Intrinsic resistance genetic mutations, horizontal transfer of mobile structures carrying genes coding for resistance to the antibiotics within the pan-microbial genome are representing the bacterial resistome which is bearing the genetic information regarding the defensive mechanisms developed by micro-organisms to protect themselves against antibiotics. Rice in the resistance of enteric bacteria, pathogens involved in a large number of human infections, to the cephalosporin of last generation and to the fluoroquinolones is a very actual subject in the medical area. Production of beta-lactamases with extended spectrum is the most important enzymatic defence system, developed by micro-organisms, consisting in the inactivation of beta-lactam antibiotics by destroying the beta-lactam ring. Enterobacteria are able to produce beta-lactamases of type TEM, SHV and/or CTX-M. Punctual mutations in nucleotide structure of bla genes, coding for beta-lactamases synthesis, are leading on production of a large diversity of enzymes with enlarged spectrum of activity (ESBL). At the beginning of 90's the first beta-lactamases resistance to clavulanic acid were detected and in our days more then 170 TEM, 120 SVH and 90 CTX-MESBLs are known. Escherichia coli strains are producing, firstly, TEM ESBLs, Klebsiella pneumoniae SHV ESBLs. and both are producing CTX-M type ESBLs, are resistant to the fluoroquinolones due to punctual mutations in nucleotide structure of gyr gene coding for gyrases production, enzymes involved in nucleic acids replication. Resistance to the antibiotics with extended activity is a public health threat due to their capacity of large spreading within bacterial population, when the coding structures are located on mobile genetic structures.

Macrolides are natural products of secondary metabolism of several species of actynomyces; they represent a group of compounds with a lactonic ring of variable dimensions (12-22 atoms of C) that can bind, by means of glycosidic bonds, sacharridic and/or amino-sacharridic structures. Most of the MLS antibiotics are bacteriostatic. Their mechanisms consist in inhibiting protein synthesis. the target being 50 S subunit of the bacterial ribosome, the binding sites being different for the different MLS classes. Erythromycin (E) was introduced in therapy in 1952; quickly, several bacterial genera started developing resistance to E. Strains resistant to E were as well resistant to all macrolides and other antibiotics with different structures--lincosamides and streptogramines B--resistance phenotype called MLSB. The main molecular mechanisms for bacterial resistance to MLS are: (1) Target modification, coded by erm genes (>12 classes). In Gram-positive cocii MLSB resistance, regardless of erm gene, can be: inducible (i MLSB)--when the presence of the inductor AB is necessary for methylation enzyme production; constitutive (c MLSB)--when the methylation enzyme is continuously produced Distinction between iMLSB and cMLSB can be easily appreciated based on the phenotypic expression of bacteria. In streptococci--all MLSB antibiotics can act as methylase inductors. (2) The decrease of AB intracellular concentration by active efflux, coded by mef genes--also called M resistance phenotype, low level resistance (LLR).

Romania reported data to EARSS since 2002 so far. Though the number of participating laboratories increased progressively from 12 to 35, the number of hospitals which reported for EARSS. as the number of strains included in the data base remained steady and relatively low. This issue is related to the particular position of Romania in the European context, in respect of the very low number of blood cultures performed in hospitals. Our paper is presenting the trends of antimicrobial resistance in the indicator strains in the 2002-2008 interval. During the 2002-2008 interval, Romania reported to EARSS a total number of 1276 bacterial strains, distributed by species as follows: 513 S aureus, 369 E. coli, 128 Streptococcus pneumoniae, 127 Enterococcus spp.. 71 Klebsiella pneumoniae, 68 Pseudomonas aeruginosa. Klebsiella pneumoniae and Pseudomonas aeruginosa were reported, according to the EARSS protocol, only for the 2005-2008 interval.

