Multiple Key Hosts and Network Structure Shape Viral Prevalence Across Multispecies Communities of Bees

open access: yesEcology Letters, Volume 29, Issue 2, February 2026.
This study develops a quantitative framework that integrates field data, epidemiological models, simulations, and Bayesian inference to identify key viral hosts in multispecies bee communities. By estimating species‐specific R0 values from flower‐visitor networks and viral screening, we show that honeybees, as well as other wild bees, can drive the ...

Understanding Measles Contagion: A Fractional‐Order Model With Stability and Sensitivity Insights

open access: yesJournal of Mathematics, Volume 2026, Issue 1, 2026.
In this paper, we propose an epidemiological mathematical model described by a system of nonlinear differential equations of fractional order (FODEs). Specifically, we employ the Caputo fractional derivative (CFD). Our analysis verifies the existence of a solution.

Towards Integrated Surveillance of Marine Brucellosis: Diagnostic and Phylogenetic Assessment of Brucella ceti in Stranded Dolphins of the Western Mediterranean Sea

open access: yesTransboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Reports of brucellosis in free‐ranging cetaceans are increasing worldwide, particularly in the Mediterranean Sea. To enhance diagnostic accuracy and epidemiological understanding of cetacean brucellosis in the Western Mediterranean Sea, we analyzed bacteriological, serological, and molecular data from 30 cetaceans belonging to three different species ...

Rescue, rehabilitation, and release of marine mammals: An analysis of current views and practices. [PDF]

open access: yes, 1996
Stranded marine mammals have long attracted public attention. Those that wash up dead are, for all their value to science, seldom seen by the public as more than curiosities.

Phocine distemper Virus: Current knowledge and future directions [PDF]

open access: yes, 2014
Phocine distemper virus (PDV) was first recognized in 1988 following a massive epidemic in harbor and grey seals in north-western Europe. Since then, the epidemiology of infection in North Atlantic and Arctic pinnipeds has been investigated.

Seroprevalence and Associated Risk Factors of Peste des Petits Ruminants Virus in Small Ruminants of Punjab, Pakistan

open access: yesTransboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Peste des petits ruminants (PPR) is a highly contagious viral disease prevalent in sheep and goats, and causes significant economic losses. The study was conducted in 2024 in Punjab Province, Pakistan, to estimate the seroprevalence of the PPR virus (PPRV) and to analyze animal‐level risk factors in unvaccinated small ruminants. Over a 12‐month period,

Peste des petits ruminants virus virulence is associated with an early inflammatory profile in the tonsils and cell cycle arrest in lymphoid tissue

open access: yesMicrobiology Spectrum
Using a systems immunology approach, this study comprehensively explored the immunopathogenesis of peste des petits ruminants (PPR) focussing on strain-dependent differences in virulence.

Immunodeficiencies caused by infectious diseases. [PDF]

open access: yes, 2010
Immunodeficiencies caused by infectious agents may result from disruption of normal host barriers or dysregulation of cellular immunity, the latter serving to promote survival of the infectious agent through immune evasion.

Analysing Spatiotemporal Characteristics and Estimating the Spatial Distribution of Peste des Petits Ruminants (PPR) in Africa

open access: yesTransboundary and Emerging Diseases, Volume 2026, Issue 1, 2026.
Peste des petits ruminants (PPR) is a highly contagious disease that primarily affects small ruminants such as sheep and goats. Since first emerging in Africa, it has rapidly spread throughout the continent, causing significant mortality and posing a serious threat to livestock production and food security. In this study, we integrated diverse datasets
