Macro anatomical investigation of brachial plexus of the White New Zealand rabbit (Orycotolagus cuniculus)

In present study, the brachial plexus of the White New Zealand rabbit (Orycotolagus cuniculus) was investigated. Five adult rabbits were used and organizations of the brachial plexus of them were investigated. It was found that the brachial plexus of the rabbit was formed by rami ventralis of fifth cervical spinal nerve (C5), sixth cervical spinal nerve (C6), seventh cervical spinal nerve (C7), eighth cervical spinal nerve (C8), first thoracic spinal nerve (T1) and second thoracic spinal nerve (T2). The rami ventralis of C5 spinal nerve and T2 spinal nerve were divided into two branches. The caudal branch of C5 spinal nerve and cranial branch of T2 spinal nerve contributed to the brachial plexus. The caudal branch of C5 spinal nerve and C6 spinal nerve constituted the cranial trunk and the caudal trunk was formed by a branch which came from cranial trunk, rami ventralis of C7, C8, T1 spinal nerves and the cranial branch of ventral ramus of T2 spinal nerve. Contribution of caudal branch of ventral ramus of C5 spinal nerve and cranial branch of ventral ramus of T2 spinal nerve to the formation of the brachial plexus of rabbit and division of the brachial plexus to the caudal and cranial trunks resemble to porcupine and differ the brachial plexus of this species from those of rat, mouse and mammals.Key words: Spinal nerves; Orycotolagus cuniculus; Brachial plexus; Rabbits.DOI: http://dx.doi.org/10.3329/ijns.v1i3.8825International Journal of Natural Sciences (2011), 1(3):74-76

Prevalence of zoonotic parasitic diseases of domestic animals in different abattoir of Comilla and Brahman Baria region in Bangladesh

A study was conducted to investigate about the prevalence of parasitic diseases indifferent abattoirs in selective area of Bangladesh such as Comilla and Brahmon Baria districts.Animals were examined for post-mortem defects in different abattoirs of those districts. The studystarted from February, 2008 to August, 2008. The total examined animals were 3510, among them1460 cattle, 620 buffaloes, 970 goats and 460 sheep. Age, sex and breed of the examined animalswere recorded as far as practicable. The overall prevalence of hydatidosis was highest (26.01%)followed by fascioliasis (20.74%), amphistomiasis (19.62%). The prevalence of above mentioneddiseases was higher in older animals. The prevalence of hydatidosis, fascioliasis andamphistomiasis was higher in male in case of cattle and goats. But the prevalence of thosediseases was distinctly higher in female animals in case of buffaloes and sheep. The proportionalprevalence of different disease conditions in cattle was much higher in Hariana breed than those oflocal and crossbred cattle.Key Words: Abattoirs; zoonotic diseases; parasites; domestic animal.DOI: 10.3329/ujzru.v28i0.5281Univ. j. zool.
