Bacterial otitis media in all age group of patients seen at Dessie referral hospital, North East Ethiopia

Spectrum of Microbial Isolates from Wound Infections in Patients admitted in a Tertiary Care Hospital, Kolkata

“…Though different studies throughout the world demonstrated poor correlation among the different methods of testing for polymyxin B and colistin, but some studies including our study demonstrated good correlation because of use of validated broth dilution method. Our study demonstrated that P. mirabilis (n = 55) was highly sensitive to piperacillin-tazobactam (90.90%), imipenem (83.63%), moderately sensitive to cefoperazonesulbactam (65.45%), ertapenem (65.45%), aminoglycoside group of antibiotics (60-69%), chloramphenicol (63.63%) which was partially similar to the studies done by Hailu et al, 33 Seid et al, 36 and Wasihun and Zemune. 39 These studies demonstrated low level of resistance (5-28%) to ciprofloxacin, piperacillin-tazobactam, ceftazidime, gentamicin, and ceftriaxone.…”

“…to 100% isolates of MRSA were resistant to penicillin and methicillin group of antibiotics, whereas in the study of Hailu et al, 33 65.4 and 34.6% S. aureus demonstrated resistance to penicillin and oxacillin respectively with more or less similar results were found in the study done by Hwang et al, 34 Abera et al, 35 and Seid et al 36 Our study as well as other different studies suggest that a largescale study is required on the prevalence and spectrum of susceptibility of community-acquired MRSA. The study showed 40 to 90% resistance to co-trimoxazole, chloramphenicol, ciprofloxacin, erythromycin with only 30% resistance to clindamycin, whereas only 0 to 31% resistance to ciprofloxacin, chloramphenicol, clindamycin, erythromycin, and co-trimoxazole was evidenced in the study done by Hailu et al, 33 Seid et al, 36 Abera and…”

“…Similarly, our study indicated very low level of sensitivity to ampicillin, amoxicillin, oxacillin which was also evidenced in the above studies. 33,36,39 The high resistance of P. aeruginosa, S. aureus, and P. mirabilis to ampicillin, amoxicillin, and oxacillin may be due to the following factors, like lack of up-to-date knowledge of antimicrobial resistance amongst nurses, physicians, lack of presence of proper antibiogram data, unnecessary, unethical, and irrational uses of antibiotics, self-intake by the patients, push by the pharmacists, irregular intake of antibiotics by the patients. Again, it is known fact that proteus species produces a unique beta-lactamase (cefuroximase) having high activity against cefuroxime, second-generation cephalosporin.…”

Bacterial etiology of acute otitis media among children attending Khartoum Ear Nose Throat Teaching Hospital in 2014

“…Abnormal anatomy and dysfunction of the tube are involved in the development of AOM. An infection in the nasopharynx and ET lead to increased mucous secretion that can obstruct the ET resulting in a negative middle ear pressure and the bacteria can then enter the middle ear (Kaltes, 2003 (Simon, 2009;Seid et al, 2013).…”
