Seasonal incidence of adiaspores of Emmonsia crescens emmons & Jellison 1960 in wildly living animals

Summary In a collection of rodents from one locality a remarkable irregularity of monthly incidence of lung adiaspores was observed. The highest frequency of infection was ascertained in animals captured in April and May. The authors consider this phenomenon to be important for the elucidation of the life cycle ofEmmonsia crescens in nature.     

动物的孤雌生殖

孤雌生殖（parthenogenesis）也叫做“单性生殖或处女生殖”。孤雌生殖的定义是：“雌性个体产生的卵,无需受精．可发育成新雌性个体。”植物也可能有类似的情形,但植物受精作用的细节多少有些不同,所以这个定义只适用于动物。     

Mycotoxicoses of animals

Mycotoxicoses are intoxications caused by ingestion of foodstuffs contaminated with mycotoxins, i.e. toxic secondary metabolites of microscopic filamentous fungi (moulds). By field observations and by experimental testing, toxins or toxic strains of more than 100 species of fungi have been encountered. However, causal associations have so far only been established for a small number of mycotoxicoses in farm animals, and the more important mycotoxicoses are aflatoxicosis, facial eczema, mycotoxic nephropathy, and estrogenic syndrome. A full assessment of the impact of mycotoxins on the health of farm animals can hardly be made at present, because the amount of surveillance data from mycotoxicoses is very limited, due mainly to inadequate diagnostic criteria. A new set of criteria for the diagnosis of mycotoxicosis is proposed, which has been successfully applied in the causative study of mycotoxic porcine nephropathy.
