Grupo de Parasitología, Instituto Nacional de Salud de Colombia, Bogotá, Colombia.
Article Synopsis
- A 40-year-old male from Vereda Buenos Aires presented to the emergency department with symptoms including fever, headache, and dysuria, initially diagnosed with a urinary tract infection.
- After five days, he was confirmed to have acute phase Chagas disease due to a positive result for Trypanosoma cruzi.
- The patient received treatment with nifurtimox and benznidazole, and health authorities conducted investigations in the community, identifying five other symptomatic individuals, but further tests for Chagas were negative, leading to health education initiatives to prevent disease spread.
Entomological indicators and food sources of triatomines in the Brazilian semi-arid region.

Universidade Federal Rural de Pernambuco, Programa de Pós-graduação em Biociência Animal, Recife, PE, Brasil.
Background: Triatomines are biological vectors of Trypanosoma cruzi, the etiological agent of Chagas Disease (CD) and have various mammalian hosts. This study evaluated the entomological indicators and food sources of triatomines in Petrolina in the semi-arid region of Brazil, where CD is endemic.
Methods: Triatomines were captured indoors and outdoors through an active search and entomological indices (household and natural infections) were calculated.
Rapid assessment of the blood-feeding histories of wild-caught malaria mosquitoes using mid-infrared spectroscopy and machine learning.

School of Biodiversity, One Health and Veterinary Medicine, University of Glasgow, Glasgow, G12 8QQ, UK.
Article Synopsis
- Researchers studied how much Anopheles mosquitoes prefer biting humans to predict malaria risk.
- They used a new method called mid-infrared spectroscopy and machine learning to quickly check the blood meals of these mosquitoes collected in Tanzania.
- The new technique was found to be accurate and could help monitor malaria more easily and cheaply compared to traditional methods.
Epidemiological study on cattle trypanosomiasis and its vectors distributions in the Gambella regional state, southwestern Ethiopia.

School of Veterinary Medicine, Wolaita Sodo University, Wolaita Sodo, Ethiopia. Electronic address:
African animal trypanosomosis is a parasitic disease that causes significant economic losses in livestock due to anaemia, loss of condition, emaciation, and mortality. It is a key impediment to increased cattle output and productivity in Ethiopia. Cross-sectional entomological and parasitological studies were performed in the Gambella Region state of southwestern Ethiopia to estimate the prevalence of bovine trypanosomosis, apparent fly density, and potential risk factors.

African animal trypanosomosis (AAT) was one of the main disease-related constraints to the development of intensive livestock production systems in the Niayes region of Senegal, a 30 km wide strip of land along the coast between Dakar and Saint-Louis. To overcome this constraint, the Government of Senegal initiated an area-wide integrated pest management programme combining chemical control tactics with the sterile insect technique to eradicate a population of the tsetse fly Glossina palpalis gambiensis Vanderplank, 1949 (Diptera, Glossinidae) in this area. The project was implemented following a phased conditional approach, and the target area was divided into three blocks treated sequentially.
