ABSTRACT Galangal rhizome traditionally used to treat diseases. Red galangal rhizome contains flavonoid compounds, which are thought to be able to inhibit the growth of bacteria. Urinary tract infections are infections that occur due to the proliferation of microorganisms in the urinary tract. This study aims to determine the antibacterial activity of non-polar extracts of red galangal (Alpinia purpurata K.Schum) against the growth of Klebsiella pneumoniae bacterial urine isolates in urinary tract infections. Extraction was carried out by maceration method using n-hexane solvent. The antibacterial activity was testing using the paper disc diffusion method (Kirby and Bauer diffusion). The results showed that the inhibitory activity of extracts with concentrations of 80%, 40%, 20%, and 10% of the average diameter of the clear zone were 11.03 mm, 8.75 mm, 7.1 mm and 6.03 mm. Shows that the inhibition at 80% concentration is strong, while at 40% concentration, 20% is moderate and at 10% concentration is moderate. Based on this study it can be concluded that the non-polar extract of red galangal can inhibit the bacteria Klebsiella pneumoniae urine isolate in urinary tract infections. Keywords: Red Galangal Rhizome, Antibacterial, Inhibition  ABSTRAK Rimpang lengkuas secara tradisional digunakan untuk mengobati penyakit.

AbstractThe search for new antimicrobials is essential to address the worldwide issue of antibiotic resistance which affects all areas requiring the use of antibiotics including the management of diseases such as urinary tract infections (UTIs).AimTo assess the antimicrobial activity of ethanolic and aqueous extract of Aesculus hippocastanum L. (horse chestnut) bark.Material and MethodBioactive compounds were extracted from A. hippocastanum bark using water and ethanol as solvent. The extracts were tested against 10 clinical strains isolated from urine of patients diagnosed positive to urinary tract infections and including five Gram-positive bacteria (Kocuria rhizophila 1542, Enterococcus avium 1669, Staphylococcus simulans 5882, Conybacterium spp 1638, Enterococcus faecalis 5960) and five Gram-negative (Proteus mirabilis 1543, Morganella morganii 543, Citrobacter freundi 426, Acynetobacter baumannii 5841 and Achromobacter xylosoxidans 4892). Staphylococcus aureus ATCC 6538 and Escherichia coli ATCC 25922 were used as standard Gram+ and Gram-respectively. The susceptibility of the test strains to antibiotic was assessed using the Kirby Bauer disc diffusion method while the antibacterial activity of the extracts was evaluated using the well diffusion method. We finally determined the Minimum inhibitory concentration (MIC) and the minimum bactericidal concentrations (MBC) by the microdilution method.ResultsA. hippocastanum bark possessed a dry matter content of 65.73%. The volume yield of the ethanolic and aqueous extract (AE) was 77,77% and 74,07% (v/v), respectively, whereas their mass yields were 13,4% and 24,3% (w/w), respectively. All the bacteria were susceptible to amoxiclav, imipenem and ceftriaxone, both standard bacteria (E. coli ATCC 25922 and S. aureus ATCC 6538) were sensitive to all antibiotics while the clinical strains were resistant to at least one antibiotic. K. rizophilia 1542 and Conybacterium spp 1638 were the most resistant bacteria both with multidrug resistance index of 0.45. Except AE on P. Mirabilis 1543 and E. faecalis 5960 (0 mm), both AE and EE were active against all the microorganisms tested with inhibition diameters (mm) which ranged from 5.5-10.0 for AE and 8.0-14.5 for EE. The MICs of EEs varied from 1-4 mg/ml while those of EAs varied from 4-16 mg/ml. Almost all the MBCs of AEs were indeterminate (>64 mg/ml) while those of EE were successfully determined. The ethanolic extracts (EE) were overall more active than the aqueous ones.ConclusionThe A. hippocastanum bark extracts had overall weak antibacterial activity (MIC ≥0.625 mg/ml) and bacteriostatic potential (MBC/MIC ≥16) on both Gram-positive and Gram-negative bacteria. Therefore, studies with other solvents (such as methanol and chloroform), other extraction techniques, and synergy tests with conventional antibiotics are needed to conclude on a potential better antimicrobial activity of this plant material.

