Long-term conjunctival infections are challenging for the outpatient ophthalmologist. This is due to significant changes in microflora towards resistant gram-negative bacteria. Long-term conjunctival infections are challenging for the outpatient ophthalmologist. This is due to a significant change in microflora towards resistant gram-negative bacteria. The above studies are based on microbial associations, which are the causes of inflammatory processes, conjunctiva and cornea.Purpose: to increase the effectiveness of the diagnosis and treatment of chronic specific inflammatory diseases of the organs of vision.Patients and methods. The study was conducted in patients with chlamydial infection (n = 589) and included chronic conjunctival infections lasting more than 4 weeks, follow-up of patients with partners, family members for 3 or more years. Results. The study was carried out in patients with chlamydial infection (n = 589) and with chronic infectious diseases that lasted more than 4 weeks, following patients and family members for 3 or more years. During this period, we performed more than 3 studies for each patient — for diagnostic laboratory studies and 2 consecutive controls 1 and 2 months after treatment, mixed infection was detected in 256 people (10 %), the proportion of women was 20–30 years is 67 %, men — 51 %. In 27 % of cases, communities of Ch. trachomatis and Ureaplasma parvum as leading causative agents of the eye infections.Conclusions. Chlamydia is most often found together with Ureaplasma parvum (27 % of cases among mixed infections). Treatment of various forms of chlаmidia infection is carried out with the help of “Floxal” (0.3 % ofloxacin — drops and ointment).

In recent decades, the etiological structure of infectious complications in surgery has remained almost unchanged. The aim of this study is to identify the leading pathogens of odontogenic infectious and inflammatory diseases of the maxillofacial area in patients. Materials and methods. The study involved 137 patients with odontogenic infectious and inflammatory diseases of the maxillofacial area. The final species identification of microorganisms was performed according to the generally accepted method. Results. 117 clinical strains of microorganisms were isolated from patients and identified. It was found the most common causative agents of odontogenic infectious and inflammatory diseases of the maxillofacial area in patients were gram-positive cocci. It should be noted that the vast majority of isolates were members of the genus Staphylococcus. Gram-negative microorganisms were detected in patients much less frequently (31.6%) compared with gram-positive. In 5.1% of case, C. albicans acted as the dominant pathogen in the material taken from patients with purulent diseases. It was found out that during the development of the abscess, the microbiota were more diverse, but the percentage of pathogens differed significantly with the selection of S. aureus, A. baumannii and E. faecalis as the main ones. In turn, with the aggravation of the infectious process and the development of phlegmon and mediastinitis in patients, a decrease in the spectrum of microorganisms in the studied materials was observed, along with an increase in their percentages. Conclusions. The etiological structure of microbiota of odontogenic infectious-inflammatory diseases of the maxillofacial area is predominantly represented by opportunistic microorganisms of the genera Staphylococcus, Enterococcus, Acinetobacter and Pseudomonas. In general, gram-positive cocci and non-fermenting gram-negative bacteria are the dominant causative agents of odontogenic infectious-inflammatory diseases of the maxillofacial area in most surgical patients.

Medical, social and economic relevance of inflammatory diseases of the woman's reproductive organs requires a very careful attitude to the diagnosis and treatment of this pathology. The number of patients with genital infections and inflammatory diseases of the pelvic organs can takes the first place in structure of gynecological morbidity, and is 60.4-65.0%, and this fact is not unique to Russia, but all over the world. Incidence rate of inflammatory diseases of the pelvic organs in the first decade of the twenty-first century is increased at 1.4 times in patients who are from 18 to 24 years old and at 1.8 times in patients aged 25-29 years. At the same time, the cost of diagnosis and treatment has increased, reaching 50-60% of the total cost of providing gynecological care for population. The inflammatory diseases of pelvic organs are a collective concept. It includes of various nosological forms. There are numerous contradictions in the views on diagnostic approaches and treatment tactics, the nature of screening and control over the long-term results of treatment, the etiological and pathogenetic significance of various microorganisms found in the genital tract in patients with inflammatory diseases of the pelvic organs. Currently, there are many opinions among specialists about diagnostic approaches and treatment tactics, the type of screening and monitoring the long-term results of treatment, the etiological and pathogenetic role of various microorganisms which can be found in the genital tract in patients with inflammatory diseases. This review presents the results of a modern approach to the diagnosis, management and rehabilitation of patients with inflammatory diseases of the pelvic organs.

