Targeting caspases in intracellular protozoan infections

, 2009
Caspases are cysteine aspartases acting either as initiators (caspases 8, 9, and 10) or executioners (caspases 3, 6, and 7) to induce programmed cell death by apoptosis. Parasite infections by certain intracellular protozoans increase host cell life span

Dual Host–Pathogen Screening of the Lung During Severe Influenza Using Spatial Transcriptomics

Immunology &Cell Biology, EarlyView.
We performed genome‐wide spatial transcriptomics at 10 μm resolution on the lungs of mice infected with influenza A virus. We utilised publicly available scRNAseq reference datasets to identify cell types present. We found viral transcripts across all detected cell types, suggesting localised indiscriminate infection.

Lymphocystis Disease in Endemic Aotearoa New Zealand Bully (Gobiomorphus cotidianus)

Journal of Fish Diseases, EarlyView.
ABSTRACT We detected lymphocystis disease virus (LCDV) for the first time in an Aotearoa New Zealand freshwater environment, from an individual common bully, toitoi, Gobiomorphus cotidianus (Eleotridae). Dinah's bully, Gobiomorphus dinae, and Kaharore bully, Gobiomorphus mataraerore, also exhibited gross nodular lesions on the fins but were not sampled.

Francisella orientalis in Aquacultured Tilapia (Oreochromis spp.): A Case Work‐Up of Diagnostics and Pathologic Findings in the North Central Region (USA)

Journal of Fish Diseases, EarlyView.
ABSTRACT Tilapia (Oreochromis spp.) is an increasingly popular aquacultured fish worldwide. While tilapia enjoy a ‘hardy‐fish’ reputation among fish farmers, they are susceptible to a variety of infectious diseases that can be difficult to recognize pondside and have similarities in their gross presentations. This report describes gross and microscopic
