Molecular typing ofStaphylococcus aureusbased on PCR-RFLP ofcoagene and RAPD analysisThe aim of this study was molecular identification ofS. aureusstrains isolated from mastitic milk samples and establishing the genetic relationship between strains isolated from cows belonging to the same herd. In all 43 isolated strains thegapgene (930 bp) was amplified, which enabled their affiliation to theStaphylococcusgenus to be established. PCR-RFLP withAluI endonuclease of thegapgene as well asnuc(450 bp) andcoa(1130 bp) gene amplification allowed preciseS. aureusspecies identification. One hundred percent of the genetic relationship between strains was establishedviaRAPD-PCR and coa-typing.

We report a concurrent case of infection with non-O157 Shiga-toxin-producing Escherichia coli (STEC) strain in an 8-month-old child. Laboratory and epidemiological investigations indicated child exposure to contaminated sheep meat following the Muslim feast of sacrifice (Eid al-Adha). Microbiological and molecular typing confirmed that the ovine strain O52:H45 (stx1+, eae–, hlyA–) was the causal agent. This is the first documented case of human infection to this STEC serotype.

We report an ongoing, protracted and geographically dispersed outbreak of haemolytic uraemic syndrome (HUS) and gastroenteritis in Germany, involving 30 cases since December 2016. The outbreak was caused by the sorbitol-fermenting immotile variant of Shiga toxin-producing (STEC) Escherichia coli O157. Molecular typing revealed close relatedness between isolates from 14 cases. One HUS patient died. Results of a case–control study suggest packaged minced meat as the most likely food vehicle. Food safety investigations are ongoing.

M. gallisepticum infection is a serious economic threat to the poultry industry in India, and the genetic diversity of Indian isolates is unknown. Gene-targeted sequence analysis of M. gallisepticum was conducted for the first time to map the diversity among different Indian isolates from different regions and from different clinical conditions. Sequence analysis of the mgc2 gene grouped the 13 field isolates into four groups. The most prevalent sequence type, the group1 shared 100% identity with the foreign strains THA 3CK08 (Thailand) and UHP1CK99 (Israel). Groups two and three were novel, and were genetically distinct from the strains outside the country. Group four shared 100% similarity with the vaccine strain MG6/85. The nucleotide similarity between the 4 groups ranged from 94.3-99.2%. A PCR-RFLP method using HaeII was tested and validated for its ability to differentiate the Indian field isolates from vaccine strains.
