Objective: To study the pathogen and characteristics of viral diarrhea in children in Changchun area.
Methods: 460 stools specimens were collected from children with acute diarrhea cured in the childrens, hospital of Changchun in 2010. Rotavirus were detected by ELISA, caliceverus and astrovirus were detected by reverse transcription-polymerase chain reactions (RT-PCR), adenovirus were detected by polymerase chain reactions (PCR).
Results: A total of 460 specimens were detected. The detection rate of rotavirus, caliceverus, astrovious, adenovious respectively is 35.22%, 20.43%, 9.78%, 3.70%, the detectablerate of mixed infection is 7.61%, children under 2 years old were the major patient. The main genotypes of the virus: rotavirus (G3P[8]), caliceverus (GII-4), astrovious (type I), adenovious (Ad41).
Conclusion: Rotavirus is the main pathogen in Changchun. Followed by caliceverus, astrovious, adenovious.

Background: Bovine viral diarrhoea virus genotype 1 (BVDV-1) and bluetongue virus (BTV) are potent viral pathogens that may be transmitted through semen, resulting in the spread of diseases via artificial insemination. Thus, establishing an early detection method for BVDV-1 and BTV infection is important for the trading of semen. In this study, we developed two RT‒ddPCR methods to detect BVDV-1 and BTV, and each method was evaluated for repeatability, limit of detection and specificity.

Unlabelled: Mutations affecting flagellin (FliC) have been shown to be hypervirulent in animal models and display increased toxin production and alterations in central metabolism. The regulation of flagellin levels in bacteria is governed by a tripartite regulatory network involving , , and , which creates a feedback system to regulate flagella production. Through genomic analysis of clade 5 strains (non-motile), we identified they have jettisoned many of the genes required for flagellum biosynthesis yet retain the major flagellin gene and regulatory gene .

Background: Myanmar is one of the countries in Southeast Asia where serious dengue outbreaks occur and Yangon is among the regions with the highest number of cases in the country. Many infections including dengue are common in Yangon during the rainy season, and co-infections may also occur. Adults are more likely than children to experience co-infections of dengue and other diseases.

In November 2020, a volunteer group reported an outbreak of an infectious disease with a high fatality rate and flu-like symptoms among stray cats in Aoshima, a remote island in Ehime, Japan. Nine adult cats with severe symptoms were hospitalized. Feline calicivirus (FCV) was isolated from pharyngeal swabs of six hospitalized cats.

Bovine viral diarrhea virus (BVDV) is the causative agent of bovine viral diarrhea, which causes significant economic loss to the global livestock industry. Despite the widespread use of inactivated BVDV vaccines, highly pathogenic strains continue to emerge. In China, regional variations in BVDV subtypes, morbidities, and symptoms, however, only the BVDV 1a subtype vaccine is currently approved.
