The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

FEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Investigation of in vitro Mineral Forming Bacterial Isolates from Subgingival Calculus

Archives of Clinical and Experimental Surgery, 2014
The mechanism that dictates the formation of dental calculus, an important component of periodontal health, has yet to be sufficiently explained. The effect of bacterial flora on dental calculus formation is important for periodontal status.

Role of glucose and CcpA in capsule expression and virulence of Streptococcus suis [PDF]

, 2011
Streptococcus suis is one of the most important pathogens in pigs and is also an emerging zoonotic agent. After crossing the epithelial barrier, S. suis causes bacteraemia, resulting in meningitis, endocarditis and bronchopneumonia.

L‐aspartate oxidase provides new insights into fumarate reduction in anaerobic darkness in Synechocystis sp. PCC6803

FEBS Letters, EarlyView.
Synechocystis strains deficient in succinate dehydrogenase (SDH) secrete more succinate than the WT under dark anaerobic conditions, supporting that SDH then primarily acts as SDH, not as a fumarate reductase. L‐aspartate oxidase (Laspo) from Synechocystis is functional under anaerobic conditions, reducing fumarate to succinate.

FATAL GROUP A STREPTOCOCCAL TOXIC SHOCK-LIKE SYNDROME IN A CHILD WITH VARICELLA: REPORT OF THE FIRST WELL DOCUMENTED CASE WITH DETECTION OF THE GENETIC SEQUENCES THAT CODE FOR EXOTOXINS SPE A AND B, IN SÃO PAULO, BRAZIL

Revista do Instituto de Medicina Tropical de São Paulo, 1999
A previously healthy seven-year-old boy was admitted to the intensive care unit because of toxaemia associated with varicella. He rapidly developed shock and multisystem organ failure associated with the appearance of a deep-seated soft tissue infection ...

Determination of Certain Immunological and Physicochemical Features of Pneumococcal Surface Protein A (PspA): In-silico Cloning of pspA [PDF]

Modern Medicine
Objective: Pneumococcal surface protein A (PspA) is present in almost all strains of pneumococci and is highly immunogenic, stimulating the production of antibodies. It has a role in pneumococcal pathogenicity.

A longitudinal study of natural infection of piglets with Streptococcus suis types 1 and 2 [PDF]

, 1991
Streptococcus suis types 1 and 2 were detected in nasal swabs taken from five litters of piglets sampled twice weekly from birth. The two types had been detected in all pigs by the time they were 38 and 25 days old respectively with mean ages of first ...

Metastatic niche shaped by host factors influences disseminated cancer cell fate

FEBS Letters, EarlyView.
Metastasis is shaped not only by cancer cells but also by the environments they encounter. This review explores how factors such as aging, diet, the microbiome, lifestyle, and environmental exposures remodel organ‐specific niches in the lung, liver, bone, and brain, influencing where metastatic cells survive, remain dormant, or grow, and ultimately ...

Group B Streptococcus maternal colonization and neonatal sepsis in Belgium between 2012 and 2021: a description of the epidemiological situation and identification of risk factors

BMC Pregnancy and Childbirth
Background Group B Streptococcus (GBS) infection is a leading cause of neonatal morbidity. Maternal rectovaginal GBS colonization is a primary risk factor for early onset neonatal GBS infection. In Belgium, pregnant women are screened and, if positive or
