“…It is also noteworthy that a range of environmental pathogens associated mainly with clinical mastitis were found to greater (enterobacteria, S. uberis) or lesser (P. aeruginosa) extents in asymptomatic cows. This further underlines the necessity of implementing proper hygiene management to prevent infection from the environment (McDougall et al 2009). …”

A total of 669 individual cow milk samples originating from asymptomatic cows from 16 dairy farms were examined for the presence of microorganisms with the potential to cause mastitis. Coagulase-negative staphylococci clearly predominated (53.5% positive samples) followed by streptococci and enterococci (both occurring in 16.1% samples). Among streptococci, so-called mastitis streptococci (S. uberis, S. dysgalactiae and S. agalactiae) prevailed (11.7% positive samples). Enterobacteriaceae were found in 10.0% samples, most of which (6.6% samples) were positive for Escherichia coli. Yeasts (mainly Candida spp.) were found in 8.2% samples. One of the major mastitis pathogens, Staphylococcus aureus subsp. aureus, was isolated from 9.0% of samples. S. aureus isolates were further characterised in terms of their capability to form biofilm, antimicrobial susceptibility and clonality (PFGE). All S. aureus isolates were capable of biofilm formation and were generally susceptible to the majority of tested antibiotics. The exception was ampicillin, resistance to which was observed in 27.7% isolates. Therefore, the relatively frequent occurrence of S. aureus could be attributed to persistent intramammary infections due to biofilm formation rather than low efficacy of particular antibiotics. PFGE analysis revealed clonal spread of certain S. aureus isolates within and between farms indicating that certain lineages of S. aureus mastitis strains are particularly successful.

“…The reason why such a result was obtained can be explained by the fact that the rate of udder edema is low and the udder immune system is strong in herds fed with wellbalanced rations. Udder edema is a well-recognized risk factor for mastitis in heifers (4). A combination of genetics and ration generally contributes to the development of udder edema in heifers (4).…”

“…More than 50% of all clinical mastitis occurred in the first 3 weeks of lactation. The incidence of clinical mastitis in heifers at the beginning of lactation is higher than in older cows (McDougall et al 2009;Piepers et al 2009) and heifers have a higher incidence of environmental mastitis such as Streptococcus uberis than mature cows (McDougall et al 2009). …”

The aim of this study was to evaluate the effect of postpartum mastitis between first calving and subsequent conception on production and reproduction performance as well as culling of Holstein cows. A data set of 9,183 first lactation cows was used. Results showed that the first cumulative 100 days' milk production and the milk yield standardized to 305 days were affected by the interval from calving to first mastitis (P<0.05). Cows with one episode of mastitis produced more milk than those with repeated episodes of mastitis (P < 0.01). Increase in the number of mastitis episodes and also decrease in interval between first calving and mastitis increased services per conception (P<0.001). Mastitis episode and the interval between calving and first mastitis had no apparent impact on the calving to conception interval (P>0.05). Calving year, calving difficulty score, and cumulative first 60 days milk production had significant impacts on mastitis risk (P<0.05). The interval from calving to the first incidence of mastitis decreased over the period studied (P<0.001). Productive life tended to be decreased due to mastitis (P00.07). Survival analysis showed a significant difference between the lengths of productive life for cows with different intervals from calving to first mastitis (P<0.01). The results demonstrated that clinical mastitis between first calving and conception reduced production and reproduction performance with an increase in chance of culling.
