The objective of my research was to generate novel information concerning the epidemiology, diagnosis and prevention of bovine respiratory disease complex (BRDC), a common pre-weaning and post-weaning beef calf disease. To reach my objective, I conducted three prospective field trials within post-weaned calf populations, and one retrospective study of pre-weaned calves utilizing survey data. I evaluated differences in behavior, health and performance in calves receiving multiple component health programs. Calves in a minimally invasive program, which included primarily non-injectable products, displayed less aversion to initial product administration but experienced higher BRDC morbidity (P = 0.02) and poorer performance (P = 0.04) compared to calves in a more invasive (all injectable products) program. Secondly, in a study of Mannheimia haemolytica inoculated calves, I found that no parameter included in physical examinations, or common blood component evaluations could discern health from ...

Bovine respiratory disease (BRD) is the most important cause of clinical disease and death in feedlot cattle. Respiratory viral infections are key components in predisposing cattle to the development of this disease. To quantify the contribution of four viruses commonly associated with BRD, a case-control study was conducted nested within the National Bovine Respiratory Disease Initiative project population in Australian feedlot cattle. Effects of exposure to Bovine viral diarrhoea virus 1 (BVDV-1), Bovine herpesvirus 1 (BoHV-1), Bovine respiratory syncytial virus (BRSV) and Bovine parainfluenza virus 3 (BPIV-3), and to combinations of these viruses, were investigated.. Based on weighted seroprevalences at induction (when animals were enrolled and initial samples collected), the percentages of the project population estimated to be seropositive were 24% for BoHV-1, 69% for BVDV-1, 89% for BRSV and 91% for BPIV-3.. For each of the four viruses, seropositivity at induction was associated with ...

Chronic endemic respiratory disease of dairy calves and an important component of bovine respiratory disease complex. It primarily affects calves up to six months of age and the etiology is multifactorial. Stress plus a primary viral infection is followed by a secondary bacterial infection. The latter is most commonly associated with PASTEURELLA MULTOCIDA producing a purulent BRONCHOPNEUMONIA. Sometimes present are MANNHEIMIA HAEMOLYTICA; HAEMOPHILUS SOMNUS and mycoplasma species.
The cost of Bovine Respiratory Disease to the beef industry due to death, poorer conversions, and therapy is estimated to cost more than $3 billion per year. Identifying and mitigating Bovine Respiratory Disease in cattle can be difficult due to the increased susceptibility for Bovine Respiratory Disease in high risk cattle. One management option to minimize an outbreak of respiratory disease is the use of metaphylaxis, the mass treatment of a group of calves to reduce the incidence and adverse effects of respiratory disease on high risk animals. Criteria used to determine the necessity of metaphylactic treatment against Bovine Respiratory Disease in feedlots can be based on several factors depending on feedlot preference; however, the primary criteria often considered are: a known history of no previous vaccinations, overall appearance of cattle, source of cattle, Bovine Respiratory Disease in calves received from same source previously, long shipping distance, season of the year, and light arrival
Respiratory syncytial virus (RSV) is the most common viral cause of childhood acute lower respiratory tract infections. It is estimated that RSV infections result in more than 100,000 deaths annually worldwide. Bovine RSV is a cause of enzootic pneumonia in young dairy calves and summer pneumonia in nursing beef calves. Furthermore, bovine RSV plays a significant role in bovine respiratory disease complex, the most prevalent cause of morbidity and mortality among feedlot cattle. Infection of calves with bovine RSV shares features in common with RSV infection in children, such as an age-dependent susceptibility. In addition, comparable microscopic lesions consisting of bronchiolar neutrophilic infiltrates, epithelial cell necrosis, and syncytial cell formation are observed. Further, our studies have shown an upregulation of pro-inflammatory mediators in RSV-infected calves, including IL-12p40 and CXCL8 (IL-8). This finding is consistent with increased levels of IL-8 observed in children with RSV
Ned F. Kuehn, DVM, Diplomate, ACVIM. Feline respiratory disease complex includes those illnesses typified by rhinitis, conjunctivitis, lacrimation, salivation, and oral ulcerations. The principal diseases, Feline Viral Rhinotracheitis (FVR) and Feline Calicivirus (FCV) infections, affect exotic as well as ~domestic species. Feline Pneurnonitis (Chlamydia psittaci) and Mycoplasmal infections ,appear to be of lesser importance. Feline infectious peritonitis and pleuritis typically causes a more generalized condition but may cause signs of mild upper respiratory tract infection. I FVR and calliciviruses are host-specific and pose no known human risk. Human conjunctivitis caused by the feline chlamydial agent has been reported.. Etiology: Probably 40-45% of feline upper respiratory infections are caused by FVR s , which is a herpesvirus; incidence of FCV is similar. Dual infections with these viruses are common. Other organisms such as Chlamydia psittaci, Mycoplasma spp, and reoviruses are believed ...
... Cattle producers are fully aware of the expenses that go into herd management - feeding, housing, transporting and marketing - and perhaps most important, overall health care.
Bovine respiratory disease (BRD) accounts for up to 70 percent of health disruptions and $500 million in associated medical costs and production losses, thus receiving considerable attention from cattle health personnel in production and research alike. Experiments were conducted in 2 studies to investigate aspects of nutrition and animal health in receiving cattle. Blood chemistry and immune components of sick and healthy cattle, along with feed intake, growth, and feed efficiency were evaluated for methods potentially useful in BRD diagnosis or offsetting performance losses. Intake, blood chemistry analysis, and immune proteins known as acute phase proteins provided patterns with possible complementarity for more accurate objective BRD diagnosis. Feed efficiency was improved by supplementing amino acids to exceed nutrient requirements. Utilizing these findings could provide incremental improvements in the current stalemate against BRD, improving both beef industry profitability and animal ...
The therapeutic efficacy of an early treatment protocol with an infection-stage adjusted fluoroquinolone regimen was evaluated in a field study on Young Bulls (YB) presenting signs of Bovine Respiratory Disease (BRD). A total of 195 YB (Charolais, Limousin and Rouge-des-Prés breeds) from 6 farms implementing or not prophylactic antimicrobial treatments (PROPHY or absence) were randomly assigned to one of two experiment groups based on time of detection of BRD and first line marbofloxacin regimen, early adjusted dose (E2) or late standard dose (L10). Each YB was administered orally a reticulo-rumen bolus, allowing continuous monitoring of ruminal temperature. In the E2 group, YB presenting early signs of BRD, i.e. an increase in ruminal temperature over 40.2 °C and persisting more than 12h, confirmed by a clinical examination showing no or mild signs of BRD, were given 2 mg/kg of marbofloxacin. In the L10 group, YB presenting moderate or severe signs of BRD at visual inspection, confirmed at clinical
Background Bovine respiratory disease (BRD) is caused by growth of single or multiple species of pathogenic bacteria in lung tissue following stress and/or viral infection. Next generation sequencing of 16S ribosomal RNA gene PCR amplicons (NGS 16S amplicon analysis) is a powerful culture-independent open reference method that has recently been used to increase understanding of BRD-associated bacteria in the upper respiratory tract of BRD cattle. However, it has not yet been used to examine the microbiome of the bovine lower respiratory tract. The objective of this study was to use NGS 16S amplicon analysis to identify bacteria in post-mortem lung and lymph node tissue samples harvested from fatal BRD cases and clinically healthy animals. Cranial lobe and corresponding mediastinal lymph node post-mortem tissue samples were collected from calves diagnosed as BRD cases by veterinary laboratory pathologists and from clinically healthy calves. NGS 16S amplicon libraries, targeting the V3-V4 region ...

