The increase in S. Paratyphi infection raises concern over the effectiveness of the typhoid fever vaccines in use and highlights the need for more extensive epidemiological study of the pathogen. Epidemiologic investigations found that 83% reported dog contacts, and, of the 11 patients who recalled types of dog food, 8 reported brands produced by Diamond Pet Foods.

Contaminated water or food is the major transmission route of enteric fever. The food products that are predominantly associated with the outbreaks include animal products such as milk, poultry and eggs, as well as food products such as chocolate and peanut butter (Table 1).

The Salmonella infection cycle starts after the ingestion of microbes. Based on the clinical patterns in human salmonellosis, Salmonella strains can be grouped into typhoid Salmonella and non-typhoid Salmonella (NTS). They pose a great threat to the food industry because they are able to adapt to environmental conditions that differ significantly from those in which they normally grow. Virulence (Vi) antigens, a special subtype of K antigen, are found only in three pathogenic serotypes: Paratyphi C, Dublin and Typhi. 3099067 �h�b�� 2004 Apr 15.

Bacteriophage application on red meats and poultry: Effects on Salmonella population in final ground products. Salmonellae can be isolated in the microbiology laboratory using numerous low-selective media (MacConkey agar, deoxycholate agar), intermediate-selective media (Salmonella-Shigella [SS] agar, Hektoen [HE] agar), and highly selective media (selenite agar with brilliant green). However, most clinical laboratories prefer to conduct simple agglutination reactions to antibodies or antisera specific to the somatic O antigens with the intention of grouping Salmonellae into six serogroups, designated A, B, C1, C2, D and E. This grouping system provides valuable information for epidemiological studies and allows genus identification of Salmonella infections (Wattiau et al. [28]. 2000). Salmonellosis is caused by all nontyphoid serotypes of the Salmonella genus except for S typhi and Salmonella paratyphi A, B, and C. Salmonellosis-causing serotypes are isolated from humans and animals, including livestock. Shirakava T, Acarya B, Kinoshita S, Kumagai S, Gotoh A, Kawabata M.

Infants, young children, elderly people and immunocompromised patients are highly susceptible to NTS infections and develop more severe symptoms than normal individuals (Scallan et al.

Salmonella colitis: Assessment with double-contrast barium enema examination in seven patients. DRUG-RESISTANT SALMONELLA FROM ANIMALS FED ANTIMICROBIALS. Children below the age of 5 years, elderly people and patients with immunosuppression are more susceptible to Salmonella infection than healthy individuals. Epidemiological studies show that MDR Salmonella strains cause more severe or prolonged syndromes than susceptible strains, implying that the MDR strains are more virulent than the susceptible ones (Travers & Barza 2002). Gardini G, Zanotti P, Pucci A, Tomasoni L, Caligaris S, Paro B, et al. Based on data from 2005 to 2006 presented by the National Antimicrobial Resistance Monitoring System (NARMS), 84% of clinical isolates of NTS displayed MDR phenotype and 4.1% of the isolates had reduced susceptibility to cephalosporins in the USA. The emergence of Salmonella with antimicrobial resistance is mainly promoted by the use of antibiotics in animal feed to promote the growth of food animals, and in veterinary medicine to treat bacterial infections in those animals (Hyeon et al.

Many Asian countries, including China, India, Vietnam, Pakistan and Indonesia, have high incidence rates of enteric fever, exceeding 100 cases per 100,000 population annually. Virulence factors of salmonellae are complex and encoded both on the organism's chromosome and on large (34-120 kd) plasmids. Enteric fever is characterized by an incubation period of one week or more, with prodomal symptoms such as headache, abdominal pain and diarrhoea (or constipation), followed by the onset of fever (Bhan et al.

The difference in the clinical manifestation is believed to be associated with the presence of the spv (Salmonella plasmid virulence) gene in NTS which causes non-typhoidal bacteraemia, based on genetic analysis (Guiney & Fierer 2011).
