A new, pale form of Pedicularis groenlandica Retz. (elephant's-head lousewort) from Churchill, Manitoba is described as forma chlorina Staniforth, Maycock & Svoboda. Individuals of this form lack the normal reddish anthocyanin pigment found throughout foliage, stems and flowers of the type variety. Six mature palnts possessed old infructescences that predated their discovery by three years.
An outbreak of pox disease in Carnivora of the family Felidae occurred in the Moscow Zoo. Two forms of the disease were found: (1) fatal, fulminant pulmonary without skin lesions and (2) dermal with rash. The severity of the dermal form varied from subclinical to lethal. The pulmonary form was characterized by pneumonia and exudative pleuritis, and large concentrations of virus were observed in the lungs and exudate. In addition to Carnivora of the family Felidae, two giant anteaters had a severe form of the disease (dermal with hemorrhages) and died.
The nature and rate of neoplasia found at necropsy of captive wild animals of the Zoological Society of San Diego collection were studied. Neoplasia was present at necropsy in 2.75% of 3,127 mammals, 1.89% of 5,957 birds, and 2.19% of 1,233 reptiles. Neoplasms were not detected during 198 necropsies of amphibians. Gross and histologic examinations were performed on the 92 mammalian, 111 avian, and 28 reptilian neoplasms. The lesions were diagnosed. The findings included a high frequency of lymphosarcomas in birds and reptiles, multiple endocrine tumors in 2…
58 elephants were successfully immobilized in their natural environment in the Chobe Nation Park and on privately owned farms in Botswana using a drug mixture of etorphine (M99 Reckitt) and acetylpromazine. The specific antidote cyprenorphine (M285 Reckitt) was used in most cases to resuscitate the animals. One known mortality occurred. For the long term monitoring of social organization and long and short term movements collars manufactured from machine belting and fitted with colour codes or symbols proved most satisfactory.
Severe submandidular and ventral abdominal edema was observed in an Asian elephant (Elephas maximus) in which liver flukes ( Fasciola jacksoni) were recovered from the bile ducts at post-mortem examination. Clinico-pathologic examination of blood samples and serum from this elephant and another 8 elephants showed that most had anemia and hypoproteinemia.
