Mycoplasma bovis is associated with pneumonia in calves characterized by the development of chronic caseonecrotic lesions with the agent persisting within the lesion. The purposes of this study were to characterize the morphology of lung lesions, examine the presence of M. bovis variable surface protein (Vsp) antigens and study the local immune responses in calves after infection with M. bovis strain 1067. Lung tissue samples from eight calves euthanased three weeks after experimental infection with M. bovis were examined by bacteriology and pathology. Lung lesions were evaluated by immunohistochemical (IHC) staining for wide spectrum cytokeratin and for M. bovis Vsp antigens and pMB67 antigen. IHC identification and quantitative evaluation of CD4+ and CD8+ T lymphocytes and immunoglobulin (IgG1, IgG2, IgM, IgA)-containing plasma cells was performed. Additionally, expression of major histocompatibility complex class II (MHC class II) was studied by IHC. Suppurative pneumonic lesions were found in all

MPI continues to build the picture of where the cattle disease Mycoplasma bovis is present and contain it to those farms.. The Ministry is working to assure farmers with properties in the vicinity of the affected Van Leeuwen Dairy Group farms that the control measures in place are sufficient to prevent the spread of the disease.. Ministry Director of Response Geoff Gwyn says the main way the disease can spread is through direct contact between cattle, such as nose to nose.. "All the other potential factors such as on equipment, clothing and footwear, effluent and vehicles present a comparatively low risk.. "We encourage farmers to pay attention to what are routine biosecurity measures such as on-farm hygiene, caution around stock movements and fencing stock back from neighbouring fence lines.. "It is natural for people to be worried, especially those directly affected and living close by - but we dont want people to be unnecessarily concerned.". Mr Gwyn says MPI is holding a further community ...
LIC, the countrys largest supplier of dairy genetics, will test its artificial breeding bulls for Mycoplasma bovis to provide its farmers with greater peace of mind through the dairy mating season.
The report is devoted to an analysis of the results of a complicated and dynamic examination of the ventilation apparatus in eighty-five patients having chronic pneumonia. The patients were examined both in a state of rest after performing an assigned physical task, and after inhaling ephedrine. The conclusions drawn from these studies are as follows: (1) There is a relationship between the functional condition of the ventilation apparatus and the clinically determined severity of respiratory failure: definite functional disturbances in a series of indices (MVL, VCL, pneumotachometric data, FVCL, frequency and depth of respiration) correspond to the degree of respiratory failure. (2) In chronic pneumonia, even during the early stages of development, there are disturbances of the bronchial permeability. (3) Dyspnea is not the first sign of respiratory failure. Even before it occurs, some functional disorders of the ventilation apparatus become manifest in chronic pneumonia patients (reduction of MVL

Good on-farm biosecurity and accurate tracing of animal movement is not an option in todays world, its an imperative, Federated Farmers President Katie Milne said.. Positive tests for Mycoplasma bovis in herds in Hastings and Winton (Southland) and a suspected case in Ashburton further underline the need for farmers to treat biosecurity measures on their own properties as a top priority.. Federated Farmers and other industry leaders remain committed to eradicating Mycoplasma bovis, even though the announcement makes that a bigger but by no means impossible challenge, Katie said.. "Dont rely on others to protect your patch, protect it yourself. In the end, we are all biosecurity officers with a role to play.". Establishing a 1.5m buffer along fence lines with neighbouring properties should be standard practice. Where practical that could be a vegetation buffer, which would deliver biosecurity and biodiversity benefits. Close and repeated contact with an infected animal is still regarded as the ...
The phosphoenolpyruvate (PEP)-dependent phosphotransferase system (PTS) is a major mechanism used by bacteria for uptake of carbohydrates, particularly hexoses, hexitols, and disaccharides, where the source of energy is from PEP. The PTS consists of two general components, enzyme I (EI) and histidine phosphocarrier protein (HPr), and of membrane-bound sugar specific permeases (enzymes II). Each enzyme II (EII) complex consists of one or two hydrophobic integral membrane domains (domains C and D) and two hydrophilic domains (domains A and B). EII complexes may exist as distinct proteins or as a single multidomain protein. The PTS catalyzes the uptake of carbohydrates and their conversion into their respective phosphoesters during transport. There are four successive phosphoryl transfers in the PTS. Initial autophosphorylation of EI, using PEP as a substrate, is followed by transfer of the phosphoryl group from EI to HPr. EIIA catalyzes the self-phosphoryl transfer from HPr after which the ...

