The unusual kinetics of lactate dehydrogenase of Schistosoma mansoni and their role in the rapid metabolic switch after penetration of the mammalian host
Int J Parasitol. 2024 Mar 14:S0020-7519(24)00054-7. doi: 10.1016/j.ijpara.2024.03.005. Online ahead of print.ABSTRACTLactate dehydrogenase (LDH) from Schistosoma mansoni has peculiar properties for a eukaryotic LDH. Schistosomal LDH (SmLDH) isolated from schistosomes, and the recombinantly expressed protein, are strongly inhibited by ATP, which is neutralized by fructose-1,6-bisphosphate (FBP). In the conserved FBP/anion binding site we identified two residues in SmLDH (Val187 and Tyr190) that differ from the conserved residues in LDHs of other eukaryotes, but are identical to conserved residues in FBP-sensitive prokaryoti...

Comparative genomics analysis reveals sequence characteristics potentially related to host preference in Cryptosporidium xiaoi
In this study, we sequenced the genomes of two C. xiaoi isolates and performed comparative genomic analysis to identify the sequence uniqueness of this ovine-adapted species compared with other Cryptosporidium spp. Our results showed that C. xiaoi is genetically related to C. bovis as shown by their 95.8% genomic identity and similar gene content. Consistent with this, both C. xiaoi and C. bovis appear to have fewer genes encoding mitochondrial metabolic enzymes and invasion-related protein families. However, they appear to possess several species-specific genes. Further analysis indicates that the sequence differences bet...

Sympatry in a nightingale contact zone has no effect on host-specific blood parasite prevalence and lineage diversity
Int J Parasitol. 2024 Mar 7:S0020-7519(24)00052-3. doi: 10.1016/j.ijpara.2024.03.002. Online ahead of print.ABSTRACTParasites are a key driving force behind many ecological and evolutionary processes. Prevalence and diversity of parasites, as well as their effects on hosts, are not uniform across host species. As such, the potential parasite spillover between species can significantly influence outcomes of interspecific interactions. We screened two species of Luscinia nightingales for haemosporidian blood parasites (Plasmodium, Leucocytozoon and Haemoproteus) along an approximately 3,000 km transect in Europe, incorporati...

Assessing the role of individual foxes in environmental contamination with Echinococcus multilocularis through faecal samples
Int J Parasitol. 2024 Mar 7:S0020-7519(24)00053-5. doi: 10.1016/j.ijpara.2024.03.003. Online ahead of print.ABSTRACTKey parasite transmission parameters are difficult to obtain from elusive wild animals. For Echinococcus multilocularis, the causative agent of alveolar echinococcosis (AE), the red fox is responsible for most of the environmental contamination in Europe. The identification of individual spreaders of E. multilocularis environmental contamination is crucial to improving our understanding of the ecology of parasite transmission in areas of high endemicity and optimising the effectiveness of prevention and contr...