Abstract Objective To understand the pattern and types of healthcare associated infections (HAI) at our healthcare facility, and to determine the common causative agents and their antibiotic susceptibility profile. Methods One hundred consecutive patients diagnosed with HAI were enrolled and monitored; the causative organisms isolated on culture were recorded and their sensitivity profile was generated. Results Of the 100 patients diagnosed with HAI (mean age ± SD being 42 ± 17 years), there were a total of 110 hospital acquired infections with 10 patients having two infections each. Out of 100 patients with HAI, 69 patients had ventilator associated pneumonia (VAP), 21 patients had catheter associated urinary tract infection (CAUTI) patients, and 20 patients had central line associated bloodstream infection (CLABSI). There were 10 patients with both VAP and CAUTI. All of the HAIs were device associated. A total of 76 pathogens were isolated on culture. No organism was isolated in 40 HAI. Majority (94.7%) of the organisms isolated from HAIs were gram-negative bacteria and all were multidrug resistant. Seventy-seven of the enrolled patients expired while 23 were discharged from the hospital Conclusions Our study demonstrated that HAIs occur in patients of all age groups; younger patients are not spared. Majority of the HAIs were caused by multidrug resistant gram-negative bacteria and were associated with high patient mortality. Acinetobacter species was the most common organism associated with HAI.

ABSTRACTA colistin-glycopeptide combination (CGC) has been shownin vitroto be synergistic against multidrug-resistant Gram-negative bacteria (MDR GNB), especiallyAcinetobacter baumannii, and to prevent further resistance. However, clinical data are lacking. We carried out a retrospective multicenter study of patients hospitalized in intensive care units (ICUs) who received colistin for GNB infection over a 1-year period, to assess the rates of nephrotoxicity and 30-day mortality after treatment onset among patients treated with and without CGC for ≥48 h. Of the 184 patients treated with colistin, GNB infection was documented for 166. The main causative agents were MDRA. baumannii(59.6%), MDRPseudomonas aeruginosa(18.7%), and carbapenem-resistantKlebsiella pneumoniae(14.5%); in 16.9% of patients, a Gram-positive bacterium (GPB) coinfection was documented. Overall, 68 patients (40.9%) received CGC. Comparison of patients treated with and without CGC showed significant differences for respiratory failure (39.7% versus 58.2%), ventilator-associated pneumonia (54.4% versus 71.4%), MDRA. baumanniiinfection (70.6% versus 52%), and GPB coinfection (41.2% versus 0%); there were no differences for nephrotoxicity (11.8% versus 13.3%) and 30-day mortality (33.8% versus 29.6%). Cox analysis performed on patients who survived for ≥5 days after treatment onset showed that the Charlson index (hazard ratio [HR], 1.26; 95% confidence interval [CI], 1.01 to 1.44;P= 0.001) and MDRA. baumanniiinfection (HR, 2.51; 95% CI, 1.23 to 5.12;P= 0.01) were independent predictors of 30-day mortality, whereas receiving CGC for ≥5 days was a protective factor (HR, 0.42; 95% CI, 0.19 to 0.93;P= 0.03). We found that CGC was not associated with higher nephrotoxicity and was a protective factor for mortality if administered for ≥5 days.

