Onchocercosis is a newly recognized disease in dogs that has been reported with higher frequency in Europe and in the United States. We report a case of a 3-year-old male mongrel stray dog from the Algarve region (South Portugal) who had a retrobulbar granuloma containing a filaroid nematode of the genus Onchocerca. A gravid adult female parasite was embedded in a granulomatous inflammation adj...
Effects of ivermectin and moxidectin were compared on two filarial species: Monanema martini which presents dermal microfilariae and induces Onchocerca-like lesions in its natural murid host Lemniscomys striatus, and Litomosoides sigmodontis (= L. carinii). M. martini microfilariae showed an unusual resistance to ivermectin, in vitro and in vivo; moxidectin was no more efficient. However, the t...
Aspartic proteases are a relatively small group of enzymes which express in various nematodes including Onchocerca volvulus. An estimation of the gene copy number corresponding to the OV7A clone, which contains a cDNA insert encoding approximately two-thirds of the entire coding sequence of aspartic protease of O. volvulus, was made by slot blot analysis in a closely related species O. gibsonig...
OBJECTIVES/HYPOTHESIS To investigate the efficacy of laryngeal reinnervation with ansa cervicalis among unilateral vocal fold paralysis (UVFP) patients with different denervation durations. STUDY DESIGN We retrospectively reviewed 349 consecutive UVFP cases of delayed ansa cervicalis to the recurrent laryngeal nerve (RLN) anastomosis. Potential influencing factors were analyzed in multivariab...
Onchocerca lupi, a zoonotic nematode infecting the eyes of carnivores, has been increasingly reported in dogs from Europe and the USA. In order to improve the current status of knowledge on this neglected filarioid, diagnostic imaging tools (i.e., ultrasound scan, computed tomography and magnetic resonance imaging) are herein used to diagnose canine onchocercosis in two dogs, which scored posit...
Introduction The infrahyoid (strap) muscles act on the thyroid cartilage of the larynx and the hyoid bone to function in speech, swallowing and mastication. The infrahyoid group consists of four paired muscles: sternohyoid, sternothyroid, omohyoid and thyrohyoid. The infrahyoid muscles are hypaxial derivatives, formed by moyblasts of cervical myotomes. The omohyoid consists of superior and infe...
The intensity of natural transmission of Onchocerca ochengi and Onchocerco volvulus by anthropo-boophilic Simulium damnosum s.l. was studied longitudinally in two cattle watering sites of a cattle ranch within a predominantly cattle populated area of the Guinea savanna of Cameroon and related to cattle O. ochengi skin microfilaria abundance. During the 12 months study period, a total of 4696 fl...
