The morphology of 50 Oesophagostomum of each sex from cattle from various districts of the Amur region, USSR, was studied in order to establish their identity. Despite differences in measurements from those given by other researchers and variations in the arrangement of bursal rays, it is concluded ...

In the Far East of the USSR, Mecistocirrus ova and larvae do not survive the winter. Tetramisole at 0.01 g/kg body weight in feed was 100% effective against both immature and mature nematodes in cattle in the Amur region. However, treatment against immature nematodes resulted in higher weight gains ...

Several anthelmintics were tested against natural Bunostomum infection in cattle in the Amur region, USSR. Fenbendazole at 0.01 g/kg body weight (as Panacur 20% granules) and tetramisole at 0.015 g/kg (as 20% granules) were 100% effective, but tetramisole caused short-term distress and was...

Cattle from 7 farms in 6 zones of Kazakhstan, USSR, was investigated for dictyocauliais. The prevalence of infection reached, on some farms, 88.8% and often resulted in clinical disease. Cattle grazed on flood meadows and mountain pastures were particularly at risk. The prevalence of infection on...

Analysis of meteorological factors in the mountain district of the Kegensk region, Kazakh SSR, for the past 15 years and of helminthological data indicates that ambient temperature, particularly on the soil surface, is the most important factor limiting the development of Dictyocaulus viviparus ...

Cattle with natural Oesophagostomum infection in the Amur region of the USSR were treated with tetramisole granules at the minimal therapeutic dose of 8 mg/kg body weight, or with cambendazole at 20 mg/kg. Both drugs were mixed in food and given once after a fast of 12 h. Cambendazole (judged on...

In the USSR, bovine Mecistocirrus infection occurs only in the far-eastern regions. Investigation of dairy and fattening farms showed a prevalence of infection ranging from 23.8 to 100% in adults and 0 to 100% animals in > one year old. In liquid manure, Mecistocirrus ova may survive for 16 to 18...

Instruments for fixing the head of cattle, for obtaining material for intra vitam diagnosis of Thelazia in cattle, for galvanocautery against T. rhodesi and a treatment gun suitable for injecting anthelmintic compounds against T. gulosa and T. skrjabini are described. All these instruments were...
