Background and Objectives: Bacteria that attach to the surfaces and produce polymeric matrix resulting in the biofilms formation are involved in a wider range of human infections. Biofilms forming Staphylococcus aureus and Escherichia coli are considered to be highly antibiotics resistant. This study aimed to analysis the antibiogram profile of biofilm forming S. aureus and E. coli in Mukalla city, Hadhramaut,Yemen.
Methods: Sixty clinical isolates of S. aureus and E. coli were isolated from different clinical samples, and identified by standard bacteriological methods, then subjected to biofilm formation detection by tissue culture plate (TCP) method. The antibiotics susceptibility test was performed by disc diffusion (Kirby-Bauer) method. Chi-square test was used to analyze the data and p value< 0.05 was taken as significant.
Results: Among the total isolates S. aureus and E. coli, TCP method detected 55% of isolates as strong, 25% as moderate and 25% as weak/non-biofilm producers. Biofilm forming of S. aureus developed significantly higher degrees of antibiotic resistance of amoxicillin/clavulanic acid100%, ceftazidime 95.8%, cefotaxime62.5%, cefadroxil 45.8%, ciprofloxacin 41.7% and ceftriaxone 25% with significant statistics correlation the resistance of amoxicillin/clavulanic acid and ceftazidime and bacterial biofilm production (p-value< 0.05). The rates of antibiotics resistance biofilm E. coli were 100%, 91.7%, 75%, 70.8%, 66.7%, 62.5% and 33.3%for amoxicillin/clavulanic acid, cefadroxil, cefotaxime, ceftazidime, ceftriaxone, ciprofloxacin and co-trimoxazole respectively with statistically significant correlation of cefadroxil resistance (p-value < 0.05).
Conclusion: TCP method showed that S. aureus and E. coli isolates have high degree of biofilm forming ability. A high antibiotics resistance found in biofilm producers isolates than non-biofilm producers.

UJPR follows the most transparent and toughest ‘Advanced OPEN peer review’ system. The identity of the authors and, reviewers will be known to each other. This transparent process will help to eradicate any possible malicious/purposeful interference by any person (publishing staff, reviewer, editor, author, etc) during peer review. As a result of this unique system, all reviewers will get their due recognition and respect, once their names are published in the papers. We expect that, by publishing peer review reports with published papers, will be helpful to many authors for drafting their article according to the specifications. Auhors will remove any error of their article and they will improve their article(s) according to the previous reports displayed with published article(s). The main purpose of it is ‘to improve the quality of a candidate manuscript’. Our reviewers check the ‘strength and weakness of a manuscript honestly’. There will increase in the perfection, and transparency.
