Anaplasma capra and A. phagocytophilum, two species of the family Anaplasmataceae, are zoonotic tick-borne obligate intracellular bacteria affecting wild and domestic ruminants, dogs, cats, horses and humans. A. capra and A. phagocytophilum infections have been steadily increasing in both number and geographic distribution, and the accurate diagnosis of these infections is challenging. This study aimed to develop a rapid, sensitive and reliable duplex real-time PCR assay for the specific detection and differentiation of these Anaplasma species...

Deficits in cognitive control have been found in depression, but how they contribute to depressive symptoms remains unknown. The present study investigated whether the regulatory efficacy of cognitive control on negative emotion varies with depression level and whether the regulatory efficacy affects depressive symptoms via the mediation of rumination. Fifty participants screened by the Zung Self-Rating Depressive Scale (SDS) with high and low depression levels were selected. They were instructed to controlled-process different semantic representations of aversive pictures, and the amplitude of the late positive potential (LPP) evoked by the pictures was used as the measure of electrocortical response...

BACKGROUND: Alopecia is defined as the partial or complete absence of hair from areas of the body where it normally grows. Alopecia secondary to an infectious disease or parasitic infestation is commonly seen in cattle. It can also have metabolic causes, for example in newborn calves after a disease event such as diarrhoea. In the article, the investigation of a herd problem of acquired alopecia in Belgian Blue (BB) crossbred calves is described. CASE PRESENTATION: Several BB crossbred calves had presented with moderate to severe non-pruritic alopecia in a single small herd located in Southern Germany...

Climate protection and other environmental concerns render it critical that diets and agriculture systems become more sustainable. Mathematical optimization techniques can assist in identifying dietary patterns that both improve nutrition and reduce environmental impacts. Here we review 12 recent studies in which such optimization was used to achieve nutrition and environmental sustainability aims. These studies used data from China, India, and Tunisia, and from 7 high-income countries (France, Finland, Italy, the Netherlands, Sweden, the United Kingdom, and the United States)...

Ujué Fresán, Joan Sabaté
To maintain planetary health, human activities must limit the use of Earth's resources within finite boundaries and avoid environmental degradation. At present, food systems account for a substantial use of natural resources and contribute considerably to climate change, degradation of land, water use, and other impacts, which in turn threaten human health through food insecurity. Additionally, current dietary patterns, rich in animal products and excessive in calories, are detrimental to both population and planetary health...

Although Streptococcus suis has attracted public attention as a major swine and human pathogen, this bacterium has also been isolated from other animals, including ruminants. However, recent taxonomic studies revealed the existence of other species that were previously identified as S. suis, and some of these isolates were reclassified as the novel species Streptococcus ruminantium. In Japan, biochemically identified S. suis is frequently isolated from diseased ruminants; however, such isolates have not yet been identified accurately, and their aetiological importance in ruminants is unclear...

BACKGROUND: The ureagenesis plays a central role in the homeostatic control of nitrogen metabolism. This process occurs in the liver, the key metabolic organ in the maintenance of energy homeostasis in the body. To date, the understanding of the influencing factors and regulators of ureagenesis in ruminants is still poor. The aim of this study was to investigate the relationship between energy metabolism and ureagenesis and detect the direct regulators of ureagenesis in the liver by using RNA-seq technology...

BACKGROUND: Co-existence of eating disorders and NSSI, suicide attempts and ideations is well established yet much is not known about the personality traits and behavioral tendencies that maintain this relationship. To this date no empirical work has been produced that offers a multifactorial view on the contributing variables to the occurrence of self-harm behaviors in EDs. METHOD: Binge eating, depression, impulsivity, ruminations and loss aversion were assessed in a sample of 93 patients diagnosed with Anorexia-Nervosa and Bulimia-Nervosa and other EDs with a history of NSSI and suicide attempts...

