Fresh droppings were collected from six species of bird of prey (Falconiformes and Strigiformes). Bacteriological examination revealed that the birds' digestive systems were colonised by bacteria found widely in other species of animals. Throughout the survey no Salmonella species were isolated.

Ulceration and necrosis of the rostrum in Darwin's frogs was investigated microbiologically and histopathologically. The condition was attributed to infection with Aeromonas liquefaciens and, possibly, an Acinetobacter sp.
A simple barrier system was used successfully to exclude Mycoplasma pulmonis and Sendai virus from a conventional mouse room. 49 weeks after introduction of the barrier system of management Pasteurella pneumotropica was first isolated from animals in the room.
The feet of 63 domestic poultry and 37 birds of prey were swabbed and cultured. Staphylococcus aureus was isolated from 4 X 7 per cent of the former and 10 X 8 per cent of the latter. The recovery of S epidermidis was considerably higher, the organism being cultured from 80 X 9 per cent of poultry and 62 X 1 per cent of birds of prey. The significance of the low S aureus isolation rates is discussed in relation to avian staphylococcal infections and attention is drawn to the importance of the choice of plasma for the coagulase test when identifying S aureus from non-human sources.
An outbreak of shigellosis due to Shigella sonnei, is reported in laboratory maintained marmosets (Callithrix jacchus) and tamarins (Saguinus nigricollis). The clinical signs and pathological lesions are described and the microbiological findings discussed. Control of the disease was based upon hygiene and antibiotic therapy and the consequences of this approach are described in detail.

Over a 3-year sampling period Lactobacillus sp. has been isolated from the livers of barrier-maintained and conventional mice. Serology has failed to detect presence of mouse hepatitis virus antibodies in any of these mice. Histopathological examination revealed only mild fatty change and small monocytic infiltrates.