Ultimately, a mixture of disease organisms is usually responsible for the respiratory infection and illness, but a number of other factors influence the animals ability to withstand the infection and illness. Any one risk factor alone may be insufficient to trigger cases of BRD, but together they form an additive effect that can predispose the animal to BRD.. Environmental factors, particularly transport, have been associated with BRD for decades. Therefore, BRD may also be referred to as Shipping Fever. A study involving calves arriving at 21 US commercial feedlots from 1997 to 2009 concluded that distance traveled was correlated to BRD, average daily gain (ADG) and hot carcass weight (HCW). This, however, has not been substantiated in western Canada.. Weather has always been implicated in the occurrence of BRD, presumably because the greatest incidence of BRD occurs during the fall. However, this finding is confounded by the fact that it is also when the greatest number of calves is being ...

Respiratory Disease Complex or Multicausal in Laying Hens. Happenings / Clinical Signs. Although much is known about the individual agents responsible for respiratory diseases in poultry, uncomplicated infections with single agents are the exception. Under commercial conditions, complicated infections involving multiples aetiologies with viruses, mycoplasmas and other bacteria, immunosuppressive agents, and unfavourable environmental conditions are more commonly observed than simple infections. In addition, respiratory reactions induced by routine vaccination programs may themselves play a major role in the development of respiratory disease.. Mortality. ...

Treating any one of these symptom-causing organisms may help the body function better and lighten the viral load. As one ME patient has said, its like carrying around a backpack of rocks. If you treat one virus successfully, its like tossing out one of the rocks. But lightening the load is not treating the whole disease complex. It does not remove the effect of that second circle; it simply makes it less. ...

