Decoding the Black Box of Fish Vaccines Efficacy in Basic and Applied Contexts

Reviews in Aquaculture, Volume 18, Issue 4, September 2026.
ABSTRACT Vaccines are the frontline defense in aquaculture, yet predicting their real‐world performance remains a tricky puzzle. Unlike terrestrial veterinary vaccines, fish vaccines largely operate through “Black Box” processes, where we observe the outcomes but rarely understand the underlying immune mechanisms. Laboratory trials, though informative,

EXPERIMENTAL RICKETTSIA TSUTSUGAMUSHI INFECTIONS IN DOGS

Japanese Journal of Medical Science and Biology, 1979
Dogs were infected intravenously and intradermally with the Gilliam and Karp strains of R. tsutsugamushi. Although the development of clinical signs was related to the dose of the organism, Gilliam-infected dogs developed severer infections than those infected with Karp. Specific antibodies were demonstrated in sera of experimentally infected dogs.

Spatial Distribution and Host‐Specific Patterns of Avian Haemosporidian Infections in a Semi‐Arid Region of Northeastern Iran

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
A survey of 263 birds across 10 species in Semnan Province, Iran, revealed a 22.1% prevalence of avian haemosporidian infections, dominated by Haemoproteus spp. Pigeons showed significantly higher infection risk. Spatial analysis identified clustering in Shahroud County, suggesting local climatic and ecological conditions influence parasite ...
