“…Salmonella Enteritidis serovar was found to be predominant from 25.58% to 82.23% of isolates. Similar prevalences of S. Enteritidis isolated from chicken carcasses have been reported previously by the other authors (Machado and Bernado, 1990; Beli et al., 2001; Dominguez and Zumalacarregui, 2002; Capita et al., 2003). However, investigators from Japan (Limawongpranne et al., 1999) detected that Salmonella Blockley, S. Hadar, Salmonella Bredeney were predominant in broilers chickens, meanwhile S. Enteritidis was detected only in 0.9% of samples.…”

We studied serovars of Salmonella strains isolated from chicken and humans in Lithuania over the period from 2000 to 2004. Salmonella strains were isolated and identified according to the techniques recommended by International Organisation for Standardization (Microbiology of Food and Animal Feeding Stuff--Horizontal Method for the Detection of Salmonella, 1998, ISO, Geneva). The per cent of infected flocks with Salmonella in separate years was between 1.01% and 3.2% during the period of investigation. The contamination rate of broiler legs and breasts was higher (2.36% and 4.25%) than that of wings (0.82%). Eighteen serovars of Salmonella were identified from the total 300 isolated samples. The most prevalent serovars in chicken were Salmonella Enteritidis, Salmonella Infantis and Salmonella Typhimurium. Other serovars such as Salmonella Montevideo, Salmonella Djugu, Salmonella Isangi, Salmonella Bovismorbificans, Salmonella Mbankada, Salmonella Hadar were detected only in one to two samples. In general, similar serovars of Salmonella were found in humans and chicken (S. Enteritidis and S. Typhimurium), although distinct serovars were found only in humans or only in chicken. Analysis of the distribution of Salmonella serovars in humans during the seasons of the year indicated that the highest incidence of Salmonella was in Summer and in the beginning of Autumn. Analysis of the distribution of serovars during the study period indicated that there is a shift over time in both humans and chicken.

“…The total rate of Salmonella contamination of broiler carcasses was 11.8%, which is considered high, The Codex Alimentarius established 0% contamination in 25 g of analyzed food, including poultry meat and eggs (Santos et al, 2000). This percentage is lower than that found by Santos et al (2000), with 32% of contamination; by Machado & Bernardo (1990), with 57% of contamination; by Plummer et al (1995), with 23%; and Arvanitidou et al (1998), with 69%. Our results are consistent with the percentage verified by Sharma (1992), with 9.21% of contamination of broiler carcasses.…”

The objective of this research was to isolate and to verify the sensitivity to antimicrobial agents of strains of Salmonella sp. isolated from poultry products in the state of Ceara, Brazil. A total number of 114 samples was collected from 63 broiler carcasses derived from two processing plants and two supermarkets, and 51 excreta samples were collected in broiler farms located in the state of Ceara, which used three live production stages. Each excreta sample consisted of a fresh excreta pool from 100 birds. Samples were submitted to microbiological analyses, and the isolated Salmonella strains were tested for antimicrobial sensitivity. No Salmonella was isolated from excreta samples, while broiler carcass samples showed a high contamination rate of11.8%. Three serotypes were identified: Salmonella enterica serovar Enteritidis, 50%; Salmonella enterica serovar Panama 33%, and Salmonella enterica serovar Newport, 17%. As to the susceptibility tests to antimicrobial agents, 100% of the isolated Salmonella strains showed resistance to Ampicillin and Tetracycline, and sensitivity to Gentamycin, Netilmycin, Carbenicillin, Chloramphenicol.

Monophasic variants of Salmonella Typhimurium‐like strains, lacking the fljB‐encoded second phase H antigen – ie, with the antigenic structure 1,4,[5],12:i:‐ appear to be of increasing importance in many Member States. Such variants are referred to as ‘monophasic S. Typhimurium’. Strains lacking expression of the phase one or both flagellar antigens are also possible, but uncommon. Current standard methods are considered suitable for isolation of such monophasic Salmonella Typhimurium strains. For identification of the monophasic 1,4,[5],12:i:‐ variant, it is advisable to proceed with serotyping until a first negative result of agglutination after flagellar phase inversion, and then apply a PCR protocol in order to confirm the lack of the second phase antigen. To ensure complete consistency of reporting, all isolates of putative Salmonella should be fully serotyped and the full antigenic formula reported. If the full antigenic formula is not available but a phage type that is consistent with S. Typhimurium lacking phase two flagellar antigens has been confirmed, and the lack of the second phase flagellar antigen has been verified by PCR, then the term ‘monophasic S. Typhimurium’ is recommended for reporting purposes in the current situation. On the basis of genetic similarity and ability to obtain a recognised Salmonella Typhimurium phage type, these emerging epidemic monophasic strains with formula 1,4,[5],12:i:‐ are regarded as variants deriving from S. Typhimurium. Moreover, monophasic S. Typhimurium strains have been shown to have similar virulence and antimicrobial resistance characteristics to other strains of S. Typhimurium. Similar to what was observed in the past for epidemic clones of S. Typhimurium, recent studies in numerous countries worldwide confirm the rapid emergence and dissemination of such strains in food animals, companion animals and humans. The public health risk posed by these emerging monophasic S. Typhimurium strains is therefore considered comparable to that of other epidemic S. Typhimurium strains.
