Abstract:

<I>Moraxella catarrhalis</I> is a gram-negative diplococcus which until recently was thought to be a harmless commensal. Increasing awareness has established the pathogenic nature of this organism and it is now recognised as a major cause of otitis media in children, exacerbations of chronic bronchitis in elderly patients and an occasional cause of invasive disease. <I>M. catarrhalis</I> is spread nosocomially especially in respiratory wards containing elderly patients. This study evaluated four methods for typing nosocomially spread isolates:- immunoblotting with normal human serum (NHS), and

Abstract:

Moraxella (Branhamella) catarrhalis is the third-most-frequently isolated microorganism associated with acute exacerbations of chronic bronchitis in patients during their stay at the Mountain Home VA Medical Center (MHVAMC). In order to develop a practical, epidemiologically-meaningful typing method for M. (B.) catarrhalis, we tested two methods based on analysis of chromosomal DNA for typeability, reproducibility, and ability to differentiate between unrelated strains (discriminatory power, D). M. (B.) catarrhalis isolants from MHVAMC from 7/1/87-6/30/88 were grown overnight i

Abstract:

The enzyme, aspartate transcarbamoylase (ATCase) from Moraxella (Branhamella) catarrhalis, has been purified. The holoenzyme has a molecular mass of approximately 510kDa, harbors predominantly positive charges and is hydrophobic in nature. The holoenzyme possesses two subunits, a smaller one of 40 kDa and a larger one of 45 kDa. A third polypeptide has been found to contribute to the overall enzymatic activity, having an approximate mass of 55 kDa. The ATCase purification included the generation of cell-free extract, streptomycin sulfate cut, 60 °C heat step, ammonium sulfate cut, dialysis an

Abstract:

Bacterial aspartate transcarbamoylases (ATCase's) are divided into three classes that correspond to taxonomic relationships within the bacteria. The opportunistic pathogen Moraxeila catarrhalis has undergone several reclassifications based on traditional microbiological criteria. The previously uncharacterized ATCase from M. catarrhalis was purified to homogeneity and its chemical properties characterized. The ATCase from M. catarrhalis is a class C ATCase with an apparent molecular mass of 480-520 kDa. The M. catarrhalis ATCase is a dodecomer composed of six 35 kDa polypeptides and six 45 kDa

This thesis reports the characterisation of a novel outer membrane protein (OMP) from M. catarrhalis, designated M35, with a molecular mass of 36.1 kDa. This protein is structurally homologous to classic Gram-negative porins, such as OMP C from E. coli and OMP K36 from K. pneumoniae, with a predicted structure of 8 surface loops connecting 16 antiparallel -sheets. Comparison of the DNA sequences of the M35 genes from 18 diverse clinical isolates showed that the gene was highly conserved (99.6-100 % of nucleotides) with only one isolate (ID78LN266) having base variations that resulted in amino

Abstract:

The Gram-negative bacterium, Moraxella ca tarrhalis, is an opportunistic human pathogen that colonises the nasopharynx of healthy individuals. The disease most often associated with this organism is otitis media in children, though it is increasingly implicated in lower respiratory tract infections and even some cases of meningitis, endocarditis and bacteraemia. The most commonly quoted sites of colonisation and infection are the nasopharynx, tympanic cavity and lower respiratory tract. The different microenvironments found at these infection sites suggest a range of conditions in which the ba

The hyperplasia of lymph node cells was investigated by examining the growth characteristics of freshly explanted lymph node cells from AHV-1 infected rabbits.

Abstract:

Le sérotype 8 du virus de la fièvre catarrhale ovine (FCO) avait eu un fort impact économique sur la filière bovine lors de l’épizootie entre 2006 et 2009 en France. Les travaux établis au cours de cette thèse visaient à évaluer l’impact financier de la circulation de la FCO après sa réémergence en 2015, et à apporter des éclairages nouveaux sur la dynamique des Culicoides, et sur les mesures de surveillance et de lutte. Par la récolte et l’analyse de données, nous avons pu calculer le coût des mesures de surveillance de septembre 2015 à décembre 2016 (14,6 M€ HT). Grâce à l’analyse des donnée

La Fièvre Catarrhale Ovine est due à un virus affectant les ruminants. Les vaccins actuellement disponibles (atténués ou inactivés) ne permettent pas, ou peu, de protection croisée entre les 24 sérotypes identifiés. Notre travail de thèse a consisté à développer chez le mouton des vaccins recombinants dérivés d’adénovirus canin de type 2 capables d’induire une protection contre un maximum de sérotypes<br>Bluetongue is a viral disease that affects Ruminants.

Abstract:

Ovine herpesvirus 2 (OvHV-2) is the causative agent of sheep-associated malignant catarrhal fever (MCF) in susceptible ruminants. Through an unknown mechanism, presence of the virus leads to proliferation of NK-like T cells that are not targetrestricted by the MHC class molecules. These host cells cause the symptoms found in MCF; fever, swollen lymph nodes, and necrotic lesions of the nasal, conjunctival, and oral mucosa, which usually leads to death of the host. MicroRNAs (miRNAs) are ~22 nt RNA molecules expressed by eukaryotes and viruses that regulate genes post-transcriptionally. Viral mi
