ECOLOGICAL ANALYSIS OF OPPORTUNISTIC MICROFLORA IN PNEUMONIA. Actuality: Purulent-inflammatory diseases of the respiratory tract are more often induced (under the influence of different triggers) by endogenous microflora. One of the factors that determine the appropriateness of the choice of antibiotics and, therefore, the beneficial outcome of the disease is the microbial spectrum of causative agents of infection. At the present time, there is increasing information on changes in the composition of human microbiota at various diseases and its role in the pathogenesis of various disorders, including respiratory diseases. Objective: Studying the species composition of the microflora in non-hospital pneumonia and the determination of the participation of different species in the structure of microbiocenosis. Materials and methods: Bacteriological research of various clinical materials from 336 patients with pneumonia is conducted. Microbiological examination included an isolation of pathogens, identification by morphological, cultural and biochemical properties. An ecological analysis of the microflora of clinical material was carried out by studying its structure and functional characteristics using indicators such as the index of constancy, the Berger-Parker domination index. Results and discussion: During the study of micro-ecological indicators of microflora of patients with pneumonia, the distribution of endogenous microorganisms of nasopharynx in the biocenosis of lungs was revealed, which was confirmed by the indices of constancy and the dominance of Berger-Parker. In the etiological spectrum of infectious factors, fungi of the genus Candida and streptococci of viridans group, which had a high colonization level, were prevailed. Microorganisms were isolated in both a monocultural and associative form, which contained two to five species. Combinations of bacteria and fungi of the genus Candida were the most common, which were registered at 80.7 % (152/187). The associations included not only autochthonous bacteria but also non-specific habitats such as K. pneumoniae, P. aeruginosa, E. coli, E. cloacae, E. aerogenes, E. faecalis, E. faecium, P. vulgaris, P. mirabilis, C. xerosis and A. baumonii. Conclusion: The obtained data have shown that the lungs of patients with pneumonia are actively colonized by the representatives of the microflora of the nasopharynx with certain qualitative and quantitative changes of microbiocenosis. This is manifested in the emergence of transient and random opportunistic microorganisms against the background of reduced domination of the autochthonous
At thepresent time there is a great interest in médical researche devoted to investigation the role of cytokines (interleukins) in the pathogenesis of cardiovascular diseases (atherosclerosis, arterial hypertension, ischemic heart disease, etc.), and osteoporosis. The review provides data on the conducted research on the importance of cytokines in the event of these diseases.
Було обстежено 236 хворих на інфекційні захворювання ЛОР-органів у 2010 р. і 347 хворих у 2015. Мікробіологічне дослідження складалося з виділення збудників, ідентифікації їх за морфологічними, культуральними і біохімічними властивостями.У ході дослідження виявлено, що у період з 2010 до 2015 рр. спостерігалася чітка тенденція зростання питомої частки Candida spp. в етіологічній структурі інфекційних захворювань ЛОР-органів. Незмінною залишалася значуща роль S. aureus і S. epidermidis та стрептококів групи viridans, а зменшення їх відносної частки було обумовлене розширенням спектру збудників за рахунок інших опортуністичних мікроорганізмів (ентерококів, ентеробактеру, протея, коринебактерій, кишкової та синьогнійної паличок). S. aureus був представлений значною мірою у всіх ЛОР-органах, стрептококи групи viridans переважали у носоглотці, а S. epidermidis частіше за всіх виділяли з носа. Захворювання були обумовлені у більшості випадків грибково-бактерійними асоціаціями. Частка грибів роду Candida становила 22,9 %, причому 85,8 % штамів, виділених із слизової оболонки зіва (далі – із зіва), і 81,8 % штамів, виділених із зовнішнього вуха, були представлені в асоціаціях із бактеріями.Отримані дані свідчать про необхідність визначення етіологічно значимої флори, яка спричинює захворювання ЛОР-органів і органів дихання, її моніторингу як на рівні конкретного хворого, так і на регіональному і на рівні країни.
16 second trimester fetuses with 22q11.2 deletion syndrome have been examined at anatomic-pathological investigation. Main cardiovascular diseases were ascending aorta hypoplasia with aortic valve stenosis (n = 6; 37.5%), truncus arteriosus (n = 5; 31.25%), tetralogy of Fallot (n = 3; 18.75%) and double-outlet right ventricle (n = 1; 6.25%). Ventricular septal defect was present in 16 cases. Associated aortic arch anomalies included interrupted aortic arch (n = 9; 56.25%), right aortic arch (n = 6; 37.5%), retroesophageal ring (n = 1; 6.25%) and aberrant right subclavian arteria (n = 5; 31.25%). 5 fetuses had left ventricular outflow tract obstructive lesions with interrupted aortic arch of type B combined with aberrant right subclavian arteria.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
