Bactericidal Effects Of Chlorine And Bacteriophages On Mycobacteria In Conventionally Treated Water., Max Kevane-Campbell

ORBioM (Open Research BioSciences Meeting)

Introduction

Mycobacteria are members of the order Actinomycetales and the only genus in the family Mycobacteriaceae. The distinguishing characteristics that are found in mycobacteria include acid-fastness and the presence of mycolic acids. Mycobacteria can be commonly classified as non-spore-forming, aerobic, slender rod-shaped, and are slow-growers. Natural reservoirs that mycobacteria can be found in are aquatic and terrestrial environments. Recent studies have shown that mycobacteria that can cause skin lesions, immune and/or pulmonary dysfunctions and chronic diseases, i.e., Mycobacterium avium subsp. Paratuberculosis, M. kansasii, and M. xenopi, can be isolated from common household tap water. Tap water can originate from …

A Tail Of Two Phages: Genomic And Functional Analysis Of Listeria Monocytogenes Phages Vb_Lmos_188 And Vb_Lmos_293 Reveal The Receptor-Binding Proteins Involved In Host Specificity, Aidan Casey, Kieran Jordan, Horst Neve, Aidan Coffey, Olivia Mcauliffe

The physical characteristics of bacteriophages establish them as viable candidates for downstream development of pathogen detection assays and biocontrol measures. To utilize phages for such purposes, a detailed knowledge of their host interaction mechanisms is a prerequisite. There is currently a wealth of knowledge available concerning Gram-negative phage-host interaction, but little by comparison for Gram-positive phages and Listeria phages in particular. In this research, the lytic spectrum of two recently isolated Listeria monocytogenes phages (vB_LmoS_188 and vB_LmoS_293) was determined, and the genomic basis for their observed serotype 4b/4e host-specificity was investigated using comparative genomics. The late tail genes of these …
