Nasal mupirocin has an important role to play in the prevention of Staphylococcus aureus infection by eliminating nasal carriage of this organism. Indeed, in many countries nasal mupirocin is one of the mainstays for controlling outbreaks of methicillin-resistant S. aureus. Eradication of nasal S. aureus with mupirocin has been shown to be effective in preventing postoperative infections in patients undergoing cardiothoracic surgery and in preventing exit-site infections in patients undergoing haemodialysis. ⋯ Low-level resistance does not represent a significant clinical problem but high-level resistance resulting from indiscriminate use may give grounds for concern. Further review of these issues is required. As with any antibiotic, mupirocin should be used judiciously, as part of an integrated programme of infection control.

Fungal infection in critically ill patients is an increasingly prevalent problem. Candida spp. cause the majority of these infections in ICU. They occur most commonly in patients with severe underlying illness, multiple courses of antibiotics and intravascular catheters. ⋯ Most patients are diagnosed using inferential evidence of infection, such as persistent pyrexia despite antibiotics, raised serum C-reactive protein and the presence of individual risk factors. Amphotericin B and fluconazole are the most commonly used anti-fungals dependent on the identity of the fungus. Most of these infections are endogenous; however, a proportion may be caused via the hands of healthcare staff or contaminated medical equipment.

Several reports have documented the presence of vancomycin-resistant enterococci (VRE) in the stools of asymptomatic individuals from the community who have neither recently been in hospital nor received antibiotics. Such findings were contrary to the then existing perception of VRE as a strictly hospital-acquired infection of debilitated and immunocompromised patients on specialized units. Community-acquired infections with VRE are extremely rare but those that do occur may be conspicuous because of their serious nature, for example, endocarditis. ⋯ As long ago as 1969, the Swann report declared that an antibiotic of medical importance should not be used as a growth promoter in animal feeds. The vasy array of antibiotics now being used in animal husbandry and fish-farming, and the cross-resistance of some antibiotics to their medically important counterparts is a real cause for concern. The emergence of multi-resistant enterococci causing human infections and the possibility of the transfer of the VanA gene from VRE to methicillin-resistant Staphylococcus aureus (MRSA) emphasizes the importance of this problem.

The supply of food to patients and staff is the responsibility of hospital support services. This article considers the provision of catering services and the production of safe food in hospitals in the UK. The responsibilities of food handlers and the role of the infection control team, the environmental health officer and the occupational health staff are also described.

Transmission of Burkholderia (Pseudomonas) cepacia by close contact with colonized patients is well documented, and minimizing social contact between cystic fibrosis (CF) patients by segregation and cohorting of B. cepacia colonized patients has achieved some success in controlling the nosocomial and community spread of this organism. However, direct and indirect environmental transmission still occurs. There is evidence for transmission of B. cepacia to CF patients via pulmonary test equipment, nebulizers and other respiratory equipment used both in CF centres and for homecare, but little or no evidence of spread through aerosols, dental equipment, hands, contaminated disinfectants and water supplies. Infection control procedures for reducing the transmission of B. cepacia are discussed.
