Objective: This research aims to evaluate the antibacterial activity and determine the chemical composition of the aqueous extract of the bark of Lannea barteri Engl. (DA) used in the traditional treatment of urinary tract infections in the Ivory Coast.Methods: The material is composed of DA, the bacterial strains of Pseudomonas aeruginosa and Acinetobacter baumannii, isolated from the urine of patients from different hospitals and subsequently stored. The qualitative analysis was performed using color-based detection tests and thin layer chromatography (TLC) reactions and the quantification of total phenols, flavonoids, flavone aglycones and anthocyanins using the method of Folin Ciocalteu. The method of diffusion on Mueller Hinton (MH) agar medium has been used for sensitivity tests. Results: The phytochemical screening of DA has revealed the presence of polyphenols, terpenes, and derivatives, coumarins, tannins, flavonoids, and alkaloids. Furthermore, the quantification of some polyphenols such as flavonoids, flavone aglycones, and anthocyanins was determined. The total polyphenols found was 0.757±0.003 mg/g MS representing respectively; 0.230±0.01 for flavonoids; 0.028±0.02 for flavone aglycones and 0.016±0.02 mg/g MS for anthocyanins. DA is bactericidal against Pseudomonas aeruginosa and Acinetobacter baumannii, which are mainly responsible for urinary tract infections.Conclusion: The bark of Lannea barteri Engl. (DA) is rich in flavonoids, flavone aglycones, and anthocyanins which are probably responsible for its antibacterial properties on Pseudomonas aeruginosa and Acinetobacter baumannii. This research thereby supports the use of this plant in the treatment of urinary tract infections.

Urinary tract infection is commoner in patients with spinal cord injuries because of incomplete bladder emptying and the use of catheters that can result in the introduction of bacteria into the bladder. 145 patients suffering from spinal cord injuries, admitted to the Institute for physical medicine and rehabilitation, Centre for paraplegia of the Clinical Centre of the University of Sarajevo, were included. The patients were divided in three groups according to the method of bladder drainage: Group A (n=61) consisted of patients on clean intermittent catheterization; Group B (n=54) consisted of patients with indwelling catheters; Group C (n=30) consisted of patients who had performed self-catheterization. From a total of 4539 urine samples, 3963 (87,3%) were positive and 576 (12,7%) were sterile. More than 90% of the infected patients were asymptomatic.The overall rate of urinary infection amounted to about 2,1 episodes, and bacteriuria to 8,1 episodes per patient. 77% of infections (113/145) were acquired within seven days from catheterization.Infection was usually polymicrobial; the greatest number of urine samples 1770/3943 (44,9%) included more than one bacterium.The vast majority of cases of urinary tract infection and bacteriuria are caused by Gram-negative bacilli and enterococci, commensal organisms of the bowel and perineum, representative of those from the hospital environment. Providencia stuarti (18,9%) being the most common, followed by Proteus mirabilis (16,3%), Escherichia coli (11,8%), Pseudomonas aeruginosa (10,2%), Klebsiella pneumoniae (8,1%), Morganella morgani (5,4%), Acinetobacter baumannii (4,6%), Providencia rettgeri (3,5%). 15,7% of isolates were Gram-positive with Enterococcus faecalis (8,6%) as the most common. 55,3% of isolates were multidrug-resistant, and the highest rates of resistance were found among Acinetobacter baumannii (87,8%), Providencia rettgeri (86,7%), Pseudomonas aeruginosa (85,4%), Providencia stuarti (84,3%) and Morganella morgani (81,0%). Lower rates of resistance were found in Group C, i.e. patients on intermittent self- catheterisation. Eradication of organisms was achieved in only 53 (10,05%) of patients; hence, antibiotic therapy had no or very low effect.Significant correlations were found between the method of catheterization and the frequency of bacteriuria and urinary tract infections. The analysis of Group C showed a rate of lower urinary tract infection and bacteriuria than the other two Groups of patients. The objective of this study is the update of etiology and antimicrobial susceptibility in urinary tract infections in this group of patients. In addition, possible correlations between UTI and the type of bladder management were examined.

