| Popis: | Aquaculture is a globally relevant sector in terms of production and income. When we think about shrimp farming, Penaeus vannamei, the Pacific white shrimp, has been instrumental in this growth due to its characteristics and advances in production. Despite achievements, it faces significant economic challenges due to the white spot syndrome virus (WSSV), causing considerable losses. This virus has led to significant economic losses, affecting economies such as Ecuador's. The clinical signs of WSSV require rigorous diagnostic procedures, combining histopathological examination and PCR assays. A retrospective study of 900 specimens of Penaeus vannamei in Ecuador highlights the correlation between tissue pathology and mortality rates, enhancing understanding of the direct impact of the disease. Histopathological analysis reveals distinctive intracellular viral inclusions, reflecting disease progression. Although PCR assays provide definitive diagnoses, histopathological evaluation enriches understanding of lesion severity, supporting a comprehensive approach to disease management strategies. |
