The popularity of open farms and petting zoos has increased markedly over the last 5 years, with most children in developed countries now having the opportunity to visit such a facility at some stage in their childhood, either through school or family visits. The open access policy of these establishments allows visitors to be in direct contact with animals such as sheep (lambs), goats, cats (kittens), dogs (puppies), and birds and to have the opportunity to feed such animals. This contact may lead to the transmission of microbial pathogens from animals to humans, e.g., Escherichia coli O157:H7, resulting in human disease. This review outlines the causal organisms associated with such zoonoses, a description of previous outbreaks at farms and zoos, as well as infection control measures to help prevent such zoonotic infections.

Faecal prevalence of gastrointestinal bacterial pathogens, including Campylobacter, Escherichia coli O157:H7, Salmonella, Shigella, Yersinia, as well as Arcobacter, were examined in 317 faecal specimens from 44 animal species in Belfast Zoological Gardens, during July-September 2006. Thermophilic campylobacters including Campylobacter jejuni, Campylobacter coli and Campylobacter lari, were the most frequently isolated pathogens, where members of this genus were isolated from 11 animal species (11 of 44; 25%). Yersinia spp. were isolated from seven animal species (seven of 44; 15.9%) and included, Yersinia enterocolitica (five of seven isolates; 71.4%) and one isolate each of Yersinia frederiksenii and Yersinia kristensenii. Only one isolate of Salmonella was obtained throughout the entire study, which was an isolate of Salmonella dublin (O 1,9,12: H g, p), originating from tiger faeces after enrichment. None of the animal species found in public contact areas of the zoo were positive for any gastrointestinal bacterial pathogens. Also, water from the lake in the centre of the grounds, was examined for the same bacterial pathogens and was found to contain C. jejuni. This study is the first report on the isolation of a number of important bacterial pathogens from a variety of novel host species, C. jejuni from the red kangaroo (Macropus rufus), C. lari from a maned wolf (Chrysocyon brachyurus), Y. kristensenii from a vicugna (Vicugna vicugna) and Y. enterocolitica from a maned wolf and red panda (Ailurus fulgens). In conclusion, this study demonstrated that the faeces of animals in public contact areas of the zoo were not positive for the bacterial gastrointestinal pathogens examined. This is reassuring for the public health of visitors, particularly children, who enjoy this educational and recreational resource.

This study examined a large number of water sources (n = 7904) over a 9-year period for the presence of Pseudomonas aeruginosa. The study highlighted that jacuzzis (n = 5811; 7% positive) and hot tubs had the highest occurrence of this organism (n = 243, 21% positive). Patients with cystic fibrosis (CF) are interested in knowing what water environments are likely to be contaminated with this organism, as this bacterium is an important cause of increased morbidity and mortality in such patients. With such information, CF patients and parents may make informed decisions about lifestyle choice and water environment avoidance.

Background: Patients with cystic fibrosis have increased morbidity/mortality due to chronic respiratory infections, which primarily originate from the environment. Infection prevention and control emphasize the importance of cleaning and disinfection of respiratory devices, however, there is a paucity of guidance on toothbrush hygiene, which have been shown to be a source of cystic fibrosis (CF) pathogens. Methods: This study examined steam disinfection of toothbrushes contaminated with clinically significant CF isolates (n = 80; Gram positive = 33; Gram negative = 32, and non-tuberculous mycobacteria = 6) and yeasts (n = 9), as well as oral streptococci (n = 26) and environmental Pseudomonas aeruginosa (n = 12). Results: Steam disinfection eradicated all organisms tested, as well as all organisms in CF sputum applied to toothbrushes. Conclusions: Steam disinfection offers a relatively simple, cheap and available method of eliminating non-spore-forming CF pathogens on toothbrushes. Toothbrushes should be thoroughly rinsed after each use before steam disinfection, to remove plaque, epithelial cells, and residual toothpaste. Toothbrushes should be steam disinfected after each use employing a baby bottle steam disinfector, adhering to manufacturers' operating instructions and stored in the disinfector until next used within 12 to 24 hours. Toothbrushes should be replaced every 3 to 4 months, or sooner if the bristles look worn out, as well as every time a pulmonary exacerbation occurs or every time the patient is treated for a pulmonary/throat infection. Steam disinfection of toothbrushes is crucial when the patient is undergoing eradication regimes for P. aeruginosa and methicillinresistant Staphylococcus aureus, so that the patient does not become reinfected from this source, thereby aiding eradication and enhancing patient safety.