Klebsiella pneumoniae is one of the important clinical organisms that causes various infectious diseases, including urinary tract infections, necrotizing pneumonia, and surgical wound infections. The increase in the incidence of multidrug-resistance K. pneumoniae is a major problem in public healthcare. Therefore, a novel antibacterial agent is needed to treat this pathogen. Here, we studied the in vitro and in vivo activities of a novel antibiotic LCB10-0200, a siderophore-conjugated cephalosporin, against clinical isolates of K. pneumoniae. In vitro susceptibility study found that LCB10-0200 showed potent antibacterial activity against K. pneumoniae, including the beta-lactamase producing strains. The in vivo efficacy of LCB10-0200 was examined in three different mouse infection models, including systemic, thigh, and urinary tract infections. LCB10-0200 showed more potent in vivo activity than ceftazidime in the three in vivo models against the drug-susceptible and drug-resistant K. pneumoniae strains. Taken together, these results show that LCB10-0200 is a potential antibacterial agent to treat infection caused by K. pneumoniae.

Abstract: Catheter associated urinary tract infection's (CAUTI) account for more than 80% of all healthcare associated infections (HAIs) as compared to non-catheterized urinary tract infections. Catheter associated urinary tract infections occur on the third day after insertion of catheter in patients having urinary tract infection (UTI). In long term catheter use, bio-film form along the catheter which increases the risk of antibiotic resistant pathogens. Most common pathogens involved were Escherichia coli and Klebsiella pneumoniae which produce the enzymes Extended Spectrum β-Lactamases (ESBLs). Objective: To compare the frequency of ESBLs in catheterized and non-catheterized UTI infections. Materials and Methods: This comparative study was conducted at the Microbiology Department, Allama Iqbal Medical College, Lahore, from June 2014 to January 2015. Urine samples were cultured according to WHO protocol and antimicrobial Susceptibility testing was performed by Modified Kirby-Bauer disc diffusion Method. Escherichia coli and Klebsiella pneumoniae were tested for ESBL production by phenotypic confirmatory method of disk diffusion synergy using a disc of amoxicillin-clavulonate (30μg) and ceftrixone (30μg), cefotaxime (30μg) and aztreonam (30μg) discs. Results: Out of 300 positive urinary isolates of Escherichia coli and Klebsiella pneumoniae from CAUTI, 65.33% were ESBL producing isolates whereas out of 300 positive urinary isolates of Escherichia coli and Klebsiella pneumoniae from non-catheterized UTI, 47.66% were ESBL producing isolates. The results were highly significant (p < 0.001). Conclusion: Results showed that frequency of ESBLs were higher in catheterized patients as compared to non-catheterized patients. This is suggestive of a need for regular screening and surveillance for ESBL producing organisms. Patients infected with these organisms should be nursed with contact precautions to avoid the spread of nosocomial infection.

One of the most frequent chronic complications occurred in diabetes patients are the urinary tract infections (UTIs). This study aimed to investigate the incidence of UTIs in a cohort of 93 (47 males: 46 females) diabetic patients, the prevalence of different microbial species involved and their virulence and antibiotic resistance profiles. The identification of the uropathogenic strains in the positive urine samples was performed using conventional methods and API tests. After identification, the antibiotic susceptibility profiles were established by the standardized disk diffusion method and double disk diffusion test was performed for the confirmation of ESBL and inducible AmpC b �lactamase phenotypes. The isolated strains were tested for the production of different cell associated and soluble virulence factors, i.e.: bacterial adherence to cellular substrata (HeLa cells), hemolysins (hemolysis spot, CAMP-like), amylase, caseinase, aesculin hydrolysis, DNA-ase, lipase and lecithinase. In the analyzed group, the total prevalence of UTIs was of 46%, a higher incidence being observed in the female patients (64%). Similar to other studies, the etiology of UTI in the investigated diabetes patients was dominated by E. coli, followed by Klebsiella sp. strains. The isolated strains preserved good susceptibility rates to quinolones and aminoglycosides and revealed important virulence features, related to their capacity to colonize the cellular substratum and to produce soluble virulence factors involved in persistence, colonization and progression of the infectious process. The high percentage of beta-lactam resistant strains (including carbapenem-resistant ones) requires careful surveillance of the dynamics of susceptibility profiles for limiting the emergence of these strains in community.

