An Outbreak of Acute Chagas Disease Possibly Spread through Oral Transmission Involving Animal Reservoirs in Eastern Colombia
Am J Trop Med Hyg. 2023 Nov 13:tpmd230380. doi: 10.4269/ajtmh.23-0380. Online ahead of print.ABSTRACTChagas disease (CD) is a parasitic infection caused by the parasite Trypanosoma cruzi. Reports of CD cases associated with oral transmission have increased, particularly in Colombia, Brazil, and Venezuela. In this investigation, parasitological, serological, and molecular tests were conducted on samples obtained from humans, mammal reservoirs, and hosts involved in the assessment of a suspected oral transmission outbreak in Cubara, Boyaca, Colombia. Seropositivity was observed in 60% (3 of 5) of index patients and 6.4% (5 o...

Sociodemographic, migratory and health-related determinants of food insecurity among Venezuelan migrants in Peru Food insecurity among Venezuelan migrants in Peru
CONCLUSION: Four out of 10 Venezuelan migrants residing in Peru presented moderate to severe FI. The FIES showed adequate psychometric properties. Differences in the sociodemographic, health, and migratory factors associated with FI levels were found. Inter-sectoral and multi-sectoral interventions are needed and should be focused on addressing the determinants of FI.PMID:37944992 | DOI:10.1017/S1368980023002513 (Source: Public Health Nutrition)

Genetic diversity and natural selection of apical membrane antigen-1 (ama-1) in Cameroonian Plasmodium falciparum isolates
Gene. 2023 Nov 2:147956. doi: 10.1016/j.gene.2023.147956. Online ahead of print.ABSTRACTAntigenic variation associated with genetic diversity in global Plasmodium falciparum apical membrane antigen-1 (PfAMA-1) is a major impediment to designing an effective malaria vaccine. Here, we report the first study on genetic diversity and natural selection of the Pfama-1 gene in P. falciparum isolates from Cameroon. A total of 328 P. falciparum positive samples collected during 2016 and 2019 from five localities of Cameroon were analysed. The ectodomain coding fragment of Pfama-1 gene was amplified for polymorphism profiling and na...

Detection and diversity of gastrointestinal viruses in wastewater from Caracas, Venezuela, 2021-2022
Virology. 2023 Oct 23;589:109913. doi: 10.1016/j.virol.2023.109913. Online ahead of print.ABSTRACTGastrointestinal viruses (GIV) are an important cause of childhood morbidity and mortality, particularly in developing countries. Their epidemiological impact in Venezuela during the COVID-19 pandemic remains unclear. GIV can also be detected in domestic sewage. Ninety-one wastewater samples from urban areas of Caracas collected over 12 months and concentrated by polyethylene-glycol-precipitation, were analyzed by multiplex reverse-transcription-PCR for rotavirus/calicivirus/astrovirus and enterovirus/klassevirus/cosavirus, an...
