Background: bovine linguatulosis is a zoonotic parasitic disease caused by the pentastomid Linguatula serrata Frölich‚ 1789 (Ichthyostraca: Porocephalida). Nymphal stages of L. serrata have been reported in the heart‚ lungs‚ liver‚ and lymph nodes of bovines (intermediate hosts). Cattle are infected by ingesting the eggs released into the environment by canines (definitive hosts). Objective: to describe a case of linguatulosis in a heifer in the Eastern Plains of Colombia. Anamnesis: a 10-month-old heifer‚ white Brahman breed‚ from San Juan de Arama‚ Meta -Colombia was reported with abdominal dilation and pain. The heifer showed progressive loss of body condition and died. Necropsy findings: poor body condition‚ moderately enlarged mesenteric lymph nodes. Tissue samples of the peritoneum‚ mesenteric lymph nodes‚ and liver were collected‚ fixed in 10 % buffered formalin‚ and sent for histopathological analysis. Histopathology: the morphological diagnosis was a granulomatous peritonitis of parasitic origin. The granulomas showed a central region of caseous necrosis with immature stages of intralesional parasites. There was also severe lymphocytic and histiocytic perivascular infiltrate and foci of fat necrosis. The liver showed moderate centrilobular necrosis and fatty changes and multiple mineralized areas and multifocal granulomatous lymphadenitis with caseous necrosis and severe central mineralization with immature stages of intralesional parasites. The definitive diagnosis was peritonitis and lymphadenitis‚ parasitic. The parasitic forms have a thick cuticle with thin‚ uniform spicules. Parasitology: oval-shaped morphological parasitic structures with spines on the cuticle‚ and acidophilic glands compatible with immature stages of L. serrata were identified. Conclusion: linguatulosis caused by L. serrata is reported for the first time as a cause of mortality in bovine in the Eastern Plains of Colombia. [ABSTRACT FROM AUTHOR]
