The genus Bordetella contains several pathogenic species generally associated with upper respiratory tract infections in warm-blooded animals. Bordetella pertussis is the etiologic agent of whooping cough. Whooping cough is presently one of the ten most common causes of death from infectious diseases and reported by the World Health Organisation (WHO) to cause 50 million cases and 350000 deaths worldwide per year, mainly among unvaccinated individuals in poor countries. The term proteome, in analogy to the term genome, was coined to describe the complete set of proteins that an organism has produced under a defined set of conditions. Proteomics has been used to identify novel bacterial vaccine candidates against several human pathogens. Fueled by growing DNA sequence information, the analysis of the proteome becomes a valuable and useful tool for antigen discovery. Much of information about immunogenic component can be derived from proteomics coupled to Western blotting, namely immunoproteomics. v In the present study, we report first immunoproteomics analysis to identify candidate antigens of B. pertussis for vaccine development. Different sera from mice, which were immunized or challenged with B. pertussis, were analyzed for reactivity by Western blot against whole cell extracts of B. pertussis Tohama and Saadet strains separated by 2-DE. We identified 15 immunogenic proteins of Bordetella pertussis as a total (60 kDa chaperonin, heat shock protein, serum resistance protein, putative substrate-CoA ligase, ATP-dependent protease, preprotein translocase secA subunit, S-adenosylmethionine synthetase, elongation factor Tu, RNA polymerase alpha subunit, ketol-acid reductoisomerase, pertactin, lysyl-tRNA synthetase, serum resistance protein, carbamoyl-phosphate synthase large chain, 30S ribosomal protein S1 subunit), 6 of which being identified as immunogenic in a pathogenic microbe (ATP-dependent protease, carbamoylphosphate synthase large chain, lysyl-tRNA synthetase, putative chromosome partition protein, preprotein translocase secA subunit, 30S ribosomal protein S1 subunit) and 5 identified as immunogenic for Bordetella pertussis (RNA polymerase alpha subunit, S-adenosylmethionine synthatase, putative substrate-CoA ligase, elongation factor Tu, ketol-acid reductoisomerase) for the first time.

Pertussis is a contagious disease which is commonly seen among infants and children and caused by a human pathogen known as Bordetella pertussis. There are currently two vaccine types available against the disease; whole-cell (wP) and acellular pertussis (aP) vaccines. Due to the side effects of wP vaccine, aP vaccines are commonly preferred for vaccination. Despite high vaccination coverage, high incidence rates among adolescents and adults have been reported causing the resurgence of pertussis to be the f...
Development of an experimental recombinant vaccine formulation composed of LKTA from Mannheimia Haemolytica A1 and P31 and LPPB from Histophilus Somni 8025 against Hovine Respiratory Disease
Türkmen, Nazlı Hilal; Özcengiz, Gülay; Department of Molecular Biology and Genetics (2020-9)
Two major bacterial pathogens of Bovine Respiratory Disease (BRD), Mannheimia haemolytica and Histophilus somni are Gram-negative, opportunistic bacteria that live in upper respiratory tracts of ruminants commensally. The one of the most important virulence factor of M. haemolytica, leukotoxin, is responsible for lung colonization and establishment of infection. On the other hand, H. somni OMPs have a significant contribution to the pathogenicity of the organism. As the disease results in a destroyed animal...
Ultra-fast quantitation of voriconazole in human plasma by coated blade spray mass spectrometry
Tascon, Marcos; Gomez-Rios, German Augusto; Reyes-Garces, Nathaly; Poole, Justen; Boyacı, Ezel; Pawliszyn, Janusz (2017-09-10)
Voriconazole is a triazole broad-spectrum antifungal medication often used to treat fungal infections caused by Aspergillus and Fusarium species. One of the main challenges associated with the implementation of this medication is its narrow therapeutic concentration range, demonstrating toxicity at concentrations above 6 mu g/mL and limited efficacy at concentrations below 2 mu g/mL. As a result, methodologies which permit the rapid and accurate quantitation of voriconazole in patients are highly desirable....
Analysis of cellulase and polyphenol oxidase production by southern pine beetle associated fungi
Valiev, Abduvali; Ögel, Zümrüt Begüm; Klepzig, Kier D. (Springer Science and Business Media LLC, 2009-09-01)
In this study, the production of extracellular enzymes by fungi associated with southern pine beetle was investigated for the first time. Cellulase and polyphenol oxidase production were analyzed for three beetle associated fungi. Only the mutualistic symbiont Entomocorticium sp. A was found to produce cellulases and polyphenol oxidase. In time course analyses of cellulase production in batch cultures, Entomocorticium sp. A showed maximum activity of 0.109 U/ml and 0.141 U/ml for total cellulase and endoglu...
The effects of CGAS-STING-TBK1 pathway and NKT cell-activating ligand alpha-galactosylceramide on LEISHMANIA MAJOR infection and protection
Dünüroğlu, Emre; Gürsel, Mayda; Department of Molecular Biology and Genetics (2022-2-8)
Leishmaniasis is a multi-faceted group of diseases caused by various species of Leishmania protozoa. Depending on the infecting Leishmania species, the disease manifests as recurrent cutaneous, mucocutaneous or visceral leishmaniasis all of which can be devastating for infected individuals. Lack of a protective vaccine and the rise of drug resistances in Leishmania spp. prompted us to explore preventative vaccine candidates and novel drugs against Leishmania major. In the first part of this thesis, we evalu...
