Putting it into practice: Infection control professionals' perspectives on early career nursing graduates' microbiology and infection control knowledge and practice.

Background: The microbiology component of Australian undergraduate nursing programmes varies considerably. Any actual or potential impact of this variation on infection control practice, as a nursing graduate, is relatively unknown.

Aims: The aim of this study was to explore infection control professionals' perceptions of the importance of microbiology and infection control training in undergraduate nursing curricula and the perceived retention of that knowledge and its transferability to practice.

Genetic characterization of equine adenovirus type 1.

Two known serotypes of equine adenovirus (EAdV), equine adenovirus type 1 (EAdV-1) and equine adenovirus type 2 (EAdV-2) have been isolated from horses. EAdV-1 is predominantly associated with upper respiratory tract infections while EAdV-2 appears to be associated with gastrointestinal infections in horses. In this report the EAdV-1 genome has been sequenced for the first time.

Pre-treatment with a non-therapeutic dose of cisplatin increases solid tumour response to liposomal-p53 gene therapy- An in vivo study.

Successful liposomal-mediated gene therapy is often limited by poor transfection efficiencies. One method previously shown to increase the efficiency of liposomal gene delivery is through the administration of a non-therapeutic dose of the chemotherapeutic drug cisplatin prior to lipofection. The currents study aims to utilise this method to deliver lipoplexes containing the p53 tumour suppressor gene with the aim of increasing therapeutic effect of the p53 gene on a solid tumour in vivo.

Increased tumor localization and reduced immune response to adenoviral vector formulated with the liposome DDAB/DOPE.

Unlabelled: We aimed to increase the efficiency of adenoviral vectors by limiting adenoviral spread from the target site and reducing unwanted host immune responses to the vector. We complexed adenoviral vectors with DDAB-DOPE liposomes to form adenovirus-liposomal (AL) complexes. AL complexes were delivered by intratumoral injection in an immunocompetent subcutaneous rat tumor model and the immunogenicity of the AL complexes and the expression efficiency in the tumor and other organs was examined.

Antiparasitic activity of two Lavandula essential oils against Giardia duodenalis, Trichomonas vaginalis and Hexamita inflata.

Two essential oils derived from Lavandula angustifolia and Lavandula x intermedia were investigated for any antiparasitic activity against the human protozoal pathogens Giardia duodenalis and Trichomonas vaginalis and the fish pathogen Hexamita inflata: all of which have significant infection and economic impacts. The study has demonstrated that low (< or = 1%) concentrations of L. angustifolia and L.

Antibacterial activity of essential oils from Australian native plants.

To date, of the Australian essential oils, only tea tree (Melaleuca alternifolia) and Eucalyptus spp. have undergone extensive investigation. In this study a range of Australian essential oils, including those from Anethole anisata, Callistris glaucophyllia, Melaleuca spp.

Antibacterial activity of 13 honeys against Escherichia coli and Pseudomonas aeruginosa.

In this study the activity of 13 honeys, including three commercial antibacterial honeys, against Escherichia coli and Pseudomonas aeruginosa was determined. Antibacterial activity of the honeys was assayed using standard well diffusion methods. All honeys, and an artificial honey, were tested at four concentrations (10%, 5%, 2.

Modification of liposomal concentration in liposome/adenoviral complexes allows significant protection of adenoviral vectors from neutralising antibody, in vitro.

Adenoviral vectors have been commonly used in gene therapy protocols, however the success of their use is often limited by the induction of host immunity to the vector. Following exposure to the adenoviral vector, adenoviral-specific neutralising antibodies are produced which limits further administration. This study examines the efficacy of complexing liposomes to adenovirus for the protection of the adenovirus from neutralising antibodies in an in vitro setting.

Microsphere-liposome complexes protect adenoviral vectors from neutralising antibody without losses in transfection efficiency, in-vitro.

Adenoviral vectors have been commonly used in gene therapy protocols but the success of their use is often limited by the induction of host immunity to the vector. Following exposure to the adenoviral vector, adenoviral-specific neutralising antibodies are produced, which limits further administration. This study examines the effectiveness of a novel combination of microspheres and liposomes for the shielding of adenovirus from neutralising antibodies in an in-vitro setting.

In-vitro evaluation of ion-exchange microspheres for the sustained release of liposomal-adenoviral conjugates.

This study looks at the development of a novel combination vector consisting of adenovirus conjugated to liposomes (AL complexes) bound to cation-exchanging microspheres (MAL complexes). With adenovirus having a net negative charge and the liposomes a net positive charge it was possible to modify the net charge of the AL complexes by varying the concentrations of adenovirus to liposomes. The modification of the net charge resulted in altered binding and release characteristics.

Antibacterial activity of berry fruits used for culinary purposes.

Increasing interest in the health benefits of various culinary berries has led to investigation of their antibacterial activity. Commercial raspberry, blackcurrant, cranberry, and blackberry cordials (100% fruit) as well as fresh berries were assessed for their ability to inhibit the growth of various bacteria and the yeast Candida albicans. Three of the six raspberry cordials and the blackcurrant cordial inhibited all 12 bacteria and C.

Bioactivity of Backhousia citriodora: antibacterial and antifungal activity.

Backhousia citriodora products are used as bushfoods and flavorings and by the aromatherapy industry. The antimicrobial activity of 4 samples of B. citriodora oil, leaf paste, commercial tea (0.
