Biofilm formation by the fish pathogen Flavobacterium columnare: a quantitative and qualitative study

Cai, Wenlong (2013-04-30)

The objective of this study was to evaluate the effect that temperature, pH, salinity, hardness and carbohydrates have on biofilm formation by the fish pathogen Flavobacterium columnare. Nineteen F. columnare strains, ...

Biofilm formation, virulence attenuation and comparative genomics of the fish pathogen Flavobacterium columnare

Cai, Wenlong (2018-11-27)

Flavobacterium columnare is an important bacterial fish pathogen that causes great economic losses in aquaculture. In this dissertation I aimed at characterizing part of its life cycle including the transition between ...

Biological control studies of reniform nematode in Alabama cotton crops

Castillo, Juan D. (2012-08-02)

Rotylenchulus reniformis is the most important pathogen of cotton in the southeastern United States. Aldicarb, which is the most used nematicide in cotton production, will be retired from the market in 2018 by the EPA. ...

Community Dynamics of the Phyllosphere Microbiome

Brokaw, Destiny (2022-04-29)

The phyllosphere of a plant creates a complex niche for inhabiting microorganisms in which interactions will occur. The dynamics of the interactions between a foliar plant pathogen, Xanthomonas perforans, and the resident ...

Competition between strains of the bacterial plant pathogen Xylella fastidiosa

Claudio-Soto, Noel (2023-04-24) ETD File Embargoed

Effect of calcium on biofilm development and role of mopB and msrA in virulence of Xylella fastidiosa

Chen, Hongyu (2016-07-27)

Xylella fastidiosa is the causal agent of many diseases on economically important plants. Pierce’s disease of grape (PD) and citrus variegated chlorosis (CVC) are among the most important diseases caused by X. fastidiosa. ...

Fitness strategies of fastidious prokaryotes

Merfa e Silva, Marcus Vinicius (2021-12-01)

Fastidious prokaryotes are slow-growing bacteria that either require specific media to grow or are not able to grow axenically. ‘Candidatus Liberibacter asiaticus’ (CLas) and Xylella fastidiosa are important fastidious ...
