Summary
Tick-borne diseases are prevalent in Sicily, affecting dogs with babesiosis and ehrlichiosis. Studies confirm widespread presence of zoonotic agents like Rickettsia conorii and Coxiella burnetii in canine populations across the region.
Area of Science:
- Veterinary Medicine
- Epidemiology
- Zoonotic Diseases
Background:
- Tick-borne diseases are endemic in Sicily, favored by warm, humid climates.
- Babesiosis and ehrlichiosis are significant tick-transmitted canine diseases.
- Several tick-borne pathogens are zoonotic, posing risks to public health.
Purpose of the Study:
- To estimate the prevalence of major tick-borne diseases in Sicilian dogs.
- To assess the seroprevalence of specific tick-borne zoonotic agents in dogs.
- To confirm the presence of tick-borne pathogens across all Sicilian territories.
Main Methods:
- A study involving 342 dogs to determine seroprevalence for Babesia canis, Ehrlichia canis, and Rickettsia spp.
- Analysis of zoonotic agent seroprevalences including Coxiella burnetii, Rickettsia conorii, and Anaplasma phagocytophilum.
- Examination of diagnostic data from 5,634 tests conducted by IZS Sicily between 2004-2005.
Main Results:
- Seroprevalence rates in the initial study: Babesia canis (5.17%), Ehrlichia canis (21.70%), Rickettsia spp. (53.43%).
- Zoonotic agent seroprevalences: Coxiella burnetii (31.50%), Rickettsia conorii (73.60%), Anaplasma phagocytophilum (32.80%).
- IZS Sicily data confirmed the presence of multiple tick-borne pathogens (B. canis, E. canis, R. conorii, A. phagocytophilum, C. burnetii, Rickettsia spp., Anaplasma spp., Ehrlichia spp.) throughout Sicily.
Conclusions:
- Tick-borne diseases and zoonotic agents are widespread among dogs in Sicily.
- Canine surveillance is crucial for monitoring and controlling tick-borne diseases and zoonotic risks.
- The findings highlight the public health importance of tick-borne pathogens in the region.

Rocky Mountain Spotted Fever
Rocky Mountain Spotted Fever (RMSF) is a severe tick-borne illness caused by Rickettsia rickettsii, a Gram-negative, coccobacillary bacterium. This pathogen is an obligate intracellular parasite, requiring a host cell for replication. Transmission occurs through the bite of an infected tick. In the United States, the most important vectors are Dermacentor variabilis (American dog tick) and Dermacentor andersoni (Rocky Mountain wood tick), though other tick species may also serve as vectors.
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...
Rabies
Rabies is a lethal zoonotic disease caused by a single-stranded, negative-sense RNA virus of the Lyssavirus genus, within the family Rhabdoviridae. Its primary mode of transmission to humans is through bites or saliva-contaminated scratches from infected mammals such as dogs, bats, raccoons, or foxes. Transmission can also occur if infectious saliva contacts abraded skin or intact mucous membranes, including the conjunctiva.Viral Entry and Early ReplicationOnce introduced at the bite or scratch...
American Trypanosomiasis
Chagas disease, or American trypanosomiasis, is a vector-borne parasitic infection caused by Trypanosoma cruzi, a flagellated protozoan (kinetoplastid) of the family Trypanosomatidae. The disease is endemic in Latin America, although cases are increasingly reported worldwide due to human migration. Transmission most commonly occurs when feces of infected triatomine bugs contaminate bite wounds or mucosal surfaces; additional routes include congenital, transfusional, transplant-related, and oral...
Giardiasis
Giardiasis is a globally prevalent intestinal infection caused by the protozoan parasite Giardia duodenalis (also known as G. lamblia or G. intestinalis). This flagellated protozoan is the most frequently identified intestinal parasite in the United States and worldwide. Transmission primarily occurs via the fecal-oral route, with infection arising from ingestion of water or food contaminated with cysts. Individuals in low-resource settings, international travelers, outdoor enthusiasts, daycare...
Leishmaniasis
Leishmaniasis is a protozoal disease caused by species of the genus Leishmania and transmitted through the bite of infected female sandflies. The parasite exists in two principal morphological forms during its life cycle. A sandfly acquires intracellular amastigotes from an infected reservoir host, such as a dog. Within the sandfly, these forms differentiate into motile, flagellated promastigotes. During a subsequent blood meal, promastigotes are injected into the human host, where they...
