The rise of beef consumption in Indonesia opens an opportunity for “rogue” suppliers to mix beef with other meat species that are relatively cheaper, such as pork, chicken, etc. The aim of this study was to identify pig and chicken meat in raw, cooked, and processed meat products using multiplex-PCR of mitochondrial DNA Cytochrome b gene, which is maternally inherited and widely used for forensic studies. A total of 90 samples-33 raw meats, 33 cooked meats, and 24 meatballs-were used in this study. Each sample was extracted to obtain the DNA genome and this was then amplified using multiplex-PCR. The PCR products were visualized using 2% agarose gel electrophoresis. The results showed that species contained in raw, cooked, and processed meat samples could be identified as indicated by DNA bands at 398, 274, 227, and 157 bp for pig, cattle, chicken, and goat species respectively. This study concluded that species substitution in raw, cooked, and processed meats could be detected using the Cytochrome b gene as a genetic marker through multiplex-PCR assay.

A multiplex PCR assay was evaluated for diagnosis of diarrheagenic Escherichia coli in stool samples of patients with diarrhoea submitted to a diagnostic microbiology laboratory. Two procedures of DNA template preparationproteinase K buffer method and the boiling method were evaluated to examine isolates of E. coli from 150 selected diarrhoeal cases. By proteinase K buffer method, 119 strains (79.3%) of E. coli were characterized to various categories by their genes that included 55.5% enteroaggregative E. coli (EAEC), 18.5% enterotoxigenic E. coli (ETEC), 1.7% enteropathogenic E. coli (EPEC), and 0.8% Shiga toxin-producing E. coli (STEC). Although boiling method was less time consuming (<24 hrs) and less costly (<8.0 US $/ per test) but was less efficient in typing E. coli compared to proteinase K method (41.3% vs. 79.3% ; p<0.001). The sensitivity and specificity of boiling method compared to proteinase K method was 48.7% and 87.1% while the positive and negative predictive value was 93.5% and 30.7%, respectively. The majority of pathogenic E. coli were detected in children (78.0%) under five years age with 53.3% under one year, and 68.7% of the children were male. Children under 5 years age were frequently infected with EAEC (71.6%) compared to ETEC (24.3%), EPEC (2.7%) and STEC (1.4%). The multiplex PCR assay could be effectively used as a rapid diagnostic tool for characterization of diarrheagenic E. coli using a single reaction tube in the clinical laboratory setting.Bangladesh J Med Microbiol 2007; 01 (02): 38-42

ABSTRACT This study aimed to establish a multiplex PCR detection system mediated by “universal primers,” which would be able to determine whether mutton meat contained nonmutton ingredients from rats, foxes, and ducks. Based on the sequence variation of specific mitochondrial genes, nine different multiplex PCR primers were designed, and four kinds of meat products were rapidly identified by electrophoresis using an optimized multiplex PCR system based on the molecular weight differences of the amplified products. Multiplex PCR applications optimized for meat food source from food samples for testing was used to verify the accuracy of the identification method. The results showed that the primers in multiple PCR system mediated by universal primers could be used for the rapid identification of rat, fox, duck, and sheep meat in mutton products, and the detection sensitivity could reach 0.05 ng/μL. The identification of food samples validated the practical value of this method. Therefore, a multiplex PCR system mediated by universal primers was established, which can be used to quickly identify the origin of animal ingredients from rats, foxes, and ducks in mutton products.
