Abstract

ABSTRACT

Occurrence of Clostridium perfringens contamination in poultry feed ingredients: Isolation, identification and its antibiotic sensitivity pattern

“…perfringens in 38% of the ingredients used in broiler feed production, with the highest level of contamination in fish meal and meat meal. Schocken-Iturrino et al. (2010) observed 42% of broiler feed samples were contaminated by C .…”

Analysis of the Presence of <i>Clostridium perfringens</i> in Feed and Raw Material Used in Poultry Production

“…In a survey conducted in three different cities of the state of Sao Paulo, Schocken-Iturrino et al [4] observed that, among 90 samples of broiler feed analyzed, 42% were contaminated by C. perfringens, and mean counts were 3.69 × 10 2 CFU/g. The high counts found in this survey were associated in Good Manufacturing Practices failures, mainly the lack of hygiene in the production and little care in the storage of the feeds.…”

“…Microbiological analyses carried out in raw material used in feed production, mainly feather, meat, and organ meal have shown different levels of contamination by C. perfringens, depending on the quality of the raw material and on the hygienic procedures used during processing [2]. These sources, when contaminated, may be vehicles of important pathogens for the flocks [3] [4], leading to decreased feed efficiency and health problems, which end up in the development of diseases and considerable economic losses to this production system.…”

Broiler recycled litter treatments against Clostridium perfringens and enterobacteria in conventional and dark house systems

“…Pink (lactose fermenter) and colorless (lactose nonfermenter) colonies were counted. For C. perfringens quantitative analysis, samples subjected to serial decimal dilutions were plated in duplicate in sulfite polymyxin sulfadiazine selective medium (SPS, Merck Sharp & Dohme, Kenilworth, NJ, USA) and incubated in anaerobic jar at 37°C, for at least 48 hours, according to Schocken-Iturrino et al (2010). Only black colonies (sulfite reducers) were counted.…”
