Effect of treatment with Lactococcus lactis NZ9000 on intestinal microbiota and mucosal immune responses against Clostridium perfringens in broiler chickens
Alterations in intestinal microbiota can modulate the developing avian intestinal immune system and, subsequently, may impact on resistance to enteric pathogens. The aim was to demonstrate that early life exposure to Lactococcus lactis, could affect either susceptibility or resistance of broilers to necrotic enteritis (NE). L. lactis NZ9000 (rL. lactis) pre-treatment at 1, 7, 14 and 21 days of age (DOA) led to a significant decrease in NE lesion scores in Clostridium perfringens infected chickens. C. perfringens Infection was associated with spatial and temporal decreases in mononuclear phagocytes and CD4+ αβ T cells. ...

A rare case of mycotic aortic aneurysm with Clostridium perfringens culture
In this study, we presented a clinical report detailing the diagnosis of a mycotic aneurysm caused byC. perfringens in the thoracic aorta in a 66-year-old male patient with a history of diabetes mellitus and a recent prostate biopsy. Furthermore, we discussed the surgical approach and overall management strategy to address this case. (Source: Clinical Case Reports)

Types A and F < em > Clostridium perfringens < /em > in healthcare wastewater from Ghana
Appl Environ Microbiol. 2023 Dec 5:e0161923. doi: 10.1128/aem.01619-23. Online ahead of print.ABSTRACTClostridium perfringens causes gas gangrene and food poisoning in humans, and monitoring this bacterium is important for public health. Although whole-genome sequencing is useful to comprehensively understand the virulence, resistome, and global genetic relatedness of bacteria, limited genomic data from environmental sources and developing countries hamper our understanding of the richness of the intrinsic genomic diversity of this pathogen. Here, we successfully accumulated the genetic data on C. perfringens strains isola...

Evaluation of the additive effects of volatile fatty acids and moderate heat treatment for enhancing the inactivation of vegetative cells and spores of Clostridium perfringens by flow cytometry
CONCLUSIONS: The use of flow cytometry as an original method for evaluating the treatment of Clostridium perfringens is of interest because of its simplicity, short time to obtain results, and the level of information provided on the microbial population (impact on metabolism). A combination of mild treatments (moderate heat treatment + volatile fatty acids) to decrease the Clostridium perfringens concentration when these bacteria sporulate is a very promising finding for inhibiting Clostridium perfringens propagation.PMID:38007214 | DOI:10.1016/j.anaerobe.2023.102802 (Source: Anaerobe)

Comparison of mCP and TSC Media to Enumerate < em > Clostridium perfringens < /em > in Surface Water Samples
Pol J Microbiol. 2023 Nov 24. doi: 10.33073/pjm-2023-039. Online ahead of print.ABSTRACTThe Clostridium perfringens bacteria are used to assess water quality as an indicator parameter. If detected, it can confirm the occurrence of past fecal contamination. Tests determining C. perfringens in water samples are usually performed by membrane filtration where filters are incubated on selective media under anaerobic conditions. Available media include mCP and TSC. The aim of this study was to compare the relative recovery of C. perfringens (including spores) from surface water samples and to determine the performance characteri...
