The study evaluated nutritional and organoleptic properties of Clarias gariepinus pre-treated with aqueous leave extracts of Ocimum gratissimum and Vernonia amygdalina before processing. Thirty-six (36) C. gariepinus (live weight = 1.2± 0.2kg) samples were procured and processed for the study. Fish samples were divided into three parts of twelve fish each. Each part was grouped into three treatments having four fish in each group using a completely randomized design. Treatment one (T1) had fish immersed in 5% brine without herbal extract (control). In Treatment two (T2), fish were soaked in mixture of 5% brine and 5% O. gratissium (scent leaf) extracts while Treatment three (T3) had fish soaked in mixture of 5% brine and 5% V. amygdalina (bitter leaf) extracts all for 30 minutes. Treated fish samples were smoke-dried using charcoal kiln for 5 hours at temperature of 80 – 90° C. Samples were then cooled under ambient condition (30+3oC) for 4 hours. The smoke-dried fish samples were labeled according to treatments and stored for 7 days under aseptic condition. Organoleptic properties of the samples were conducted at every 24-hour of storage using a 9-point hedonic scale. Mean values of proximate composition of samples were significantly different (p<0.05). Protein content (70.01%) in T3 was higher than 68.31% and 66.62% in T2 and T1 respectively. Similarly, fat (5.12%) and ash (4.68%) levels for T3 were higher than 4.85% and 4.46% fat with 4.36% and 3.98% ash contents for T2 and T1 respectively. Results of mean scores for each organoleptic property decreased significantly (p<0.05) during storage period with no consistent trend in score pattern.

African leaves (Vernonia amygdalina Delile.) contain flavonoids having an antioxidant activities. The research aimed to determine the nephrotherapy effect of the ethanolic extract of African leaves with the parameter of male rat urea (Rattus norvegicus) induced by gentamicin. The research used 18 rats divided into 6 groups consisting of group I as the normal group, group Il the Negative Control (gentamicin 80 mg I kgBW), group Ill the Positive Contfol (amino acid supplement), group IV, V, and VI given the ethanol extract of African leaves, each dose of 100 mg/kgBW, 250 mg/kgBW, 500 mg/kgBW. The induction of gentamicin 80 mg/kg BW was administered for eight days and the therapy for the ethanol extract of African leaves for fourteen days. The research data were statistically analyzed using the ANOVA test followed by the Post Hoc LSD test. The results showed that the ethanol extract of African leaves had the nephrotherapy effects in reducing the urea in male rat induced by gentamicin.

Aeromonas spp, ubiquitous in both terrestrial and aquatic environments are becoming renowned as enteric pathogens of serious public health concern as they have a number of virulence and resistant determinants that are linked to both human and aquatic diseases due to consistent and incorrect use of antibiotics in aquaculture. The effect of crude aqueous and ethanol extracts of some medicinal plants on antimicrobial resistant Aeromonas spp. isolated from aquaculture water and fish samples was studied. Two hundred and forty (240) Aeromonas isolates, made up of 168 Aeromonas hydrophila and 72 Aeromonas salmonicida, were recovered from aquaculture water and fish gill samples collected from different commercial fish ponds using selective media. The isolates were assessed for their antibiotic susceptibility against ten (10) conventional antibiotics using the Kirby-Bauer technique. Extracts from three medicinal plants, Vernonia amygdalina, Ocimum gratissimum and Garcinia kola were also analyzed for their antimicrobial effects on the isolates that were resistant to the conventional antibiotics. Aeromonas hydrophila isolates expressed the highest resistant rates of 100%, 78.6% and 70.8% to aztreonam, cefotaxime and neomysin respectively, and the A. salmonicida isolates also had a similar trend of high resistant rates of 100%, 87.5% and 77.8% to aztreonam, neomysin and cefotaxime respectively. Antimicrobial resistant analyses with the plant extracts showed 100% inhibition of the isolates at 100 mg/ml for both aqueous and ethanol extracts. Phytochemical screening identified the presence of certain phytochemicals like alkaloids, saponins, tannins, flavonoids, steroids and glycosides which could have accounted for the antimicrobial effects of the plant extracts under study. It can be inferred then, that extracts from Vernonia amygdalina, Ocimum gratissimum and Garcinia kola can inhibit resistant aquaculture Aeromonas isolates and so can present an alternative source of antimicrobials in the effort to combat the increasing incidence of antimicrobial resistance in aquaculture.
