Single and mixture exposure to atrazine and ciprofloxacin on Clarias gariepinus antioxidant defense status, hepatic condition and immune response.

Atrazine (ATRA) and ciprofloxacin (CPRO) are widely detected, persistent and co-existing aquatic pollutants. This study investigated effects of 14-day single and joint ATRA and CPRO exposure on juvenile Clarias gariepinus. Standard bioassay methods were used to determine responses of oxidative stress, hepatic condition, and immunological biomarkers on days 7 and 14.

Distribution and ecological risk assessment of herbicide residues in water, sediment and fish from Anyim River, Ebonyi State, Nigeria.

The presence of herbicide residues in water, sediment and African catfish (Clarias gariepinus) from Anyim River was investigated bimonthly from November, 2017 to September 2019. The aim of the study was to evaluate the pollution status of the river and the associated health hazard. The herbicides investigated were glyphosate-based and included sarosate, paraquat, clear weed, delsate and roundup.

studies on the biochemical indices of infected mice treated with leaf and root extracts.

Background: A study on the biochemical indices of albino mice infected with and treated with aqueous and ethanolic extracts was undertaken.

Methods: 216 males mice were randomly assigned to six treatment groups each containing six mice for both aqueous and ethanolic extracts experiments. NK-65 was inoculated into the mice intraperitoneally and establishment of infection confirmed.

Status of Onchocerca volvulus infection and transmission by blackflies after 15 years of ivermectin distribution at Adani, Nigeria.

The nuisance bites of blackflies and transmission of Onchocerca volvulus, which causes onchocerciasis, constitutes a threat to public health and an impediment to food production in rural and riverine communities in Nigeria. The entomological profile of onchocerciasis at Adani, Nigeria, was investigated from August 2010 to January 2011 to determine the transmission of O. volvulus after 15 years of ivermectin distribution in the area.

Maternal vitamin A supplementation delays time to first episode of parasitaemia and reduces malaria parasite densities among infants in rural communities in Ebonyi State, Nigeria.

The study was a randomized mother -infant dyad placebo controlled field trial that evaluated the effect of maternal vitamin A supplementation on time to first episode of parasitaemia and on malaria parasite densities among infants in three rural communities in Ebonyi State, Nigeria. One hundred and fifty-two (152) pregnant women with pregnancies that had mature to at least six (6) months were equally randomized into supplemented and placebo groups. Ten thousand international unit (10,000 IU) of vitamin A supplement was administered three (3) times per week to women of the supplemented group while placebo was given to the control group at equal frequencies.
