Studies on Calf Diarrhoea in Mozambique: Prevalence of Bacterial Pathogens

The prevalence of diarrhoea in calves was investigated in 8 dairy farms in Mozambique at 4 occasions during 2 consecutive years. A total of 1241 calves up to 6 months of age were reared in the farms, and 63 (5%) of them had signs of diarrhoea. Two farms had an overall higher prevalence (13% and 21%) of diarrhoea. Faecal samples were collected from all diarrhoeal calves (n = 63) and from 330 hea...

Further studies on partially purified calf thymus DNA polymerase a.

Attempts to prevent the urea conversion of a 200-230,000 molecular weight DNA polymerase alpha to a 150-170,000 molecular weight form by the inclusion of protease inhibitors have not been successful. No other method has been found capable of dissociating a 50-70,000 fragment or subunit from the DNA polymerase subunit. Addition of this 50-70,000 subunit to the polymerase subunit does not aid the...

THERMODYNAMIC STUDIES OF THE INTERACTION OF SODIUM N-DODECYL, SULPHATE WITH CALF - THYMUS WISTONE H3

The binding of Sodium n-dodecyl sulphate (SDS) to histone H3 was studied in the pH range 3.2-10 by equilibrium dialysis at 27? and 3 7 ?c .T he binding data have been used to obtain the Gibbs free energy of interaction using a theoretical model of the Wyman binding potential; and the enthalpy of interaction from the temperature dependence of theequilibriumconstantsfronr theVan't Hoff re1ati...

Morphological studies on the rete mirabile epidurale in the calf.

Further studies on the fractionation of calf thymus histone.

The fractionation of calf thymus histone has been studied in the past few years by many investigators. The gross separation of this mixture into fractions which differed in physicochemical properties, or its more minute resolution into components that were presumed, in some instances, to be fairly homogeneous has been reported by the following workers: Ahlstrom (l), Stedman and Stedman (2), But...
