Source: Chen, Y. et. al., Evaluating Virulence and Pathogenesis of Aeromonas Infection in a Caenorhabditis elegans Model. J. Vis. Exp. (2018)This video demonstrates a muscle necrosis assay in C. elegans (Caenorhabditis elegans) using pathogenic Aeromonas strains. By feeding green fluorescent protein (GFP)-expressing worms on Aeromonas-seeded plates, the assay models bacterial infection and reveals tissue damage through fluorescence imaging. The progressive loss of muscle structure and GFP...

This protocol describes the use of sump swabs and sludge analysis of zebrafish systems, which leads to increased detection compared to the sole use of sentinels to detect pathogens such as Aeromonas hydrophila, Mycobacterium spp., and Pseudocapillaria tomentosa. A system to monitor P. tomentosa eggs in quarantine is also proposed.

The larva of the wax moth Galleria mellonella was recently established as an in vivo model to study Legionella pneumophila infection. Here, we demonstrate fundamental techniques to characterize the pathogenesis of Legionella in the larvae, including inoculation, measurement of bacterial virulence and replication as well as extraction and analysis of infected hemocytes.
FAQs
An Aeromonas infection model links bacterial colonization and virulence with the host response. Investigators can examine whether bacteria establish themselves, which virulence factors are associated with disease, how immune responses develop, and whether tissue damage changes as disease progresses. Studying these events together helps connect pathogen behavior to observable outcomes rather than treating each process in isolation.
Researchers can study different Aeromonas strains in comparable experimental systems and assess differences in colonization, virulence, host susceptibility, immune responses, tissue damage, or disease progression. These comparisons can reveal whether strains behave similarly or show distinct disease-associated properties. The approach is useful for relating variation among bacteria to variation in host outcomes.
Host susceptibility helps explain why the same bacterial challenge may not produce identical outcomes across experimental systems. By examining susceptibility alongside colonization, immune responses, tissue damage, and disease progression, investigators can distinguish effects linked to the host from effects linked to bacterial behavior. This makes the model useful for studying host-pathogen interactions under controlled conditions.
Model selection depends on the research question. Cultured cells can support focused examination of interactions between Aeromonas and host cells, whereas aquatic animals or other laboratory hosts can provide information about susceptibility, tissue damage, and disease progression in a more integrated system. Controlled conditions allow investigators to compare findings while matching the host platform to the process under study.
Useful outcomes include observations of bacterial colonization, virulence factors, host immune responses, tissue damage, and disease progression. Together, these findings show how infection develops and how the host responds. The resulting evidence can support comparisons among strains and provide a basis for evaluating potential antimicrobial treatments or preventive strategies.
Beyond basic microbiology, these models connect biology with immunology, ecology, and antimicrobial development. They can clarify host susceptibility, characterize disease-associated bacterial behavior, and test potential treatments or prevention strategies under controlled conditions. Their value lies in linking mechanistic observations to broader questions about pathogen-host relationships and responses to Aeromonas-associated disease.
