“…Similarly, Yacob et al (2004Yacob et al ( , 2006 indicated the existence of an antagonistic interaction between the populations of O. ovis in the nasal cavities and Trichostrongylus colubriformis burdens in the small intestine. This phenomenon was also recently reported in goats (Yacob et al, 2008).…”

“…It seems that O. ovis larvae induce 'at distance' inflammatory reactions in the whole mucosal system. These downregulating effects on nematodes might be eliminated after antiparasitic treatment against O. ovis (Yacob et al, 2002(Yacob et al, , 2004a(Yacob et al, , 2006(Yacob et al, , 2008Terefe et al, 2005).…”

Abstract. Oestrus ovis L. (Diptera: Oestridae) is a cosmopolitan agent of myiasis in sheep and goats. The parasitic phase begins after adult females deposit first-stage larvae (L1) into the nostrils of hosts; these larvae develop into L2 and L3 in the nasal and sinus horn cavities. Sneezing and nasal discharges are the major clinical signs in infected animals. The pathogenesis of O. ovis infection is caused by: (a) the trauma resulting from the mechanical action of spines and hooks during larval movement on mucosal membranes, and, more importantly, (b) an allergenic reaction provoked by molecules excreted/secreted by larvae, of which salivary antigens are those mainly recognized by the host's immune system. The recruitment of immune reactive cells increases gradually from the nasal to sinus cavities in infected hosts. Mast cells, eosinophils, macrophages and lymphocytes are always more numerous in infected than non-infected animals. Humoral (antibody) systemic response of immunoglobulin G (IgG) usually reaches seroconversion 2-4 weeks post-first infection and the highest levels are observed during the development of L2 and L3 larvae. Local antibody responses include specific IgG, which has been found to negatively correlate with larval survival and development. Hypersensitivity reaction, immunomodulation, immunization trials and mixed infections of O. ovis and helminths are discussed.

“…In the present investigation, serum protein and globulin concentrations were declined in February and March while serum albumin was decreased in February only in Rhinoestrusspp infested donkeys. These alterations might be due to blood loss and impaired appetite [25]. In the present investigation, low sodium and high potassium serum levels were observed in Rhinoestrus spp.…”

LITTLE information is available about the homeostasis and alterations appeared against infestation by nasal myiasis caused by Rhinoestrus spp. larvae inEgyptiandonkeys. Therefore, the present work aimed to investigate the hematological and biochemical profiles associated with histopathological features and immunological response developed against Rhinoestrus spp. larvae infestation in donkeys in the winter season. The results revealed that 40 out of 80 examined donkeys were infested bynasal myiasis. IgG values were higher (P< 0.01) in infested donkeys (IND) than non-infested ones all over the winter months while the highest mean larval burden was observed in December (11.6 larvae/animal). Neutrophils% in (IND) increased (P<0.01) during December and February. However, an elevation in lymphocytes% (P<0.05) was observedin (IND) during Decemberand Januarywhile eosinophils% increased (P<0.01) in all winter months. These results paralleled to the nasal fluid cytological profile in which lymphocytes %, neutrophils% and eosinophils% in (IND) increased (P< 0.05) in December, January and February.Glutathione peroxidase, superoxide dismutase and catalase activities in (IND) were declined (P<0.01) in all winter months. Interleukin-2 (IL-2)and tumor necrosis factor-α (TNF-α) elevated (P<0.05) in December and January. The histopathological picture of turbinate bones, olfactory bulb and meninges reflected the blood and nasal fluid cytological picture as there were lymphocytes infiltration, meningitis and satellitosis. The results indicated that Rhinoestrus spp. infestation in donkeys might affect the vital and immunological processes. In addition, Rhinoestrus spp. infestation in donkeys could linked to oxidative stress and shifting the immune response polarization towards Th2 cytokines.
