Introduction:Acinetobacter species is associated with health care associated infections especially in patients on respiratory therapy equipment and indwelling catheters. They are becoming increasingly drug resistant. The knowledge of the prevalence and pattern of antimicrobial susceptibility pattern of Acinetobacter spp. is important.AimsThe study is undertaken to estimate the prevalence rate, risk factors and antimicrobial resistance pattern of isolates. in Acinetobacter spp. from various clinical samples.Material and Methods:The isolates of Acinetobacter species obtained from various clinical specimen. Specimens were processed by standard microbiological techniques. Antimicrobial sensitivity tests of the Acinetobacter isolates were done by modified Kirby-Bauer disc diffusion method.ResultsOut of 622 isolates, 399 isolates were from inpatients (62,18%) and 223 were from outpatients (37,82%). More than 90% of isolates displayed resistance to ampicillin, amoxicillin-clavulanic acid, ceftazidime, caftriaxon and amikacin. Resistance to gentamicin, co-trimoxazole and ciprofloxacin were also common. Least resistance was seen to piperacillin-tazobactam and imipenem. A total of 125 Acinetobacter isolates were analyzed, out of which 78.4 % were multi-drug resistant (MDR). Of these MDR isolates, 17.24% were pan-resistant. A. baumannii was the most common species responsible for wound infection (84,8%), pneumonia(96,15%), abscess (72.7%), urinary tract infection (85,7%) and septicemia(89,5%).Conclusion:Multi-drug resistant Acinetobacter has emerged as an important nosocomial pathogen. Antibiotic susceptibility testing is critical in the treatment of infections caused by Acinetobacter. Continued surveillance of prevalent organisms in ICUs, combined with preventive measures remains absolutely essential in efforts to prevent or limit the spread of Acinetobacter infection.
Objectives:The aim of this study was to examine the presence of antimicrobial resistance / susceptibility strains of Escherichia coli in inpatients and outpatients.Materials and methods:It is a retrospective study carried out at the Department of Microbiology, Parasitology and Virology Faculty of Medicine, University of Sarajevo. In cooperation with the Microbiological laboratory of the Cantonal Hospital Zenica and the Microbiological laboratory of the General Hospital Tesanj, 3863 urine samples were processed in the period from March 1st to March 31st 2016.Results:Our study showed that E. coli had the highest antimicrobial resistance to trimethoprim / sulfamethoxazole (38.61%), followed by amoxicillin / clavulanic acid (19.62%), ciprofloxacin (9.49%), gentamicin (8.86%), cephalexin (8.23%), nitrofurantoin (8.23%), cefuroxime (7.52%), ceftazidime (6.33%), cefuroxime (89.87%), amikacin (4.43%).Conclusions:The isolated strains of E. coli showed the highest resistance to trimethoprim / sulfamethoxazole and amoxicillin / clavulanic acid. The isolated strains of E. coli showed the greatest susceptibility to amikacin and ceftazidime. Gender distribution of positive E. coli isolates showed statistically significant differences in favor of females.
Background Tumor development and growth are driven in many cases by inflammatory cells, which can produce cytokines and other factors that can stimulate the development of the malignant process. The aim of this study was to evaluate interleukin-6 (IL-6), C-reactive protein (CRP), matrix metalloproteinase-9 (MMP-9), serum levels in patients with colorectal cancer (CRC), and their association with the stage of CRC. Methods IL-6, MMP-9, and CRP serum levels were measured in 75 patients with CRC just before surgical treatment, as well as in 20 healthy individuals as controls. Surgically obtained tissue material was subjected to pathological analysis. Results Significant increase in CRP and IL-6 serum concentration is associated with increasing stage of CRC (p <0.05), where MMP-9 serum level was significantly higher in stages III and IV compared to the stage II CRC. Significant correlation was found between IL-6 and MMP-9 serum levels (rho=0.478; p <0.001) as well as between IL-6 and CRP serum levels (rho=0.720; p <0.001) and between MMP-9 and CRP serum levels (rho=0.379; p <0.001). Serum levels of MMP-9 and CRP have been shown to be independent predictors of the CRC stage. Conclusion Combined quantification of IL-6, MMP-9, and CRP serum levels seems to be a reliable index of inflammation-related processes during colorectal carcinogenesis.
Objectives:The main objective of the study was to identify the most frequent isolates from female outpatients with urinary tract infection.Material and methods:The retrospective study was performed at the Department of Microbiology, Parasitology and Virology Faculty of Medicine, University of Sarajevo in period of 2015. The most frequent isolates were determined in 405 first urine samples from female outpatients of Hrasno community in Sarajevo, B&H. Identification of isolates was performed by the standard microbiological testing and the standard methods of descriptive statistics as well.Results:E. coli was identified with the frequency of (67.21%), followed by Proteus spp. (9.83%), Enterococcus faecalis (7.37%) and Enterobacter (5.73%). Pseudomonas aeruginosa and Pseudomonas spp. were found in (2.45%), while the frequency of Klebsiella spp., Streptococcus spp. and Acinetobacter spp. was lower (1.63%).Conclusions:The isolated strains of E. coli pointed the highest frequency among female outpatients of Hrasno community.
Background:Methicillin resistant Staphylococcus aureus (MRSA) is responsible for a wide spectrum of nosocomial and community associated infections worldwide. The aim of this study was to analyze MRSA strains from the general population in Canton Sarajevo, B&H.Methods:Our investigation including either phenotypic and genotypic markers such as antimicrobial resistance, pulsed-field gel electrophoresis (PFGE), SCC typing, and Panton-Valentine leukocidin (PVL) detection.Results:Antimicrobial susceptibility: all MRSA isolates were resistant to the β-lactam antibiotics tested, and all isolates were susceptible trimethoprim sulphamethoxazole, rifampicin, fusidic acid, linezolid and vancomycin. Sixty-eight per cent of the MRSA isolates were resistant to erythromycin, 5% to clindamycin, 5% to gentamicin and 4% to ciprofloxacin. After the PFGE analysis, the isolates were grouped into five similarity groups: A-E. The largest number of isolates belonged to one of two groups: C: 60 (60%) and D: 27 (27%). In both groups C and D, SCCmec type IV was predominant (60% and 88, 8%, respectively). A total of 24% of the isolates had positive expression of PVL genes, while 76% showed a statistically significantly greater negative expression of PVL genes.Conclusion:SCCmec type IV, together with the susceptibility profile and PFGE grouping, is considered to be typical of CA-MRSA
