    Gari agar as culture media for mycological studies
    (International Formulae Group, 2013-06) Okorondu, S. I.; Akujobi, C. O.; Okorondu, J. N.; Okorondu, M. M. O.
    Gari agar was prepared by weighing 28 g of Gari, 14 g of agar powder and 8 g of Hibiscus rabdariffa powder to 1 L of sterile water. A conventional media, Sabouraud Dextrose Agar (SDA) was prepared as control according to manufacturer’s procedure. Aliquot of appropriate dilutions of 1 g of agricultural soil was inoculated onto SDA and Gari agar by pour plate technique and spread plate technique. After 2 days and 4 days of inoculation, the growth of moulds was examined. Fungal colonies on Gari agar were very healthy and compared favourably with fungal growth on Sabouraud dextrose agar which is a conventional medium. Gari agar produced healthy moulds as determined by diameter of growth. Furthermore, conventional media (SDA) supported the growth of bacteria while Gari agar inhibited the growth of bacteria and promoted that of fungi. Cassava can be successfully grown in poor soils with low labour requirement, low capital and ease of cultivation. Gari extract agar can now be used successfully for quantitative count of moulds. The result of this study will go a long way in solving the problem of high cost of conventional media used as culture media for mycological studies.

    Prevalence and antibiotic sensitivity profile of urinary tract infection pathogens among pregnant and non pregnant women
    (International Formulae Group, 2013-08) Okorondu, S. I.; Akujobi, C. O.; Nnadi, C. B.; Anyado-Nwadike, S. O.; Okorondu, M. M. O.
    The prevalence and antibiotic sensitivity profile of urinary tract infection isolates from 100 pregnant women attending antenatal clinic in Owerri General Hospital, Nigeria was assessed. The prevalence of UTI isolates from the pregnant women was compared with that in non-pregnant women. The organisms isolated include: Escherichia coli, Staphylococcus aureus, Coagulase negative Staphylococcus, Klebsiella spp, Pseudomonas spp, Proteus spp and Streptococcus spp. Antibiotic sensitivity pattern of the isolates were also determined using disk diffusion test. One hundred (100) women were tested; 40% had bacteriuria as against 31% in non-pregnant women. The most sensitive isolate was E. coli, while the least was Streptococcus spp. The most effective antibiotics were Gentamycin, Tarivid and Ciprofloxacin, while the least occurred with Chloramphenicol, Ampicillin, Septrin, Ampiclox. Improvement on personal hygiene and diagnostic screening and treatment will help to reduce the prevalence of bacteriuria in pregnancy. There is also the need for regular antibiotic survey as this will ensure up to date information on the usefulness of the various antibiotics to treat infection thereby avoiding drug resistance as a result of continuous usage of drugs that are not sensitive to some microorganisms.
