Abstract:

ABSTRACT Exposure to bile induces curing of the virulence plasmid in Salmonella enterica serovar Typhimurium (pSLT). Disruption of the ccdB gene increases pSLT curing, both spontaneous and induced by bile, suggesting that the pSLT ccdAB genes may encode a homolog of the CcdAB addiction module previously described in the F sex factor. Unlike the F sex factor, synthesis of pSLT-encoded pili does not confer bile sensitivity. These observations may provide insights into the evolution of virulence plasmids in Salmonella subspecies I, as well as the causes of virulence plasmid loss in other Salmonel

ABSTRACT pUO-StVR2 is a virulence-resistance plasmid which originated from pSLT of Salmonella enterica serovar Typhimurium through acquisition of a complex resistance island, flanked by regions that provide a toxin-antitoxin system and an iron uptake system.

Abstract:

Abstract DNA adenine methylase mutants of Salmonella typhimurium contain reduced amounts of FinP, an antisense RNA encoded by the virulence plasmid pSLT. Lowered FinP levels are detected in both Dam- FinO+ and Dam- FinO- backgrounds, suggesting that Dam methylation regulates FinP production rather than FinP half-life. Reduced amounts of F-encoded FinP RNA are likewise found in Dam- mutants of Escherichia coli. A consequence of FinP RNA scarcity in the absence of DNA adenine methylation is that Dam- mutants of both S. typhimurium and E. coli show elevated levels of F plasmid transfer. Inhibitio

Abstract:

Let G be a finite group. The prime graph of G is denoted by ?(G). We prove that the simple group PSLn(3), where n ? 9, is quasirecognizable by prime graph; i.e., if G is a finite group such that ?(G) = ?(PSLn(3)), then G has a unique nonabelian composition factor isomorphic to PSLn(3). Darafsheh proved in 2010 that if p > 3 is a prime number, then the projective special linear group PSLp(3) is at most 2-recognizable by spectrum. As a consequence of our result we prove that if n ? 9, then PSLn(3) is at most 2-recognizable by spectrum.

Horizontal gene transfer via plasmid conjugation is a major driving force in microbial evolution but constitutes a complex process that requires synchronization with the physiological state of the host bacteria.

We describe a posttranscriptional mechanism whereby the Hfq-dependent small RNA, RprA, inhibits transfer of pSLT, the virulence plasmid of Salmonella enterica.

Thus, the shared FinO domain might bear an unusual plasticity enabling it to act either selectively or promiscuously on the same cellular RNA pool.

Abstract:

Introduction: Pseudomonas aeruginosa is an important opportunistic pathogen associated with majority of the hospital-acquired infections in immunocompromised patients, worldwide. Biofilms formed by this bacterium increase its resistance toward antibiotics, which in turn increase morbidity and mortality. As environmental isolates of P. aeruginosa are also capable of producing virulence-associated traits, they can be considered as potential pathogens. Materials and Methods: This study was undertaken to compare the expression of some of the biofilm genes such as algD, pslA, pslB, pelA, and pelD i

Abstract The complete amino acid sequence of five light chain variable (V) regions of human monoclonal IgM kappa rheumatoid factors (RF) was determined, and their cross-reactive idiotypes (CRI) were characterized with antibodies induced by immunization with synthetic peptides PSL2 and PSL3, corresponding to the second and third complementarity-determining regions (CDR) of the SIE light chain. Together with two additional RF studied previously, all seven RF belong to the V kappa IIIb sub-subgroup. The region encoded by the V kappa gene segment (positions 1 to 95) in all seven proteins was virtu

Abstract:

AbstractIn the present paper we completely describe the isomorphisms between projective elementary groups PSLn and PSLm (n ≥ 2, m ≥ 2) over division rings. It was found that such groups can be isomorphic only if n = m; the division rings are isomorphic or anti-isomorphic, except for the following groups:PSL(2,F7) and PSL(3,F2); PSL(2, F4) and PSL(2,F5).The idea is based on a deepening of the classical Hua's approach.

Abstract:

Background: Pseudomonas aeruginosa is one of the most common Gram-negative bacteria responsible for outbreaks of infection and morbidity in hospitals. The difficulty in treating them lies in their possession of a wide range of virulence factors in addition to their ability to have natural and acquired resistance to antibiotics especially the multi-drug resistance (MDR) ones. Material and Methods: 114 samples were collected and isolated from burns and wounds patients hospitalized in Baquba Teaching Hospital, during the period from September to December 2022. These isolates were diagnosed using

Abstract:

Salmonella enterica subspecies enterica serovar 4,[5],12:i:- is a monophasic variant of S. Typhimurium which has emerged as a world-wide distributed pathogen in the last decades. Several clones have been identified within this variant, the European clone, the Spanish clone, the Southern European clone and the U.S./American clone. The present study focused on isolates of the Southern European clone that were obtained from clinical samples at Spanish hospitals. The selected isolates were multidrug resistant, with most resistance genes residing on IncR plasmids that also carried virulence genes.

The gastrointestinal tracts of animals like pigs, poultry or cattle are the main reservoirs of Salmonella serotypes. Guinea pig meat is an important protein source for Andean countries, but this animal is commonly infected by S. Typhimurium, producing high mortality rates and generating economic losses. Despite its impact on human health, food security, and economy, there is no genomic information about the S. Typhimurium responsible for the gui

Background: Scientific literature is completely devoid of full and clear morphological description of changes in Thoracic Vertebrae (TV) under the effect of full Thoracic Traction (TT), because of the absence of any direct method that can achieve full TT as it exists in Lumbar vertebrae (LV) and Cervical vertebrae (CV). Therefore, it is necessary to create a method that can achieve full TT in order to obtain a clear scientific morphological description of changes in Intervertebral Spaces (IS) at TV: anterior, posterior and central heights, and also anterior/ posterior ratio (A/p) ratio.

Abstract:

The factorization of groups into a Zappa–Szép product, or more generally into a k-fold Zappa–Szép product of its subgroups, is an interesting problem, since it eases the multiplication of two elements in a group and has recently been applied to public-key cryptography. We provide a generalization of the k-fold Zappa–Szép product of cyclic groups, which we call OGS decomposition. It is easy to see that the existence of an OGS decomposition for all the composition factors of a non-abelian group G implies the existence of an OGS for G itself. Since the composition factors of a soluble group are c
