“…A similar low percentage of antimicrobial-resistant Salmonella Agona was reported in Finland and Brazil, where > 90% of Salmonella Agona were susceptible to all antimicrobials tested (Lindqvist et al, 2002;Michael et al, 2006). On the other hand, other studies reported a high antimicrobial resistance among this serotype (Zhao et al, 2007;Learn-Han et al, 2008). However, several factors should be taken into account when making such comparisons, including different geographical areas and type of samples.…”

Salmonella enterica serotype Agona (Salmonella Agona) has been among the top 10 serotypes that cause human diarrheal diseases in China. A total of 95 Salmonella Agona (67 from humans, and 28 from animals, food of animal origins, and environmental sources) recovered in Shanghai, China from 2005 to 2011 were subjected to antimicrobial susceptibility testing and molecular subtyping using pulsed-field gel electrophoresis (PFGE). Approximately 68.4% of the Salmonella Agona isolates were pansusceptible to 15 antimicrobial agents tested, and 4 isolates (4.21%) were resistant to at least 3 antimicrobials. PFGE analysis resulted in 41 unique patterns, of which 4 major PFGE patterns (X3, X4, X5, and X6) were grouped together at 96.1% similarity. Isolates of the four patterns included those from food (pork, beef, and chicken) and humans. Our findings showed that the same clones of Salmonella Agona were recovered from human patients and food, and that food of animal origin was potentially a major vehicle of Salmonella Agona in human salmonellosis in Shanghai.

“…The D value of ERIC-PCR fingerprinting was the highest in this study, with 0.9248 at a 65% similarity level (Figure 2). RAPD analysis has achieved excellent results for genomic typing of various microorganisms (de Oliveira et al, 2002;Learn-Han et al, 2008;Nimnoi et al, 2010). Therefore, arbitrary primer OPO 10 was used to fingerprint proteobacterium species isolates in this study.…”

ABSTRACT. Fifty-seven proteobacterium species were successfully isolated from soils of Barrientos Island of the Antarctic using 11 different isolation media. Analysis of 16S rDNA sequencing of these isolates showed that they belonged to eight different genera, namely Bradyrhizobium, Sphingomonas, Methylobacterium, Caulobacter, Paracoccus, Ralstonia, Rhizobium, and Staphylococcus. All isolates were studied for capability of producing antimicrobial and antifungal secondary metabolites using high-throughput screening models. Approximately 23 (13/57) and 2% (1/57) of isolates inhibited growth of Candida albicans ATCC 10231 T and Staphylococcus aureus ATCC 51650 T , respectively. These results indicated that proteobacterium species isolates from Antarctic could serve as potential source of useful bioactive metabolites. Enterobacterial repetitive intergenic consensus (ERIC)-PCR fingerprinting produced nine clusters and 13 single isolates, with a high D value of 0.9248. RAPD fingerprinting produced six clusters and 13 single isolates, with a relatively low D value of 0.7776. ERIC-PCR analysis proved to have better discrimination capability than RAPD analysis and generated better clustering for all proteobacterium species isolates. We conclude that ERIC-PCR is a robust, reliable and rapid molecular typing method for discriminating different genera of proteobacteria.

To date, microbial diversity is still the least well understood component of biodiversity. Bacteria are the most abundant microorganisms where most species are often found ubiquitous. Microorganisms such as bacteria are diverse in their impacts such as in spreading of infectious diseases or play a valuable role in biotechnological purposes. Hence, it is interesting to gain a look upon the ways where bacteria regulate their daily processes in the environment. Bacteria communicate with each other through extracellular signalling molecules or also known as autoinducers (AIs) that are produced, detected and show response. This process is termed as quorum sensing (QS) which indicates that bacteria do communicate in order to perform various physiological activities. QS enable bacteria to have the advantages that are unattainable as individual bacterial cell. This review emphases on the characteristics of quorum sensing (QS) and its benefits in understanding different kind of bacterial QS-dependent activities. This fundamental insight from QS system will enable us to manage bacterial activities by targeting their communication circuit.
