Abstract:

The antimicrobial resistance of 122 Shigella sonnei isolates obtained in Korea during the period 1991–2000 was characterized. These isolates were highly resistant to traditional antibiotics such as trimethoprim (100 %), streptomycin (100 %), sulfamethoxazole (94 %), tetracycline (93 %) and nalidixic acid (90 %). All S. sonnei isolates carried Tn7 in their chromosomes. The 8.4 kb non-transferable resistance (R) plasmid carrying tetA, strA-strB and sul1 was found in 93 % of the S. sonnei isolates. Resistance to nalidixic acid first appeared in a S. sonnei isolate in 1997, and then in all S. sonn

ABSTRACT Escherichia coli Sonnei has an O antigen identical to that of Plesiomonas shigelloides O17, and its O-antigen gene cluster is located on a plasmid. By sequencing the chromosomal O-antigen gene cluster of P. shigelloides O17 and comparing it with that of Sonnei, we showed that Sonnei gained its O-antigen genes recently.

Abstract:

Shigella sonnei (S. sonnei) infection accounted for approximately 75% of annual outbreaks of shigellosis, with the vast majority of outbreaks due to the consumption of contaminated foods (e.g., fresh vegetables, potato salad, fish, beef, etc.). Thus, we investigated the antibacterial effect and mechanism of linalool on S. sonnei and evaluated the effect of linalool on the sensory quality of lettuce. The minimum inhibitory concentration (MIC) of linalool against S. sonnei ATCC 25931 was 1.5 mg/mL. S. sonnei was treated with linalool at 1× MIC for 30 min and the amount of bacteria was decreased

This paper presents the genome sequence of a Shigella sonnei mutant strain (S. sonnei 4351) and the effect of mutation in lipopolysaccharide biosynthesis on bacterial fitness.

The mutation results in a lack of epimerization of the core heptose while we also found increased thermosensitivity, abnormal cell division, and increased susceptibility to erythromycin and cefalexin compared to the S. sonnei 4303.

Abstract:

One of the strategies that bacteria utilize to combat environmental stress is to synthesize stress-responding proteins. In Escherichia coli, adverse environmental factors, such as starvation, heat, and the presence of acid, oxidants, heavy metals, and antibiotics, trigger the expression of the universal stress protein (USP). The gene of the USP, uspA, in E. coli K-12 and E. coli O157:H7 has been identified and sequenced. In this study, the nucleotide sequence of uspA in a strain of Shigella sonnei implicated in the 1998 parsley-related outbreak of shigellosis was determined. Within an 800-bp r

Abstract:

Introduction: This study was conducted to determine the prevalence of serotypes, virulence factors, and antimicrobial resistance patterns of Shigella spp. in Beijing, China, from 2004 to 2011. Methodology: Real-time PCR assays were used to detect virulent genes, and the Kirby-Bauer disk diffusion method was used to evaluate antimicrobial resistance. Results: Among the total of 1,652 Shigella isolates, S. sonnei (57.1%) was the predominant species, followed by S. flexneri (42.3%), S. dysenteriae (0.4%), and S. boydii (0.2%). Nineteen serotypes were discovered among S. flexneri strains. The viru

Cetylpyridinium chloride (CPC) activity was quenched with Bacto neutralizing buffer on inoculated cut iceberg lettuce. This protocol permitted comparison of the numbers of Salmonella Gaminara– or Shigella sonnei–inoculated cells on lettuce that survived 1 min of CPC treatment. Cut lettuce was inoculated with about 6 log of Salmonella or 9 log of Shigella and stored in Whirl-Pak bags at 4°C for up to 4 days. Loosely adhered pathogen cells were washed off before CPC treatment. Firmly adhered cells of Salmonella Gaminara or S. sonnei on cut iceberg lettuce survived treatment with CPC even at the

Abstract:

A total of 162 clinical isolates of Shigella collected from children in a semi-rural community of Chile were examined for the presence of genetic determinants of resistance to ampicillin, chloramphenicol, tetracycline, and trimethoprim. Ampicillin resistance was most frequently associated with the presence of blaOXA in S. flexneri and with blaTEM in S. sonnei. The blaOXA gene but not blaTEM was located in class 1 integrons. The dhfrIa gene encoding for resistance to trimethoprim was associated to class 2 integrons and detected exclusively in S. flexneri, whereas dhfrIIIc was found in all S. so

An HIV-1-infected adult presented with a short history of dyspnoea, productive cough and myalgia with fever. Shortly after presentation, he developed the abrupt onset of high-volume watery diarrhoea: stool culture grew Shigella sonnei. At the same time, he became hypoxaemic, and thoracic imaging showed bilateral lower lobe consolidation/collapse. Culture of sputum and blood was negative. The patient recovered with fluid resuscitation and ciprofloxacin monotherapy. This is the first reported case of pneumonia complicating S. sonnei dysentery in an HIV-infected adult.

Introduction: As the overuse of antibiotics increases, antimicrobial resistance is becoming a significant issue, making bacteria resistant to antibiotics and rendering illnesses more challenging to treat. The declining efficacy of synthetic antibiotics in curing infectious diseases is a global concern that is growing. Thus, studies for alternatives from natural plants are in high demand.

Abstract:

ABSTRACT Data suggest that the O-specific polysaccharide (O-SP) domain of the lipopolysaccharide (LPS) of Shigella species is both an essential virulence factor and a protective antigen and that a critical level of serum immunoglobulin G (IgG) to this antigen will confer immunity to shigellosis. Because covalent attachment of polysaccharides to proteins increases their immunogenicity, especially in infants and in young children, the O-SP of Shigella species were bound to medically useful proteins, and the safety and immunogenicity of the resultant conjugates were confirmed in adults and 4- to

ABSTRACT O antigen is part of the lipopolysaccharide present in the outer membrane of gram-negative bacteria. The surface-exposed O antigen is subject to selection by the host immune system, which may account for the maintenance of many different O-antigen forms. Characteristically, all genes specific to O-antigen synthesis are clustered in a region close to the his and gnd genes on the chromosome of Escherichia coli and related species.Shigella sonnei, essentially a clone of E. coli(E. coli clone Sonnei), is an important human pathogen and is unusual in that its O-antigen gene cluster is loca

Since their discovery, antibiotics have been one of the most useful tools in the struggle against infectious disease. However, due to their overuse, numerous pathogens developed multiple resistances against antibiotics. Searching and studying antagonistic GRAS (generally recognized as save) bacteria is a promising field to find innovating treatment against infectious diseases. Lactic acid bacteria and Bifidobacterium are GRAS bacteria well known for their antagonistic effect on other microorganisms including pathogens such as Shigella sonnei.