ABSTRACTReports of outbreaks concerning carbapenemase-producing Gram-negative bacteria in which the main source of transmission is the hospital environment are increasing. This study describes the results of environmental sampling in a protracted polyspecies metallo-beta-lactamase GIM-1 outbreak driven by plasmids and bacterial clones ofEnterobacter cloacaeandPseudomonas aeruginosain a tertiary care center. Environmental sampling targeting wet locations (especially sinks) was carried out on a surgical intensive care unit and on a medical ward on several occasions in 2012 and 2013. We were able to demonstrate 43blaGIM-1-carrying bacteria (mainly nonfermenters but alsoEnterobacteriaceae) that were either related or unrelated to clinical strains in 30 sinks and one hair washbasin. GIM-1 was found in 12 different species, some of which are described here as carriers of GIM-1. Forty out of 43 bacteria displayed resistance to carbapenems and, in addition, to various non-beta-lactam antibiotics. Colistin resistance was observed in twoE. cloacaeisolates with MICs above 256 mg/liter. TheblaGIM-1gene was harbored in 12 different class 1 integrons, some without the typical 3′ end. TheblaGIM-1gene was localized on plasmids in five isolates.In vitroplasmid transfer by conjugation was successful in one isolate. The environment, with putatively multispecies biofilms, seems to be an important biological niche for multidrug-resistant bacteria and resistance genes. Biofilms may serve as a “melting pot” for horizontal gene transfer, for dissemination into new species, and as a reservoir to propagate future hospital outbreaks.IMPORTANCEIn Gram-negative bacteria, resistance to the clinically relevant broad-spectrum carbapenem antibiotics is a major public health concern. Major reservoirs for these resistant organisms are not only the gastrointestinal tracts of animals and humans but also the (hospital) environment. Due to the difficulty in eradicating biofilm formation in the latter, a sustained dissemination of multidrug-resistant bacteria from the environment can occur. In addition, horizontal transfer of resistance genes on mobile genetic elements within biofilms adds to the total “resistance gene pool” in the environment. To gain insight into the transmission pathways of a rare and locally restricted carbapenemases resistance gene (blaGIM-1), we analyzed the genetic background of theblaGIM-1gene in environmental bacteria during a long-term polyspecies outbreak in a German hospital.

Metal and metal oxide nanoparticles (NPs) are promising antibacterial agents. They have a broad antimicrobial activity against both Gram-positive and Gram-negative bacteria, viruses, and protozoans. The use of NPs reduces the possibility of the microbial resistance development. This review briefly shows the general mechanisms and the main factors of antibacterial activity of NPs. In this article, a comprehensive review of the recent researches in the field of new antimicrobial agents with superior long-term bactericidal activity and low toxicity is provided. The review gives the examples of synthesis of double and triple nanocomposites based on following oxides: CuO, ZnO, Fe3O4, Ag2O, MnO2, etc. including metal and nonmetal doped nanocomposites (for example with Ag, Ce, Cr, Mn, Nd, Co, Sn, Fe, N, F, etc.). Compared with bactericidal action of individual oxides, the nanocomposites demonstrate superior antibacterial activity and have synergistic effects. For example, the antimicrobial activity of ZnO against both Gram-positive and Gram-negative bacteria was increased by -100% by formation of triple nanocomposites ZnO—MnO2—Cu2O or ZnO—Ag2O—Ag2S. Similar effect was showed for Ce-doped ZnO and Zn-doped CuO. The present article also provides the examples of nanocomposites containing NPs and organic (chitosan, cellulose, polyvinylpyrrolidone, biopolymers, etc.) or inorganic materials with special structure (graphene oxide, TiO2 nanotubes, silica) which demonstrate controlled release and longterm antibacterial activity. All of the considered nanocomposites and their combinations have a pronounced long-term antimicrobial effect including against antibiotic-resistant strains. They are able to prevent the formation of microbial biofilms on biotic and abiotic surfaces, have low toxicity to eukaryotic cells, demonstrate anti-inflammatory and woundhealing properties in compositions with polymers (sodium alginate, collagen, polyvinylpyrrolidone, etc.). The use of nanoscale systems can solve several important practical problems at the same time: saving of long-term antimicrobial activities while reducing the number of compounds, creation of new antimicrobial agents with low toxicity and reduced environmental impact, development of new biocidal materials, including new coatings for effective antimicrobial protection of medical devices.