Abstract Background Urinary tract infections (UTIs) are one of the most common bacterial infections. There is a lack of large epidemiologic studies evaluating the etiologies of UTIs in the United States. This study aimed to determine the prevalence of different UTI-causing organisms and their antimicrobial susceptibility profiles among patients being treated in a hospital setting. Methods We used the Premier Healthcare Database. Patients with a primary diagnosis code of cystitis, pyelonephritis, or urinary tract infection and had a urine culture from 2009- 2018 were included in the study. Both inpatients and patients who were only treated in the emergency department (ED) were included. We calculated descriptive statistics for uropathogens and their susceptibilities. Multi-drug-resistant pathogens are defined as pathogens resistant to 3 or more antibiotics. Resistance patterns are also described for specific drug classes, like resistance to fluoroquinolones. We also evaluated antibiotic use in this patient population and how antibiotic use varied during the hospitalization. Results There were 640,285 individuals who met the inclusion criteria. Females make up 82% of the study population and 45% were age 65 or older. The most common uropathogen was Escherichia Coli (64.9%) followed by Klebsiella pneumoniae (8.3%), and Proteus mirabilis (5.7%). 22.2% of patients were infected with a multi-drug-resistant pathogen. We found that E. Coli was multi-drug resistant 23.8% of the time; Klebsiella pneumoniae was multi-drug resistant 7.4%; and Proteus mirabilis was multi-drug resistant 2.8%. The most common antibiotics prescribed were ceftriaxone, levofloxacin, and ciprofloxacin. Among patients that were prescribed ceftriaxone, 31.7% of them switched to a different antibiotic during their hospitalization. Patients that were prescribed levofloxacin and ciprofloxacin switched to a different antibiotic 42.8% and 41.5% of the time, respectively. Conclusion E. Coli showed significant multidrug resistance in this population of UTI patients that were hospitalized or treated within the ED, and antibiotic switching is common.

Urinary tract infections (UTIs) represent a serious global health issue, especially due to emerging multidrug-resistant UTI-causing bacteria. Recently, we showed that the human amniotic membrane (hAM) could be a candidate for treatments and prevention of UPEC and Staphylococcus aureus infections. However, its role against multidrug-resistant bacteria, namely methicillin-resistant S. aureus (MRSA), extended-spectrum beta-lactamases (ESBL) producing Escherichia coli and Klebsiella pneumoniae, vancomycin-resistant Enterococci (VRE), carbapenem-resistant Acinetobacter baumannii, and Pseudomonas aeruginosa has not yet been thoroughly explored. Here, we demonstrate for the first time that the hAM homogenate had antibacterial activity against 7 out of 11 tested multidrug-resistant strains, the greatest effect was on MRSA. Using novel approaches, its activity against MRSA was further evaluated in a complex microenvironment of normal and cancerous urinary bladder urothelia. Even short-term incubation in hAM homogenate significantly decreased the number of bacteria in MRSA-infected urothelial models, while it did not affect the viability, number, and ultrastructure of urothelial cells. The hAM patches had no antibacterial activity against any of the tested strains, which further exposes the importance of the hAM preparation. Our study substantially contributes to basic knowledge on the antibacterial activity of hAM and reveals its potential to be used as an antibacterial agent against multidrug-resistant bacteria.

Background: Emergence of multi-drug resistant uropathogenic E. coli strains is an increasing problem to empirical treatment of urinary tract infections in many countries. This study investigated the magnitude of this problem in Jordan. Methods: A total of 262 E. coli isolates were recovered from urine samples of Jordanian patients which were suspected to have urinary tract infections (UTIs). All isolates were primarily identified by routine biochemical tests and tested for antimicrobial susceptibility by disc diffusion method. Fifty representative Multidrug Resistance (MDR) E. coli isolates to 3 or more antibiotic classes were tested for the presence of resistance genes of blaCTX-M- 1, 9 and 15, carbapenemase (blaIMP, blaVIM, blaNDM-1, blaOXA-48), fluoroquinolones mutated genes (parC and gyrA) and clone of ST131 type using PCR methods. Results: A total of 150/262 (57.3%) of E. coli isolates were MDR. Urine samples of hospitalized patients showed significantly more MDR isolates than outpatients. Fifty representative MDR E. coli isolates indicated the following molecular characteristics: All were positive for mutated parC gene and gyrA and for ST131 clone, and 78% were positive for genes of CTX-M-15, 76% for CTX-M-I and for 8% CTX-M-9, respectively. Additionally, all 50 MDR E. coli isolates were negative for carbapenemase genes (blaIMP, blaVIM, blaNDM-1, blaOXA-48), except of one isolate was positive for blaKPC-2 . Conclusion: This study indicates alarming high rates recovery of MDR uropathogenic E. coli from Jordanian patients associated with high rates of positive ST131 clone, fluoroquinolone resistant and important types of blaCTX-M.