Crossbred yearling heifers (n = 394) were used to compare the effect of high or low blood glucose measured at arrival on feedlot performance and carcass characteristics. A blood sample was collected when heifers arrived at the Beef Cattle Research Center, and heifers were sorted into two groups: high or low blood glucose. The mean blood glucose concentration of the heifers was 57 ± 2 mg/dL in the low group and 78 ± 2 mg/dL in the high group. Heifers that had low blood glucose at arrival consumed more feed (P=0.02), tended to have increased final bodyweight and rate of gain (P,0.10), had increased backfat thickness (P,0.05), and tended to have heavier hot carcass weights and fewer standard carcasses (P,0.10) compared with heifers that had high blood glucose at arrival ...
Mycoplasma bovis (M. bovis) is a highly contagious pathogen and M. bovis-associated diseases, particularly pneumonia, occur predominantly as herd enzootics, causing considerable economic losses because of calf mortality, weight loss in surviving calves. In our previous studies, the programmed death-1(PD-1)/ PD-ligand 1 (PD-L1) pathway and prostaglandin E2 (PGE2) were shown to be involved in the immunosuppression during chronic infectious diseases in cattle. In this study, the efficacy of dual blockade of the PD-1/PD-L1 pathway and PGE2 in M. bovis infection in vivo was investigated using anti-bovine PDL1 rat-bovine chimeric antibody, Boch4G12, and cyclooxygenase 2 (COX-2) inhibitor, meloxicam. The calves treated with Boch4G12 and meloxicam significantly enhanced M. bovis-specific IFN-γ response after the administration. On the other hand, IFN-γ response was not activated in the controls and cattle treated with meloxicam alone throughout the experimental period. Interestingly, bacterial loads ...

Too much Stephen Colbert stopping recording for a time. The monologue the best bit. The rest not so much. Mycoplasma bovis. Good decision.
The significant genome compaction in mycoplasmas was made possible by adoption of a parasitic lifestyle. During their evolution and adaptation to a parasitic mode of life the mycoplasmas have developed various genetic systems enabling their attachment to host tissues as well as a highly plastic set of variable surface proteins. The generation of a versatile surface coat through high-frequency phase and size variation provides the organism with a useful tool for immune system avoidance, allowing the mycoplasmas to escape antibody attack, explaining why these minute organisms are such successful parasites. ...

Hi ladies. My son was a 27 weeker that weighed 1 pound 12 ounces. He was on a vent/ocillator for a few weeks. Due to that, he has some lung damage. This is his 2nd time with pneumonia in 2 years. Both required a trip to the hospital-one with an overnight stay. Is this going to be a chronic thing? He uses a neublizer only when he has a bad uri or cold. We were not able to see our regular ped as he had the week off and didnt really think to ask the doc we saw as I was tired and flustered. What have you experienced? Any advice or suggestions would be greatly appreciated ...

