Comparison of Preston agar and a blood-free selective medium for detection of Campylobacter jejuni in food. 1991

The present collaborative study compares recovery of Campylobacter jejuni from food in 2 agar media. Six laboratories analyzed 8 samples each of chicken liver inoculated with Campylobacter jejuni. Samples were enriched in Preston broth and isolation was carried out on Preston agar (PA) and campylobacter blood-free selective medium (CBFS), a charcoal-based medium with cefoperazone and amphoteracin as antibiotic supplements. There was no difference in the recovery rate between the 2 agar media; however, the specificity of CBFS was better than that of PA. There was a slightly better growth of campylobacters, and competing organisms were more inhibited on CBFS than on PA.

UI	MeSH Term	Description	Entries
D008099	Liver	A large lobed glandular organ in the abdomen of vertebrates that is responsible for detoxification, metabolism, synthesis and storage of various substances.	Livers
D011200	Poultry	Domesticated birds raised for food. It typically includes CHICKENS; TURKEYS, DUCKS; GEESE; and others.	Fowls, Domestic,Domestic Fowl,Domestic Fowls,Fowl, Domestic,Poultries
D005516	Food Microbiology	The presence of bacteria, viruses, and fungi in food and food products. This term is not restricted to pathogenic organisms: the presence of various non-pathogenic bacteria and fungi in cheeses and wines, for example, is included in this concept.	Microbiology, Food
D000362	Agar	A complex sulfated polymer of galactose units, extracted from Gelidium cartilagineum, Gracilaria confervoides, and related red algae. It is used as a gel in the preparation of solid culture media for microorganisms, as a bulk laxative, in making emulsions, and as a supporting medium for immunodiffusion and immunoelectrophoresis.
D000818	Animals	Unicellular or multicellular, heterotrophic organisms, that have sensation and the power of voluntary movement. Under the older five kingdom paradigm, Animalia was one of the kingdoms. Under the modern three domain model, Animalia represents one of the many groups in the domain EUKARYOTA.

D016123	Campylobacter jejuni	A species of bacteria that resemble small tightly coiled spirals. Its organisms are known to cause abortion in sheep and fever and enteritis in man and may be associated with enteric diseases of calves, lambs, and other animals.	Campylobacter fetus subsp. jejuni,Vibrio hepaticus,Vibrio jejuni
D016895	Culture Media, Serum-Free	CULTURE MEDIA free of serum proteins but including the minimal essential substances required for cell growth. This type of medium avoids the presence of extraneous substances that may affect cell proliferation or unwanted activation of cells.
