Mosquito‐Borne Diseases in Canada: Integrated Perspectives on Disease Management and Influences of Environmental and Anthropogenic Factors Affecting the Transmission Cycle

open access: yesPublic Health Challenges, Volume 4, Issue 2, June 2025.
ABSTRACT Globally, mosquito‐borne diseases (MBD) cause the highest morbidity and mortality in humans and animals. Currently, in Canada, endemic MBDs that are significant public health problems are all zoonoses and are caused primarily by West Nile virus, Eastern equine encephalitis virus, and Californian serogroup viruses, including the Jamestown ...

Recognition of a second serogroup of Legionella longbeachae [PDF]

open access: yesJournal of Clinical Microbiology, 1981
A strain of Legionella longbeachae (Tucker 1) that was isolated from the postmortem lung tissue of a pneumonia patient was serologically distinct from four other strains of L. longbeachae. The recognition of a second serogroup of L. longbeachae represents the first reported instance of serogroup diversity within a species of Legionella other than L ...

Vibrio cholerae in Water Environments: A Systematic Review and Meta‐Analysis

open access: yesEnvironmental Microbiology Reports, Volume 17, Issue 3, June 2025.
Water facilitates the fecal‐oral transmission of cholera due to the interconnectedness of all water environments. Understanding the current levels of Vibrio cholerae contamination in these water environments is crucial to tackling the ongoing cholera pandemic.

Characterization of Unusual Serogroups of Neisseria meningitidis. [PDF]

open access: yesMicroorganisms
Most cases of invasive meningococcal disease (IMD) in Europe are caused by isolates of the Neisseria meningitidis serogroups B, C, W, and Y. We aimed to explore cases caused by other unusual serogroups. We retrospectively screened IMD cases in the databases of the National Reference Center for Meningococci and Haemophilus influnezae in France between ...

Lower Bird Evenness and Diversity Are Associated With Higher Usutu Prevalence in Culex pipiens Mosquitoes

open access: yesZoonoses and Public Health, Volume 72, Issue 4, Page 359-368, June 2025.
ABSTRACT Introduction The mosquito‐transmitted Usutu virus has spread in the last few years, becoming endemic in several areas of Europe, such as in the southern French region of the Camargue. Our aim was to study the relationships between the presence of the viral agent in Culex mosquitoes and the structure of bird communities in the context of the ...

The solution supramolecular structure of α2 → 8 polysialic acid suggests a structural cause for its low immunogenicity

open access: yesFEBS Letters, Volume 599, Issue 10, Page 1456-1467, May 2025.
α2 → 8 polysialic acid elicits poor immunogenicity. Small‐angle scattering shows a supramolecular structure with parallel‐chain binding, although in different forms at μm and mm calcium. The major histocompatibility complex requires molecular weights around 2000 Da to produce antibodies, and 2000 Da polysialic oligomers will bind in these structures ...

Hemagglutinin Protease HapA Associated With Vibrio cholerae Outer Membrane Vesicles (OMVs) Disrupts Tight and Adherens Junctions

open access: yesJournal of Extracellular Vesicles, Volume 14, Issue 5, May 2025.
ABSTRACT This study explores the virulence mechanisms of Vibrio cholerae, with a particular emphasis on HapA, a zinc metalloprotease delivered via outer membrane vesicles (OMVs). The findings reveal that OMV‐associated HapA disrupts the integrity of tight and adherens junctions in intestinal epithelial cell models more effectively than its purified ...

Impact of the serogroup A meningococcal conjugate vaccine, MenAfriVac, on carriage and herd immunity.

open access: yesClinical Infectious Diseases, 2013
BACKGROUND The conjugate vaccine against serogroup A Neisseria meningitidis (NmA), MenAfriVac, was first introduced in mass vaccination campaigns of 1-29-year-olds in Burkina Faso in 2010. It is not known whether MenAfriVac has an impact on NmA carriage.

Expression and Immunogenicity Analysis of Recombinant Leptospira Interrogans Surface Protein LigA in Mouse Model

open access: yesVeterinary Medicine and Science, Volume 11, Issue 3, May 2025.
Implemented strategies in designing, production, purification and immunogenicity of the recombinant Leptospiral immunoglobulin‐like surface protein‐A (r‐Lig A) as a vaccine candidate. ABSTRACT Background Pathogenic strains of spirochetes of Leptospira spp. cause a globally distributed zoonotic disease called leptospirosis.
