is a leading cause of dysentery worldwide, responsible for up to 165 million cases of shigellosis each year. is also recognised as an exceptional model pathogen to study key issues in cell biology and innate immunity. Several infection models have been useful to explore biology; however, we still lack information regarding the events taking place during the infection process Here, we discuss a selection of mechanistic insights recently gained from studying infection of zebrafish (), with a focus on cytoskeleton rearrangements and cellular immunity. We also discuss how infection of zebrafish can be used to investigate new concepts underlying infection control, including emergency granulopoiesis and the use of predatory bacteria to combat antimicrobial resistance. Collectively, these insights illustrate how infection of zebrafish can provide fundamental advances in our understanding of bacterial pathogenesis and vertebrate host defence. This information should also provide vital clues for the discovery of new therapeutic strategies against infectious disease in humans.

Infections of multidrug-resistant pathogens including Pseudomonas aeruginosa, cause a high risk of mortality in immunocompromised patients and underscore the need for novel natural antibacterial drugs. In this study, common phytochemicals prevalent in fruits and vegetables have been demonstrated for their ability to inhibit quorum sensing (QS) in Pseudomonas aeruginosa PAO1 (PA). Ten compounds were screened virtually by molecular docking, among which, daidzein dimethyl ether originally from Albizzia lebbeck showed the most significant inhibitory effect on the formation of biofilm and the accumulation of virulence factors, including elastase, pyocyanin and rhamnolipid in PA.

Recently, 3-D porous architecture of the composites play a key role in cell proliferation, bone regeneration, and anticancer activities. The osteoinductive and osteoconductive properties of β-TCP allow for the complete repair of numerous bone defects. Herein, β-TCP was synthesized by wet chemical precipitation route, and their 3-D porous composites with HBO and Cu nanoparticles were prepared by the solid-state reaction method with improved mechanical and biological performances.

The Rift Valley fever virus (RVFV) causes haemorrhagic fever, encephalitis, and permanent blindness and has been listed by the WHO as a priority pathogen. To study RVFV pathogenesis and identify small-molecule antivirals, we established a novel In Vivo model using zebrafish larvae. Pericardial injection of RVFV resulted in ~4 log viral RNA copies/larva, which was inhibited by the antiviral 2'-fluoro-2'-deoxycytidine.

, the etiological agent of Chagas disease, is a parasite known for its diverse genotypic variants, or Discrete Typing Units (DTUs), which have been associated with varying degrees of tissue involvement. However, aspects such as parasite attachment remain unclear. It has been suggested that the TcI genotype is associated with cardiac infection, the most common involved site in chronic human infection, while TcII is associated with digestive tract involvement.

Cholera is a diarrheal disease prevalent in populations without access to clean water. Cholera is caused by which colonizes the upper small intestine in humans once ingested. A growing number of studies suggest that the gut microbiome composition modulates animal behavior.
