Prevalence of Some Uropathogenic Bacterial Isolates and their Susceptibility to Some Quinolones

Bacterial Isolates of different Genera were collected from suspected cases of Urinary tract infection in Ibadan and their prevalence was determined. Sensitivity pattern of the organisms to quinolone antibacterial agents was also investigated by the antibiotic disc diffusion method using Kirby Bauer method. The study revealed the prevalence of uropathogenic organisms as follows:- Escherichia coli (46.2%), Klebsiella spp (23.1%), Staphylococcus aureus (21.1%) and Pseudomonas aeruginosa (9.6%). The quinolones were found to be highly effective against all the organisms. The average percentage susceptibility of the organisms were as follow: Staphylococcus aureus (92.7%) Escherichia coli (81.7%), Pseudomonas aeruginosa (76.0%), and Klebsiella spp (70.0%). As indicated by their high activity, quinolones are better alternatives to commonly prescribed antibiotics in Urinary tract infection therapy although caution must be exercised in their prescription as the emerging low level of resistance may portend great danger for their future use

PERFORMANCE OF AN ACID-CASSAVA STARCH MEDIUM IN THE PROPAGATION OF FUNGI.

Propagation of mould and yeast isolates was carried out on a formulated acid-cassava starch medium (A-CSM) and commercial potato dextrose agar (PDA). The two media were also used to enumerate some of the fungal isolates. Cultural and morphological characteristics expected of filamentous fungi and those with transitional forms were observed on both A-CSM and PDA. Growth was more rapid in respect of most of the fungi on A-CSM but it was accompanied with minimal liquefaction, after 48 hrs of incubation. Similarly, the A-CSM produced greater viable counts of most of the fungi. The acid-cassava starch medium reported is considered a potential alternative to its equivalent commercial nutrient media such as PDA
