Abstract:

Bacterial keratitis is a serious ophthalmic disease with significant visual morbidity. The aims of this thesis are to investigate (1) the prevalence and type of bacterial virulence factors in the two major species causing keratitis; Staphylococcal aureus and Pseudomonas aeruginosa and (2) the pharmacodynamics and pharmacokinetics of meropenem, a potentially novel antimicrobial for use in keratitis. The prevalence, genetic diversity and clinical relevance of the lukSF-PV gene, encoding the bacterial toxin Panton Valentine Leukocidin, were investigated in S. aureus, isolated from cases of bacter

PURPOSE. CD36 is a Class B scavenger receptor that is constitu- tively expressed in the corneal epithelium and has been impli- cated in many homeostatic functions, including the homeosta- sis of the epidermal barrier. The aim of this study is to determine (1) whether CD36 is required for the maintenance of the corneal epithelial barrier to infection, and (2) whether CD36-deficient mice present with an increased susceptibility to bacterial keratitis. METHODS. The corneas of CD36- /- , TSP1- /- , TLR2- /- , and C57BL/6 WT mice were screened via slit lamp microscopy or ex vivo analysis. The epith

Abstract:

Infectious keratitis is a sight threatening disease which can cause permanent visual loss if not diagnosed and treated at an early stage. It can be caused by different types of microbes which are either commensals or transferred from the environment. To fight against these threats, the ocular surface (OS) has developed innate and adaptive immune mechanisms. Antimicrobial peptides (AMPs) are natural effectors on the OS with actions that range from microbicidal effects to cell signalling. Human beta defensin (hBD) 1-3 and 9, Liver expressed antimicrobial peptide (LEAP) 1 and 2, human cathelicidi

Abstract:

Microbial keratitis is a major cause of avoidable visual impairment worldwide with S. aureus a leading cause of this disease in humans. Recently S. aureus isolated from eye infections have exhibited resistance to many antibiotics with those isolates from more severe infections exhibiting higher rates of antibiotic resistance. New therapies are therefore needed to ensure adequate treatment for these infections. In microbial keratitis the hosts' immune response is responsible for significant disease pathology so development of a therapy which also targets the immune response would be beneficial.

This thesis describes the impact of contact lens-related microbial keratitis in terms of incidence and severity. Disease outcome is defined by visual outcome, costs to the healthcare system, costs to the individual and duration of disease. A successful 12-month surveillance study was conducted of the populations of Australia and New Zealand to detect all cases of contact lens-related microbial keratitis. A random telephone survey of 32,000 households in Australia and 7,500 in New Zealand accurately determined the level of use of various contact lenses in the community. The impact of new c

Abstract:

Dominant mutations in the gene GJB2 cause keratitis-ichthyosis-deafness (KID) syndrome, a severe condition affecting the skin, cornea and inner ear. GJB2 encodes the protein connexin-26 (Cx26) which forms hemichannels or gap junction channels allowing the passage of signalling molecules. Approximately 80% of KID syndrome patients carry a c.148G > A (p.D50N) mutation in GJB2, which results in aberrant channel function. We hypothesised that silencing of the mutant allele in patient keratinocytes using allele-specific siRNA could correct the channel function. First, to confirm whether patient ker

Methods: A prospective observational study of 252 severe MK patients was conducted with follow-up at days 7, 14 and 21 post-enrolment.

Abstract:

Microbial keratitis is the most serious, and only potentially blinding complication of contact lens wear. To further understand and reduce the risk of this disease, incidence rates and risk factors have been estimated in numerous studies. Since these studies were conducted, new lens types have been introduced designed to reduce the risk of infection. It was hypothesised that the issues of contact lens related hypoxia and poor lens hygiene could be addressed by the introduction of silicone hydrogel and daily disposable lenses respectively.

Abstract:

Microbial keratitis (MK) is a leading cause of blindness in the developing world. Pseudomonas aeruginosa (PA) is the most common pathogen isolated from contact lens related MK, and is usually associated with significant visual complications. The intact corneal epithelium forms a strong barrier to bacterial penetration into deeper tissue, and only when bacteria reach the stroma, through a breach in the epithelium, does a typical ulcer develop, with stromal suppuration and necrosis. Since corneal fibroblasts are one of the most prominent cellular components in the stroma, they probably have an i

Acanthamoeba mannose-binding protein (AcMBP) is a virulence factor of the free-living amoeba, Acanthamoeba castellanii.

Therapeutic unresponsiveness is attributed to similarities in the biological processes that Acanthamoeba shares with humans and its ability to form drug-resistant cysts.

Acanthamoeba are ubiquitous protists that play an environmental role in regulating microbial diversity; they also occasionally cause infections of the eye (Acanthamoeba keratitis) and brain (granulomatous amoebic encephalitis). These organisms exhibit two distinct phenotypes. The trophozoite form dominates in favorable conditions, in which the Acanthamoeba move through the extension of pseudopodia, engulfing microbes and other particles. During stressful conditions, the Acanthamoeba undergo a process of encystment, in which they build a double cell wall and become relatively inactive. The

Abstract:

[Truncated abstract] The cornea plays a major role in the refraction of light and thus the maintenance of its transparency is critical for optimal vision. Infection or trauma can initiate a host inflammatory response, which can cause edema of the collagenous stroma. This tissue edema compromises vision by disrupting the regular arrangement of the corneal stromal lamellae, whose organization is critical to its refractive properties. Until recently, it was the accepted dogma that the cornea was an immune privileged tissue owing in part to its avascular nature and paucity of resident macrophages

In this work, we have identified a MAP kinase (MAPK), highly similar to fmk1 in F. oxysporum, belonging to the YERK1 subfamily of extracellular regulated kinases.