Bovine respiratory syncytial virus (BRSV) is the principal aetiological agent of the bovine respiratory disease complex. A BRSV subunit vaccine candidate consisting of two synthetic peptides representing putative protective epitopes on BRSV surface glycoproteins in soluble form or encapsulated in poly(lactide-co-glycolide) (PLG) microparticles were prepared. Calves (10 weeks old) with diminishing levels of BRSV-specific maternal antibody were intranasally administered a single dose of the different peptide formulations. Peptide-specific local immune responses (nasal secretion IgA), but not systemic humoral (serum IgG) or cellular responses (serum IFN-γ), were generated by all forms of peptide. There was a significant reduction in occurrence of respiratory disease in the animals inoculated with all peptide formulations compared to animals given PBS alone. Furthermore no adverse effects were observed in any of the animals post vaccination. These results suggest that intranasal immunisation with ...
Bovine Respiratory Disease (BRD) is the leading cause of calf death after weaning. Boehringer Ingelheim takes a holistic approach when helping producers fight the disease, said Professional Services Veterinarian Dr. Rich Linhart.. "We look at everything on the ranch, from personnel to feed bunk space to mud to wind to the way pens are set up, and cattle flow," said Linhart, who is based in Boise, Idaho.. He said the company does offer both vaccines and antibiotics to help prevent and battle BRD, but also recognizes the importance of good nutrition and many other factors when it comes to keeping the disease off the farm or ranch. Linhart answered questions from producers at the 2018 Cattle Industry Convention and National Cattlemens Beef Association Trade Show in Phoenix..

Recent studies have shown that major grapevine viruses for the Mediterranean region are prevalent in the native cultivars that have been grown for long in Albanian vineyards. Infectious Degeneration disease complex caused by Grapevine Fan Leaf Virus (GFLV), and other viruses, comprises a common phenotype in the field, but GFLV detection in random samplings has shown low frequency. In the present study we aimed at evaluating the association between Infectious Degeneration phenotype in the field and GFLV in the native cultivar Kallmet, by using DAS-ELISA of extracts from lignified canes of symptomatic plants. The results showed that Infectious Degeneration phenotype is widely spread but only 20% of the tested symptomatic plants were found positive for GFLV indicating that other viruses involved in the disease complex may account for the phenotype in the field. It is suggested that the full set of viral agents involved in Infectious Degeneration disease complex be tested to understand their ...
Julie Elkins and Paul Burr advocate a holistic approach to assessing respiratory disease risk factors and consider housing, management and treatment options.
Background: Mannheimia haemolytica is the primary bacterial pathogen in causing bovine respiratory disease with tremendous annual losses in the cattle industry. The leukotoxin from M. haemolytica is the predominant virulence factor. Several leukotoxin activity assays are available but not standardized regarding sample preparation and cell line. Furthermore, these assays suffer from a high standard error, a prolonged time consumption and often complex sample pretreatments, which is important from the bioprocess engineering point of view. Results: Within this study, an activity assay based on the continuous cell line BL3.1 combined with a commercial available adenosine triphosphate viability assay kit was established. The leukotoxin activity was found to be strongly dependent on the sample preparation. Furthermore, the interfering effect of lipopolysaccharides in the sample could be successfully suppressed by adding polymyxin B. We reached a maximum relative P95 value of 14%, which is more than ...

Feedlot or intensive finishing environments present significant animal health challenges due to a large number of livestock being confined to a relatively small area. The more pathogens that livestock can be exposed to before the feedlot or intensive finishing system entry, the more likely they are to mount a successful immune response to a challenge once on feed.. Backgrounding plays an important role in minimising health issues once in the feedlot or intensive finishing system by allowing livestock to interact, experience low levels of contagions and develop immunity.. Viral infections such as Pesti Virus and Infectious Bovine Rhiotracheitis are extremely contagious but generally cause only mild signs in young stock. However, they cause marked transient immuno-suppression during the viraemia and this allows more serious pathogens to establish. This is particularly important for conditions such as bovine respiratory disease which is caused by bacterial pathogens that are commonly found in the ...

Some predisposing factors play a large part when it comes to this category of diseases, and the good news is they can be ...
The long-term effects of a single dose of meloxicam (Metacam 20mg/ml; Boehringer Ingelheim Vetmedica) in conjunction with antibiotic therapy in cattle with clinical signs of bovine respiratory disease (BRD) was evaluated in a blind, controlled, randomised study. Two hundred animals with clinical signs of BRD received a single subcutaneous injection of 20 mg/kg oxytetracycline; 100 of them also received a subcutaneous injection of 0·5 mg/kg meloxicam, and the other 100 received an injection of isotonic saline. The animals were weighed before they were treated and seven, 35, 70 and 105 days later, and finally before they were slaughtered. The mean bodyweight of the meloxicam-treated animals was significantly higher from day 70 until slaughter, and the mean average daily weight gain until slaughter and the mean carcase weight of the animals treated with meloxicam were significantly higher. In the animals with lung lesions, significantly less lung tissue was affected in those that had been treated ...
