In its native and invasive range, the longhorned tick is known to transmit a wide variety of pathogens. Researchers have found evidence of infection in field-collected specimens in the U.S. with pathogens that cause Lyme disease, anaplasmosis, babesiosis, Bourbon virus disease, and theileriosis; however, it is still unknown if the tick can spread many of these disease agents.
Cyclospora cayetanensis is a coccidian protozoan
CDC says: Cyclosporiasis illnesses are reported year-round in the United States. However, during the spring and summer months there is often an increase in cyclosporiasis acquired in the United States.
Dracunculiasis (Guinea worm disease), caused by the parasite Dracunculus medinensis, is acquired by drinking water containing small water fleas infected with D. medinensis larvae or eating inadequately cooked aquatic animals.

The PCR assay developed here differentiates Leishmania infantum and Crithidia sp. LVH60A parasites with the ability to detect and estimate parasite load in samples from different hosts involved in infection (human, animal, and experimental) and can be used for epidemiological studies, parasite load monitoring, and therapeutic follow-up. Samples analysed in this study included human bone marrow and peripheral blood, as well as for the spleen and liver samples of dogs and hamsters
Plasmodium spp is an apicomplexa parasite
Advisors to the WHO recently recommended a second malaria vaccine.
CDC says: locally acquired mosquito-transmitted malaria cases can occur, as Anopheles mosquito vectors exist throughout the United States. In 2003 there were 8 cases of locally acquired P. vivax malaria identified in Palm Beach County, FL.
Courtney AP, Boyanton BL Jr., Strebeck PV, et al.
After 20 years without locally acquired mosquito-transmitted malaria in the United States, nine cases were reported to CDC during May–August 2023.
This report summarizes the epidemiology of and risks for infection with TBE virus, provides information on the immunogenicity and safety of TBE vaccine, and summarizes the recommendations of the ACIP for use of TBE vaccine among U.S. travelers and laboratory workers.
A group in Brazil screend 160 compounds belonging to the COVID Box, a library of compounds developed by Medicines for Malaria Venture (MMV) to combat SARS-CoV-2.
Chagas disease, or American trypanosomiasis, is caused by the parasitic protozoan Trypanosoma cruzi, which is transmitted through congenital, oral, and vectorborne routes; vectorborne infections result from contact with the feces of infected triatomine insects (kissing bugs).

Here, we argue why this parasitic infection should be included in the new estimates of the health burden of foodborne diseases. Growing evidence indicates that foodborne transmission of T. cruzi occurs as commonly as vector-borne infection. Moreover, foodborne infection results in considerably more severe disease than vector-borne infection, with higher mortality and greater symptom severity, particular in the acute phase.
