Vibrio campbellii encodes a distinct set of type III secretion system effectors that mediate cytotoxicity in eukaryotic host models

This study identifies four T3SS-secreted effectors in V. campbellii that exhibit cytotoxicity in eukaryotic cells, highlighting conserved T3SS structure but variable effector repertoires across the Harveyi clade.

Choice of host model and manipulated transcription regulator dictates T6SS effector-mediated toxicity

The paper investigates how host model and transcription regulators influence T6SS effector-mediated toxicity in Vibrio proteolyticus, showing host-dependent effector activation and regulation.

Aeromonas adhesins facilitate kin and non-kin attachment to enable T6SS-mediated antagonism in liquid

This study shows marine bacteria use T6SS to compete in liquid by aggregating via adhesins, challenging the assumption that T6SS activity is limited to solid surfaces.

Assessing toxicity and competitive fitness of vibrios isolated from coastal waters in Israel

The paper assesses the pathogenic potential of Vibrio isolates from Israel's coastal waters, finding toxin diversity, immune cell toxicity, and antibiotic resistance.

A T6SS in the coral pathogen Vibrio coralliilyticus secretes an arsenal of anti-eukaryotic effectors and contributes to virulence

This study identifies two temperature-regulated T6SSs in Vibrio coralliilyticus, revealing their roles in bacterial competition and host toxicity, with T6SS2 secreting nine novel anti-eukaryotic toxins.
