Chromosomal Analysis of Bothriocephalus Acheilognathi Yamaguti, 1934 (cestoda: Pseudophyllidea) in Jammu and Kashmir

چکیده
The diploid complements of mitotic metaphase plates of Bothriocephalus acheilognathi (Yamaguti), a specific parasite of Schizothorax spp. were studied using conventional Giesma staining and karyometric analysis. Bothriocephalus acheilognathi showed a karyotype with 2n = 14 chromosomes which are all biarmed metacentric, meta-submetacentric and submetacentric. The chromosomes are small – their total length ranges from 2 to 8.3 μm. For Karyotyping, chromosomes were cut out of the photomicrographs and paired on the basis of size and centromere position. Relative lengths of chromosomes were calculated by the division of the individual chromosome length by the total haploid length. Centromeric indices (Ci) were determined by the division of the length. Measurements are based on all chromosomes from 10 metaphase spreads for each species.

Occurrence of Bothriocephalus acheilognathi in cyprinid fish from three lakes in the flood plain of the Yangtze River, China.
Cyprinid fish, Hemiculter leucisculus, Cultrichthys erythropterus and Culter dabryi, were sampled from Liangzi, Honghu and Tangxun lakes in the flood plain of the Yangtze River. The cestode Bothriocephalus acheilognathi Yamaguti, 1934 was found in the 3 lakes, but C. erythropterus sampled from Liangzi lake was found uninfected due probably to the small sample size. Findings of the cestode in th...

Seasonal surveys were conducted at the Vaal Dam between April 2000 and January 2001. Twenty smallmouth yellowfish (Labeobarbus aeneus) and 20 largemouth yellowfish (Labeobarbus kimberleyensis) were collected with the aid of gill nets. Surface water quality variables were included. The cestodes were identified as either Bothriocephalus acheilognathi Yamaguti, 1934 or "other cestode spp.". The ma...

This paper provides the first report of the invasive Asian fish tapeworm, Bothriocephalus acheilognathi Yamaguti, 1934, in Honduras. The cestode was found in Profundulus portillorum (Cyprinodontiformes: Profundulidae), which represents a new host record, and which is a member of a genus faced with a variety of conservation challenges, now potentially complicated by the presence of this pathogen...
متن کاملThe distribution of the introduced tapeworm Bothriocephalus acheilognathi in Australian freshwater fishes.
Native and exotic fishes were collected from 29 sites across coastal and inland New South Wales, Queensland and Victoria, using a range of techniques, to infer the distribution of Bothriocephalus acheilognathi (Cestoda: Pseudophyllidea) and the host species in which it occurs. The distribution of B. acheilognathi was determined by that of its principal host, carp, Cyprinus carpio; it did not oc...
