  • Molecular basis for Clostridium perfringens spore resistance to heat and other environmental stress factors

    Creator:
    Raju, Deepa
    Abstract:
    Clostridium perfringens type A isolates producing enterotoxin (CPE) are an important cause of both food poisoning (FP) and non food borne gastrointestinal diseases (NFBGID) in both humans and animals. C. perfringens type A food poisoning is caused by isolates carrying the CPE encoding gene (cpe) on the chromosome while the...

    Creator:
    Talukdar, Prabhat Kumar
    Abstract:
    Clostridium perfringens is a Gram-positive, anaerobic, spore-forming bacterium that can produce as many as 17 different toxins and are responsible to cause a wide array of gastrointestinal (GI) and histotoxic diseases in humans and animals. As individual strains produce a subset of these toxins, C. perfringens strains can be classified...

  • Inactivation of Clostridium perfringens in Meat Products

    Creator:
    Alnoman, Maryam M.
    Abstract:
    Clostridium perfringens type A strains are one of the main causative agents of gastrointestinal (GI) diseases in human and can cause both food poisoning (FP) and non-food-borne (NFB) diseases. Several factors contribute to the pathogenesis of C. perfringens type A strains including the wide presence of C. perfringens spores with...

    Creator:
    Udompijitkul, Pathima
    Abstract:
    The enterotoxin-producing Clostridium perfringens type A isolates are responsible for the third most common foodborne illness in the United States and can also cause non-foodborne human gastrointestinal (GI) diseases such as antibiotic- associated and sporadic diarrheas. Three important factors contribute to the ability of C. perfringens to cause GI diseases,...

  • Inhibition of Clostridium perfringens spore growth by synergistic effects of different antimicrobials

    Creator:
    Alhabeeb, Rabiaa
    Abstract:
    Clostridium perfringens is a spore-forming anaerobic organism that is commonly present in fresh meat and poultry. The organism's spores can survive a range of food processing methods. C. perfringens type F isolates are the causative agents of C. perfringens type F food poisoning (FP) and non-food borne (NFB) human gastrointestinal...

  • The Inhibitory Activity of Essential Oil Constituents Against Clostridium perfringens Type A Isolates

    Creator:
    Alanazi, Saud
    Abstract:
    C. perfringens type A isolates are the causative agents of C. perfringens type A food poisoning (FP) and non-food-borne (NFB) human gastrointestinal diseases. In this study, we evaluated the antimicrobial effect of essential oil constituents (cinnamaldehyde, eugenol, allyl isothiocyanate (AITC), and carvacrol) against C. perfringens FP and NFB isolates grown...

    Abstract:
    C. perfringens is a spore-forming, gram-positive, anaerobic pathogenic bacterium capable of causing a wide variety of diseases in both humans and animals. However, the two most common illnesses in humans are C. perfringens type A food poisoning (FP) and non-food-borne (NFB) gastrointestinal (GI) illnesses. Interestingly, these two major diseases are...
