Novel and rare β-lactamase genes of Bacteroides fragilis group species: Detection of the genes and characterization of their genetic backgrounds
CONCLUSIONS: Based on these observations, β-lactamases produced by rare β-lactamase genes in B. fragilis group strains should not be overlooked because they could encode important resistance phenotypes.PMID:38360202 | DOI:10.1016/j.anaerobe.2024.102832 (Source: Anaerobe)

Microscopy methods for Clostridioides difficile
Anaerobe. 2024 Feb 8:102822. doi: 10.1016/j.anaerobe.2024.102822. Online ahead of print.ABSTRACTMicroscopic technologies including light and fluorescent, transmission electron microscopy (TEM), scanning electron microscopy (SEM), and cryo-electron microscopy have been widely utilized to visualize Clostridioides difficile at the molecular, cellular, community, and structural biology level. This comprehensive review summarizes the microscopy tools (fluorescent and reporter system) in their use to study different aspects of C. difficile life cycle and virulence (sporulation, germination) or applications (detection of C. diffi...

The burden of Clostridioides difficile infections in South-East Asia and the Western Pacific: A narrative review
CONCLUSION: The regional CDI burden in Asia is still incompletely documented, seemingly due to low awareness and limited laboratory testing. Despite this apparent under recognition, the current CDI burden highlights the need for broader surveillance and for application of preventative measures against CDI in Asia.PMID:38336258 | DOI:10.1016/j.anaerobe.2024.102821 (Source: Anaerobe)

Polyphasic molecular approach to the characterization of methanogens in the saliva of Tunisian adults
CONCLUSION: Our study showed the presence of methanogens in the oral microbiota of Tunisian adults with an unprecedented relatively high prevalence. Choice of methodology is also central to picturing the real prevalence and diversity of such minor taxa in the oral microbiota.PMID:38309618 | DOI:10.1016/j.anaerobe.2024.102820 (Source: Anaerobe)

Bacteroides and related species: The keystone taxa of the human gut microbiota
Anaerobe. 2024 Jan 10;85:102819. doi: 10.1016/j.anaerobe.2024.102819. Online ahead of print.ABSTRACTMicrobial communities play a significant role in maintaining ecosystems in a healthy homeostasis. Presently, in the human gastrointestinal tract, there are certain taxonomic groups of importance, though there is no single species that plays a keystone role. Bacteroides spp. are known to be major players in the maintenance of eubiosis in the human gastrointestinal tract. Here we review the critical role that Bacteroides play in the human gut, their potential pathogenic role outside of the gut, and their various methods of ada...

Production and purification of Clostridium perfringens type C beta-toxin and IgG and IgY antitoxins
CONCLUSIONS: C. perfringens type C beta-toxin and sheep or chicken anti-beta toxin IgG and IgY antibodies were successfully produced and purified using a simple protocol. This protocol can be used for the production of components used in the diagnosis and research of necrotic enteritis caused by C. perfringens type C, as well as for the evaluation of existing vaccines and the development of new preventive methods against this disease.PMID:38163631 | DOI:10.1016/j.anaerobe.2023.102817 (Source: Anaerobe)

Enhancing biogas generation from lignocellulosic biomass through biological pretreatment: Exploring the role of ruminant microbes and anaerobic fungi
CONCLUSIONS: Optimizing fungal colonization and ligninolytic enzyme production, such as manganese peroxidase and laccase, significantly enhances the efficiency of fungal pretreatment. Integrating anaerobic fungi through bioaugmentation during mainstream processing demonstrably increases methane production. This study opens promising avenues for further research and development of these microorganisms for bioenergy production.PMID:38145708 | DOI:10.1016/j.anaerobe.2023.102815 (Source: Anaerobe)
