Symbiotic Relationships by Jose Teniente
In parallel, studies on mite-bacterial relationships have also increased, but to a lesser extent compared with the insect orders above. Moreover. The relationship between host ecology and feather mite prevalence was analysed in birds. . House Sparrow Passer domesticus and the Starling. Sturnus. To the Editor: There are a wide variety of zoonotic diseases that can be transmitted from birds to humans. Pigeons, chickens, starlings, canaries, and parakeets.
To the morphological description of this new feather mite species we added sequence data on the mitochondrial cytochrome c oxidase subunit I gene fragment COI. The phylogenetic relationships between Trouessartia species are briefly discussed. Feather mite, new species, taxonomy, Trouessartia Introduction The feather mite genus Trouessartia Canestrini, comprises about described species associated predominantly with birds of the order Passeriformes.
A number of undetermined Trouessartia species were reported from the following areas of the world: Muscicapidae and currently includes six valid species distributed in the Indo-Malayan biogeographic region Clements et al.

Feather mites were previously recorded only on two of these species: The main goals of this paper are to realise the description of a new species of Trouessartia and to analyse its relationships within the genus based on molecular data. This is the first species of Trouessartia described from a host of the genus Niltava, although, as mentioned above, two presumably new species of Trouessartia have been reported by Atyeo McClure and Ratanaworabhan from N.
The new species of Trouessartia described herein cannot be referred to any of the seven species groups previously established in the genus SantanaMironov and Kopij, because of having a specific combination of characters.
Materials and methods The material used in the present paper was collected near Shnongrim Meghalaya, India in January The birds were captured using mist nets, identified and visually checked for the presence and collection of mites and released back to the wild. Some specimens preserved in ethanol were used for genetic analysis. Drawings were made using an Olympus CX21 microscope, with a camera lucida drawing device.

The bird specimens were identified according to Rasmussen and Anderton and Grimmett et al. Alternatively, is the author suggesting the use of Permethrin as a toxicant to provide a 'barrier' and further prevent bites?
If it is the latter, than the product should be advocated as a preventative and not a 'treatment'. Either way, the immediate removal of the bird nesting material and the prevention of access to roosting spaces, and then the surface treatment of the immediate and surrounding area with an approved insecticide, should be the main strategy employed to control the mite.
Applying either a toxicant e. Humans should never be treated with insecticides as the contact between the mite and human is purely temporary and incidental, and the infestation is self-limiting once the source of the mites has been found and eliminated.
The listing of the most common bird mites in Australia is not strictly correct.Cardiac Output, Stroke volume, EDV, ESV, Ejection Fraction
The most common is O. To avoid confusion, reference should always be to the species name as different authors quote different common names.

Another species, Dermanyssus gallinae the chicken miteis also relatively similar in appearance and, although most commonly associated with domestic chickens, it can be associated with commensal birds and occasionally attacks humans from this source.
The family name for Ornithonyssus is stated in the article as 'Gamasidae', this is an old name and the current family name is now Macronyssidae.
Larvae however, are rarely collected except from the nesting material and do not feed. The author mentions body lice as a possible differential diagnosis for bites, however body lice are rare in Australian communities other than in homeless, displaced or vagrant persons, and the lice or their eggs usually can be readily found in the clothing of infested individuals.
Other mites, associated with live or stored animal or plant material are more likely to be diagnostic confounders.
However, misidentification of this group is also common, as mite taxonomy is extremely complex. To suggest that they can be 'recognised with the aid of an identification key and a low power microscope' is a gross over-simplification. There are numerous species associated with other vertebrate hosts that have been reported attacking humans, and these are in related mite families and many are morphologically almost identical to Ornithonyssus species; hence specialist entomologists should be used to confirm any putative identification.
