A total of 1,991 group B streptococcus (GBS) isolates, collected in 2008 and 2009, were tested for non-penicillin susceptibility by broth microdilution, disk testing, and oxacillin screening agar. No GBS isolates were non-penicillin susceptible. Oxacillin and ceftizoxime disk testing results showed that proposed screening criteria are nonspecific. The oxacillin screening agar was specific but of unknown sensitivity.

Although the clustered regularly interspaced short palindromic repeat (CRISPR)-Cas system has been extensively developed since its discovery for eukaryotic and prokaryotic genome editing and other genetic manipulations, there are still areas warranting improvement, especially regarding bacteria. In this study, BRD0539, a small-molecule inhibitor of Cas9 (SpCas9), was used to suppress the activity of the nuclease during genetic modification of , as well as to regulate CRISPR interference (CRISPRi). First, we developed and validated a CRISPR-SpCas9 system targeting the gene of .

Background: Sow longevity and reproductivity are essential in the modern swine industry. Although many studies have focused on the genetic and genomic factors for selection, little is known about the associations between the microbiome and sows with longevity in reproduction.
Results: In this study, we collected and sequenced rectal and vaginal swabs from 48 sows, nine of which completed up to four parities (U4P group), exhibiting reproductive longevity.

We conducted a comparative study of the mammary gland microbiota in female Wistar rats and the microbiota associated with breast cancer (BC) induced by the administration of N-methyl-N-nitrosourea, after surgical treatment, photodynamic therapy (PDT), and chemotherapy (CT). Selective nutrient media and a smear-fingerprint technique were used to study the microbiota. Staphylococcus, Streptococcus, and Lactobacillus were found in the mammary glands of intact rats.

We report the case of a 53-year-old male, hypertensive, who developed compartment syndrome and myositis in the right lower limb. The patient underwent emergency fasciotomies of the anterior, lateral, superficial posterior and deep posterior compartments of the leg and two subsequent surgical debridements, in addition to receiving antibiotic treatment and delayed closure of the fasciotomies with grafts.

(Group A Streptococcus, GAS) is a human pathogen that causes local and systemic infections of the skin and mucous membranes. However, GAS is also found asymptomatically in the nasopharynx of infants. GAS infections, including pharyngitis and invasive pneumosepsis, pose significant public health concerns.
