Differential gene expression analysis shows that cephalosporin resistance is intrinsic to Clostridioides difficile strain 630.

Clostridioides difficile infection (CDI) is the most common nosocomial infection in the US. CDI has become a growing concern due to C. difficile's resistance to several antibiotics, including cephalosporins.

Inhibitory effect of indole analogs against Paenibacillus larvae, the causal agent of American foulbrood disease.

Paenibacillus larvae, a Gram-positive bacterium, causes American foulbrood (AFB) in honey bee larvae (Apis mellifera Linnaeus [Hymenoptera: Apidae]). P. larvae spores exit dormancy in the gut of bee larvae, the germinated cells proliferate, and ultimately bacteremia kills the host.

Comparison of in vitro methods for the production of Paenibacillus larvae endospores.

Paenibacillus larvae endospores are the infectious particles of the honey bee brood disease, American Foulbrood. We demonstrate that our previously published protocol (Alvarado et al., 2013) consistently yields higher numbers and purer preparations of P.

How enteric pathogens know they hit the sweet spot.

Requirements for in vitro germination of Paenibacillus larvae spores.

Paenibacillus larvae is the causative agent of American foulbrood (AFB), a disease affecting honey bee larvae. First- and second-instar larvae become infected when they ingest food contaminated with P. larvae spores.
