Numerous methods have been tried for reducing the bacterial count of calf lymph without diminishing its potency. Gins (1924) and Lehmann (1937) have used carbolic acid as an agent for the destruction of bacteria in lymph. Stevenson and Butler (1936) drew attention to the value of phenol as an agent for preventing accidental contamination of lymph. They found that lymph made up into 50 per cent ...

White mice were exposed to atmospheres containing known amounts of atomized influenza A virus (PR8 strain) of constant potency under conditions of varying humidity. It was found that an amount of atomized virus suspension which produced a 100 per cent mortality rate in animals exposed at 30 and 80 per cent relative humidity, respectively, resulted in the death of only 22.5 per cent of mice at a...

The purpose of this study was to evaluate the interaction effects winter cover crops (hairy vetch, subclover and black oat) a bare soil, crop biomass management (incorporated into soil or left on surface as death mulch), nitrogen (N) fertilization level (0, 75 150 kg ha−1 N) fruit yield quality parameters processing tomato. Hairy vetch residues increased (+57%), color index (+8%) sugar/acidity ...

Three experiments were conducted to evaluate the nutritional value of bitter vetch. Experiment 1 was conducted to determine the metabolisable energy content of bitter vetch. Sixteen adult Leghorn roosters were used. Forty grams of bitter vetch were precision-fed individually to 12 roosters. In addition, 4 birds were not fed and served as a control treatment in the measurement of metabolic fecal...

Multidrug-resistant organisms are increasing worldwide. Over the years we have noted increasing resistance of organisms isolated in our neonatal unit. There is a need therefore to scrutinize the problem so as to be able to plan for the future. Over a 5-month period, 716 infants were admitted of which 192 were screened for sepsis. Overall, 121 (16.7 per cent) had positive blood cultures. The pre...
