Bioinspired free-standing nanomembranes (FSNMs) for selective ion transport have been tailored by immobilizing the Omp2a β-barrel membrane protein inside nanoperforations created in flexible poly(lactic acid) (PLA) nanomembranes. Perforated PLA FSNMs have been prepared by spin-coating a 99 : 1 PLA : poly(vinyl alcohol) mixture, and through a phase segregation process nanofeatures with dimension...
Biomedical platforms constructed by immobilizing membrane proteins in matrixes made of synthetic organic polymers is a challenge because the structure and function of these proteins are affected by environmental conditions. In this work, an operative composite that regulates the diffusion of alkali ions has been prepared by functionalizing a supporting matrix made of poly(N-methylpyrrole) (PNMP...
brucella transmission and epidemiology depend on infecting species and biovar. therefore, exact identification of the brucella is important to design correct control and treatment strategies. in this study, we examined presence of other brucellae in isfahan. one hundred twenty brucella isolates were collected and genomic dna was extracted from them. omp2a fragment of all isolates were amplified...
Brucellosis is a worldwide zoonosis causing reproductive failures in livestock. It is shown that although the vaccine can prevent abortion, it does not provide complete protection against infection. So that vaccination of ewes with Rev.1 biotype can be a source of cattle and even human Brucellosis. The aim of this study was to evaluate possibility of Brucella cross-infection in cattle from Bruc...
We present the first report of community-acquired human infections with marine mammal-associated Brucella spp. and describe the identification of these strains in two patients with neurobrucellosis and intracerebral granulomas. The identification of these isolates as marine mammal strains was based on omp2a sequence and amplification of the region flanking bp26.
زمینه و هدف: بروسلوز یکی از مهمترین بیماری‌های مشترک بین انسان و دام است. به دلیل اهمیت بیماری مذکور و تأثیر انواع بیوتیپ های باکتری بروسلا در طراحی استراتژی های کنترل بیماری، ایزوله‌های انسانی و گوسفندی بروسلا ملی تنسیس جهت تعیین بیوتیپ مورد بررسی قرار گرفتند. روش مطالعه: در این بررسی 5 ایزوله بروسلا ملی تنسیس کشت خون انسان و 25 ایزوله کشت جنین گوسفند از...
Two Gram-negative, non-motile, non-spore-forming, coccoid bacteria (strains CCM 4915(T) and CCM 4916), isolated from clinical specimens of the common vole Microtus arvalis during an epizootic in the Czech Republic in 2001, were subjected to a polyphasic taxonomic study. On the basis of 16S rRNA (rrs) and recA gene sequence similarities, both isolates were allocated to the genus Brucella. Affili...
BACKGROUND Brucellosis is an important zoonotic disease caused by different Brucella species and human brucellosis is commonly prevalent in different states of India. Among various Brucella species, B. melitensis is most pathogenic to human and included as category B biothreat which can cause infection through aerosol, cut, wounds in skin and contact with infected animals. The diagnosis of huma...
