A rod-shaped, facultative anaerobic, Gram-stain-positive bacteria, isolated from the cecum of a mini-pig, was designated as strain YH-lac23. Analysis of 16S rRNA gene sequences revealed that the strain was closely related to JCM 33273 (97.9 %), KCTC 21027 (96.2 %) and KCTC 21010 (95.7 %). Analysis of housekeeping gene sequences ( and ) revealed that the strain formed a sub-cluster with . The average nucleotide identity value for YH-lac23 and its most closely related strain () is 80.7 %. The main fatty acids are Cω9 and C. The cell wall contains the peptidoglycan of -diaminopimelic acid. The G+C content of the genomic DNA is 59.8 mol%. In view of the chemotaxonomic, phenotypic and phylogenetic properties, YH-lac23 (=KCTC 25006=JCM 33998) represents a novel taxon. The name sp. nov. is proposed.

Mitrofanoff complications: time-to-event analysis of split versus intact appendix and meta-analysis.
World J Urol

Division of Urology, Department of Surgery, The Hospital for Sick Children, Toronto, ON, Canada.
Objectives: To assess the complication rates associated with split versus intact appendix Mitrofanoff procedures using a single-center retrospective analysis and a systematic review with meta-analysis.
Subjects And Methods: The study comprised a retrospective cohort analysis at a single institution, analyzing patients who underwent a laparoscopic-assisted Mitrofanoff with or without splitting the appendix from 2005 to 2016. The focus was on complications related to both Mitrofanoff and ACE channels.

Parasites impact wildlife populations and ecosystem health, thereby demanding regular monitoring. As part of the national conservation effort to preserve the free-ranging sirenians in Colombia, a parasitological survey was conducted between 2011 and 2023 on naturally deceased Antillean manatees (Trichechus manatus manatus). A total of 17 stranded carcasses were analysed for the occurrence of parasites.

Metataxonomic studies have underpinned a vast understanding of microbial communities residing within livestock gastrointestinal tracts, albeit studies have often not been combined to provide a global census. Consequently, in this study we characterised the overall and common 'core' chicken microbiota associated with the gastrointestinal tract (GIT), whilst assessing the effects of GIT site, bird breed, age and geographical location on the GIT resident microbes using metataxonomic data compiled from studies completed across the world. Specifically, bacterial 16S ribosomal DNA sequences from GIT samples associated with various breeds, differing in age, GIT sites (caecum, faeces, ileum and jejunum) and geographical location were obtained from the Sequence Read Archive and analysed using the MGnify pipeline.

Background: Neutropenic enterocolitis is a serious gastrointestinal complication that can develop in patients undergoing chemotherapy or other immunosuppressive treatments. It is characterized by inflammation and necrosis of the bowel, and most commonly affects the cecum and ascending colon. Although individual case reports have described the features of NE, a comprehensive synthesis of all the published cases is required.

Intestinal perforations lead to a high risk of sepsis-associated morbidity and multi-organ dysfunctions. A perforation allows intestinal contents (IC) to enter the peritoneal cavity, causing abdominal infections. Right- and left-sided perforations have different prognoses in humans, but the mechanisms associated with different cecum and colon perforations remain unclear.
