Epidemiology
In a study of 25 diarrheic calves from Egyptian farms, 76% tested positive for one or more enteric viruses, with rotavirus detected in 48%, norovirus in 24%, and astrovirus in 32% of the samples [PMID:27686074].
Clinical Presentation
The study identified that one-month-old calves were the most susceptible group to viral infections leading to neonatal diarrhea [PMID:27686074].
Diagnosis
Reverse transcription polymerase chain reaction (RT-PCR) was utilized to detect rotavirus, norovirus, astrovirus, torovirus, coronavirus, and bovine viral diarrhea virus, identifying co-infections in 37% of positive samples [PMID:27686074].
