Introduction: The fight against nosocomial infections, particularly those linked to environmental germs, is one of the priorities of health establishments. Microbiological control of the hospital environment is an essential element of the strategy for the fight against these infections. The aim of this study is to determine the microbial ecology of hospital surfaces and medical devices. Methods: This is a study, which was carried out in the El Idrissi hospital in Kénitra. For the microbiological control of surfaces, we opted for the swab technique: the search for specific germs on flat surfaces and in areas that are difficult to access and not flat. Results: Among the bacteria most frequently responsible for isolated nosocomial infections: Bacillus (28%) and coagulase-negative staphylococci (27%) were predominant, followed by Staphylococcus aureus (19%), Klebsiella pneumoniae (17%), Pseudomonas aeruginosa (5%), Enterobacter cloacae (3%) and Proteus vulgaris (1%).The overall distribution of germs by department showed their predominance in intensive care units (30%), traumatology (11%), emergencies (11%) and in operating rooms (9%). Conclusion: Periodic microbiological controls must be put in place in order to identify any contamination, to carry out preventive actions, procedures and a fundamental approach for the control of infectious risks in the hospital.

Abstract: Infection acquired in the hospital (nosocomial infection) is defined as an infection that does not exist or is in the incubation period at the time of hospital admission and is associated with health care. Nosocomial infection occurs as a result of interaction of several factors, among others, the types of microbes in the hospital environment, nursing actions that allow microbial intervention into the body through the skin and mucous membranes, interactions among patients, hospital workers, equipment and the environment as well as an increase of opportunistic microbial resistance. This study aimed to determine the pattern of aerobic bacteria that were potential to cause nosocomial infections in the delivery room of Prof. Dr. R. D. Kandou Hospital Manado. This was a prospective descriptive study. Samples were obtained from walls, floors, medical equipment, and the air in the delivery room at Prof. Dr. R. D. Kandou Manado. The results showed that of 22 samples, there were several types of bacteria as follows: Bacillus subtillis (40.1%), Enterobacter aerogenes (18.2%), Gram-negative cocci (18.2%), Serratia liquefaciens (13.6%), and Enterobacter cloacae (9.9%). Conclusion: The most common type of aerobic bacteria in the delivery room of Prof. Dr. R. D. Kandou Hospital Manado was Bacillus subtillis. Keywords: delivery room, nosocomial infections, aerobic bacteria Abstrak: Infeksi yang didapat di rumah sakit (nosokomial) didefinisikan sebagai infeksi yang belum ada atau sedang dalam masa inkubasi pada saat masuk rumah sakit dan infeksi yang berkaitan dengan perawatan kesehatan.

The hospital environment, especially medical devices and surfaces, represents a secondary reservoir for pathogens. This work aims to evaluate the microbiological quality of surfaces and medical equipment of controlled environment services (burn unit, operating room, and sterilization service) at a hospital in Meknes (center of Morocco). This study was carried out for three months (September-December of 2017). A total of 63 samples were taken by swabbing technique from different surfaces and medical equipment after bio-cleaning. Identification was performed according to conventional bacteriological methods and by microscopic observation for fungi. The study showed that 68% of the surface was contaminated. The operating room recorded a rate of 93% of contamination (p-value <0.01), 83% for sterilization service, and 47% for burn unit. A percentage of 67% of the isolates were identified as Gram-positive bacteria against 32% Gram-negative bacteria (p-value <0.05). Bacterial identification showed Coagulase-negative Staphylococci (45%), Enterobacter cloacae (14%), Micrococcus sp (10%), Klebsiella pneumoniae, peptostreptococcus sp and Pseudomonas fluorescens (7% for each one), Escherichia coli, and Methicillin-resistant Staphylococcus aureus (5% for each one). These results require corrective action represented by rigorous cleaning and disinfection procedures.