Abstract Background In recent years, less options are available for treating carbapenem-resistant Acinetobacter baumannii and carbapenem-resistant Pseudomonas aeruginosa. The present study investigatesthe susceptibility rates to imipenem/relebactamfor the treatment of intra-abdominal infections (IAIs), respiratory tract infections (RTIs) and urinary tract infections (UTIs) caused by A. baumannii and P. aeruginosain China. Methods 1,886 P. aeruginosa and 1,889 A.baumanniiisolates were collected in 21 centers (7 regions) as part of the global SMART surveillance program between 2015 and 2018. Antimicrobial susceptibility testing was performed according tothe Clinical and Laboratory Standards Institute (CLSI) recommendations using the broth microdilution methodology in the Peking Union Medical College Hospital. Results Rates of imipenem-non-susceptibilities of P. aeruginosa and A. baumanniiisolates were 44.3% and 79.0%, whereas the multidrug-resistance (MDR) rateswere 44.3% and 81.9%, respectively.For P. aeruginosa, susceptibility rates to imipenem/relebactamwere 84.2% at aCLSI breakpoint of ≤ 2 mg/L compared to 55.7% for imipenem. The MIC90 of imipenem/relebactam(8 mg/L) was one fourth of that of imipenem (32 mg/L).The susceptibilities of imipenem-non-susceptible and MDRP.aeruginosastrains were similarly restored by imipenem/relebactam in non-ICU and ICU wards.The susceptiblity rate of A. baumannii isolates to imipenem was 21.0% and to imipenem/relebactam 22.2%. Conclusions Imipenem/relebactam provides a therapy option for infections caused by MDRor imipenem-non-susceptible P. aeruginosa infections in China.

       Current study obtained (75) isolate of Pseudomonas aeruginosa collected from different cases included : 28 isolates from otitis media, 23 isolates from burn infections, 10 isolates from wound infections, 8 isolates from urinary tract infections and 6 isolates from blood, during the period between 1/9/2014 to 1/11/2014        The result revealed that the tox A gene was present in 54 isolates (72%) of Pseudomonas aeruginosa. The gel electrophoresis showed that the molecular weight of tox A gene was 352 bp. The result shows 17 isolates (60.71%) from otitis media has tox A gene, 18 isolates (78.26%) from burn followed by 8 isolate (80%) from wound infection and 5 isolates (62.5%) from urinary tract infection , finally 6 isolates (100%) from blood have this gene.

Pseudomonas aeruginosa is one of the most important opportunistic pathogens responsible for various types of hospital infections. High prevalence of antibiotic resistance in P. aeruginosa strains of human clinical samples cause more severe diseases for a longer period of time. The current research was done in order to study the distribution of blaIMP-1 gene among the imipenem-resistant P. aeruginosa strains isolated from burn and urinary tract infections of hospitalized patients. Two-hundred and forty-three P. aeruginosa isolates recovered from the cases of burn and urinary tract infections of inpatients and outpatients were analysis for antibiotic resistance pattern using the disk diffusion method. Then, imipenem-resistant isolates were further analyzed for distribution of blaIMP-1 gene using the PCR. Of 243 P. aeruginosa isolates, 146 strains (60.08%) were taken from outpatients and 97 strains (39.91%) were taken from inpatients. P. aeruginosa isolates harbored the highest levels of resistance against streptomycin (100%), nalidixic acid (100%), aztreonam (100%), cotrimoxazole (95.47%), ciprofloxacin (88.47%), cefotaxime (84.36%) and gentamycin (83.95%). Inpatients had a relatively higher levels of antibiotic resistance. One-hundred and twenty-one out of 126 (96.03%) imipenem-resistant P. aeruginosa isolates harbored the blaIMP-1 gene. Inpatients also had a relatively higher prevalence of blaIMP-1 gene. High prevalence of blaIMP-1 gene and also imipenemresistant P. aeruginosa are important public health issue. Clinical laboratories should consider the detection of the blaIMP-1 gene among the P. aeruginosa isolates of clinical samples.
