Madam, this is in reference to an article titled “Antibiotic Susceptibility of Streptococcus Pneumoniae in Karachi” published in JPMA Vol. 50, No.2, February 2000. in the Results the authors have reported 100% susceptibility to amoxyci Ilin—clavulanate whereas the same isolates have 80.2% susceptibility to penicillin and the rest 19.8% are having intermediate status. These results suggest that ...

OBJECTIVES Urinary tract infection is the second most common clinical indication for empirical antibiotic treatment in primary and secondary health care settings. The incidence of diabetes mellitus throughout the world is increasing strikingly and in the long run, it has some major effects on the genitourinary system which makes diabetic patients more liable to urinary tract infection. This stu...

OBJECTIVE. The purpose of this narrative review was to evaluate the antimicrobial activity garlic (_Allium sativum_), thyme (_Thymus vulgaris_), oregano (_Origanum vulgare_), turmeric (_Curcuma longa_), rosemary (_Rosmarinus officinalis_) and cinnamon (_Cinnamomum _species) for treatment antibiotic-resistant strains _Staphylococcus aureus, Streptococcus pneumoniae, Pseudomonas aeruginosa, Esche...

Erythromycin-resistant Streptococcus pneumoniae isolates from young carriers were tested for their antimicrobial susceptibility; additionally, inducibility of macrolide and clindamycin resistance was investigated in pneumococci carrying erm(A), erm(B), or mef(A). Of 125 strains tested, 101 (81%) were multidrug resistant. Different levels of induction were observed with erythromycin, miocamycin,...

Although the rate of acylation of a penicillin-resistant form of Streptococcus pneumoniae penicillin-binding protein 2x (PBP2x) by ceftaroline is 80-fold lower than that of its penicillin-sensitive counterpart, it remains sufficiently high (k(2)/K = 12,600 M(-1) s(-1)) to explain the sensitivity of the penicillin-resistant strain to this new cephalosporin. Surprisingly, the Actinomadura R39 DD-...

UNLABELLED (Full text is available at http://www.manu.edu.mk/prilozi). In recent decades, the increase of Streptococcus pneumoniae strains resistant to beta-lactams, to other classes of antimicrobial drugs and especially to penicillin (penicillin-resistant pneumococcus - PRP) has further complicated the treatment of pneumococcal infection. Penicillin resistance in pneumococci is due to the deve...

conclusions our results indicated that the dissemination of pi-1 was widespread in s. pneumoniae isolates, although no pi-2 isolates were detected. furthermore, the frequency of rlra and rrgc of clinical isolates was significantly more than that of normal flora isolates. results the results confirmed the presence of rlra and rrgc genes in both clinical (n = 39) and normal flora (n = 26) isolate...

OBJECTIVE To determine the penicillin resistance and serotype distribution of Streptococcus pneumoniae strains and to identify clonal relationships of isolates resistant to penicillin by means of pulsed-field gel electrophoresis (PFGE). METHODS In total, 193 S. pneumoniae strains were isolated from clinical specimens between November 1997 and January 2000. Susceptibility testing was carried o...

Strains of Streptococcus pneumoniae resistant to penicillin have been reported from several countries around the world. Many South African isolates, in addition, exhibit resistance to tetracycline, chloramphenicol, erythromycin, clindamycin, and cotrimoxazole in varying patterns. A qualitative test of the ability of antibiotic-resistant pneumococci to inactivate penicillin, oxacillin, cephaloth...

A number of 7-substituted quinolone derivatives were synthesized and evaluated for antibacterial and cytotoxic activities. Preliminary results indicated that most compounds tested in this study demonstrated better activity against methicillin-resistant Staphylococcus aureus than norfloxacin. Among them, 1-(4-amino-2-fluorophenyl)-6-fluoro-1,4-dihydro-7-[4-[2-(4-methoxyphenyl)-2-hydroxyiminoethy...
