Bulk tank milk samples from 392 Northern Ireland dairy farms and individual animals (n = 293) on 4 of these were tested by a novel phagomagnetic separation (PhMS)-quantitative (q)PCR assay able to detect quantify viable Mycobacterium avium ssp. paratuberculosis (MAP), demonstrate its potential utility as surveillance tool. Viable MAP detected in 26.5% the bulk milks, with contamination levels r...

The objective of this study was to examine the relationship between monthly Dairy Herd Improvement (DHI) subclinical mastitis and new infection rate estimates and daily bulk tank somatic cell count (SCC) summarized by statistical process control tools. Dairy Herd Improvement Association test-day subclinical mastitis and new infection rate estimates along with daily or every other day bulk tank ...

In investigations on slow acid development by lactic acid starter cultures,2 only limited consideration has been given to the effect of other bacteria present in the raw milk. Attention has been directed to inhibitory effects of such substances as nisin produced by certain streptococci and to possible inhibition by other bacteria (Cox and Whitehead, 1931; Babel, 1955). However, little specific ...

The objectives of this study were (i) to describe staphylococcal isolates recovered from bulk-tank raw milk collected sheep and goat farms during a countrywide performed in Greece, (ii) management factors potentially associated with their presence (iii) provide evidence regarding association the quality milk. In total, 312 isolates, samples 444 small ruminant evaluated work. vitro formation bio...

In this study 130 bulk tank milk samples which were delivered to the Pegah Pasturisation Factory inMashhad were collected randomly during the summer months. Samples were firstly enriched in modifiedtrypticase soy broth containing novobiocin, followed by plating onto sorbitol MacConkey agar supplementedwith cefixime and potassium tellurite for isolation of Escherichia coli O157:H7. Consequently ...

the potential of bulk starter fermentation strategy for production of a cost-effective and safe source of β-galactosidase was investigated. three different bulk starter media with different compositions were selected, and an industrial yogurt starter culture strain, l. bulgaricus dsm 20081 was cultivated in these media under ph-controlled conditions (ph=5.6) at 43°c. the media consisted of 1) b...

BACKGROUND Mycoplasma bovis is an important pathogen causing severe disease outbreaks in cattle farms. Since 2011, there has been an apparent increase in M. bovis outbreaks among Danish dairy cattle herds. The dairy cattle industry performed cross-sectional antibody screening for M. bovis on four occasions, using the indirect BIO K 302 M. bovis enzyme-linked immunosorbent assay (ELISA) (Bio-X, ...
