- ÍtemAborto Bovino: Causas, Diagnostico y Consecuencias.(Universidad Cooperativa de Colombia, Facultad de Ciencias de la Salud, Medicina Veterinaría y Zootecnia, Ibagué, 2019-10-03) Gonzalez Barreto, Angela Tatiana; Mejia Gallego, AndresAbortion is one of the most worrisome problems for farmers, since it manifests sporadically, it occurs as an outbreak of infectious and non-infectious origin, it is difficult for its causative agent to be established. The most relevant agents with predilection to the fetal membrane are: Brucella, Aspergillus sp, Leptospira spp, Infectious Bovine Rhinotracheitis (IBR), Bovine viral diarrhea (vDVB), Neospora caninum, etc., usually cause problems to the embryo depending on virulence and gestation period in which it is found. Abortion is usually noted for its great impact on bovine productions, being one of the most limiting factors for livestock, from which a huge challenge is obtained for veterinary doctors dedicated to livestock production, the following article will contextualize us of the main causes, diagnoses and consequences of bovine abortion.
- ÍtemAborto causado por rinotraqueítis infecciosa bovina (IBR)(Universidad Cooperativa de Colombia, Facultad de Ciencias de la Salud, Medicina Veterinaría y Zootecnia, Ibagué, 2021-06-17) Diaz Peña, Daniel Alejandro; Rojas Varon, Carlos Andres; Bonilla León, LilianInfectious bovine rhinotracheitis (IBR) is a highly contagious disease of cattle. Bovine herpesvirus type 1, of the Herpesviridae family, is a very important pathogen in the development of the disease. There are different strains that can cause different forms of the disease: HBV-1.1 are strains specific to acute respiratory disease, while, HBV-1.2.a and HBV-1.2.b are strains causing respiratory disease and reproductive disease, on the other hand, they are also responsible for infertility, embryonic death and abortions. HBV-1. 3.a and HBV-1.3.b are less common causes of encephalic disease. Primary infection is accompanied by various clinical manifestations, such as infectious bovine rhinotracheitis, abortion, infectious pustular vulvovaginitis and systemic infection in neonates. When animals survive the pathogenicity of the virus, a lifelong latent infection is established in the sensory nerve ganglia, causing any immunological variation to allow reinfection and thus reactivation stimuli can lead to viral re-excretion, responsible for the maintenance of HBV-1 within a herd for extended periods of time. Being a highly contagious virus, the most effective and reliable way to combat the disease in cattle herds is to establish a correct sanitary plan that allows the proper immunization of animals against the virus, thus avoiding the productive, economic and sanitary consequences. The present bibliographic review seeks to compile the most updated and important information on IBR worldwide and nationally, giving it the required importance as a cause of abortions in cattle.
- ÍtemAborto infeccioso en bovinos: causas, diagnóstico y consecuencias.(Universidad Cooperativa de Colombia, Facultad de Ciencias de la Salud, Medicina Veterinaría y Zootecnia, Villavicencio, 2019-07-09) Contreras Quijano, María Angélica; Ismael Monroy, Nestor; Lopera Vasquez, RicaurterThe abortion is one of the most important problems for the breeders, demonstrated of sporadic form, and their infectious and not infectious origin, become difficult that his causal agent establishes. The most relevant agents with predilection to the foetal membrane are: Brucella, Aspergillus sp, Leptospira spp, Infectious Bovine Rhinotracheitis (IBR), viral bovine diarrhea (vDVB) and Neospora caninum, that cause problems to the embryo depending the virulence and the period of gestation in which they are. The abortion are important for his great impact in the bovine productions, being one of the most bounding factors for the breeding, constituting a challenge veterinarians dedicated to cattle production, The following document connect on the principal reasons, diagnoses and consequences of the bovine abortion.
- ÍtemConsideraciones generales & mecanismo de aborto de la neosporosis bovina: revisión de literatura(Universidad Cooperativa de Colombia, Facultad de Ciencias de la Salud, Medicina Veterinaria y Zootecnia; Ibague, 2022-10-25) Garcia Ocampo, Daniel; Morad Quintero, Felipe; Bonilla Leon, LilianBovine Neosporosis is a reproductive pathology generated by N. caninum, which is distributed worldwide. Its parasitic stages are tachyzoite, bradyzoite, and sporozoite. The intermediate host is the dog, which eliminates the pathogen in its feces. The most important sign and sometimes the only one is abortion, which occurs in the middle third of pregnancy, through various mechanisms. Infection can be determined with immunodiagnostic, molecular, histopathological, and isolation tests. At the moment a specific treatment is not known, but preventive measures are known, which is why the prevalence increases.
