[Diagnostic role of different immunologic methods for laboratory diagnostics of legionellosis].

The aim of the study was a comparative analysis of diagnostic value of different laboratoty methods conducted on the basis of results of examination of patients during Legionnaires' disease outbreak in town Verkhnyaya Pyshma. Retrospective analysis of laboratory data from 74 patients with diagnosis of Legionnaires' disease was performed. Complex of laboratory methods was used (polymerase chain reaction (PCR), enzyme immunoassay (EIA), immunochromatography). In group of patients with Legionnaires' disease, the highest proportion of positive results (73%) was obtained by the EIA determining total specific antibodies in urine. Determination of antigen in urine by immunochromatographic express-test yielded 52% of positive results. PCR testing of blood specimens yielded positive results in 65% of samples but was low specific, due to that in 19% of patients from control group false-positive results were obtained. Testing of 3 autopsy samples showed that all specimens contained DNA of the causative agent. Performed analysis allowed to recommend complex use of immunochromatographic express-test of antigen detection and identification of total specific antibodies by EIA during mass people examination.

[Experience of information sharing between local healthcare management and regional Administration of Federal Service for Surveillance for Protection of Consumers Rights and Human Welfare in Sverdlovsk region during outbreak of Legionnaires' disease in town Verkhnyaya Pyshma in July-August 2007].

Issues of reliability, uniformity, and timeliness of reporting and sharing of information during outbreaks of infectious diseases are basic for establishment of tactics and strategy of organizational, antiepidemic, and clinical measures. Analysis of experience in sharing of information between medical care organization service and services ensuring sanitary-epidemiological welfare of population during outbreak of Legionnaires' disease in town Verkhnyaya Pyshma in July-August 2007 was performed in the article.

[Microflora formation in the newborn in maternity hospitals and neonatal abnormality units].

The basic sources of pyoseptic infection pathogens are infected and colonized neonatal infants in maternity hospitals. Microbiological monitoring revealed the specific features of biocenosis formation in the newborn in the "Mother and Baby" units, resuscitative departments (RD), intensive care units, and neonatal abnormality departments (NAD). Irrespective of the conditions of hospital stay, methicillin-resistant S. epidermis (MRSE) and Enterococcus faecium were prevalent in the neonatal microbial landscape. Colonization with the normal flora in the newborn actively treated with antibiotics is difficult in RD, at the same time there is a significant infection with the mycotic flora. Broad-spectrum beta-lactamase producing Klebsiela pneumonia strains have received wide acceptance in NAD.
