Genomics of Plasmodium vivax in Colombia reveals evidence of local bottle-necking and inter-country connectivity in the Americas.

Colombia aims to eliminate malaria by 2030 but remains one of the highest burden countries in the Americas. Plasmodium vivax contributes half of all malaria cases, with its control challenged by relapsing parasitaemia, drug resistance and cross-border spread. Using 64 Colombian P.

The single nucleotide polymorphisms SNPs associated with multiple therapy resistance in Colombia.

The eradication of () using multiple therapies is used as a prevention strategy. However, its efficacy has been compromised by the emergence of single nucleotide polymorphisms in genes associated with resistance to multiple antibiotics. To estimate antibiotic resistance rates associated with mutations in genes in the high-cancer-risk population in Colombia, we included 166 whole genome sequences from a cohort of individuals with a high risk of gastric cancer.

A molecular barcode and web-based data analysis tool to identify imported Plasmodium vivax malaria.

Traditionally, patient travel history has been used to distinguish imported from autochthonous malaria cases, but the dormant liver stages of Plasmodium vivax confound this approach. Molecular tools offer an alternative method to identify, and map imported cases. Using machine learning approaches incorporating hierarchical fixation index and decision tree analyses applied to 799 P.

State of Artemisinin and Partner Drug Susceptibility in Clinical Isolates from Colombia.

Delayed parasite clearance time observed in Southeast Asia provided the first evidence of resistance to artemisinins. The ex vivo ring-stage survival assay (RSA) mimics parasite exposure to pharmacologically relevant artemisinin concentrations. Mutations in the C-terminal propeller domain of the putative kelch protein Pf3D7_1343700 (K13) are associated with artemisinin resistance.

Telmisartan-induced sprue-like enteropathy: a case report.

A possible case of sprue-like enteropathy (SLE) induced by the use of telmisartan is reported. Telmisartan is an angiotensin-receptor II blocker (type 1) used for the treatment of hypertension. Several cases of SLE associated with olmesartan and other drugs of the same group have been reported.

Evidence of Self-Medication with Chloroquine before Consultation for Malaria in the Southern Pacific Coast Region of Colombia.

Self-medication with antimalarial drugs is a major factor in the development of drug resistance, exerting subtherapeutic drug pressure on circulating parasite populations. Data on self-medication with antimalarials from the Southern Pacific coast region of Colombia, where 4-aminoquinolines resistance and political instability prevail, are vital to elimination strategies. We present results of an exploratory study of 254 individuals having malaria symptoms who sought malaria diagnosis in two hospitals in Tumaco, Department of Nariño, Colombia.

Genetic Characterisation of Plasmodium falciparum Isolates with Deletion of the pfhrp2 and/or pfhrp3 Genes in Colombia: The Amazon Region, a Challenge for Malaria Diagnosis and Control.

Most Plasmodium falciparum-detecting rapid diagnostic tests (RDTs) target histidine-rich protein 2 (PfHRP2). However, P. falciparum isolates with deletion of the pfhrp2 gene and its homolog gene, pfhrp3, have been detected.
