Mesomycoplasma (Mycoplasma) ovipneumoniae dihydrolipoamide dehydrogenase is an immunogenic plasminogen binding protein and a putative adhesin.

The interaction of Mesomycoplasma (Mycoplasma) ovipneumoniae (M. ovipneumoniae) with host cells is a pivotal step in the infection process, underlining the necessity to develop vaccines and therapeutic approaches targeting the pathogen's key invasion mechanisms. The bacterium's capacity for adherence, invasion, and subsequent evasion of the host immune response underpins its pathogenicity, rendering adherence genes feasible vaccine targets.

The GE296_RS03820 and GE296_RS03830 genes are involved in capsular polysaccharide biosynthesis in Riemerella anatipestifer.

Riemerella anatipestifer is a pathogenic bacterium that causes duck serositis and meningitis, leading to significant harm to the duck industry. To escape from the host immune system, the meningitis-causing bacteria must survive and multiply in the bloodstream, relying on specific virulence factors such as capsules. Therefore, it is essential to study the genes involved in capsule biosynthesis in R.

DDX5 inhibits inflammation by modulating m6A levels of TLR2/4 transcripts during bacterial infection.

DExD/H-box helicases are crucial regulators of RNA metabolism and antiviral innate immune responses; however, their role in bacteria-induced inflammation remains unclear. Here, we report that DDX5 interacts with METTL3 and METTL14 to form an m6A writing complex, which adds N6-methyladenosine to transcripts of toll-like receptor (TLR) 2 and TLR4, promoting their decay via YTHDF2-mediated RNA degradation, resulting in reduced expression of TLR2/4. Upon bacterial infection, DDX5 is recruited to Hrd1 at the endoplasmic reticulum in an MyD88-dependent manner and is degraded by the ubiquitin-proteasome pathway.

Characterization of RaeE-RaeF-RopN, a putative RND efflux pump system in Riemerella anatipestifer.

Resistance-nodulation-division (RND) efflux systems are ubiquitous in Gram-negative bacteria and play a predominant role in antimicrobial resistance and other diverse phenotypes, but the knowledges of RND efflux systems are poorly understood so far in Riemerella anatipestifer. According to the sequence annotation, RIA_1117-RIA_1118-RIA_1119 operon in RA-GD strain encodes a putative tripartite RND efflux system. RIA_1117, RIA_1118 and RIA_1119 genes encode an outer member protein (OMP), an inner membrane pump protein (pump transporter), and a periplasmic membrane fusion protein (MFP), respectively.

C-strain-infected BM-imDCs showed a greatly enhanced degree of maturation, and could effectively promote the expansion and proliferation of allogeneic naive T cells.

Identification and characterization of a novel subgenotype of bovine viral diarrhea virus isolated from dairy cattle in Northwestern China.

Bovine viral diarrhea virus (BVDV) was detected by RT-PCR in 105 out of 391 samples which were collected from five dairy farms in Ningxia, China during 2010-2011. Non-cytopathogenic BVDV was isolated from 13 samples and a 230-bp fragment of the 5'-untranslated region was amplified and sequenced. While the predominant subgenotypes were BVDV-1b and BVDV-1d, a potentially novel subgenotype was identified by phylogenetic analysis, which may have implications for vaccine development.
