Summary For the first time this century, we report tract migration dermatitis provoked by Gasterophilus sp. larvae in horses at a farm Spain where selective parasite control programme has been employed for more than decade. At equine farm, two over 25 years old presented alopecic lesions form of streaks masseteric and maxillary region face. The clinical histological features these animals are d...

Hookworm-related cutaneous larva migrans is caused by the intradermal migration of soil-dwelling filariform larvae dog and cat hookworms, most commonly Ancylostoma, usually develop itchy skin lesions, consisting migrating superficial serpiginous traces, or sometimes stationary follicular eruptions. The plantar topography on regions body in contact with sand beaches Antilles, West Africa East As...

Gnathostomiasis is common in Southeast Asian countries and can be found sporadically in other parts of the world mainly due to human migration. The definitive diagnosis can be given either by identification of the parasite isolated from the patient or through histologic section of the lesion. It is therefore important for pathologists to be familiar with the morphology of parasitic larvae which...

HE detection of bands of enzyme activity showing different rates of migration Tduring starch gel electrophoresis has been reported repeatedly in recent years. This technique has been particularly useful in genetic studies, and many cases are now known of a band or bands, termed isozymes, which are under genetic control. Such control has been demonstrated for alkaline phosphatase in bacteria ( S...

Experimental evidence is presented which confirms the reports by Shope (1, 2) that swine lungworms can serve as an intermediate host in transmitting swine influenza virus to pigs. The virus is present in a masked non-infective form as he showed and a provocative stimulus is necessary to initiate infection. Multiple injections of Ascaris extract or the migration of Ascaris larvae furnished the n...

Cutaneous larva migrans is skin eruption caused by infestation and migration of animal hookworm larvae in the human skin. It is common in tropics and sub‒tropics.1‒3 CLM has become common among travellers. The disease mainly occurs in resource‒poor communities.1 CLM presents as typical erythematous, serpiginous, pruritic, migratory skin eruptions. Lesions usually depends on area in contact with...

In order to research the influences of the somites or their derivatives on the migration and differentiation of neural crest cells, unilateral extirpation of somites was performed in the larvae of the salamander (Hynobius lichenatus Boulenger). Two types of neural crest cells appeared in the somite-free environment. They could already be distinguished from each other shortly after beginning of ...

american foulbrood (afb) is the most serious brood disease of the honey bee. traditional methods are reliable but rather slow simply because they are based on biochemical, morphological and physiological identification of cultivated isolates. the aim of this study is the detection of paenibacillus larvae larvae spores in honey and diseased larvae samples by culture and pcr. therefore 54 samp...

Each year the Mythimna separate (Walker), undertakes a seasonal, long-distance, multigeneration roundtrip migration between southern and northern China. Despite its regularity, the decision to migrate is facultative, and is controlled by environmental, physiological, hormonal, genetic, and molecular factors. Migrants take off on days 1 or 2 after eclosion, although the preoviposition period las...

a series of two experiments was conducted to study the optimum dietary protein level and protein to energy ratio of lemon fin barb hybrid larvae. in experiment 1, five isocaloric diets (4700 kcal per kg) ranging from 40 to 60% protein in 5% increments were fed to triplicate groups of lemon fin barb hybrid larvae (initial weight: 0.10 ± 0.01 mg per fish) for 21 days. weight gain of fish was prop...
