  • Final Report
    Final Report Study of glutamate decarboxylase gene from GABA-producing lactic acid bacteria isolated from Kung-Som, the traditional Thai fermented shrimp Investigator Suppasil Maneerat Department of Industrial Biotechnology Faculty of Agro-Industry Prince of Songkla University This research project was supported by Prince of Songkla University, Thailand, for the fiscal year of 2013-2014 (Grant No. AGR560008S) 2015 i ACKNOWLEDGEMENTS This study was financially supported by Prince of Songkla University, Thailand, for the fiscal year of 2013-2014 (Grant No. AGR560008S). Suppasil Maneerat ii ABSTRACT Kung-Som is one of several traditional Thai fermented shrimp products, especially popular in the southern part of Thailand. This is the first report to reveal the bacterial communities in the finished product of Kung-Som. Ten Kung-Som samples were evaluated using the polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) methodology combined with appropriated primers to study the dynamics of the bacterial population. Two primers sets (V3; 341f(GC)-518r and rpoB; rpoB1698f(GC)-rpoB2014r primers) were considered as a possible tool for study the communities of bacteria. PCR- DGGE analysis of both the V3-region and rpoB amplicon was successfully applied to discriminate between lactic acid bacteria (LAB) and other Gram positive strains in the bacterial communities of Kung-Som products. These preliminary results concluded that the main microbiology of finished product of Kung-Som was LAB and coagulase negative cocci (CNC). Kung-Som presents a high glutamic acid which is a major substrate for biosynthesis of natural γ-aminobutyric acid (GABA) by LAB. The GABA-producing LAB from Kung- Som products were isolated, screened and identified.

  • The Novel Macrolide Resistance Genes Mef(F) and Msr(G)
    J Antimicrob Chemother 2021; 76: 48–54 doi:10.1093/jac/dkaa405 Advance Access publication 29 October 2020 The novel macrolide resistance genes mef(F) and msr(G) are located on a plasmid in Macrococcus canis and a transposon in Macrococcus caseolyticus Downloaded from https://academic.oup.com/jac/article/76/1/48/5942709 by Universitaetsbibliothek Bern user on 01 March 2021 Javier Eduardo Fernandez, Vincent Perreten* and Sybille Schwendener Institute of Veterinary Bacteriology, Vetsuisse Faculty, University of Bern, Bern, Switzerland *Corresponding author. E-mail: [email protected] Received 18 May 2020; accepted 1 September 2020 Objectives: To analyse macrolide resistance in a Macrococcus canis strain isolated from a dog with an ear infec- tion, and determine whether the resistance mechanism is also present in other bacteria, and associated with mobile genetic elements. Methods: The whole genome of M. canis Epi0082 was sequenced using PacBio and Illumina technologies. Novel macrolide resistance determinants were identified through bioinformatic analysis, and functionality was dem- onstrated by expression in Staphylococcus aureus. Mobile genetic elements containing the novel genes were analysed in silico for strain Epi0082 as well as in other bacterial strains deposited in GenBank. Results: M. canis Epi0082 contained a 3212 bp operon with the novel macrolide resistance genes mef(F) and msr(G) encoding a efflux protein and an ABC-F ribosomal protection protein, respectively. Cloning in S. aureus confirmed that both genes individually confer resistance to the 14- and 15-membered ring macrolides erythromycin and azithromycin, but not the 16-membered ring macrolide tylosin. A reduced susceptibility to the streptogramin B pristinamycin IA was additionally observed when msr(G) was expressed in S.

Airy, MD Web Policies and Links Table of Contents Introduction Acknowledgments About this Document Bibliography Selected Web Resources The South American Camelids: Llamas, Alpacas, Guanacos, and Vicunas 1943-2006 Introduction The Camelidae family consists of a small family of mammalian animals. There are two members of Old World camels living in Africa and Asia--Arabian and the Bactrian, and four members of the New World camels living in South America--the llamas, vicunas, alpacas and guanacos. They are all very well adapted to their respective environments: the camels in harsh deserts of Africa and Asia; and their South American cousins inhabit the high altiplano and bush area of South America. Most of these species have been integrated into, and play very important roles in lives of the indigenous people. They have been traditionally used for transport of people and things, hides and fibers for clothing and other textile articles, and in many cases they supply meat and milk products, etc. The South American species are being raised in non-native countries for a variety of reasons: as pack animals, pets, guard animals for sheep ranges, and for fiber.

Seven tick species are known to feed on bare- nosed wombats (Vombatus ursinus), in addition to the highly prevalent Sarcoptes scabiei mite which causes fatal sarcoptic mange in most bare-nosed wombat populations. Little is known about the pathogens carried by most wombat ticks or how they impact wombats affected by sarcoptic mange. Methods Wombat ticks were sourced from wildlife hospitals and sanctuaries across Australia and identied to species level using taxonomic keys. Genomic DNA (gDNA) was extracted from a subsample, and following the amplication of the bacterial 16S rRNA gene V3-V4 hypervariable region, next generation sequencing (NGS) on the Illumina MiSeq platform was used to assess the microbial composition. Results A total of 447 tick specimens were collected from 47 bare-nosed wombats between January 2019 and January 2020.
