Anhydroparthenin as a dual-target inhibitor against Sterol C-24 methyltransferase and Sterol 14- α demethylase of Leishmania donovani: A comprehensive in vitro and in silico study
Int J Biol Macromol. 2024 May 1:132034. doi: 10.1016/j.ijbiomac.2024.132034. Online ahead of print.ABSTRACTParthenium hysterophorus plant has a diverse chemical profile and immense bioactive potential. It exhibits excellent pharmacological properties such as anti-cancer, anti-inflammatory, anti-malarial, microbicidal, and anti-trypanosomal. The present study aims to evaluate the anti-leishmanial potential and toxicological safety of anhydroparthenin isolated from P. hysterophorus. Anydroparthenin was extracted from the leaves of P. hysterophorus and characterized through detailed analysis of 1H, 13C NMR, and HRMS. Dye-base...

Redescription of adults and first description of the larva of Haemaphysalis (Rhipistoma) adleri Feldman-Muhsam, 1951 (Acari: Ixodidae), parasite of carnivorans in Western Asia
Syst Parasitol. 2024 May 3;101(3):36. doi: 10.1007/s11230-024-10156-1.ABSTRACTThe adults of Haemaphysalis (Rhipistoma) adleri Feldman-Muhsam, 1951 (Acari: Ixodidae) are redescribed and the larva of this species is described for the first time here. The adults of H. adleri that we studied were collected from various canid, felid and hyaenid carnivorans (Carnivora: Canidae, Felidae, Hyaenidae) as well as a hedgehog (Erinaceomorpha: Erinaceidae) in Iraq, Israel and West Bank. The males, females and larvae of H. adleri can be differentiated from Haemaphysalis (Rhipistoma) species occurring in the Palearctic portion of West Asi...

Nomenclatural stability and the longevity of helminth species names
Syst Parasitol. 2024 May 3;101(3):34. doi: 10.1007/s11230-024-10161-4.ABSTRACTAlthough most Latin binomial names of species are valid, many are eventually unaccepted when they are found to be synonyms of previously described species, or superseded by a new combination when the species they denote are moved to a different genus. What proportion of parasite species names become unaccepted over time, and how long does it take for incorrect names to become unaccepted? Here, we address these questions using a dataset comprising thousands of species names of parasitic helminths from four higher taxa (Acanthocephala, Nematoda, Ce...

Not that many leech species after all: Myzobdella lugubris and Myzobdella patzcuarensis (Annelida: Hirudinida) are the same species
Syst Parasitol. 2024 May 3;101(3):38. doi: 10.1007/s11230-024-10160-5.ABSTRACTThe genus Myzobdella groups five species of leeches parasites of fishes mainly of freshwater but with tolerance to brackish waters. Native distribution of these species includes the New World from North to South America. Myzobdella lugubris Leidy, 1851, the type species of the genus, was briefly described based on specimens from the USA, but subsequently their morphology, known distribution and host range were expanded; however, less is known about the other four species of the genus. As part of a survey focusing on characterizing the diversity o...

GSE266399 Cytoadhesion of Plasmodium falciparum-infected red blood cells changes the expression of cytokine-, histone- and antiviral protein-encoding genes in brain endothelial cells
Conclusion The presence of iRBCs leads to the stimulation of ECs, activating several immunological signaling pathways and affecting antiviral (-parasitic) mechanism s and angiogenesis. Furthermore, to our knowledge, the induction of the interferon-alpha/beta signaling pathway in ECs in response to iRBCs has been described for the first time. (Source: GEO: Gene Expression Omnibus)

Year-round monitoring of three water sources in Qu ébec, Canada, reveals site-specific differences in conditions for Cryptosporidium and Giardia contamination
Canadian Journal of Microbiology, Ahead of Print. Cryptosporidium and Giardia are protozoan parasites responsible for gastrointestinal illnesses in humans and in animal species. The main way these parasites are transmitted is by ingestion of their (oo)cysts in drinking water. Monitoring (oo)cysts in water sources is beneficial to evaluate the quality of raw water supplying treatment plants. Currently, the only standardized protocol to enumerate these parasites from water samples is United States Environmental Protection Agency (USEPA) Method 1623.1. With this method, we monitored three major water sources in Quebec over a ...

Transcriptome profiles of < i > Trypanosoma brucei rhodesiense < /i > in Malawi reveal focus specific gene expression profiles associated with pathology
ConclusionOur results suggest that the differences in disease presentation in the two foci is mainly driven by genetic differences in the parasites in the two major endemic foci of Rumphi and Nkhotakota rather than differences in the environment or host response.

Mitochondrial genome fragmentation is correlated with increased rates of molecular evolution
by Tom áš Najer, Jorge Doña, Aleš Buček, Andrew D. Sweet, Oldřich Sychra, Kevin P. Johnson While mitochondrial genome content and organization is quite diverse across all Eukaryotes, most bilaterian animal mitochondrial genomes (mitogenomes) exhibit highly conserved gene content and organisation, with genes typically encoded on a single circular chromosome. However, many species of parasitic lice (Insecta: Phthiraptera) are among the notable exceptions, having mitogenomes fragmented into multiple circular chromosomes. To better understand the process of mitogenome fragmentation, we conducted a large-scale genomic st...

The Transmission of Animal African Trypanosomiasis in Two Districts in the Forest Zone of Ghana
Am J Trop Med Hyg. 2024 May 2:tpmd230329. doi: 10.4269/ajtmh.23-0329. Online ahead of print.ABSTRACTAnimal African trypanosomiasis, also known as nagana, is caused by Trypanosoma species, which cause significant clinical diseases and lead to losses in animal production. We carried out a cross-sectional survey to investigate the composition of vectors and parasite diversity in two districts in the eastern region of Ghana where pigs and cattle were exposed to tsetse bites. We performed cytochrome c oxidase subunit 1 polymerase chain reaction (PCR) to identify tsetse species and internal transcribed spacer 1 PCR to identify T...