Differential uptake and utilization of carbon sources in M. bovis and M. gallisepticum.Our comparative metabolite profiling and [13C]glucose-labeling studies with M. gallisepticum and M. bovis highlighted clear differences in the way each of these bacteria catabolizes glucose (14, 16). Specifically, M. gallisepticum actively takes up exogenous glucose and accumulates large intracellular pools of hexose phosphate, indicating operation of the PTS glucose and carbohydrate transporter systems (17). These sugar phosphates are subsequently catabolized in the glycolytic and PPP, generating ATP and reducing equivalents, respectively. In contrast, M. bovis appears to primarily generate phosphorylated sugars via gluconeogenesis, even when exogenous glucose levels are high. These bacteria can take up glucose and other neutral sugars (Table S1; Fig. 4), possibly via the nonspecific carbohydrate ABC transporter CUT-2 (Table S2). Somewhat unexpectedly, steady-state analyses demonstrated glucose and fructose ...
The European bison (Bison bonasus), now found in Europe and the Caucasus, has been proposed to originate either from the extinct steppe/extant American bison lineage or from the extinct Bison schoetensacki lineage. Bison schoetensacki remains are documented in Eurasian Middle Pleistocene sites, but their presence in Upper Pleistocene sites has been questioned. Despite extensive genetic studies carried out on the steppe and European bison, no remains from the fossil record morphologically identified as Bison schoetensacki has been analyzed up to now. In this paper, we analyzed a 36,000-year-old Bison schoetensaki bone sample from the Siréjol cave (France) and a cave hyena coprolite (fossilized feces) found in a nearby cave and containing large amounts of Bovinae DNA. We show that the Bovinae mitochondrial DNA sequences from both samples, including a complete mitochondrial genome sequence, belong to a clade recently reported in the literature. This clade only includes ancient bison specimens without
The largest extant representative of the bovids, a diverse and well-known family, is the Asian forest-dwelling gaur (Bos gaurus), in which bulls can weigh up to 1,500 kg (3,300 lb), 4.5 m (15 ft) in total length and stand 2.2 m (7.2 ft) at the shoulder.[7][8] The living American Bison (Bison bison) of North America 2 to 3.5 m (6.6 to 11.5 ft) long, the tail adding 30 to 91 cm (12 to 36 in). Shoulder heights in the species can range from 152 to 201 cm (60 to 79 in).[9] Weights can range from 318 to 1,000 kg (701 to 2,205 lb).[10][11] The heaviest wild American bull ever recorded weighed 1,270 kg (2,800 lb).[12] The European bison (Bison bonasus) may be less heavy than the American species,[9] but would exceed heights at withers with the tallest record of 210 cm (83 in).[13] When raised in captivity and farmed for meat, the bisons can grow unnaturally heavy and the largest semidomestic American bison weighed 1,724 kg (3,801 lb) [10] and the heaviest European bison weighed about 1,900 kg (4,200 ...

Fifteen genes were shown to be enriched in 15 metabolic pathways, and they included the aforementioned genes encoding pyruvate kinase, transketolase, enolase, and L-lactate dehydrogenase. Hydrogen peroxide (H2O2) production in strains representing seven passages from P1 to P180 decreased progressively with increasing numbers of passages and increased attenuation. However, eight mutants specific to eight individual genes within the 14.2-kb deleted region did not exhibit altered H2O2 production. These results enrich the genomics database, and they increase our understanding of the mechanisms underlying virulence. is a member of the family in the class ...
American bison are North Americas largest terrestrial animals. Millions once roamed the grasslands and prairies of the Great Plains, but today the bison population survives primarily in conservation herds.
The European bison and the American bison are closely related and can interbreed without any fertility problems. Because of this, several authors treated them as one species in the past. Phenotypic differences are apparent; the American bison has a more longish and massive body, more opulent fur on the head forelegs and also the horns are not as long but thicker as in the Wisent, among other differences. However, both species are ecologically similar, except that grasses make up a higher portion in the diet of the American bison. The Wood bison, B. b. athabascae, inhabits a similar habitat as the Wisent did in ancient Europe. In 1940, hybrids of American and European bison were released in the Caucasus. After controlled culling and subsequent replacement with pure wisents, the portion of American blood within the Caucasus population is now estimated being only about 5%, although the American influence is still slightly visible in the phenotype of the animals. Allegedly this population has a ...
Bison adjust their diet seasonally based on reduced availability of the grasses they perfer but are less nutritious during the spring and fall.
BRONCHIECTASIS (Gr. βρόγχια, bronchial tubes, and ἒκτασις, extension), dilatation of the bronchi, a condition occurring in connexion with many diseases of the lungs. Bronchitis both acute and chronic, chronic pneumonia and phthisis, acute pneumonia and broncho-pneumonia, may all leave after them a bronchiectasis whose position is determined by the primary lesion. Other causes, acting mechanically, are tracheal and bronchial obstruction, as from the pressure of an aneurism, new growth, &c. It used to be considered a disease of middle age, but of late years Dr Walter Carr has shown that the condition is a fairly common one among debilitated children after measles, whooping cough, &c. The dilatation is commonly cylindrical, more rarely saccular, and it is the medium and smaller sized tubes that are generally affected, except where the cause is mechanical. The affection is usually of one lung only. Emphysema is a very common accompaniment. Though at first the symptoms somewhat ...
