Summary
Mosquitoes like Culex pipiens and Aedes albopictus carry viruses and parasites. This study monitored mosquito populations and pathogens in Italy and Crete, finding different viruses and nematodes in each region.
Area of Science:
- Environmental science
- Medical entomology
- Pathogen surveillance
Background:
- Urbanization drives changes in mosquito populations and vector-borne disease transmission.
- Culex pipiens and Aedes albopictus are significant vectors of arboviruses and filarial parasites in human-altered environments.
Purpose of the Study:
- To conduct a comparative entomological and pathogen surveillance in central Italy and Crete.
- To assess mosquito species composition, population dynamics, and arbovirus/filarial nematode circulation across different ecological contexts.
- To understand the influence of environmental drivers on mosquito communities and pathogen circulation.
Main Methods:
- Comparative entomological and pathogen surveillance conducted between 2022 and 2023.
- Mosquito collection and identification, focusing on species composition and population dynamics.
- Molecular screening for arboviruses (Usutu virus, West Nile virus) and filarial nematodes (Setaria, Dirofilaria repens).
Main Results:
- In Italy, Culex pipiens (~86%) and Aedes albopictus (~12%) dominated; Usutu virus and Setaria nematodes co-circulated in 2022. In 2023, West Nile virus Lineage 2 and Usutu virus co-circulated in Culex pipiens.
- In Crete, Culex species were dominant, with highest biodiversity in peri-urban areas. Dirofilaria repens was detected in Aedes albopictus; no West Nile virus or Usutu virus circulation was found.
- Significant temporal variations in mosquito diversity and frequency were observed in both regions.
Conclusions:
- Integrated, region-specific surveillance is crucial for understanding vector-pathogen dynamics.
- Environmental and ecological factors significantly impact mosquito community structure and pathogen circulation.
- Findings support evidence-based vector control strategies and public health decision-making.

Investigation of Disease Outbreaks
Multistate foodborne outbreaks pose significant public health risks and require meticulous investigation to identify sources and implement control measures. The Centers for Disease Control and Prevention (CDC) utilizes a dynamic seven-step process for these investigations, integrating data from laboratories, interviews, and environmental assessments to protect public health.Outbreak Detection: The detection of multistate outbreaks typically begins with PulseNet, the CDC's national laboratory...
Toxoplasmosis
Toxoplasmosis, a zoonotic disease caused by the protozoan Toxoplasma gondii, poses significant public health challenges globally due to its high seroprevalence and varied clinical manifestations. As an obligate intracellular parasite, T. gondii can infect all warm-blooded vertebrates, but felids are its only definitive hosts, shedding unsporulated oocysts into the environment. Humans typically acquire the infection through ingestion of tissue cysts in undercooked meat or oocysts from...
Arboviral Encephalitis
Arboviral encephalitis refers to brain inflammation caused by arthropod-borne viruses, particularly those transmitted through mosquito vectors. Among these, West Nile virus (WNV), a member of the Flaviviridae family, is a significant public health concern. WNV is an enveloped, positive-sense, single-stranded RNA virus. Human infection typically begins when an infected mosquito introduces the virus into the dermis during feeding. The primary transmission cycle involves birds as amplifying hosts...
