V. Parasites of cattle are described and illustrated. Life-histories and methods of control are discussed.
The following parasites are dealt with: -Haematopinus eurysternus, Linognathus vituli, Bovicola bovis, Boophilus microplus, Lyperosia exigua, Paramphistomum cervi, Fasciola hepatica, Moniezia...

HARES.-Pasteurella pseudotuberculosis rodentium infection is the most important disease; it...

In 1937 there was a high mortality among roe deer in Lithuania, and 92.5% of those affected were young animals. Verminous pneumonia due to Dictyocaulus viviparus was determined as the cause of death, the bad weather of the year being a predisposing factor.-A. PABIJANSKAS (KAUNAS).

BOVINE TUBERCULOSIS eradication is carried on in co-operation with the U.S.A. Bureau of Animal Industry. 1, 242, 325 cattle were tested and 0.2% reacted. All...

None of seven suspected cases of ANTHRAX were confirmed. Vaccination of 1, 298 cattle with ANTHRAX spore vaccine was carried out by the Veterinary Staff.
Clostridum chauvoei was identified as the cause of deaths in ten outbreaks of BLACKLEG. The disease occurs throughout the island.
In a pilot...

Intradermal palpebral tests were carried put on cattle suspected of being infested with liver fluke and on sheep with Dictyocaulus filaría, the antigen being in each case prepared from the worms. It was stated that reactions occurred which S. considered to be specific. Details were given of the...

VI. T. emphasized the economic importance of sub-clinical parasitic infestation, and discussed host-parasite relationships and the control of parasites in high stock concentrations.
The relation between fog fever and lung-worm infestation is still confused. Experimental work with calves indicates...

MASTITIS due to Bact. coli and Bact. aerogenes was reported. STAPHYLOCOCCAL MASTITIS is still a problem and does not respond well to streptomycin, streptomycin-penicillin, aureomycin or dibromopropamidine. TUBERCULOSIS appears to be more prevalent in beef cattle than was anticipated. The policy of...

P. described two techniques for: -(a)estimating the number of larvae of D.viviparus per g. of faeces; and (b) the detection and enumeration of larvae of D. viviparus in herbage.-T. E. GATT RUTTER.

Recovery from an initial lungworm infection conferred a strong resistance to reinfection in 9 of 11 young cattle. However, acute symptoms developed in animals whose resistance was initially challenged with over 200, 000 infective larvae; one animal died. Animals whose resistance was repeatedly...
