The results of own epidemiological and clinical studies are presented in comparison with literature data. Cyclic recurrence of hRSv circulation was revealed. The clinical and epidemiological characteristics of hRSv and hMpv infections were compared. The leading role of the hRSv in ARVI in children and the importance of hMpv as an etiological agent of respiratory infection in adults are shown. Significance of both viruses as the agents of the lower respiratory tract infections is emphasized. The factors contributing to the prevalence of the hRSv in children with ARI are analyzed. Prevention measures for these infections are considered.","PeriodicalId":24020,"journal":{"name":"Zhurnal mikrobiologii, epidemiologii, i immunobiologii","volume":"13 1","pages":"95-105"},"PeriodicalIF":0.0,"publicationDate":"2017-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90465143","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}

Norovirus infection (NVI) epidemiological characteristics evaluation in Moscow at municipal and district levels. Materials and methods. A retrospective analysis of NVI incidence rate was conducted according to the 2009 - 2016 state statistical reporting forms data. Results. In 2009 - 2016 NVI incidence rate has a trend to increase in Moscow, either at municipal and district levels. NVI cases were registered among children mostly (78% in the SEAD of Moscow, 80% in Moscow and 81% in Russia), at the same time adults proportion of NVI incidence rate increased significantly (up to 42,7% in Moscow and 13,9% in the Russian Federation) by 2016. The morbidity dynamics in different child population age groups was effected by the outbreaks cases. Totally in 2011 - 2016 33 outbreaks were registered in Moscow (24,3% from all acute diarrheal infection outbreaks in Moscow for the same period), where 64,3% with nonpercutaneous channel of infection and 35,7% alimentary. Outbreaks were more often recorded in children’s organized collectivity (69,7%). Conclusion. Nowadays in Moscow there is an NVI incidence increase trend is evidenced, with an increase of the adult population proportion in morbidity structure. At this stage, main contribution to group morbidity was made by children 7 - 14 and 15 - 17 years old. One of the reasons for the NVI incidence rate growth in Moscow (2016) could possibly be the lack of effective prevention measures. Actually, specific NVI diagnostics provided only in outbreaks, due to the lack of routine diagnostic tools. The main reason for the NVI group morbidity effective disease area formation is still sanitary and anti-epidemic regime violation at sites and facilities.","PeriodicalId":24020,"journal":{"name":"Zhurnal mikrobiologii, epidemiologii, i immunobiologii","volume":"2 1","pages":"32-37"},"PeriodicalIF":0.0,"publicationDate":"2017-12-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85196175","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}

Rotavirus genotyping was carried out using multiplex PCR and partial sequencing of VP4 and VP7 genes. Results. RVI morbidity in Nizhny Novgorod was shown to be at a moderate level when specific prophylaxis was not applied, multi-year dynamics for morbidity reflects the all-Russian state. 2015 - 2016 were characterized by intensification of the epidemic process in age groups of organized children (3 - 6 and 7 - 14) and adults.

Fused sequences of P. aeruginosa genes oprF, oprl and deleted form of toxA were cloned in plasmids for the expression in Escherichia coli.

Recombinant proteins were administered to mice intraperitonealiy twice with a 2 week interval to evaluate protective properties. Virulent culture of P. aeruginosa strain PA103 was injected into the animals intraperitonealiy 2 weeks after the immunization course as experimental challenge.

AOprF-AOprl consisted of C-terminal region (192 - 342 amino acids) OprF and deletion variant of Oprl protein; 3. OprF-aTox-ΔOprI included full sequence of OprF protein, sequence of nontoxic variant of exotoxin A (without 106 C-terminal amino acids) and deletion variant of Oprl protein. Fused recombinant proteins OprF-AOprl and OprF-aTox-ΔOprI at immunization doses of 25 and 50 pg for the first and second protein, respectively, were shown to have the best protective properties.

Detection of the amplification results was carried out in horizontal electrophoresis in 1.5% agarose gel. Results. The developed method of gene diagnostics was established to allow detection of DNA of toxi­ genic C. diphtheriae strains of 2 biovars, as well as DNA of non-toxigenic tox-gene bearing strains (NTTB) of C. diphtheriae mitis biovar with mechanisms of lack of expression of diphtheria toxin gene due to the presence of deletion or mobile genetic IS element in the tox gene. Non-toxigenic tox-gene bearing C. diphtheriae strain with the mechanism of lack of diphtheria toxin gene expres­ sion due to the presence oftransposon in the tox gene are identified as non-toxigenic.
