Studies on the prevalence of the swine kidney wormStephanurus dentatus in Rohilkhand Division of Uttar Pradesh (India)

Abstract: Stephanurus dentatus (Diesing, 1839), (Nematode: Strongyloidea), popularly known as the swine kidney worm, is generally found in the peritoneal fat, the peMs of the kidney, the walls of ureters and in the liver of pigs. Occasionally it may occur in the lungs, abdominal and thoracic organs and even in the spinal cord (Bui-lap, 1966) and lumbar muscles (Xu, 1984). It is widespread in tropical and subtropical areas and is reported to cause substantial economic loss to the pig industry (Hale, 1986). The losses are mainly caused by retardation in the growth rate and reduced feed efficiency of the host and in condemnation of the liver, kidneys and other edible parts that are invaded by the migrating larvae. Norton (1975) found that 29.6% of the pigs in Townsville (Australia) were infected with S. dentatus, whereas Rodriguez (1980) reported an infection rate of 35% in pigs in Cuba. Hale (1986) reported a prevalence of 78-94% in some of the southeast states of the USA, while Gibbens et al. (1989) reported an infection rate of 42% in Belize. No similar survey has been conducted in the plains of India.

Identification of Bipolaris maydis race T pathogenic to Populus deltoides

Abstract: Isolates of Bipolaris maydis pathogenic to Populus deltoides were identified to be race T on the basis of their virulence to certain male-cultivars of the host from Texas provenance, toxin production, sclerolia formation, light pigmentation and poor sporulating potency on the culture media under controlled conditions.
