Abstract
Given its importance in veterinary medicine and its impact on human health, bovine tuberculosis demands attention on animal health programs in several countries. New ante- and post-mortem diagnosis protocols are available and facilitate disease detection and control. However, besides the known advantages and disadvantages of each protocol, there is little mention of their costs. This study intends to provide an overview of the economic aspects of diagnostic tests for the control and eradication of bovine tuberculosis.
Highlights
Bovine tuberculosis affects several animal species, and it's considered a zoonosis
In humans tuberculosis caused by M. tuberculosis or by M. bovis are indistinguishable (Allix-Beguec et al, 2010), bovine tuberculosis can produce extrapulmonary symptoms due to oral infection associated with raw dairy products ingestion, a common situation in less developed countries (Katale et al, 2012)
Limitations of the current diagnosis methods contribute to unsuccessful agendas for bovine tuberculosis prevention and control in several places around the world (Waters et al, 2011)
Summary
Bovine tuberculosis affects several animal species, and it's considered a zoonosis. Its causal agent is Mycobacterium bovis, an acid-fast resistant bacillus (Eisenstadt & Hall, 1995; Olea-Popelka et al, 2017). Governmental agencies or research institutes have developed alternative approaches and diagnostic protocols These protocols may include the dosage of interferon-gamma (IFN) (Clegg et al, 2017; Rangen et al, 2009; Wood et al, 1990), ELISA for the detection of anti-M. bovis antibodies (Casal et al, 2017; Marassi et al, 2011; Waters et al, 2006), use of polymerase chain reaction (PCR) technology (Diallo et al, 2016; Wards, 1995; Yahyaoui-Azami et al, 2017; Zumárraga et al, 2012), histopathology (Palmer et al, 2006; Piercy et al, 2007; Silva, 2001) and culturing procedures (Corner et al, 2012; Yates et al, 2017), more often used in a multidisciplinary diagnostic strategy (Marassi et al, 2013). This study presents an extensive literature review on how countries succeed or not in combating bovine tuberculosis, our focus is on the economic aspects
