Phytochemical profiling and anthelmintic potential of extracts of selected tropical plants on parasites of fishes in Epe Lagoon.

This research aims to study the anthelmintic properties of selected five (5) tropical plant extracts, ascertained margin of fish host safety in reference with praziquantel, a commonly used chemo-therapeutics. Qualitative and quantitative analysis of Alligator pepper seeds (Aframomum melegueta), Moringa leaves (Moringa oleifera), Neem leaves (Azadirachta indica), Ginger bulbs (Zingiber officinale) and Garlic (Allium sativum) and their potencies in reference to praziquantel against Clarias gariepinus and different classes of helminth parasites were investigated. The results obtained show that the 70% ethanol extract had 80 to 100% presence of the phytochemical content, compared with the 100% aqueous and 100% ethanol extracts with 50 to 80% and 50 to 90%, respectively.

Exploring the genetic diversity of Eimeria acervulina: A polymerase chain Reaction-Restriction Fragment Length Polymorphism (PCR-RFLP) approach.

Eimeria, protozoan parasites that can cause the disease coccidiosis, pose a persistent challenge to poultry production and welfare. Control is commonly achieved using good husbandry supplemented with routine chemoprophylaxis and/or live parasite vaccination, although widespread drug resistance and challenges to vaccine supply or cost can prove limiting. Extensive effort has been applied to develop subunit anticoccidial vaccines as scalable, cost-effective alternatives, but translation to the field will require a robust understanding of parasite diversity.

Bioaccumulation of organochlorine pesticides in the parasite sp. (Nematoda: Cosmocercidae) and the amphibian host (Reuss, 1833) within Lagos metropolis, Nigeria.

Background: Amphibian species are being threatened worldwide and chemical pollution is one of the leading causes of this decline. The use of agrochemicals such as organochlorine pesticides (OCPs) among the several health and ecological challenges it causes, the sharp amphibian population decline is most pressing.Toad specimens were sampled from three (3) selected areas; each comprising of natural habitat and dumpsites within Lagos metropolis.

Studies on heavy metals and fish health indicators in from Lekki Lagoon, Lagos, Nigeria.

The aquatic ecosystem is constantly being disturbed by rising levels of different classes of pollutants of human origin in the form of urban, agricultural and industrial discharges. In this study, the health of fish was examined, to serve as a reflection of the impact of anthropogenic disturbances in the Lekki lagoon. Eighty six samples of the fish were analysed for parasitic infections, heavy metals, microorganisms in their internal and external body parts while the proximate composition and fish condition factor were also determined using conventional methods.

Bioaccumulation of Organochlorine Pesticides, Procamallanus sp. (Baylis, 1923) infections, and Microbial Colonization in African Snakehead fish Sampled from Lekki Lagoon, Lagos, Nigeria.

The exponential rise in the Nigerian population has necessitated the use of agrochemicals for enhanced agricultural yields to meet the ever-rising demand for food. However, agrochemicals such as organochlorine pesticides (OCPs) have caused several devastating health and ecological challenges. The study was therefore aimed at assessing the bioaccumulation of OCPs and the associated parasitological and microbial susceptibility in P.
