Item Coxielose em ruminantes e a febre Q na saúde pública no Brasil(2021-09-17) Zache, Eduardo; Torres, Alexandre Augusto Arenales; http://lattes.cnpq.br/5145322907663650; http://lattes.cnpq.br/9715170506304327Q fever is a zoonosis of worldwide distribution caused by Coxiella burnetii, a gram-negative obligate intracellular bacterium of the order Legionellales, which has been classified as a potential bioterrorism agent. Thus, the present study aims to perform a literature review on Q fever and coxiellosis, with emphasis on its close relationship to public health, due to its zoonotic nature, in addition to its economic importance for national livestock. Cattle and small ruminants represent the most frequent sources of infection in humans, with inhalation of contaminated aerosols from infected animal products being the main form of transmission. The high occupational risk is related mainly to cattle and small ruminant breeders and veterinarians, even people with sporadic contact with animals, such as employees in veterinary clinics. Infections in humans are usually asymptomatic, but can evolve into serious complications such as endocarditis, which can be fatal if not treated appropriately. In ruminants the most important clinical manifestations are reproductive disorders such as abortion, stillbirth fetus, endometritis, infertility and mastitis, but the agent has also been identified in cattle with endocarditis. The clinical diagnosis is difficult, due to the nonspecificity of the clinical signs. Specific indirect diagnostic tools such as the indirect microimmunofluorescence test is considered a reference technique for humans, however for ruminants the molecular method of polymerase chain reaction (PCR) is a reliable method to detect the elimination of the agent in body fluids (feces, milk and vaginal mucus) that may be intermittent. The prophylactic combination of doxycycline and hydroxychloroquine has been shown to be effective in preventing endocarditis and is indicated in the presence of risk factors in humans. In animals, the use of antimicrobials has not been effective. In recent years, several cases of C. burnetii infection in humans and animals have been reported in Brazil, with evidence of Q fever circulating in humans in the southeast and northeast regions, and in animals in the southeast, central-west and northeast regions. The Ministry of Agriculture, Livestock and Supply classifies the disease in category 3 (three) of the list of diseases of mandatory notification to the Veterinary Service, however, it is not recognized by the Brazilian Ministry of Health as of mandatory notification in humans. With all zoonotic diseases, the control of the disease in animals and the interdisciplinary following the principles of One Health, will directly influence the results observed in humans.Item Coronavírus bovino: sua relevância na saúde animal e pública global(2021-10-27) Beserra, Lucas Alencar Fernandes; Silva, José Augusto Bastos Afonso da; http://lattes.cnpq.br/9754109726295756; http://lattes.cnpq.br/6178148321524675Bovine coronavirus (BCoV) is a member of the coronaviridae family. It is an important pathogen with high prevalence worldwide. This virus, a pneumoenteric agent, is responsible for the occurrence of three distinct clinical syndromes, described respectively as diarrhea in calves, dysentery in adult animals and respiratory tract affection in cattle of all ages. The presence of this virus in the herd causes substantial economic losses, also, in animal welfare and in the health of the herd. Thus, the objective of this work is to demonstrate the main characteristics of BCoV, as well as describe the occurrence of this agent in other species of domestic and wild ruminant animals. In addition, highlight the coronavirus as a zoonotic pathogen in the context of public health. Coronary virus in cattle is characterized by its enteropathogenic and respiratory forms, symbolized respectively by mucohemorrhagic enterocolitis in calves (EBCoV-CD), dysentery in adult animals (EBCoV-WD) and interstitial pneumonia (RBoV) mainly in calves. Although this agent is considered a specific pathogen of domestic cattle, its occurrence is also described in other species of domestic and wild ruminants, as well as in humans. At the interface between animals and humans, coronavirus is described as an infectious, zoonotic and emergent disease, this agent being described as the only member of the order Nidovirales to cause disease in humans. In this context, several species are incriminated as intermediate hosts in the transmission mechanism to humans, for example, dromedary camels in the transmission of MERS-COV. The role of cattle in the context of intermediate host or reservoir of this virus for humans is still poorly understood, such as the susceptibility and transmission of SARS-CoV-2. However, one of the enteric coronavirus strains in humans (HCoV-OC43) would have evolved from ancestral strains of the bovine coronavirus, which crossed the interspecies barrier and, consequently, established the infection in humans. Thus, we can consider the diseases caused by BCoV as important from an economic point of view, sanitary in the welfare of the herd, in addition to the importance of this agent in the zoonotic context, thus enabling risks to animal and human health.
