BACKGROUND Microbial communities are ubiquitous on Earth. The microbiota of different
habitats are diverse and have distinct functional traits, but there are common ecological …

The gut microbiota, a complex ecosystem of microorganisms of different kingdoms, impacts
host physiology and disease. Within this ecosystem, inter-bacterial interactions and their …

The type VI secretion system (T6SS) is crucial in interbacterial competition and is a virulence
determinant of many Gram-negative bacteria. Several T6SS effectors are covalently fused to …

All bacteria must compete for growth niches and other limited environmental resources.
These existential battles are waged at several levels, but one common strategy entails the …

Contact-dependent growth inhibition (CDI) entails receptor-mediated delivery of CdiA-
derived toxins into Gram-negative target bacteria. Using electron cryotomography, we show …

Bacteriophages (phages) are being considered as alternative therapeutics for the treatment
of multidrug resistant bacterial infections. Considering phages have narrow host-ranges, it is …

Acinetobacter baumannii is a notorious pathogen that has emerged as a healthcare
nightmare in recent years because it causes serious infections that are associated with high …

Infections led by Acinetobacter baumannii strains are of great concern in healthcare
environments due to the strong ability of the bacteria to spread through different apparatuses …

Contact-dependent growth inhibition (CDI) is a widespread form of inter-bacterial
competition mediated by CdiA effector proteins. CdiA is presented on the inhibitor cell …

The type VI secretion system (T6SS) is an antibacterial weapon that is used by numerous
Gram-negative bacteria to gain competitive advantage by injecting toxins into adjacent prey …
