This study was conducted in 124 children with meningitis to review the etiology, antimicrobial susceptibility and outcome of disease in a Nigerian tertiary health facility. Of these, 97 (78.27%) were culture positive; in the rest 27(21.8%), diagnosis was based on Gram staining of the CSF. Streptococcus pneumoniae, Haemophilus influenzae, Neisseria meningitidis, Staphylococcus aureus and Escheri...

A 68-year-old man on peritoneal dialysis (PD) was hospitalized with the clinical picture of peritonitis. The patient was diagnosed with peritonitis caused by nontuberculous mycobacteria (NTM) according to positive Ziehl-Neelsen staining and negative Mycobacterium tuberculosis polymerase chain reaction results. Oral levofloxacin and clarithromycin, and later intraperitoneal imipenem were started...

We report a catalase-negative Staphylococcus aureus isolated from a 56-year-old male diabetic patient with foot ulcer who attended our surgery ward. Species identification was confirmed by Gram staining, standard biochemical tests and PCR amplification of the nuc and fem genes. Antibiotic susceptibility showed that the strain was sensitive to imepenem, chloramphenicol, amoxicillin, vancomycin a...

Chromomycin A3 binds to DNA and Protamine -deficient spermatozoa look bright yellow,whereas normal spermatozoa appear dull yellow.

A machine is described which can perform the Gram stain. Comparison of slides stained by machine versus hand revealed no difference in reproducibility or accuracy. In addition to providing clean, dry, uniformly stained slides, the machine saves 24 sec per slide when compared with a hand staining technique.

A wet-mount technique for staining bacterial flagella is highly successful when a stable stain and regular slides and cover slips are used. Although not producing a permanent mount, the technique is simple for routine use when the number and arrangement of flagella are critical in identifying species of motile bacteria.

PURPOSE To determine whether, by employing recent advances in immunocytochemical technique, it is possible to identify reliably the product of the retinoblastoma (RB) susceptibility gene, p110RB1, in formalin-fixed, paraffin-embedded eyes with commercially available primary antibodies. If so, the authors sought to determine the distribution of p110RB1 in normal human eyes and retinoblastomas in...