The surveillance methodology was shared annually, the number of participants varying between 12 and 40 hospitals. During 2005-2008 the Reference Laboratory for Nosocomial Infections and Antibiotic Resistance in the \"Cantacusino\" NIRDMI received 1481 bacterial strains, comprising 531 S. aureus, 486 Pseudomonas aeruginosa, 439 enterobacteria and 25 enterococci strains. The resistance percents widely differred for some species, especially regarding the type of hospital unit that sent the strains (ex., Pseudomonas aeruginosa isolated form patients with burns). A great variability was noted concerning the manner in which nominalized hospitals responded to the solicitations in the methodology that was shared. especially regarding participation to a national bank for bacterial strains. Only for 5 out of the 40 hospitals that participated along the 4 years in the sentinel programme the annual comparative evaluations of antibiotic resistance were achieved. for a small number of microorganisms that underwent surveillance (S. aureus, E. coli). Among the strong points of the system we can point out: unity in methodology; working protocols for microbiological investigation given to all the participants; special forms for reporting. Among the weak points, we consider: modification in the number of participant hospitals during the program: unequal participation of hospitals, with unwanted effects on the sample representativity of analysed microbial strains; difficulties in stocking and processing laboratory data. In order to increase the quality of data provided, we consider the following as useful: harmonization of the objectives regarding integrated surveillance of nosocomial infections and antibiotic resistance in hospital environment, correlated with the ECDC demands and recommendations; inclusion in the system of sanitary units that fit the needs of the program fir microbiological identification and investigation of nosocomial infections; intensification of the training activities of persons involved in the program, regardless of the level of responsibility and the acknowledgement of each person's responsibilities in nosocomial infection monitoring; external and internal control implementation in the laboratories: selection of aspects concerning the emergence and spread of antibiotic resistance that come out during surveillance in order to be studied using molecular methods for the emphasizing of mechanisms and causes, in view of implementing measures for prevention and control; evaluation of the necessity for molecular investigation in view of identifying resistant bacterial clones in the hospitals in Romania etc.</p>","PeriodicalId":77026,"journal":{"name":"Bacteriologia, virusologia, parazitologia, epidemiologia (Bucharest, Romania : 1990)","volume":"55 2","pages":"169-77"},"PeriodicalIF":0.0,"publicationDate":"2010-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"29867491","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Seventeen years ago, O'Brien and col. were describing the current degree of the antimicrobial resistance surveillance as follow: \"There are no reliable data in this area--simply fragments of information and anecdotes that we use to draw an overall picture\" (Diagnostic Microbiology and Infectious Diseases, 1992, 15.53S-60S). Ten years later, Morris and Masterton were showing that there were reports underlying the big volume of activity delivered in the field of antimicrobial resistance surveillance during that time, but there were no major changes in respect of the data quality (JAC,. 2002, 49, 7-10). According to the WHO definition, surveillance, as continuous and systematic process of data collection, data analysis and data reporting, is reaching it's scope only if it is able to provide information valuable for action. Though it is by excellence a type of surveillance based on the microbiology laboratory activity, antimicrobial resistance surveillance is not coming to be useful according to the WHO and EUCAST (European Committee for Antimicrobial Susceptibility Testing) acception without using the epidemiology methods in order to make possible the adoption of a clear strategy, starting from the definition of the type of information that we want to obtain. Pending on the scope and taking into account the preexisting premises for setting up a surveillance network, we need to select the appropriate surveillance methods, in respect of data and strains collection and storage, data reporting, appropriate denominators (population categories. admission days, patient days etc.), data stratifying etc. In Romania there are few data on antimicrobial resistance surveillance which could resist to a critical evaluation of representativity, reporting to adequate denominators, stratifying methodologies which would allow to follow trends, comparing data by wards, hospitals, counties, intercomparing data with other countries etc. Contacting the European Antimicrobial Resistance Surveillance System in 2001 was an initial modality to decrease the huge gap existing by that time, but could not remain the unique solution to develop in this direction. On the other hand, participating in the European Antimicrobial Resistance Surveillance System is enforcing the involvement of all implicated professional categories, improving logistic and interdisciplinary collaboration, in order to set up a systematic surveillance.
