When tested in chickens, the antibody-guided platform was capable of inducing specific IgG production within one week post-immunization. However, use of this method beyond its initial conception as a vaccine delivery tool has not been fully exploited.

C. perfringens mono-species biofilms were able to protect the bacterial cells from the action of commonly used disinfectants. Sodium hypochlorite solution was shown to be effective on C. perfringens biofilms. Mono-species biofilms were more tolerant to disinfectants than the mixed biofilms. Abstract.

IOWA STATE UNIVERSITY - 2015 - Thèse en ligne : Efficacy of decreased nitrite concentrations on Clostridium perfringens outgrowth during an Appendix B cooling cycle for ready-to-eat meats. Abstract Increased popularity of natural and organic processed meats can be attributed to the growing consumer demand of preservative-free foods.
In order to meet consumer demand, processors have begun using celery juice concentrate in place of sodium nitrite creating no-nitrate-no-nitrite added meat products while maintaining the characteristics unique to conventionally cured processed meats. Natural cures typically have lower ingoing nitrite concentrations which could allow for increased pathogen growth, such as Clostridium perfringens, during cooling as required by USDA, FSIS Appendix B. The objective of this study was to investigate the implications associated with reduced nitrite concentrations and their ability to inhibit C. perfringens outgrowth during a 15 hour cooling cycle.
Nitrite treatments of 0 ppm, 50 ppm, and 100 ppm were tested in a broth system inoculated with a three-strain C. perfringens cocktail and treated with a 15 hour stabilization cycle.

Probabilistic calculations combining thermal equations and microbiological models. Thermal equations parameters assessed by tests carried out in a kitchen. Possibility of using this method to validate cooling operations in catering. Abstract The cook-chill operation, a widely used process within central cooking facilities, implies that cooked dishes have to be quickly cooled down immediately after cooking in order to prevent any food-borne diseases due to Clostridium perfringens. This document presents an experimental method to validate the sanitary efficiency of the cooling process. The tests consisted in monitoring food temperature at the center of the containers from the end of cooking until the beginning of cold room storage.
From the monitored time–temperature profiles, thermal cooling equations were established for modeling. Keywords Copyright © 2013 Elsevier Ltd. MICROBIOLOGY AUSTRALIA - MAI 2013 - Food Safety.

Abstract The contamination of enterotoxigenic Clostridium perfringens spores on food contact surfaces posses a serious concern to food industry due to their high resistance to various preservation methods typically applied to control foodborne pathogens.
In this study, we aimed to develop an strategy to inactivate C. perfringens spores on stainless steel (SS) surfaces by inducing spore germination and killing of germinated spores with commonly used disinfectants. The mixture of l-Asparagine and KCl (AK) induced maximum spore germination for all tested C. perfringens food poisoning (FP) and non-foodborne (NFB) isolates.
Incubation temperature had a major impact on C. perfringens spore germination, with 40 °C induced higher germination than room temperature (RT) (20 ± 2 °C). CDC MMWR 17/08/12 Fatal Foodborne Clostridium perfringens Illness at a State Psychiatric Hospital — Louisiana, 2010. August 17, 2012 / 61(32);605-608 Clostridium perfringens, the third most common cause of foodborne illness in the United States (1), most often causes a self-limited, diarrheal disease lasting 12–24 hours.
Fatalities are very rare, occurring in <0.03% of cases (1). Death usually is caused by dehydration and occurs among the very young, the very old, and persons debilitated by illness (2). On May 7, 2010, 42 residents and 12 staff members at a Louisiana state psychiatric hospital experienced vomiting, abdominal cramps, and diarrhea. Within 24 hours, three patients had died. On May 8, a state psychiatric hospital contacted OPH to report three resident deaths that occurred following an outbreak of gastrointestinal illness in patients and staff members that began late in the evening of May 6.

SCIENTIFIC RESEARCH - JUNE 2013 - Some Characters of Cl. perfringens Isolated from Fresh and Marketed Processed Meat. Some Characters of Cl. perfringens Isolated from Fresh and Marketed Processed Meat This study was carried out a fresh meat immediately after slaughter and a marketed processed cattlemeat (sausage and minced meat).
A total of 530 meat samples were examined for the presence of Cl. perfringens, 423 were from fresh meat obtained immediately after slaughtering (108 cattle meat, 101 sheep meat, 100 camel meat and 114 buffaloe meat) and 107 processed meat (57 from sausage and 50 from minced meat). Cl. perfringens was isolated from 204 (48.2%) of fresh meat samples, 61 (56.5%) from cattle, 53 (52.5%) from sheep meat, 45 (45%) from camel meat and 45 (39.5%) from buffaloe meat. The isolation rate of Cl. perfringens was higher in processed meat, it was isolated from 68 (63.6%) of which 45 (78.9%) from sausage and 23 (46%) in minced meat. Cite this paper K.

Name of the Organism: Clostridium perfringens Clostridium perfringens is an anaerobic, Gram-positive, sporeforming rod (anaerobic means unable to grow in the presence of free oxygen). It is widely distributed in the environment and frequently occurs in the intestines of humans and many domestic and feral animals. 2.
Perfringens food poisoning is the term used to describe the common foodborne illness caused by C. perfringens. 3. The common form of perfringens poisoning is characterized by intense abdominal cramps and diarrhea which begin 8-22 hours after consumption of foods containing large numbers of those C. perfringens bacteria capable of producing the food poisoning toxin. Necrotic enteritis (pig-bel) caused by C. perfringens is often fatal. Infective dose--The symptoms are caused by ingestion of large numbers (greater than 10 to the 8th) vegetative cells.