- ÍtemEnfoque fisiopatológico de la Brucella abortus bovis(Universidad Cooperativa de Colombia, Ibague espinal, Medicina Veterinaria y Zootecnia, 2023-04-25) Eraso Ibarra, Lina Maria; Mora Rocha, Margie Lorena; Lilian Bonilla LeónBrucellosis is a bacterial disease caused by members of the genus Brucella, it is a zoonotic infection that affects different species such as cattle, buffaloes, swine, sheep, goats, horses, and is also a significant cause of reproductive losses, its transmission is by ingestion of infected food products, inhalation of aerosols, direct contact, the latter being the most common. The clinical signs to highlight in bovine females are abortion, placentitis, metritis, stillbirths, placental retention, endometritis and reduced milk production; in males the signs are low fertility, epididymitis, and orchitis mainly. In humans, brucellosis is a debilitating and chronic disease, with clinical signs such as joint pain, excessive sweating, fatigue, muscle pain, presenting more serious signs such as arthritis, inflammation and infection of the testicles, spleen, liver, meningitis and encephalitis. In Colombia, the (ICA) Colombian Agricultural Institute, is the regulatory entity that designs strategies to prevent, control and reduce sanitary, biological and chemical risks, for animal and plant species that may be generating damage at the agricultural level in the nation, where the Brucella bacteria, enters the inspection categories, carrying out vaccination plans, biological management strategies and sanitary measures to prevent distribution through epidemiological surveillance, eliminating sources of infection
- ÍtemLeptospirosis bovina enfocado en el potencial zoonótico, alternativas de control y tratamiento(Universidad Cooperativa de Colombia, Facultad de Ciencias de la Salud, Medicina Veterinaría y Zootecnia, Ibagué, 2022-05) Gutierrez Nieto, Andrea Camila; Masmela Castillo, Raúl Andrés; Bonilla León, LilianLeptospirosis is an important epidemiological disease, whose etiological agent is zoonotic with a negative impact on the animal population and public health.The number of serovars of leptospira is increasing, due to advances in molecular techniques for rapid detection, allowing sources of infection to be detected and control measures to be focused.Studies in Colombia have been sectorized and isolated, which has not allowed a systematic evaluation of the importance and interaction of the different determinants of the pathology.The importance of new treatment alternatives plays a fundamental role in deepening natural alternative medicine. The objective of this review is to collect current information on the pathophysiology and zoonotic potential, as well as some control and treatment alternatives.
- ÍtemLeptospirosis bovina y su impacto en la reproducción(Universidad Cooperativa de Colombia, Facultad de Ciencias de la Salud, Medicina Veterinaría y Zootecnia, Ibagué, 2023-08-30) Quintero Garcia, Tino Herley; Gonzales Navarro, Juan José; Bonilla León , LilianLeptospirosis is a zoonotic disease that is present in tropical, subtropical and temperate zones, and also represents an impact on public health involving humans, domestic and wild animals. It is an infectious disease that produces significant economic losses. In the department of Tolima; cattle are very susceptible to the disease after the rainy season; Farms where the soils have a high capacity to retain water are a great source of infection and where the population at occupational risk involves workers from animal welfare plants, waste collection, sewerage and aqueduct. This disease is caused by a gram-negative bacterium that has a tropism for the uterus, hence its negative impact on reproduction, but it can also affect other organs such as the liver, kidney, among others; It is through the urine that the disease is excreted and spread; This disease occurs interrupting pregnancy and generating an economic impact, due to abortions and weak born pups, it should be noted that it is among reproductive diseases along with campylobacteriosis, trichomoniasis, brucellosis, neosporosis, bovine viral diarrhea (BVD) and Infectious Bovine Rhinotracheitis (IBR) among others, a correct diagnosis must be made since they occur in a similar way with other reproductive diseases. This infection has three acute, sub-acute and chronic phases. Abortions occur when the release of prostaglandin F2 α (PGF2α) is generated and leads to lysis of the corpus luteum (CL) and a decrease in progesterone P4, which generates an unfavorable environment for the embryo that ultimately cannot be recognized by the mother. given by interferon-tau (INT-t), for its diagnosis the main test that exists is MAT microagglutination, later provide antibiotic therapy with aminoglycosides of choice dihydrostreptopenicillin together with vaccination in order to prevent the disease these vaccines must be supplied immediately annually in animals and finally in the department of Tolima it is necessary to generate complete sanitary plans in bovines such as vaccination with different strains and different commercial vaccines each year, quarantine for newly admitted animals, periodic serological tests, hygiene, biosecurity for workers and operators, with this we can guarantee public health and the economy of ranchers in the department of Tolima.
- ÍtemRevisión Bibliográfica de algunas enfermedades de origen infeccioso en bovinos(Universidad Cooperativa de Colombia, Facultad de Ciencias de la Salud, Medicina Veterinaría y Zootecnia, Ibagué, 2017) Rada Briñez, Ivonne Ximena; Trujillo, DunianThe bovine abortion has a strong economic impact and is a limiting factor of the cattle development in all the countries of the world. Abortion is the premature expulsion of the fetus from the mother and usually occurs by the death of the fetus in the womb; This 43 days of gestation and can occur sporadically, endemic or in the form of an outbreak. Although our country suffers losses due to diseases that affect the reproduction of cattle, only 33% of aboriginal causes are known, of which the percentage of abortions with lesions of probable infectious origin is 5%. The objective of the present study was a bibliographical review on the main reproductive diseases of infectious origin, such as IBR ,DVB brucellosis, leptospirosis,neosporosis and trichomoniasis that cause abortion in cattle.
