Replication of plasmids derived from Shiga toxinconverting bacteriophages in starved Escherichia coli [PDF]

, 2011
The pathogenicity of Shiga toxin-producing Escherichia coli (STEC) depends on the expression of stx genes that are located on lambdoid prophages. Effective toxin production occurs only after prophage induction, and one may presume that replication of the

Gas phase characterization of the noncovalent quaternary structure of Cholera toxin and the Cholera toxin B subunit pentamer [PDF]

, 2006
Cholera toxin (CTx) is an AB5 cytotonic protein that has medical relevance in cholera and as a novel mucosal adjuvant. Here, we report an analysis of the noncovalent homopentameric complex of CTx B chain (CTx B5) using electrospray ionization triple ...

Multimodal targets of (‐)‐α‐thujone mediating avoidance behavior of a stored‐products pest, Tribolium castaneum, in response to irritant stimuli

Pest Management Science, EarlyView.
We identified four kinds of target molecules against (‐)‐α‐thujone associating avoidance behavior in Tribolium castaneum, indicating multimodality. Abstract BACKGROUND The reciprocal evolutionary processes among phytophagous insects and host plants involve host shift in the herbivorous insects in response to defense chemicals, such as plant‐derived ...

Use of Genomics to Investigate Historical Importation of Shiga Toxin–Producing Escherichia coli Serogroup O26 and Nontoxigenic Variants into New Zealand

Emerging Infectious Diseases, 2019
Shiga toxin–producing Escherichia coli serogroup O26 is an important public health pathogen. Phylogenetic bacterial lineages in a country can be associated with the level and timing of international imports of live cattle, the main reservoir.

Nanobodies as next‐generation targeting platforms: From discovery technologies to translational biomedicine

VIEW, EarlyView.
Nanobodies, derived from the variable domains of camelid heavy‐chain‐only antibodies, have emerged as transformative biomedical tools due to their nanoscale size, exceptional stability, and unique capacity to recognize cryptic epitopes. This review provides a comprehensive overview of the field, outlining the structural and biochemical features of ...

Prevalence and Genomic Characterization of mcr‐Positive Enterobacteriaceae in Retail Meat in Thailand Following the Colistin Ban

Microbiology and Immunology, EarlyView.
ABSTRACT This study aimed to investigate the prevalence and characteristics of mcr‐positive Enterobacteriaceae in retail meat in Thailand following the national ban on prophylactic colistin use in food producing animals. A total of 152 meat samples (103 chicken and 49 pork) were collected from supermarkets and open markets between July and September ...

Inborn errors of immunity in children with neuroinflammation

Developmental Medicine &Child Neurology, EarlyView.
Abstract Inborn errors of immunity (IEIs), an expanding group of monogenic disorders with diverse clinical manifestations, are increasingly recognized to include neuroinflammatory disease. Examples of diseases included under this umbrella are Aicardi–Goutières syndrome, deficiency of adenosine deaminase 2, familial haemophagocytic lymphohistiocytosis ...

Influence of the Escherichia coli oxyR gene function on lambda prophage maintenance [PDF]

, 2010
In Escherichia coli hosts, hydrogen peroxide is one of the factors that may cause induction of lambda prophage. Here, we demonstrate that H2O2-mediated lambda prophage induction is signiWcantly enhanced in the oxyR mutant host. The mRNA levels for cI
