Differential Susceptibility of Bacteria to Mouse Paneth Cell a-Defensins under Anaerobic Conditions

Antibiotics, 2014
Small intestinal Paneth cells secrete a-defensin peptides, termed cryptdins (Crps) in mice, into the intestinal lumen, where they confer immunity to oral infections and define the composition of the ileal microbiota.

Isolation of Obligate and Facultative Anaerobic Bacteria from Feline Subcutaneous Abscesses.

Journal of Veterinary Medical Science, 1996
A total of 113 specimens collected from purulent skin lesions of household cats was examined bacteriologically. Ninety seven isolates obtained from 74 specimens (65.5%). Of these, 11 specimens (9.7%) contained obligate anaerobes only, 18 specimens (15.9%) yielded both obligate and facultative anaerobes.

Cryo‐EM structure of GH43 β‐Xylosidase from Enterobacter cloacae provides insights into substrate specificity and the role of an auxiliary domain in enzymatic activity

The FEBS Journal, EarlyView.
Xylan, the second most abundant plant cell wall polysaccharide, is degraded by β‐xylanases and β‐xylosidases. Here, we present the 2.65 Å cryo‐EM structure of Enterobacter cloacae β‐xylosidase (EcXyl43, GH43) and the 2.4 Å X‐ray structure of its inactive F507A mutant.

Major gut microbiota perturbations in firstborn infants compared to those with older siblings soon after delivery

BMC Pediatrics
Background The gut microbiota may influence immune maturation during infancy. While cesarean delivery is known to delay acquisition of a mature anaerobic microbiota, the influence of being firstborn on early gut colonization is less well studied. Methods

Utility of anaerobic bottles for the diagnosis of bloodstream infections

BMC Infectious Diseases, 2020
Background Obligate anaerobes usually account for less than 10% of bacteria recovered from blood cultures (BC). The relevance of routine use of the anaerobic bottle is under debate.

Isolation and Identification of Erysipelothrix sp. in Hybrid Grouper (Epinephelus fuscoguttatus × E. lanceolatus) in Taiwan

Journal of Fish Diseases, EarlyView.
ABSTRACT In February 2025, a mortality event of unknown aetiology occurred at a hybrid grouper (Epinephelus fuscoguttatus × Epinephelus lanceolatus) aquaculture farm in southern Taiwan, with sporadic daily deaths persisting for a month. Four moribund groupers were collected over three sampling intervals for diagnostic investigation.

Characterization of a heme-degrading enzyme that mediates fitness and pathogenicity in Enterococcus faecalis

mBio
Enterococcus faecalis, a gut commensal, is a leading cause of opportunistic infections. Its virulence is linked to its ability to thrive in hostile environments, which includes host-imposed metal starvation. We recently showed that E.

Oral and Pancreatobiliary Microbiota in Cancer: A Systematic Review of Compositional Alterations and Their Clinical Implications

Journal of Oral Pathology &Medicine, EarlyView.
ABSTRACT Background Associations between microbial dysbiosis and malignancies of the pancreatobiliary system have been described in recent studies. As a result of the limited number of studies that have been done specifically on the malignancies of the biliary tract, information regarding oral, biliary and tumour‐related microbial alterations was ...
