    Opis:
    Methicillin Resistant Staphylococcus aureus (MRSA) is an important nosocomial pathogen causing a significant mortality and morbidity. The main objective of the study was to establish antibiotic susceptibility pattern MRSA isolated from pediatrics clinical samples at Webuye District Hospital. A total of 96 clinical samples that include blood, abscess, ear swabs, and urine and wound/pus swabs were collected by simple random techniques. These samples were cultured onto Blood agar and MacConkey agar respectively and incubated at 37oC for 24 hours. In the result 83 (86.5%) clinical samples had pure colonies of S. aureus which were identified morphologically and biochemically by standard laboratory procedures using Bergey’s Manual of Clinical Microbiology. All confirmed positive isolates were screened for MRSA whereby 18 (21.7%) were MRSA and these were subjected to susceptibility testing to common antibiotics by modified Kirby-Bauer disc diffusion method. The susceptibility was interpreted according to National Clinical laboratory Standard guidelines. From the study the prevalence of MRSA was 18 (21.7%) with the highest obtained in the wound/pus swab. Almost all MRSA was resistant to penicillin (92.8%) and cephalexin (96.6%) and amoxicillin (91%). The most effective antibiotics against the of MRSA strain were vancomycin (98.97%), ciprofloxacin (88.4%) and gentamycin (83.06%). Vancomycin was the most effective drug showed the largest inhibition zone.

    Opis:
    We study the bound state solutions of the Klein-Gordon equation with Woods-Saxon plus attractive inversely quadratic potential using the parametric Nikiforov-Uvarov Method. We obtained the bound state energy eigenvalues and the corresponding normalized eigen functions expressed in terms of hypergeometric functions. Two special cases of this potential are discussed.

    Opis:
    The solutions of the Schrӧdinger equation with Manning-Rosen plus a class of Yukawa potential (MRCYP) have been presented using the Pekeris-like approximation and parametric Nikiforov-Uvarov (NU) method. The bound state energy eigenvalues and the corresponding un-normalized eigen functions are obtained in terms of Jacobi polynomials. Also, inversely quadratic Yukawa, Yukawa, Manning-Rosen and coulomb potentials have been recovered from the mixed potential and their Eigen values obtained. The Numerical results are computed for some values of n at l = 0 with α = 0.01, 0.1, 2 and 5 using python 3.6 programming, and these results could be applied to molecules moving under the influence of MRYP potential as negative energy eigenvalues obtained indicate a bound state system.

    Opis:
    Plant extracts have been used widely with and without chemical modification for various infectious diseases cause by bacterial activities. All the methanolic plant extract of Sclerocarya birrea showed anti-microbial activities against most of the test organism with some showing a better antibacterial and antifungal activities than others. The leave from Kem has the minimum bactericidal/fungicidal concentration of 50 mg/ml for E. coli, 100 mg/ml for C. albican and S. aureus but A. niger has 200 mg/ml whereas on the other hand from Yola S. aureus, C. albican, A. niger and E. coli has 100 mg/ml. The stem has the minimum bactericidal and fungicidal concentration of 50 mg/ml for E. coli, S. aureus and 100 mg/ml for C. albican and A. niger and on the other hand from Yola has 100 mg/ml for E. coli, S. aureus and 200 mg/ml for C. albican and A. niger. The roots from Kem has 50 mg/ml for E. coli and S. aureus and 100 mg/ml for C. albican and A. niger and from Yola has 100 mg/ml for E. coli, S. aureus, C. albican and A. niger has 200 mg/ml. This shows that the stem and roots of Sterculia Setigera is more sensitive to the tested organism and is bactericidal at low concentration. The leaves extract in both locations has the MIC of 50 mg/ml for E. coli, S. aureus and C. albican but 100 mg/ml for A. niger. The stem extract from Kem has the MIC of 25 mg/ml for bacteria and 50 mg/ml for fungi and on the other hand from Yola, the extract has MIC of 50 mg/ml for E. coli, S. aureus and C. albican but 100 mg/ml for A. niger. The root showed different minimum inhibitory concentration from Kem, the extract has 25 mg/ml for bacteria and 50 mg/ml for fungi. On the other hand, the extract from Yola has 50 mg/ml for bacteria and 100 mg/ml for fungi. Finally, the limit of detection for both plants collected from two different geographical areas for inhibitory effect has been measured successfully.
