Dermanyssus gallinae (also known as the red mite) is a haematophagous ectoparasite of poultry.It has been implicated as a vector of several major pathogenic diseases. [1] [2] Despite its common names, it has a wide range of hosts including several species of wild birds and mammals, including humans, where the condition it causes is called gamasoidosis.
Ornithonyssus sylviarum (also known as the northern fowl mite) is a haematophagous ectoparasite of poultry. [1] In both size and appearance, it resembles the red mite, Dermanyssus gallinae . [ 2 ] They primarily infect egg laying chickens.
Various chemotherapeutants can be applied for the treatment of infected fish and infected fish farm systems but caution should always be observed during any treatment. Some drugs are toxic to certain fish species and any treatment method must take into account the species of fish (some do not tolerate certain medications).
The individual mites remain external to the epidermis within the follicle, but appear to be within the skin because they are below the general outer surface of the host. The mite Demodex canis is a common cause of demodicosis in dogs. Demodex mites are microscopic, cigar-shaped and have very short legs. These mites seem to feed on epidermal cells.
The microscopic mite Lorryia formosa (). The mites are not a defined taxon, but is used for two distinct groups of arachnids, the Acariformes and the Parasitiformes.The phylogeny of the Acari has been relatively little studied, but molecular information from ribosomal DNA is being extensively used to understand relationships between groups.
Myxobolus cerebralis triactinomyxon Henneguya zschokkei in salmon beard. Diseases can have a variety of causes, including bacterial infections from an external source such as Pseudomonas fluorescens (causing fin rot and fish dropsy), fungal infections (Saprolegnia), mould infections (Oomycete and Saprolegnia), parasitic disorders (Gyrodactylus salaris, Ichthyophthirius multifiliis ...
Infections can be extremely difficult to treat because of the presence of other creatures in the tank, such as corals and other invertebrates, which will not survive standard treatments. Ideally fish with Cryptocaryon are quarantined in a hospital tank, where they can be treated with a copper salt or using hyposalinity, 1.009 specific gravity ...
The treatment of gamasoidosis is further complicated by pesticide resistance among avian mites and their diverse ecological behaviors, which require tailored treatment strategies. [10] Employing a variety of techniques, following a Integrated Pest Management approach, can reduce the likelihood of major re-infestations and limit the development ...
