Effect of a small, acid-soluble spore protein from Clostridium perfringens on the resistance properties of Bacillus subtilis spores.
نویسندگان
چکیده
Alpha/beta-type small, acid-soluble spore proteins (SASP) are essential for the resistance of DNA in spores of Bacillus species to damage. An alpha/beta-type SASP, Ssp2, from Clostridium perfringens was expressed at significant levels in B. subtilis spores lacking one or both major alpha/beta-type SASP (alpha- and alpha- beta- strains, respectively). Ssp2 restored some of the resistance of alpha- beta- spores to UV and nitrous acid and of alpha- spores to dry heat. Ssp2 also restored much of the resistance of alpha- spores to nitrous acid and restored full resistance of alpha- spores to UV and moist heat. These results further indicate the interchangeability of alpha/beta-type SASP in DNA protection in spores.

Characterization of Clostridium perfringens spores that lack SpoVA proteins and dipicolinic acid.
Spores of Clostridium perfringens possess high heat resistance, and when these spores germinate and return to active growth, they can cause gastrointestinal disease. Work with Bacillus subtilis has shown that the spore's dipicolinic acid (DPA) level can markedly influence both spore germination and resistance and that the proteins encoded by the spoVA operon are essential for DPA uptake by the ...
متن کاملDecreased UV light resistance of spores of Bacillus subtilis strains deficient in pyrimidine dimer repair and small, acid-soluble spore proteins.
Loss of small, acid-soluble spore protein alpha reduced spore UV resistance 30- to 50-fold in Bacillus subtilis strains deficient in pyrimidine dimer repair, but gave only a 5- to 8-fold reduction in UV resistance in repair-proficient strains. However, both repair-proficient and -deficient spores lacking this protein had identical heat and gamma-radiation resistance.
متن کاملAntisense-RNA-mediated decreased synthesis of small, acid-soluble spore proteins leads to decreased resistance of clostridium perfringens spores to moist heat and UV radiation.
Previous work has suggested that a group of alpha/beta-type small, acid-soluble spore proteins (SASP) is involved in the resistance of Clostridium perfringens spores to moist heat. However, this suggestion is based on the analysis of C. perfringens spores lacking only one of the three genes encoding alpha/beta-type SASP in this organism. We have now used antisense RNA to decrease levels of alph...

BACKGROUND Clostridium perfringens type A food poisoning (FP) is usually caused by C. perfringens type A strains that carry a chromosomal enterotoxin gene (cpe) and produce spores with exceptional resistance against heat and nitrites. Previous studies showed that the extreme resistance of spores made by most FP strains is mediated, in large part, by a variant of small acid soluble protein 4 (Ss...

Clostridium perfringens is a major cause of food poisoning (FP) in developed countries. C. perfringens isolates usually induce the gastrointestinal symptoms of this FP by producing an enterotoxin that is encoded by a chromosomal (cpe) gene. Those typical FP strains also produce spores that are extremely resistant to food preservation approaches such as heating and chemical preservatives. This r...
