Preliminary phytochemical screening, proximate and elemental composition of Moringa Oleifera lam seed powder

The seed powder of Moringa oleifera was analysed for its phytochemical, proximate and elemental composition using Folin-Denis spectrophotometric method, gravimetric method and energy dispersing X-ray fluorescence (EDXRF) transmission emission technique respectively. The seed powder had the following proximate composition: nitrogen (2.98%), crude protein (18.63%), tannins (322.9 mg/100g), alkaloids (8.24 mg/100g) and saponins (9.13%). The predominant mineral elements in the seed powder were: Al (144 ± 4 ppm), Ca (602 ± 122 ppm), K (732 ± 164 ppm), P (0.619 mg/kg), Na (86.2 ± 4.9 ppm), Mn (17.5 ± 0.4 ppm), Br (0.62 ± 0.09 ppm), La (0.73 ± 0.13 ppm), Sm (0.14 ± 0.01 ppm), Rb (37.5 ± 6.7 ppm) and Sc (0.17 ± 0.03 ppm) while Mg, Fe, Cr, As, Th and Zn were all beyond detection limits. The results of the study suggest the pharmacological and nutritional potentials of M. oleifera seeds for human and other animal uses.

Antimicrobial susceptibility pattern of Aeromonas hydrophila among patients presented with diarrhea attending two teaching hospitals in northern, Nigeria

A total of one hundred and twenty eight (128) stool samples were collected from patients attending Ahmadu Bello University Teaching Hospital Zaria and Aminu Kano Teaching Hospital Kano, and screened for the presence of Aeromonas hydrophila infection. Out of the one hundred and twenty eight samples analyzed 4 (3.12%) were found positive for Aeromonas hydrophila infection. Antibioticsusceptibility testing of Aeromonas hydrophila isolated showed that all the 4 (100%) isolates were sensitive to Colistin and Ceftazidime, 3 (75%) to Augmentin and 2(50%) to Gentamicin and Cefuroxine. All the isolates (100%) were however resistant to Cotrimoxazole, Tetracycline, Sulphatriad, Streptomycin, Cephalothin and Ampicilin. This study confirmed that Aeromonas hydrophila as a sole enteropathogen could be responsible for diarrhea and should be considered amongst the causative agents of diarrhea.
