Two colonies of urban feral cats were subjected to a programme of population control by trapping, neutering and returning to site. The behaviour of individual cats and the stability of the groups was studied before and after the programme, which was then assessed in terms of its humaneness and effectiveness as a means of control. The method was satisfactory on both counts and may be recommended for controlling feral cat colonies where the welfare of the cats can be assured after their return.

In a survey of 259 newly-imported rhesus monkeys, 5 species of nematode parasites were commonly found. Of these 5 species, Oesophagostomum spp. and Strongyloides fulleborni were implicated in the deaths of 3 monkeys. 5 other nematode species, 2 cestode species and 1 trematode species were also found; their pathogenicity is discussed. The results of treatment of parasitic infections with 6 different drugs is reported. Thiabendazole at an initial dose of 100 or 133 mg/kg and repeated at 50 mg/kg was found to be the most effective treatment against Oesophagostomum spp.

Of 21 newly-imported rhesus monkeys, 11 showed a typical macular rash and 13 developed a 4-fold or greater rise in antibody titre to measles. 5 animals died, 4 of them with extensive pneumonia, pleurisy and pericarditis. Although measles was involved in each case, there were contributory causes of death, namely Diplococcus pneumoniae and Staphylococcus aureus infection, and infestation with Oesophagostomum (nodular worm) larvae.

1. The uptake of the inhibitors N-ethylmaleimide (NEM) and 1-fluoro-2,4-dinitrobenzene (DNFB) by human red cells has been correlated with the inhibition of glucose exit.2. With both inhibitors there was an initial rapid uptake by the cells with little inhibition; this was followed by a phase when inhibition was developing rapidly but uptake continued at a steady rate even after the development of inhibition had flattened off.3. The rate of uptake of DNFB during the rapid development of inhibition corresponded to about 4 x 10(8) molecules/cell for 100% inhibition, irrespective of the temperature of incubation. This cannot be used as an estimate of the number of glucose transfer sites in the cell membrane because of the lack of specificity.4. In an examination of lipids from red cells incubated with [(14)C]DNFB, labelling associated with lipids was eluted with peaks in chloroform-methanol 4:1 and 1:4 respectively. Thus, although DNFB is normally regarded as a protein reagent, involvement of lipids in the transfer of glucose could not be excluded.