This research was carried out to quantify the effects of a range of variables on milk fat globule (MFG) size for a herd of Holstein-Friesian cows managed through an automatic milking system with year-round calving. We hypothesised that the overall variation in average MFG size observed between individual animals of the same herd cannot sufficiently be explained by the magnitude of the effects of variables that could be manipulated on-farm. Hence, we aimed to conduct an extensive analysis of possible determinants of MFG size, including physiological characteristics (parity, days in milk, days pregnant, weight, age, rumination minutes, somatic cell count) and milk production traits (number of milkings, milk yield, fat yield, protein and fat content, fat-protein ratio) on the individual animal level; and environmental conditions (diet, weather, season) for the whole herd...

BACKGROUND: Reports of a lack of efficacy of most of the anthelmintic compounds for ruminants associated with the long-time necessity for creating new molecules have stressed the urgency to adopt alternative methods to control gastrointestinal parasites infection, such as strategies of sharing grazing areas. Therefore, this study aimed to evaluate nematode populations affecting cattle and sheep that share grazing areas before and after treatment with different anthelmintic compounds, and investigate the efficacy of anthelmintic treatment in these naturally infected ruminants at farms in the state of Rio Grande do Sul, Brazil...

Ubiquitin-fold modifier 1 (UFM1)-specific ligase 1 (UFL1) is an important component of the UFM1 conjugation system, which is required for various cellular processes including protein translation, apoptosis, autophagy, and signal transduction. However, both, the expression of UFL1 in mammary cells and its role in endoplasmic reticulum (ER) stress in bovine mammary epithelial cells (BMECs) remain to be fully elucidated. Here, we characterized the potential roles of UFL1 in BMECs. Amino acid sequence comparison indicated that bovine UFL1 shares a high level of sequence identity with the UFL1 of other ruminant species...

The aim of the study was to evaluate the ruminal function and microbial community of lamb under different nutrient levels. Sixty-four lambs with similarity body weight were randomly assigned to four groups after weaning off ewe's milk on the 17th day (6.2 ± 0.2 kg). The lambs of the control group (CON) were fed a basal diet, and the other three groups were subjected to a diet of decreased protein (PR), digestible energy (ER) or both of them at 20% (BR) of basal diet. The decrease of dietary protein or energy level decreased the average daily gain, ruminal weight and mucosal thickness of lambs (P < 0...

Fibrobacter succinogenes S85, isolated from the rumen of herbivores, is capable of robust lignocellulose degradation. However, the mechanism by which it achieves this is not fully elucidated. In this study, we have undertaken the most comprehensive quantitative proteomic analysis, to date, of the changes in the cell envelope protein profile of F. succinogenes S85 in response to growth on cellulose. Our results indicate that the cell envelope proteome undergoes extensive rearrangements to accommodate the cellulolytic degradation machinery, as well as associated proteins involved in adhesion to cellulose and transport and metabolism of cellulolytic products...

Species distribution and composition of the ciliates found in the ruminal contents of 15 domestic sheep (Ovis aries) living in Kastamonu, Turkey, were investigated. Twenty-four species and 8 morphotypes belonging to 10 genera were identified. The density of the rumen ciliates in sheep was 108.2 (± 150.8) × 104 cells ml-1, and the mean number of ciliate species per host was 10.7 ± 4.6. Among the ciliate species identified, Dasytricha ruminantium was the most abundant, with a prevalence of 93.3%, whereas Diplodinium quinquespinosum, Eudiplodinium rostratum, and Metadinium tauricum were detected in only one animal (6...

Cranial weapons of all shapes and sizes are common throughout the animal kingdom and are frequently accompanied by the evolution of additional traits that enhance the use of those weapons. Bovids (cattle, sheep, goats, antelope) and cervids (deer) within the mammal clade Ruminantia are particularly well known for their distinct and varied cranial appendages in the form of horns and antlers, which are used as weapons in intraspecific combat between males for access to mates. Combat in these species takes many forms, including head-on collisions (ramming); stabbing an opponent's head or body with horn tips (stabbing); rearing and clashing downwards with horns (fencing); or interlocking antlers or horns while vigorously pushing and twisting (wrestling)...
