An investigation of surface albedo variations during the recent Sahel drought
Abstract Applications Technology Satellite (ATS) 3 green sensor data are used to measure surface reflectance variations in the Sahara/Sahel during the recent drought period 1967–74. The magnitude of… Expand

Eimerian oocysts were found in 98% of 422 faeces samples from goats in SE England. It was found that 74% of the samples contained thousands or tens of thousands of oocysts/g. Kids less than 1 year… Expand
The immunity arising from continuous low-level infection with Eimeria tenella.
The species of coccidia occurring in cattle and sheep in the South-West of England.
A series of line drawings of the unsporulated and sporulated oocysts of the species of Eimeria found in cattle and sheep in Britain has been compiled. The incidence of the different species in faecal… Expand
Experiments with defined multispecific coccidial infections in lambs.
The behaviour of four species of Eimeria was studied in lambs which were given either monospecific or multispecific infections. In the presence of other species the patency of oocyst production of E.… Expand
Redescriptions of Eimeria irresidua Kessel & Jankiewicz, 1931 and E. flavescens Marotel & Guilhon, 1941 from the domestic rabbit.
Eimeria flavescens and E. irresidua from the domestic rabbit are redescribed. The relatively smaller ovoidal oocysts of E. flavescens which measure on average 31.7 X 21.4 micrometer, possess a wide… Expand
The oocyst sporulation time of Eimeria species from the fowl.
Freshly isolated oocysts were sporulated at 29 degrees C with constant aeration. Minimum sporulation time was determined by dosing the developing oocysts at intervals of 1 h to successive groups of… Expand
The occurrence of Eimeria weybridgensis and other species of coccidia in lambs in England and Wales.
SUMMARY Four-hundred-and-sixty-three faeces samples from lambs up to 5 months old from Wales, Northern England and South-East England were examined for coccidia. 95 · 5 per cent were positive, most… Expand
The drug sensitivity of recently isolated strains of Eimeria meleagrimitis and a laboratory strain of Eimeria adenoeides in turkeys to robenidene.
A comparison of two laboratory strains of Eimeria tenella.