Мета роботи — вивчити резистентність до антибіотиків бактеріальних збудників інфекцій сечових шляхів (ІСШ), виділених у пацієнтів урологічного стаціонару в м. Києві. Матеріали і методи. Досліджено 1612 штамів бактерій, виділених із сечі хворих з ІСШ (цистит, уретрит, пієлонефрит), госпіталізованих в урологічне відділення ДУ «Інститут урології НАМН України» у м. Києві протягом 2016 р. Серед пацієнтів переважали жінки — 1201 (74,5 %). Вік хворих становив від 17 до 74 років. Для збору даних використано медичну документацію лікарні. Мікробіологічні дослідження виконано у лабораторії мікробіології ДУ «Інститут урології НАМН України». Аналізували результати культурального дослідження зразків сечі, зібраних за наявності клінічних ознак ІСШ. Дослідження клінічного матеріалу та інтерпретацію отриманих результатів проводили загальноприйнятими методами. Вивчено чутливість уропатогенів до 31 антибіотика дискодифузійним методом відповідно до рекомендацій Інституту клінічних та лабораторних стандартів США (Clinical and Laboratory Standards Institute (CLSI)). Результати та обговорення. Аналіз мікробного спектра сечі виявив домінування серед уропатогенів штамів Escherichia coli (32,0 %), Enterococcus faecalis (19,5 %), Klebsiella pneumoniae (10,9 %), Staphylococcus epidermidis (8,9 %), S. haemolyticus (6,5 %) та Pseudomonas aeruginosa (6,4 %). Частка Enterococcus faecium, Enterobacter aerogenes і Streptococcus viridans становила відповідно 2,5, 2,2 і 1,6 %, Enterobacter cloacae, Klebsiella oxytoca, Acinetobacter baumannii, Proteus vulgaris та Providencia rettgeri — менше 1,0 %. У більшості випадків (69,7 %) мікроорганізми виділено у монокультурі, у решті випадків — у мікробних асоціа- ціях. Високу резистентність до тестованих антибіотиків виявили штами E. aerogenes (45,1 %), E. cloacae (45,7 %), E. faecium (40,9 %), E. faecalis (40,7 %), E. coli (39,9 %), P. aeruginosa (34,0 %), K. pneumoniae (28,6 %). Найбільш активними до уропатогенів були іміпенем (E. coli — 87,6 %, P. aeruginosa — 75,7 %, E. cloacae — 67,3 %, E. aerogenes — 72,6 %, K. pneumoniae — 93,2 %), меропенем (E. coli — 89,1 %, P. aeruginosa — 76,7 %, K. pneumoniae — 82,6 %), лефлоцин (E. coli — 74,5 %, ентерококи — 78,7 %, P. aeruginosa — 76,7 %, E. cloacae — 73,9 %, E. aerogenes — 80,4 %, K. pneumoniae — 83,5 %), амоксицилін/клавуланат (ентерококи — 84,6 %), фурагін (ентерококи — 82,6 %), цефоперазон (K. pneumoniae — 89,2 %, P. aeruginosa — 73,8 %), цефтріаксон (K. pneumoniae — 80,1 %). Висновки. Антибіотикорезистентність збудників ІСШ — важлива терапевтична проблема. Найбільшою активністю до уропатогенів характеризуються іміпенем, меропенем, лефлоцин, амоксицилін/ клавуланат, фурагін, цефоперазон, цефтріаксон, які можна розглядати як препарат вибору для призначення стартової терапії ІСШ. Необхідно здійснювати постійний моніторинг за резистентністю до дії антибіотиків. Політику використання антибіотиків у кожному стаціонарі слід визначати залежно від локальних даних щодо резистентності до протимікробних препаратів.

