Resumen
El linfoma asociado al virus de la leucemia bovina (BLV-AL) es una enfermedad del ganado muy extendida. El linfoma afecta con mayor frecuencia a los ganglios linfáticos, el corazón y el abomasum en el ganado adulto.
Área de la Ciencia:
- Patología veterinaria
- En el campo de la oncología
- Epidemiología
Sus antecedentes:
- El linfoma asociado al virus de la leucemia bovina (BLV-AL) es una enfermedad neoplásica significativa en el ganado bovino en todo el mundo.
- BLV-AL causa pérdidas económicas sustanciales en la industria mundial del ganado bovino.
- Comprender la distribución anatómica del linfoma es crucial para el diagnóstico y el tratamiento.
Objetivo del estudio:
- Para describir la distribución anatómica del linfoma en el ganado adulto.
- Analizar los casos de linfoma diagnosticados en los laboratorios de diagnóstico veterinario (VDL) y por los veterinarios de campo.
- Identificar los órganos más afectados en el linfoma bovino.
Principales métodos:
- Análisis retrospectivo de 5 290 informes de autopsias de bovinos entre 2001 y 2024 de 3 LDV.
- Se incluyen 2.200 autopsias presentadas por veterinarios de campo.
- Selección y análisis de 165 casos de linfoma bovino basados en informes de diagnóstico.
Principales resultados:
- Se diagnosticó linfoma en 165 casos de ganado adulto.
- Los órganos afectados con mayor frecuencia fueron los ganglios linfáticos (70,3%), el corazón (62,4%) y el abomasum (51,5%).
- Otros órganos afectados incluyen el riñón (32,7%), la pared intestinal (26,1%) y la pared del estómago (19,4%).
Conclusiones:
- El linfoma en el ganado adulto tiene un patrón de distribución anatómica distinto.
- Los ganglios linfáticos, el corazón y el abomasum son los sitios primarios para el linfoma bovino.
- La afectación del riñón y la pared intestinal es más común que el útero o el espacio epidural de la médula espinal en el linfoma bovino adulto.

01:15Secondary Lymphoid Organs
3.2K
Secondary organs, including lymph nodes, the spleen, and mucosa-associated lymphoid tissue (MALT), work harmoniously to protect us from disease and infection.
The spleen is a vital organ in the lymphatic system, nestled in the upper left side of the abdomen. It is composed of two primary regions: the red pulp and the white pulp, each having distinct functions. The red pulp performs a significant role in blood filtration. It efficiently purges the blood of old or damaged red blood cells and...

01:16Primary Lymphoid Organs

Primary lymphoid organs are pivotal in the formation, development, and maturation of lymphocytes, the white blood cells that serve as the backbone of our immune system. This crucial function underscores their fundamental role in maintaining our overall health and immunity. The two primary lymphoid organs of prime importance are the red bone marrow and the thymus.
The red bone marrow is a soft, spongy tissue nestled in the interior of long bones such as the humerus and femur. It is the site...

Lymphoid cells and tissues are integral to the immune system, which is crucial in maintaining our body's defense against harmful pathogens. They form the building blocks of lymphoid organs, which include the spleen, thymus, and lymph nodes.
Lymphoid cells consist of various types of immune system cells. These include B and T lymphocytes, which are responsible for producing antibodies and killing infected cells, respectively. Dendritic cells act as messengers between the innate and adaptive...

01:23Detailed Structure and Function of Lymph Nodes
2.4K
Lymph nodes are bean-shaped structures that cluster along the lymphatic vessels in the inguinal, axillary, and cervical regions. Each node is divided into compartments by a capsule that extends trabeculae inward.
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...

01:15Development of the Lymphatic System
1.1K
The development of lymphatic tissues and vessels in embryonic life begins around the fifth week. These structures originate from the mesoderm layer, with lymph sacs emerging from developing veins.
The first lymph sacs to form are the paired jugular lymph sacs located at the junction of the internal jugular and subclavian veins. From these sacs, lymphatic capillary plexuses extend to the thorax, upper limbs, neck, and head, eventually forming lymphatic vessels. Each jugular lymph sac maintains a...
