ABSTRACT Molecular characterization of isolates from staphylococcal food poisoning (SFP) outbreaks in Japan showed that the dominant lineage causing SFP is clonal complex 81 (CC81), a single-locus variant sequence type 1, coagulase VII, positive for sea and/or seb , and seh . Among various CC lineages producing enterotoxin A, CC81 highest toxin productivity.
This study investigates the potential of non-invasive, continuous temperature measurement techniques for assessing cattle welfare. We employed advanced object detection algorithms and infrared thermography to accurately extract continuously measure temperatures eyes muzzles 11 calves over several months (total, 33 samples). A mobile thermal imaging camera was paired with Mask R-CNN algorithm (object detection) trained on annotated datasets detect eye muzzle regions accurately. Temperature...
The aim of this study was to investigate the relationship between first ovulation within 3 weeks postpartum and subsequent ovarian cycles fertility in high producing dairy cattle Hokkaido, Japan. In Experiment 1, 110 cows (44 primiparous 66 multiparous) were used determine effects on cycles. Milk samples collected twice weekly from 7 100 days postpartum. identified by an increase milk progesterone (P4) more than 1 ng/ml numbers showing anovulation 31 (70.5%) 13 (29.5%) 35 (53.0%) (47.0%)...
To assess the relationship between pH and temperature in ruminal bottom fluid, circadian changes were monitored using cows fed a control diet (C diet) or rumen acidosis-inducing (RAI by wireless radio-transmission pH- measurement system. These two parameters measured simultaneously at 10-min intervals on day 14 after commencement of feeding. Compared to mean for 60 min immediately morning feeding (0 hr), significantly lower was noted 3–13 hr later (P<0.05) 4–19 (P<0.01) C RAI diets,...
This study was performed to clarify the analgesic effect of ketamine injected into first intercoccygeal (Co1-Co2) epidural space in standing cattle. Five adult cows were randomly received 3 treatments at least 1 week interval: 5, 10 and 20 mL 5% ketamine. Sedation, analgesia, ataxia other effects on cardiopulmonary rumen functions assessed before administration until 120 min. The analgesia without sedation shown tail perineum about 5 min after all three treatments. duration significantly...
Circadian pH changes in the fluid of rumen (bottom and middle) reticulum were assessed simultaneously using wireless wired radio-transmission pH-measurement systems cows fed a control diet (C diet) or rumen-acidosis-inducing (RAI diet). The three sites decreased following morning evening feedings. In C diet, bottom-rumen reticular reverted to basal level by next morning, while middle-rumen did not recover completely, suggesting that active fermentation occurred middle rumen. mean at 1 hr...
Laminar bone or primary plexiform tissue, not Haversian bone, shows an alternative concentric pattern of laminar-bone units plates around the marrow periphery long bones, although laminar is gradually replaced by osteons during growth period. One unit constructed with a hypercalcified line in center, woven on both sides line, and lamellar laminated appositional lines. Such showing homogeneous calcification has been reported young calves some large animals, but it foals previous report...
This study determined the appropriate biochemical assay for measuring plasma tartrate-resistant acid phosphatase isoform 5b (TRAP5b) activity; this information is important to clarify relationship between TRAP5b and known bone markers in cattle. When was measured using fluorometric spectrophotometric methods, hemolysis products did not affect former method. In from healthy cattle, there a good correlation (r=0.66) 2 methods. age-related profiles, (r=-0.53), hydroxyproline (HYP, r=-0.56)...
The present study was designed to assess the clinical usefulness of measurement urinary N-acetyl-β-D-glucosaminidase (NAG) activity and its isoenzymes in cats with disease. Thirty-five healthy 9 renal disease were used. Furthermore, a 5-year-old female cat administered large amount sulfonamide order induce acute failure, urine samples collected for assay NAG isoenzymes. Urinary measured using p-nitrophenyl N-acetyl-β-D-glucosaminide, expressed as units per gram creatinine (NAG index)....
We examined fluctuations in plasma tartrate-resistant acid phosphatase isoform 5b (TRAP5b) measured using fluorometry conjunction with those calcium (Ca) and other bone metabolic markers from 2 weeks prepartum to postpartum 7 primiparous 18 multiparous pregnant cows. The Ca concentration decreased temporarily on the day of calving cows only. Plasma TRAP5b peaked was significantly lower than before after parturition. hydroxyproline increased 1 week Bone-specific alkaline osteocalcin tended...
Although a molecular diagnostic assay using clinically accessible tissue, such as blood, would facilitate evaluation of disease conditions in humans and animals, little information exists on microarray-based gene expression profiling circulating leukocytes from hypocalcemic cows. Therefore, peripheral blood mononuclear cells dairy cows with experimentally induced hypocalcemia or spontaneous milk fever were subjected to oligo-microarray analysis identify specific biomarker genes. In...
To evaluate diurnal variation of plasma bone markers, blood samples were collected from five calves at 2-hr intervals throughout a 24-hr period. Tartrate-resistant acid phosphatase isoform 5b (TRAP5b), carboxy-terminal collagen crosslinks type-I (CTX), hydroxyproline, specific alkaline (BALP) and osteocalcin measured. Cosinor analysis showed significant rhythm in all markers. The acrophase each marker appeared the early to late morning. percentage ratio amplitude mesor within-subject...
The purpose of this study was to elucidate the colostral and foal serum immunoglobulin G (IgG) concentration values in heavy draft horses Japan examine effects peripartum mare condition on immunity. Colostrum obtained 1 hr after foaling (pre-suckling; n=178). Blood collected from jugular vein foals (n=147) at 24 48 birth. statuses 73 mares were recorded. average IgG 10,540 ± 3,190 mg/dl (median=10,928; range 1,434−17,514 mg/dl). neonatal birth 1,750 919 (median=1,890; 0−3,510 Although did...
