EWA AUGUSTYNOWICZ-KOPEĆ/ IZABELA SIEMION-SZCZEŚNIAK/ ANNA ZABOST/ DOROTA WYROSTKIEWICZ/ DOROTA FILIPCZAK/ KARINA ONISZH/ DARIUSZ GAWRYLUK/ ELŻBIETA RADZIKOWSKA/ DAMIAN KORZYBSKI/ MONIKA SZTURMOWICZ

Abstract Interferon gamma releasing assays (IGRAs) are extensively used in the diagnosis of latent tuberculosis infections. Comparing to tuberculin skin test (TST) they lack false positive results in the populations vaccinated with BCG, and in most non-tuberculous mycobacteria (NTM) infections. Nevertheless, Mycobacterium kansasii, Mycobacterium marinum, and Mycobacterium szulgai may induce positive IGRAs due to RD1 homology with Mycobacterium tuberculosis. The aim of the study was to investigat(..)

Bioactive Compounds of Pseudoalteromonas sp. IBRL PD4.8 Inhibit Growth of Fouling Bacteria and Attenuate Biofilms of Vibrio alginolyticus FB3

NOR AFIFAH SUPARDY/ DARAH IBRAHIM/ SHARIFAH RADZIAH MAT NOR/ WAN NORHANA MD NOORDIN

Abstract Biofouling is a phenomenon that describes the fouling organisms attached to man-made surfaces immersed in water over a period of time. It has emerged as a chronic problem to the oceanic industries, especially the shipping and aquaculture fields. The metal-containing coatings that have been used for many years to prevent and destroy biofouling are damaging to the ocean and many organisms. Therefore, this calls for the critical need of natural product-based antifoulants as a substitute fo(..)

Thermoregulation of Prodigiosin Biosynthesis by Serratia marcescens is Controlled at the Transcriptional Level and Requires HexS

ERIC G. ROMANOWSKI/ KARA M. LEHNER/ NATALIE C. MARTIN/ KRIYA R. PATEL/ JAKE D. CALLAGHAN/ NICHOLAS A. STELLA/ ROBERT M.Q. SHANKS

Abstract Several biotypes of the Gram-negative bacterium Serratia marcescens produce the tri-pyrole pigment and secondary metabolite prodigiosin. The biological activities of this pigment have therapeutic potential. For over half a century it has been known that biosynthesis of prodi giosin is inhibited when bacteria are grown at elevated temperatures, yet the fundamental mechanism underlying this thermoregulation has not been characterized. In this study, chromosomal and plasmid-borne luxCDABE (..)

Clinical Interpretation of Detection of IgM Anti-Brucella Antibody in the Absence of IgG and Vice Versa; a Diagnostic Challenge for Clinicians

REEM AL JINDAN/ NIDA SALEEM/ AAMIR SHAFI/ SHEIKH MUHAMMAD AMJAD

Abstract Non-specific and often misleading clinical presentation of active brucellosis has made it a diagnostic puzzle for treating physicians. Clinicians rely greatly on the detection of IgG and IgM anti-Brucella antibodies by ELISA. Different patterns of positivity have been observed for IgG and IgM anti-Brucella antibodies in different cases, which further increases the risk of an erroneous diagnosis. Detailed herein is our two-years data with varied Brucella serology patterns and their clini(..)

The Influence of Temperature and Nitrogen Source on Cellulolytic Potential of Microbiota Isolated from Natural Environment

AGNIESZKA WITA/ WOJCIECH BIAŁAS/ RADOSŁAW WILK/ KATARZYNA SZYCHOWSKA/ KATARZYNA CZACZYK

Abstract Bacteria from the genus Bacillus are a rich source of commercial enzymes, including amylases, proteases, cellulases, glucose isomerase, and pullulanase. Cellulases account for 15% of the global market of industrial enzymes; thus, new microorganisms producing cellulases in a higher concentration and new ingredients, which can enhance the level of enzyme synthesis, are still needed. Many of cellulose-degrading microorganisms have been isolated so far and characterized in various regions o(..)
