In Vitro and In Vivo Antitrypanosomal Activities of Methanol Extract of Echinops kebericho Roots.

In Vitro and In Vivo Antitrypanosomal Activities of Methanol Extract of Echinops kebericho Roots. Evid Based Complement Alternat Med. 2020;2020:8146756 Authors: Abdeta D, Kebede N, Giday M, Terefe G, Abay SM Abstract Microbial resistance to the few conventional antitrypanosomal drugs, increasing resistance of vectors to insecticides, lack of effective vaccines, and adverse effects of the existing antitrypanosomal drugs justify the urgent need for effective, tolerable, and affordable drugs. We assessed antitrypanosomal effects of the hydromethanolic extract of Echinops kebericho Mesfin roots against Trypanosoma congolense field isolate using in vitro and in vivo techniques. Parasite load, packed cell volume (PCV), body weight, and rectal temperature in Swiss albino mice were assessed. This finding is part of the outcomes of drug discovery research for neglected tropical diseases. The extract arrested the motility of trypanosomes within 40 min at 4 and 2 mg/mL concentration, whereas in the untreated control, motility continued for more than 160 min. The extract also reduced parasitemia and prevented drop in PCV and body weight significantly (p

Conclusion: This study demonstrates that the crude extract of A. hispidum DC, one of the plants used traditionally to treat malaria, inhibits the growth of P. falciparum in vitro and could be a potential source of antimalarial drug. The report has highlighted genotoxic and cytotoxic effects of the selected plant extracts on human leukocytes as well. PMID: 33029160 [PubMed]

(Nagoya University) Using the model Orobanchaceae parasitic plant Phtheirospermum japonicum, scientists have discerned the molecular mechanisms underlying plant parasitism and cross-species grafting, pinpointing enzymeβ-1,4-glucanase (GH9B3) as an important contributor to both phenomena. Targeting this enzyme may help control plant parasitism in crops.

Conclusions: The low prevalence of asymptomatic malaria parasite carriage by the children living in the Cape Coast Metropolis suggests that the malaria control interventions in place in CCMA are highly effective and that additional malaria control interventions are required for the KEEA district to reduce the prevalence of asymptomatic malaria parasite carriers. No molecular evidence of P. ovale and P. vivax was identified in the afebrile children sampled from the selected schools. PMID: 33029151 [PubMed]

Study seeks to compare microbiomes of our ancestors for clues to modern diseasesResearchers working knee-deep in 14th- and 15th-century latrines have found that bacterial DNA from human excrement can last for centuries and provide clues to how our gut contents have changed significantly since medieval times.Analysis of two cesspits, one in Jerusalem and the other in the Latvian capital, Riga, could help scientists understand if changes to our microbiome – the genetic makeup of the bacteria, virus, fungi, parasites and other microbes living inside us – affect modern-day afflictions.Continue reading...

(New York University) A team of researchers at NYU Abu Dhabi (NYUAD) has found that the Plasmodium parasite, which transmits malaria to humans through infected mosquitos, triggers changes in human genes that alter the body's adaptive immune response to malarial infections.

Holmes Genetic surveillance of malaria parasites supports malaria control programmes, treatment guidelines and elimination strategies. Surveillance studies often pose questions about malaria parasite ancestry (e.g. how antimalarial resistance has spread) and employ statistical methods that characterise p arasite population structure. Many of the methods used to characterise structure are unsupervised machine learning algorithms which depend on a genetic distance matrix, notably principal coordinates ana...
