“…Drzewiecka et al [34, 35], by the use of serological and molecular methods as well as the Dienes test, proved that P. mirabilis strains isolated from feces and urine of patients were in fact the same spreading clone causing autoinfection and nosocomial infection. Wang et al [148] reported the case of food poisoning in a restaurant in Beijing, China, caused by P. mirabilis . The same clone, identified by genotyping and the Dienes method, was detected in the consumed food and in stools of consumers as well as the cook handler and the waiter who, due to the lack of hygiene, most probably had transported the bacteria to the meal.…”

Proteus spp. bacteria were first described in 1885 by Gustav Hauser, who had revealed their feature of intensive swarming growth. Currently, the genus is divided into Proteus mirabilis, Proteus vulgaris, Proteus penneri, Proteus hauseri, and three unnamed genomospecies 4, 5, and 6 and consists of 80 O-antigenic serogroups. The bacteria are known to be human opportunistic pathogens, isolated from urine, wounds, and other clinical sources. It is postulated that intestines are a reservoir of these proteolytic organisms. Many wild and domestic animals may be hosts of Proteus spp. bacteria, which are commonly known to play a role of parasites or commensals. However, interesting examples of their symbiotic relationships with higher organisms have also been described. Proteus spp. bacteria present in soil or water habitats are often regarded as indicators of fecal pollution, posing a threat of poisoning when the contaminated water or seafood is consumed. The health risk may also be connected with drug-resistant strains sourcing from intestines. Positive aspects of the bacteria presence in water and soil are connected with exceptional features displayed by autochthonic Proteus spp. strains detected in these environments. These rods acquire various metabolic abilities allowing their adaptation to different environmental conditions, such as high concentrations of heavy metals or toxic substances, which may be exploited as sources of energy and nutrition by the bacteria. The Proteus spp. abilities to tolerate or utilize polluting compounds as well as promote plant growth provide a possibility of employing these microorganisms in bioremediation and environmental protection.

“…uted in the natural environment and the intestinal tract of humans and animals. P. mirabilis is recognized as an opportunistic pathogen associated with urinary tract infection (1), nosocomial infection (2), and food poisoning (3). Transposons, known as "jumping genes," are specific DNA segments inserting into one or more sites in one or more genomes (4).…”

A novel 65.8-kb multidrug resistance transposon, designated Tn, was characterized in a isolate from chicken in China. Tn contains 18 different antimicrobial resistance genes, including cephalosporinase gene and fluoroquinolone resistance genes and ' It carries a class 1/2 hybrid integron composed of and a 3' conserved segment of the class 1 integron. Tn is derived from Tn via acquisition of new mobile elements and resistance genes.

“…They can be present in undercooked meals since their spores are heat resistant. The bacteria are able to produce more cells under favourable conditions (Wang et al, 2010), therefore, this organism becomes an important concern especially in situations where snails are grilled for the preparation of khebab without adequate cooking to eliminate the spores. The differences in the microbial load of the two species might have resulted from the peculiar habitat of the species.…”

In the Greater Accra Region there is high demand in consumption of molluscs, which indicates the need for studies on the possibility of disease transmission. Snail meat is usually susceptible to microbial contamination. Shelling is difficult with possibilities of cross contamination. Slime on the meat becomes a hurdle during commercial processing. The objective of the study was to establish the differences in the microbial load of African land snails (Achatina achatina and Archachatina marginata) from two sources (market and breeding farm) and to enumerate some consumer concerns about the snail meat. The results found that the total viable count (log 10 CFU/g) ranged from 6.61±1.25 to 8.29±1.02. The total of coliform count (log 10 CFU/g) ranged from 8.50±0.57 to 5.61±1.51. Salmonella count (log 10 CFU/g) ranged from 2.91±3.19 to 7.39±0.45. Staphylococcus, Bacillus and Pseudomonas counts (log 10 CFU/g) ranged from 7.68±1.40 to 2.66±2.99; 4.90±1.07 to 1.53±1.68 and 5.66±0.14 to 3.97±0.74, respectively. Most microorganisms identified were from the Enterobateriaceae family. Shelling, slime removal, contamination, price, packaging were problems associated with snail meat.
