A New Technique for Counting Eggs ofFasciola hepaticain Cattle Faeces

The essential features of the method, which is described in detail, are a sieving technique to collect quantitatively theFasciola hepaticaeggs of a sample of cattle faeces, a new technique for transferring quantitatively the eggs to a measured amount of water, and a new technique for obtaining even distribution of the eggs within a counting chamber. Technical details for manufacturing the apparatus and the counting slide, designed to perform the different stages of the method, are given. The correctness of the resulting counts is demonstrated.

✓ The author describes a new technique for exposure of the cervical spine laminae in which the attachments of the semispinalis cervicis and multifidus muscles to the spinous processes are left untouched. It provides a conservative exposure through which a diverse range of posterior cervical surgeries can be performed. In contrast to conventional cervical approaches, none of the muscular attachments to the spinous processes is compromised. In this paper the author describes the technical details and discusses the applications of the procedure.

Cattle And Sheep

Although paramphistomes have been known to occur in cattle and sheep in the British Isles for-many years little precise information on the incidence, distribution and degree of infection is available. The diagnosis, except in exceptional cases, can be made only post mortem, or by the detection of eggs in the faeces. Before undertaking an investigation into this problem it was necessary to devise a simple standard technique for the collection of eggs from cattle faeces, which would be practicable not only in the laboratory but also in the field. This done, it became desirable to know firstly, within what limits egg counts were reliable criteria on which to base estimates of the number of parasites present; secondly, what was the smallest number of parasites which could be detected by faecal examination; thirdly, how much variation occurred in egg-counts from week to week in the same animals; and fourthly, if there were any variation in counts made on faeces collected at different hours of the day.
