Real Time Observation of Neutrophil White Blood Cell Recruitment to Bacterial Infection In Vivo
The zebrafish (Danio rerio) is an emerging vertebrate model organism to study infection. The transparent larva comprises a fully functional innate immune system and enables live imaging of fluorescent…Read article
Five Big Mysteries about CRISPR’s Origins
Francisco Mojica was not the first to see CRISPR, but he was probably the first to be smitten by it. He remembers the day in 1992 when he got his first glimpse of the microbial immune system that…Read article
Correlative Cryo-Fluorescence and Cryo-Scanning Electron Microscopy as a Straightforward Tool to Study Host-Pathogen Interactions
Correlative light and electron microscopy is an imaging technique that enables identification and targeting of fluorescently tagged structures with subsequent imaging at near-to-nanometer resolution.…Read article

Contributions of Microbiome and Mechanical Deformation to Intestinal Bacterial Overgrowth and Inflammation in a Human Gut-on-a-Chip
A human gut-on-a-chip microdevice was used to coculture multiple commensal microbes in contact with living human intestinal epithelial cells for more than a week in vitro and to analyze how gut…Read article
Video Talk: CRISPR-Cas – From a Bacterial Adaptive Immune System to a Genome Engineering Tool
The CRISPR-Cas system was originally discovered as an adaptive immune system of bacteria and archaea to protect against viral attack. During this talk, given at Leica Microsystems in Wetzlar, Dr.…Read article
Imaging of Host Cell-bacteria Interactions using Correlative Microscopy under Cryo-conditions
Pathogenic bacteria have developed intriguing strategies to establish and promote infections in their respective hosts. Most bacterial pathogens initiate infectious diseases by adhering to host cells…Read article
Infection of Zebrafish Embryos with Intracellular Bacterial Pathogens
Transparent zebrafish embryos have proved useful model hosts to visualize and functionally study interactions between innate immune cells and intracellular bacterial pathogens, such as Salmonella…Read article
Transmission Electron Microscopy Sample Preparation Protocols for the Ultrastructural Study of Cysts of Free-living Protozoa
Cysts of free-living protozoa have an impact on the ecology and epidemiology of bacteria because they may act as a transmission vector or shelter the bacteria against hash environmental conditions.…Read article
Influencing Factors and Applicability of the Viability EMA-qPCR for a Detection and Quantification of Campylobacter Cells from Water Samples
In recent years, increasing numbers of human campylobacteriosis cases caused by contaminated water have been reported. As the culture-based detection of Campylobacter is time consuming and can yield…Read article
Analysis of Autofluorescence in Polymorphonuclear Neutrophils: A New Tool for Early Infection Diagnosis
Diagnosing bacterial infection (BI) remains a challenge for the attending physician. An ex vivo infection model based on human fixed polymorphonuclear neutrophils (PMNs) gives an autofluorescence…Read article
