The objective of the present study was to determine whether there was an association between the in vitro antimicrobial susceptibility test results of subclinical mastitis pathogens and bacteriological outcomes of intramammary treatments using cefquinome. A total of 110 intramammary pathogens from 51 cows were assessed in this study. Most intramammary infections were due to coagulase-negative s...
Mastitis is the inflammatory reaction of the udder to invading pathogens. One of the most apparent reactions is the increased influx of immunoreactive cells from blood into milk inducing a dramatic increase of milk somatic cell counts (SCC). We have investigated (i) the relationship between log SCC/ml in infected quarters being >6 (n = 8, group I) or varying between 5.4 and 6 (n = 8, group II) ...
Despite significant progress in the control of contagious pathogens, environmental mastitis continues to be a major cause of financial loss to the UK dairy industry. This paper presents some findings from a field study designed to investigate the incidence and significance of coliform infections acquired during the non-lactating period. The bacteriological status of two quarters from each of 62...
this is an original study on the effect of a polyisobutylene – polydimethylsiloxane (pibpdms) block copolymer modifier used as an interfacial active agent on the dynamics behaviour of single newtonian drops suspended in a polyisobutylene (pib) newtonian matrix. the results were divided in two sections. the first part included the experiments carried out on the non-modified and 2% block cop...
We present empirical evidence on acquirer firms that have violated or are about to violate a loan covenant within four quarters of undergoing an acquisition. We find that firms that violate a covenant within the four quarters before the acquisition announcement have the highest announcement period abnormal returns, while firms that violate a covenant within the four quarters after the acquisiti...
This study compared the different leucocyte populations in milk from udders infected with different mastitic pathogens and in different stages of infection. Milk samples were collected from quarters free of intramammary infection, acutely infected with Escherichia coli or Staphylococcus aureus and chronically infected with S. aureus, coagulase-negative staphylococci (CNS) or Streptococcus dysga...
