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.

Abstract Microbial resistance to antibiotics represents a complex global, cross-border and intergenerational problem that requires interventions in due time, taking into consideration the enormous potential impact on human health. The purpose of this study is to evaluate the prevalence of extended-spectrum beta-lactamase producing bacteria (ESBL), carbapenemase-producing enterobacteriaceae (CPE) multidrug-resistant bacteria in urinary tract infections in the County Emergency Clinical Hospital of Târgu-Mureş during 2017-2018.

The results of several studies reveal that antibiotics may promote treatment resistance by causing alterations in the intestinal flora. The development of a gut reservoir of resistant bacteria promotes the development of UTIs through autoinfection. This review aims to address clinical reliability, efficacy and safety of long-term treatment with oral D mannose for the prevention of Recurrent Urinary Tract Infections (RUTI) in females. A comprehensive MEDLINE, Embase, Scopus and Cochrane search was performed for English language reports published before December 2018 using the term “recurrent urinary tract infections and D mannose” was carried out. We searched Medline, Embase, Scopus and the Cochrane Register of Controlled Trials from January 2010 to December 2018. Eligible studies did not include non-oral therapy, local (vaginal) treatment in women with recurrent UTIs. We identified eligible original articles. A few limitations of the review are the heterogeneity of the available studies, their different rational and aim, the assumption of D mannose for prophylaxis or treatment of recurrent UTIs. Oral D mannose performs well in the prevention of UTIs recurrences, significant improvement of urinary symptoms was observed, the disease- free time was longer in the groups of patients under prophylaxis with D mannose in comparison with control groups (no treatment, antibiotic prophylaxis, prophylaxis with Proanthocyanidin (PAC) etc. The review has limitations, as the studies are heterogeneous, the meta-analysis requires classifications that can also be arbitrary. Furthermore, single-arm studies are not included. Some of the authors found this evidence inconclusive, which results as a limitation of the study. D mannose prolonged the recurrence-free interval of recurrent UTIs, thus reducing the prolonged or cyclical use of antibiotics, improving clinical symptoms, with a significant difference between treatment and control groups (no treatment, antibiotic prophylaxis, prophylaxis with Proanthocyanidin). However, most clinical trials used an association of different substances commingled with D mannose, dosages and regimens of D mannose were different. For this reason, the evidence of the efficacy of D mannose remains low.

Abstract Background: Acinetobacter species have emerged as important cause of nosocomial infections like pneumonia and urinary tract infections. Acinetobacter species are known to be highly resistant to commonly used antimicrobial agents. SinceAcinetobacter species are ubiquitous and have tremendous colonizing capacity, it is difficult to explain the role of Acinetobacter acquisition in the ICU and medical wards. The objective of this study was to determine the frequency of urinary tract infection (UTI) caused by different Acinetobacter species in hospitalized patients and in the community and to analyze their antimicrobial susceptibility pattern. Materials and Methods: This is a retrospective analysisfrom January 2016 to December 2017. Urine samples collected in appropriate sterile manner were screened for polymorphonuclear leucocytes and bacteria by routine microscopic examination. This was followed by plating on MacConkey's agar and Blood agar. Isolated Acinetobacter strains which are oxidase negative and non-lactose fermenters from MacConkey's agar were identified with Matrix assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF MS) to confirm the TM identification. Antibiotic susceptibility was performed by VitekCompact™ 2 (Biomeuriux, France) as per CLSI standards establishing MIC (Minimum Inhibitory Concentration). Results: Of the 429 isolates of Acinetobacterspecies from urinary tract, Acinetobacterbaumannii complex (78%) found to be the most common species followed by Acinetobacterjunii(10%) and Acinetobacterbaumannii(8%). Of the 334 (78%) isolates of Acinetobacterbaumannii complex from urinary tract, 73 (21.85%) isolates were resistant with doripenem, 62 (18.56%) with imipenem and 59 (17.66%) were resistant with meropenem with MIC values >=8 μg/ml. The rest of the isolates like Acinetobacterjunii, Acinetobacterjohnsonii, andAcinetobacterlwoffiiare found to be more sensitive with carbapenems with lower MIC values. Discussion: The treatment of multidrug-resistant bacteria in hospitalized patients continues to be a challenge for the clinician's in routine practice. Acinetobacter baumannii complex has proven to be an important pathogen in health care associated infections with significant mortality and morbidity. The drug resistant nature of the pathogen and its unpredictable susceptibility patterns make empirical and therapeutic decisions even more difficult. Conclusion: A. baumanniiis an important opportunistic agent of nosocomial UTI, especially in patients with longer hospitalization, antibiotic exposure, urinary catheterization and decreased immunity. High antimicrobial resistance and patient co-morbidities limit therapeutic choices. Hence, alternative therapeutic options are urgently needed to treat a patient with A. baumanniiinfection.
