Identification and preclinical evaluation of MMV676558 as a promising therapeutic candidate against Clostridioides difficile.

Clostridioides difficile, a gram-positive, toxin-producing, spore-forming anaerobe, is a major cause of antibiotic-associated diarrhoea. The bacterium's intrinsic drug resistance limits current treatment options to fidaxomicin and vancomycin for initial episodes, with anti-toxin B monoclonal antibody or faecal microbiota transplantation recommended for complicated or recurrent cases. This underscores the urgent need for novel therapeutics.

Teicoplanin Suppresses Vegetative and Spore Outgrowth.

In recent decades, the incidence of infection (CDI) has remained high in both community and health-care settings. With the increasing rate of treatment failures and its ability to form spores, an alternative treatment for CDI has become a global priority. We used the microdilution assay to determine minimal inhibitory concentrations (MICs) of vancomycin and teicoplanin against 30 distinct strains isolated from various host origins.

A new species of Chlamydia isolated from Siamese crocodiles (Crocodylus siamensis).

Chlamydia is a known pathogen in both saltwater and freshwater crocodiles. However, the exact species/strain has not been clearly identified. In this study, we successfully cultivated Siamese crocodile Chlamydia in McCoy cells at a temperature of 30°C.

Antimicrobial Effect of Asiatic Acid Against Is Associated With Disruption of Membrane Permeability.

Antibiotic resistance is a major concern in , the causative agent of antibiotic-associated diarrhea. Reduced susceptibility to first- and second-line agents is widespread, therefore various attempts have been made to seek alternative preventive and therapeutic strategies against this pathogen. In this work, the antimicrobial properties of asiatic acid were evaluated against .
