Department of Veterinary Medicine, Università Aldo Moro di Bari, 70010 Valenzano, Italy.
Kobuviruses (KoVs) are a group of small, non-enveloped RNA viruses classified in the genus within the family, comprising Aichivirus species A to F. KoVs have been identified in humans and several mammals, including domestic ungulates. This study investigated the presence of KoVs in a collection of bovine stool samples ( = 38) obtained from animals with enteritis or without clinical signs.

Article Synopsis
- Livestock is key for food security and the economy, but viral infections can harm cattle health and pose risks to human and animal health, making virus identification critical for prevention and control.
- The study focused on characterizing viral communities in cattle fecal samples from Ubaté Province, Colombia, using advanced metagenomic sequencing techniques.
- Findings showed a stable viral composition dominated by Picornaviridae family members, with significant discoveries of viruses like Enterovirus E and Bovine Astrovirus, marking the first report of certain veterinary-important viruses in Colombia.

Calf diarrhea results in significant economic loss and is caused by a variety of pathogens, including enteric viruses. Many of these viruses, including bovine norovirus (BNoV), bovine torovirus (BToV), and bovine kobuvirus (BKoV), are recognized as the causative agents of diarrhea; however, they remain understudied as major pathogens. We developed a multiplex reverse-transcription quantitative real-time PCR (RT-qPCR) assay for rapid and simple detection of BNoV, BToV, and BKoV.

Introduction: Calf diarrhea is a complex disease that has long been an unsolved problem in the cattle industry. Ningxia is at the forefront of China in the scale of cattle breeding, and calf diarrhea gravely restricts the development of Ningxia's cattle industry.
Methods: From July 2021 to May 2022, we collected diarrhea stool samples from calves aged 1-103 days from 23 farms in five cities in Ningxia, and performed PCR using specific primers for 15 major reported pathogens of calf diarrhea, including bacteria, viruses, and parasites.

Aichivirus D (AiV-D) is a newly emerging detected in bovine and sheep, and information is limited regarding its biological significance and prevalence. This study aimed to explore both the prevalence and characteristics of AiV-D in yaks. From May to August 2021, 117 fecal samples were collected from yaks with diarrhea in three provinces of China's Qinghai-Tibet Plateau, 15 of which were selected and pooled for metagenomic analysis.