ABSTRACTObjective: Nosocomial infections or Hospital acquired infection (HAI) are one of the major threats to hospitalized patients as well as for the hospitalassociated personnel. In last few years there is a gross change in causative agents, new organisms have come out with great threat to hospitals as theypossess antibiotic resistance property e.g. production of biofilm, production of enzymes such as β- lactamases. Among many organisms, Acinetobacterbaumannii has emerged as a potent nosocomial pathogen. Our objective of this study was to find the burden of Acinetobacter baumannii infectionswhich are associated as nosocomial infections and to determine the drug of choice for an effective treatment.Methods: Clinical specimens were collected from patients of different unit of the hospital by maintaining universal precautions and standardmicrobiological protocols. All the respective specimens were cultured in respective culture medium i.e. MacConkey agar, blood agar, chocolate agar,cysteine lactose electrolyte deficient (CLED) agar and, fluid thioglycolate (TG) medium at 37˚C for 24-48 hours. After incubation of 24-48 hours cultureplates were examined for bacterial growth and identification and antibiotic sensitivity test was made by Vitek2 compact.Result: The study was conducted at the department of microbiology from January 2016 to April 2016. A total of 2582 specimens were collected andprocessed for identification and sensitivity testing. Specimens of all age group (2 days- 93 years) and both sexes were processed for identificationof A. baumannii and antibiotic sensitivity testing. A total of 119 isolates (4.60%) of A. baumannii were obtained from 2582 clinical specimens. Themost common infection A. baumannii was found as lower respiratory tract infection (89.07%) followed by abscess (6.72%), septicaemia (2.52%),urinary tract infections (0.84%), and soft tissue infections (0.84%). The maximum sensitivity of A. baumannii isolates were seen to Colistin (CL) (119,100%), followed by Tigecycline (TGC) (63, 52.94%) and Minocycline (MIN) (27, 22.69%). The maximum resistant was observed for Imipenem (IMI),Aztreonam (AZT) and Ticarcillin- clavulanic acid (TIC) (119, 100%).Conclusion: The Gram- negative coccobacillus, Acinetobacter baumannii poses a formidable threat to patients. It has emerged as a superbug inhospital environment particularly in ICU units. The chances of A. baumannii infections increase in the presence of iatrogenic factors like inadequatelong- term antibiotic therapy and new interventions in a medical facility. To control the burden of Acinetobacter infections new therapies suchas combine therapy must be obtained and followed with proper dose as recommend by physicians; along with awareness of the importance ofthis infection should be implicated. Proper sanitation, good housekeeping, sterilization of equipment, hand hygiene, water purification, isolationprocedures and maintaining of the hospital environment, use of infection control practices are some of the measures to control the transmission ofAcinetobacter spp. among hospital personnel.Keywords: Acinetobacter baumannii, Biofilm, β-lactamases, Hospital acquired infection.

Water is the main stimulus for the development of microorganisms, and its flow has an important role in the spreading of contaminants. In hospitals, the water distribution system requires special attention since it can be a source of pathogens, including those in the form of biofilms often correlated with resistance of microorganisms to various treatments. In this paper, information relevant to cases of nosocomial infections involving water circuits as a source of contaminants is compiled, with emphasis on the importance of microbiological control strategies to prevent the installation, spreading and growth of microorganisms in hospitals. An overview of the worldwide situation is provided, with emphasis on Brazilian hospitals. Different approaches normally used to control the occurrence of nosocomial infections due to waterborne contaminants are analyzed, and the use of the polysaccharide chitosan for this specific application is briefly discussed.

Species Specific

The activity of beta-lactam antibiotics (oxacillin, cloxacillin, cephalotin), vancomycin, gentamicin and rifampicin applied in vitro individually and in combination against 37 nosocomial methicillin-resistant strains of coagulase-negative staphylococci (CNS) was assessed to demonstrate the heterogeneity of this group of bacteria and estimate the chance of the efficacy of such therapy. The strains belonged to four species: Staphylococcus epidermidis, Staphylococcus haemolyticus, Staphylococcus cohnii, Staphylococcus hominis. They originated from a hospital environment and from the skin of medical staff of the intensive care unit of a paediatric ward at a university hospital. All strains were methicillin-resistant, according to CLSI standards, but individual strains differed in MIC(ox) values. Susceptibility to other tested antibiotics was also characteristic for the species. The increased susceptibility to antibiotics in combinations, tested by calculating the fractional inhibitory concentration (FIC) index, concerned 26 out of 37 investigated strains and it was a feature of a particular species. Combinations of vancomycin and cephalotin against S. epidermidis and oxacillin with vancomycin were significant, as well as cephalotin and rifampicin in growth inhibition of multiresistant S. haemolyticus strains.
