Use of inline measures of l-lactate dehydrogenase for classification of posttreatment mammary Staphylococcus aureus infection status in dairy cows

Abstract: An automated method for determining whether dairy cows with subclinical mammary infections recover after antibiotic treatment would be a useful tool in dairy production. For that purpose, inline l-lactate dehydrogenase (LDH) measurements was modeled using a dynamic linear model; the variance parameters were estimated using the expectation-maximization algorithm. The method used to classify cows as infected or uninfected was based on a multiprocess Kalman filter. Two learning data sets were created: infected an… Show more

“…The highest DE expressed genes in the mastitic group were β-2microglobulin (B2M), CD74 molecule (CD74), major histocompatibility complex class II DR α (BoLA-DRA), serine dehydratase (SDS), and l-lactate dehydrogenase A chain (LDHA; Table 2). When an inflammatory process involving cell damage occurs, LDH is released from cells into the milk (Jørgensen et al, 2016); therefore, LDH activity increases with mastitis (Bogin et al, 1977;Harmon, 1994). This evidence supports the high expression values of LDHA gene in the SC milk samples from mastitic quarters.…”

“…Pyruvate is converted into L‐lactic acid by L‐lactate dehydrogenase (EC 1.1.1.27, 1.17‐fold) and into 2‐hydroxyethyl‐ThPP by pyruvate dehydrogenase (acetyl‐transferring) E1 (EC 1.2.4.1, 0.67‐fold). L‐lactate dehydrogenase catalyses the conversion of pyruvate into L‐lactate acid (Jørgensen et al ., 2016). Pyruvate enters into the citrate cycle through the pyruvate dehydrogenase.…”

“…Denmark) was used in combination with a DeLaval milking robot (DeLaval Inc., Tumba, Sweden). The Herd Navigator™ is programmed to collect milk samples automatically and analyze mP4 in individual cows through a dry-stick biosensor technology and enzyme immunoassay [19], based on a bio-model that establishes frequency and quantification of mP4 samples. The system modulated the frequency of assays at an average of six to seven progesterone analyses per cycle according to the postpartum period and the stage of the estrous cycle.…”
