“…Moreover, the presence of eosinophils around the larvae was reduced. This finding contrasts strongly with the high number of eosinophils observed by Nelson and Weintraub (1972) and López et al (2005) at the entry point of the larvae and by Boulard (1975) and Arru et al (1985) in the resting phase of the oesophageal submucosa. Probably this finding is a result of the differences in larvae activity in the skin.…”

“…Histamine can also inhibit neutrophil and eosinophil chemotaxis and the release of lysosomal enzymes from granulocytes (Busse, 1979;Kownatzki et al, 1979). Histopathological descriptions of H. line&urn larvae migrating in naive cattle suggest that inflammatory cells are held at abeyance in naive calves, with a notable absence of neutrophils (Simmons, 1935;Wolfe, 1959;Nelson and Weintraub, 1972). Inflammatory cells are attracted to and surround Hypodenna first-ins&s migrating in resistant animals and the migration track left by migrating larvae or dead larvae in naive animals.…”

Antibodies to Hypoderma lineatum were transferred to calves via colostrum. The antibodies transferred in the colostrum demonstrated specificity to all the H. lineatum first-instar proteins which were resolved by non-denaturing polyacrylamide gel electrophoresis and were capable of mediating a Type I hypersensitivity reaction. The kinetic decline of colostrum-acquired antibodies, the effect upon development of an autologous humoral response to H. lineatum and the host or parasite protective role of these antibodies are discussed.

“…1 4 In contrast to the Hypoderma-H. lineatum larvae requires prior exposure and sen-induced lesion, pentastome-induced lesions tend to be sitization to H. lineatum. 15 All the specimens examined single, more discretely defined, and often caseous and originated from cattle > 1 year old, which had had mineralized. Lesions induced by migration of Ascaris opportunity for prior exposure.…”

“…Survival may range from 0% to 85%, de-tion of the diaphragm, perforation of the thoracic pending on various resistance factors of the host, such esophagus, and extension of cervical inflammatory leas age, previous infestation, and the immunity derived sions into the anterior mediastinum, and to lymphoid therefrom. 7,8,15 Many larvae die within the skin shortly neoplasia. Mediastinal lymphadenitis accompanies a after penetration, especially in previously infected an-variety of inflammatory lesions involving regional imals that elicit a prominent cellular response to pen-structures.…”

Eosinophilic Mediastinitis, Myositis, Pleuritis, and Pneumonia of Cattle Associated with Migration of First-Instar Larvae of Hypoderma Zineatum

Abstract. Migrating first-instar larvae of Hypoderma Zineatum are a frequent cause of focal inflammatory lesions in connective tissues of the mediastinum, parietal and visceral pleura, peritoneum, lungs, diaphragm, and other loci. The lesions are characterized grossly by foci of yellowish or greenish gelatinous edema and microscopically by infiltration of the edematous tissue by a dense array of eosinophils. Lesions were recognized during a period of several weeks in late spring; the timing was attributable to events in the life cycle of the fly. The larvae, which were small (≈ 1 x 4.5 mm), transparent, and unobtrusive, were recovered from lesions in 12 of 20 cattle in which careful parasitologic examination was made.The life history, pathologic effect and myiasis control programs for Hypoderma lineatum and Hypoderma bovis (Diptera: Oestridae) have recently been reviewed 3,4,13 General aspects of the life cycle of H. lineatui are well known. In early spring, adults emerge from pupae that developed from third-instar larvae. These larvae entered the soil during late winter, following emergence from subcutaneous warble cavities. The adult life span is 3-8 days, during which fertilization and egg production occurs. Eggs are deposited on hairs of legs and ventrum of cattle and hatch in a few days, and first-instar larvae penetrate the skin and enter the subcutis within hours. Exact routes of the extensive migration that occurs in the host are not clear, but the esophageal submucosa is generally involved. First-instar larvae remain in the esophageal submucosa for 5-6 months and ultimately reach the subcutis of the back, where they induce a warble cavity, molt twice, and remain for 5-8 weeks. Larvae emerge from the warble, fall to the ground, pupate, and initiate another cycle.Migration is dependent upon elaboration of a collagenase by larvae, and the migratory route is largely or entirely through the collagenous stroma of various organs.19 Although veterinarians are quite familiar with the esophageal and cutaneous lesions of H. lineatum infections, the pathologic changes associated with other segments of their larval migration are less well known. In addition to their usual presence in the esophageal submucosa, first-instar larvae have been observed in various loci, including the subcutis of the limbs and trunk; intermuscular fascia; fascia of epineurium of nerve trunks; peritracheal, periesophageal, and parietal pleural and peritoneal connective tissues; pericardium; visceral peritoneum of spleen, liver, rumen, and intestine; diaphragm; intercostal muscles; and the perirenal connective tissue. 9,19 The histopathology of esophageal lesions induced by first-instar larval migration has been described. 18,19 Lesions in periesophageal, peritracheal, and pleural connective tissues have also been reported. 19Economic loss resulting from Hypoderma lineatum infection includes damage to the hide and carcass ("licked" beef, butcher's jelly), rare anaphylactic reactions, the cost of treatment, treatment accidents (esophagitis an...
