were 16.74% and 8.54%, respectively. The clinical findings of Rotavirus infection in enteric calves were pointed. The percentage of Rotavirus infection was 14.92% (44/295) of clinically diarrheic calves. However, 10% (2/20) of apparently healthy calves (n = 20) harbor Rotavirus in their feces suggesting carrier status. The high percentage of Rotavirus infection (20.13%) was obviously observed in 3 days-4 weeks old calves. There were no significance differences (P < 0.05) between the percentages of Rotavirus infection and sex, species (cattle and buffaloes) and breed (Native and Cross breed) of serologically tested calves. Moreover, there is no significant variations (p < 0.05) between calves under farmer's hand and calves bred in farm in susceptibility to Rotavirus infection. Based on climatologic conditions of Assiut, seropositive cases were more prevalent (P < 0.001) in cold months (22.67%) than the warm and hot months (7.27%) in Assiut.

Acute gastroenteritis (AGE) induced by rotavirus has been a major disease burden in Egypt since 1981 when rotavirus was first reported in humans and calves. Genome segmentation facilitates the emergence of new virus serotypes, which allows reassortment during mixed infections, and is a characteristic feature of the family Reoviridae to which rotavirus belongs. The rotavirus genome involves 11 double-stranded RNA gene segments encoding 6 non-structural (NSP1–6) and 6 structural (VP1–4, VP6, VP7) proteins. Rotavirus A has a zoonotic potential associated with diarrhea. The primary strategy for prevention and control of bovine and human rotavirus infections is vaccination; however, routine rotavirus vaccination has not been implemented in the National Immunization Program. We evaluated studies published over the last 30 years that pertained to the epidemiology of circulating rotavirus genotypes among children, calves, and environmental samples in Egypt. The analysis revealed a rotavirus prevalence of 15%–100%, with diarrhea occurring throughout the year, but generally peaking during the cold months. G1 was the predominant genotype in children, followed by G2, G3, G4, G8, G9, and G12 throughout the study duration. Mixed infections were also detected. G6 was the predominant genotype in calves, followed by G10. There are still gaps in knowledge regarding molecular data of rotavirus infections in humans, animals, and environmental samples in Egypt, as well as the zoonotic potential of rotavirus disease. Therefore, it is critical to continue rotavirus surveillance in Egypt to further understand the epidemiology of rotavirus infections and the emerging new genotypes.
