SUR7 deletion in s impacts extracellular vesicle features and delivery of virulence factors.

Extracellular vesicles (EVs) from human fungal pathogens have been implicated in fungal virulence, yet little is known about their role in the host-pathogen interaction. Progress has been hampered by the lack of a specific marker for fungal EVs that can be used to monitor EV isolation and tracking in biological systems. Here we report the effect of a gene knockout on the production, properties, and role of EVs in the virulence of .

Surgery for rheumatic heart disease in the Northern Territory, Australia, 1997-2016: what have we gained?

Background: Between 1964 and 1996, the 10-year survival of patients having valve replacement surgery for rheumatic heart disease (RHD) in the Northern Territory, Australia, was 68%. As medical care has evolved since then, this study aimed to determine whether there has been a corresponding improvement in survival.

Methods: A retrospective study of Aboriginal patients with RHD in the Northern Territory, Australia, having their first valve surgery between 1997 and 2016.

Association between alcohol restriction policies and rates of alcohol-related harms in remote Australian Aboriginal and Torres Strait Islander communities: a systematic review.

Objective: The objective of this review was to examine the association between alcohol supply restriction policies and rates of alcohol-related harms in remote Australian Aboriginal and Torres Strait Islander communities.

Introduction: Aboriginal and Torres Strait Islander peoples living in remote communities experience a higher rate of alcohol-related harms than other Australians. High rates of alcohol consumption are associated with a range of physical and social harms.

Semi-quantitative digital analysis of polymerase chain reaction-electrophoresis gel: Potential applications in low-income veterinary laboratories.

Aim: The interpretation of conventional polymerase chain reaction (PCR) assay results is often limited to either positive or negative (non-detectable). The more robust quantitative PCR (qPCR) method is mostly reserved for quantitation studies and not a readily accessible technology in laboratories across developing nations. The aim of this study was to evaluate a semi-quantitative method for conventional PCR amplicons using digital image analysis of electrophoretic gel.

A molecular ecological approach to the detection and designation of the etiological agents of a model polymicrobial disease.

The application of the original Koch postulates and the molecular Koch postulates in the definition of the etiological agents of polymicrobial diseases has received little or no attention. In the present study, denaturing gradient gel electrophoresis (DGGE) of oral samples (n = 3) from each of 3 categories of animals (healthy, diseased [gingivitis], and then oxytetracycline-treated) was used and revealed different bacterial community structures in a model polymicrobial disease (gingivitis) and after clinical cure. Potential microbes associated with the disease and belonging to the following families were identified: Fusobacteriaceae, Porphyromonadaceae, Flavobacteriaceae, Alcanivoracaceae, Bacteroidaceae, Xanthomonadaceae, and Neisseriaceae.

A molecular survey of a captive wallaby population for periodontopathogens and the co-incidence of Fusobacterium necrophorum subspecies necrophorum with periodontal diseases.

Periodontal diseases (PD) are diseases of polymicrobial aetiology and constitute major health problems in captive macropods. Increasing knowledge of the causal pathogens is therefore crucial for effective management and prevention of these diseases. PCR survey and sequence analyses of potential periodontopathogens in captive wallaby populations revealed a co-incidence of the diseases with the detection of Fusobacterium necrophorum subsp.
