“…The majority of these lesions, liver abscesses in particular, are sequela related to rumenitis/abomasitis which are caused by ruminal acidosis (Gudmundson et al 1978, Nagaraja & Lechtenberg 2007, Vechiato et al 2011, Constable et al 2017. However, concurrent diseases to CVCT such as mastitis, metritis, and phlebitis were observed in the current study and cannot be discarded as a potential cause of the primary focus of CVCT (Mohamed et al 2004, Plaizier et al 2008, Wilkins & Woolums 2015.…”

“…These signs, also reported by Motta et al (2016) characterize the classic form of CVCT and are most widely observed in the terminal stage of the disease (Mills & Pace 1990, Mohamed et al 2004, Peek & Divers 2018. Sudden death and acute respiratory distress can occur (Selman et al 1974, Braun 2008, Wilkins & Woolums 2015, Peek & Divers 2018. The abdominal enlargement observed in one animal, in the present study, is consistent with the mild ascites observed in another's paper (Braun et al 1992, Braun 2008.…”

“…The caudal vena cava thrombosis (CVCT) is a disease of low occurrence, but well described in cattle (Braun et al 2002, Wilkins & Woolums 2015. It is most commonly associated with rumenitis and/or abomasitis, favoring bacteria to reach the hepatic portal system, which may lead to formation of liver abscesses (Nagaraja & Lechtenberg 2007, Peek & Divers 2018, and subsequently, depending on the proximity of the abscesses to the caudal vena cava to thrombi in this vessel.…”

The formation of these thrombi may also be the consequence of other septic conditions, such as phlebitis, mastitis, metritis, traumatic reticulitis, omphalophlebitis, and pododermatitis (Gudmundson et al 1978, Plaizier et al 2008, Wilkins & Woolums 2015.…”

This paper aimed to describe the main clinico-epidemiological, laboratory, and anatomopathological findings in 10 cattle affected with caudal vena cava thrombosis. The main clinical signs observed were decreased milk production, reduced appetite, apathy, impairment of ruminal motility, cardiorespiratory disorders (tachycardia and tachypnea), epistaxis, hemoptysis, and ascites. Intercurrent diseases such as mastitis, metritis, and phlebitis were verified. The hematological findings were mild anemia, leukocytosis due to neutrophilia with regenerative left shift, and hyperfibrinogenemia. The pathological exams revealed thrombi in the caudal vena cava, hepatomegaly, ascites, liver abscesses, pulmonary edema and emphysema, and abscesses in the lungs. The association of epidemiological information, clinical signs such as respiratory distress, epistaxis or hemoptysis, in addition to anemia and leukocytosis due to neutrophilia, as well as the occurrence of thrombus in the caudal vena cava as pathological findings, are indicative elements of the clinical picture of vena cava thrombosis in cattle. It is reiterated that this disease has an unfavorable prognosis and, when diagnosed, the animal must be culled.

“…Control is achieved by modified live or inactivated virus vaccines. Morbidity tends to be high (prevalence of antibodies in the US ranges from 60-80 %) and mortality rate spans from none to 20 % [4,5]. Parainfluenza virus type 3 (PI3V) is also a paramyxovirus that is widely spread in cattle and other ruminant populations, which by itself causes subclinical to mild respiratory signs.…”

Animal welfare and economic implications of infectious diseases in cattle demand an efficient surveillance as the foundation for control and eradication programmes. Bovine respiratory syncytial virus (BRSV), Parainfluenza virus type 3 (PI3V), Bovine herpes virus-1 (BoHV-1), Bovine viral diarrhoea virus (BVDV), and Enzootic bovine leukosis virus (EBLV) cause common and often underdiagnosed diseases in cattle that are endemic in most countries []. A hallmark of individual exposure to a viral pathogen is the presence of antibodies directed towards that virus. The aim of this study was to develop and validate a pentaplex assay to simultaneously detect and quantify antibodies against BRSV, PI3V, BoHV-1, BVDV and EBLV in serum, as an efficient tool to yield epidemiological data. Monoplex assays were initially developed using either complete BRSV or BoHV-1 viral lysates, or recombinant proteins for BVDV, EBLV or PI3V as capture antigens. In addition, 125 serum samples from unvaccinated cattle, which were classified as positive or negative for each of the viruses by commercial ELISA kits, were used for validation. Conditions established for the Luminex monoplex assays were adopted for the pentaplex assay. The accuracy, determined by the area under the ROC curve, was greater than 0.97, and assay diagnostic sensitivities and specificities were over 95 and 90%, respectively, for all antigens. Intra (r) and interassay (R) coefficients of variation were under 10 and 20 %, respectively. Selectivity towards target viruses was shown by binding inhibition assays where unbound viruses reduced fluorescence intensities. Diagnostic agreement for samples analysed simultaneously in the monoplex and multiplex assays was almost perfect. In conclusion, a highly sensitive pentaplex assay was validated for the simultaneous identification of antibodies directed against BVDV, BoHV-1, PI3V, BRSV and EBLV in serum. The developed pentaplex assay complies with performance characteristics established by international guidelines for diagnostic tests and may be used as a tool for the implementation of epidemiological surveillance.
