On the occurrence of parasite, Lernaea cyprinacea from common carp, Cyprinus carpio farmed in ponds and rice fields

Abstract Lernaea cyprinacea and occurrence of Lernaeasis in farmed and wild warm water fishes is a major problem of aquaculture industry in Iran. The present study was conducted to compare the rate of L. cyprinacea infection between two separate populations of common carp, i.e., fish cultured in ponds and sampled from rice fields. To this end, fish sampling was done during 3 months in summer. After fish sampling, fish were transferred to lab for parasite study. Parasite incidence percent and density were calculated for two population carps. According to obtained results, the parasite incidence percent and density were significantly higher in fish samples taken from fish ponds than in those from rice fields (P

In this study, we genetically characterised Monogenea found on the gill of common carp in Iran. In total, 5603 parasites were recovered from 112 fish. The parasites were first identified morphologically as Dactylogyrus extensus, D. anchoratus, D. vastator, D. minutus, D. achmerowi and Gyrodactylus sprostonae. Representative samples were then subjected to sequencing. This is one of the first studies which has provided both morphological and sequence data for Dactylogyrus spp. and G. sprostonae. Our findings provide a foundation for future research into the genetic make-up of these economically significant parasites and the ...

Publication date: Available online 21 August 2019Source: Ticks and Tick-borne DiseasesAuthor(s): R. Megía-Palma, D. Paranjpe, P. Blaimont, R. Cooper, B. SinervoAbstractIt is generally accepted that parasites exert negative effects on their hosts and that natural selection favors specific host responses that mitigate this impact. It is also known that some components of the host immune system often co-evolve with parasite antigens resulting in a host-parasite arms race. In addition to immunological components of the anti-parasitic response, host behavioral responses are also important in this arms race and natural se...

Three-year review says new vaccines for eradicating disease are only 40% effectiveMalaria will not be eradicated in the foreseeable future even though it is achievable and would save millions of lives, according to World Health Organization (WHO) experts following a three-year review.The WHO remains committed to the “disappearance of every single malaria parasite from the face of the planet”, as it has been since the UN organisation was launched in 1948, said Dr Pedro Alonso, the director of its global malaria programme.Continue reading...

The chloroquine resistance transporter PfCRT of the human malaria parasite Plasmodium falciparum confers resistance to the former first-line antimalarial drug chloroquine, and it modulates the responsiveness to a wide range of quinoline and quinoline-like compounds. PfCRT is post-translationally modified by phosphorylation, palmitoylation, and, possibly, ubiquitination. However, the impact of these post-translational modifications on P. falciparum biology and, in particular, the drug resistance–conferring activity of PfCRT has remained elusive. Here, we confirm phosphorylation at Ser-33 and Ser-411 of PfCRT of the ch...

J-DNA–binding protein 1 (JBP1) contributes to the biosynthesis and maintenance of base J (β-d-glucosyl-hydroxymethyluracil), an epigenetic modification of thymidine (T) confined to pathogenic protozoa such as Trypanosoma and Leishmania. JBP1 has two known functional domains: an N-terminal T hydroxylase (TH) homologous to the 5-methylcytosine hydroxylase domain in TET proteins and a J-DNA–binding domain (JDBD) that resides in the middle of JBP1. Here, we show that removing JDBD from JBP1 results in a soluble protein (Δ-JDBD) with the N- and C-terminal regions tightly associated together in a well-orde...

Trypanosoma cruzi, the causative agent of Chagas disease, exhibits a high genetic variability and has been classified into six discrete typing units (DTUs) named TcI-TcVI. This genetic diversity is believed to be associated with clinical characteristics and outcomes, but evidences supporting such associations have been limited. Here we performed a phylogenetic analysis of T. cruzi sequences of the mini-exon intergenic region obtained from a large cohort of pregnant women and newborns from Argentina, Honduras, and Mexico, to assess parasite genetic diversity and possible associations with congenital transmission.

To gain insights into differences in the virulence among T. gondii strains at the posttranslational level, we conducted a quantitative analysis of the phosphoproteome profile of T. gondii strains belonging to three different genotypes. Phosphopeptides from the three strains type I (RH strain), type II (PRU strain), and PYS strain (Chinese ToxoDB#9) were enriched by titanium dioxide (TiO2) affinity chromatography and quantified using iTRAQ technology. A total of 1,441 phosphopeptides, 1,250 phosphorylation sites and 759 phosphoproteins were detected. In addition, 392, 298 and 436 differentially expressed phosphoproteins (DE...
