Phages differ substantially in the bacterial hosts that they infect. Their host range is
determined by the specific structures that they use to target bacterial cells. Tailed phages …

The life of bacteria is challenging, to endure bacteria employ a range of mechanisms to
optimize their environment, including deploying the type VI secretion system (T6SS). Acting …

Bacterial pathogens utilize a myriad of mechanisms to invade mammalian hosts, damage
tissue sites, and evade the immune system. One essential strategy of Gram-negative …

Bacteria need to deliver large molecules out of the cytosol to the extracellular space or even
across membranes of neighboring cells to influence their environment, prevent predation …

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 …

Acinetobacter baumannii has emerged as an important nosocomial pathogen, particularly
for patients in intensive care units and with invasive indwelling devices. The most recent …

Contractile injection systems mediate bacterial cell-cell interactions by a bacteriophage tail–
like structure. In contrast to extracellular systems, the type 6 secretion system (T6SS) is …

The t ype VI s ecretion s ystem (T6SS) is a widespread protein export apparatus found in
Gram-negative bacteria. The majority of T6SSs deliver toxic effector proteins into competitor …

The type VI secretion system (T6SS) primarily functions to mediate antagonistic interactions
between contacting bacterial cells, but also mediates interactions with eukaryotic hosts. This …
