is an important bioresource to produce various antibacterial natural products, however, the time-consuming and labor-intensive genome editing toolkits hindered the construction and application of engineered strains, and this study aimed to establish an efficient CRISPR/Cas9n genome editing system in . Initially, the CRISPR/Cas9-mediated editing tool was employed to replace those awkward genome editing tools that relied on homologous recombination, while the off-target Cas9 exhibited high toxicity to Sf01. Therefore, the nickase mutation D10A, high-fidelity mutations including N497A, R661A, Q695A, and Q926A, and thiostrepton-induced promotor P were incorporated into the Cas9 expression cassette, which reduced its toxicity.

Antibiotics are commonly used in pig farming to control infections caused by diarrhea-causing Escherichia coli (E. coli). However, improper or excessive use of antibiotics in pigs can enhance antibiotic resistance (ABR).

are opportunistic pathogens which can cause mastitis in dairy cattle. mastitis often has a poor cure rate and can lead to the development of chronic infection, which has an impact on both health and production. However, there are few studies which aim to fully characterize by whole-genome sequencing from bovine mastitis cases.

This cross-sectional study assessed the prevalence, bacterial distribution, antimicrobial susceptibility, and potential risk factors associated with subclinical mastitis (SCM) in small-holder dairy herds in Gansu Province, Northwest China. Forty small-holder cow farms were randomly selected from eight cities/counties in six districts of Gansu Province, and a total of = 530 lactating cows were included in this study. SCM prevalence was noted at 38.
