Abstract

The cheyletid mites that parasitize mammals have been neglected for a long time in Brazil, although they can be common on pets and cause injury to their hosts. Recently, Cheyletiella parasitivorax was found parasitizing a rabbit in Brazil which represents a new host and distribution record for the mite species. An illustrated dichotomous key for the identification of the species in this genus and data from the literature are provided.

Resumo

Os ácaros da família Cheyletidae que parasitam mamíferos são negligenciados há muito tempo no Brasil, embora eles sejam comuns em animais domésticos. Considerando as dificuldades morfológicas para diagnosticar as espécies dessa família que infestam mamíferos, este estudo refere-se a uma nova ocorrência de Cheyletiella parasitivorax incluindo os poucos registros de literatura. Além disso, também está sendo apresentada uma chave dicotômica ilustrada para identificação de espécies desse gênero.

Introduction

The superfamily Cheyletoidea consists of the following five families of mites: Cheyletidae Leach 1815; Demodicidae Nicolet 1855; Harpirhynchidae Dubinin 1957 (including Ophioptinae); Psorergatidae Dubinin 1957 and Syringophilidae Lavoipierre 1953. Except for Harpirhynchidae and Syringophilidae, which are mainly associated to reptiles and birds, the other families usually parasitize mammals, and some are also associated with arthropods.

Cheyletidae is represented by approximately 400 species worldwide, distributed in 74 genera. The genera are divided into two groups; one of them consists of free-living mites and predators of arthropods, including other mites, and comprises more than half of the described species; the second group consists of species associated with different classes of vertebrates, including humans (Gerson et al., 1999Gerson U, Fain A, Smiley RL. Further observations on the Cheyletidae (Acari), with a key to the genera of the Cheyletinae and a list of all known species in the family. Bull Inst R Sci Nat Belg 1999; 69: 35-86.; Walter et al., 2009Walter DE, Lindquist EE, Smith IM, Cook DR, Krantz GW. Order Trombidiformes. In: Krantz GW, Walter DE. A manual of Acarology. Lubbock: Texas Tech University Press; 2009. p. 233-420.).

In a phylogenetic reconstruction of the Cheyletidae published by Bochkov & Fain (2001)Bochkov AV, Fain A. Phylogeny and system of the Cheyletidae (Acari: Prostigmata) with special reference to their host-parasite associations. Bull Inst R Sci Nat Belg 2001; 71: 5-36., the authors proposed 15 tribes in the family, which were maintained by Bochkov (2009)Bochkov AV. A review of mites of the parvorder Eleutherengona (Acariformes: Prostigmata) - permanent parasites of mammals. Acarina: KMK Scientific Press; 2009.. Bochkov & Fain (2001)Bochkov AV, Fain A. Phylogeny and system of the Cheyletidae (Acari: Prostigmata) with special reference to their host-parasite associations. Bull Inst R Sci Nat Belg 2001; 71: 5-36. included four genera in the Cheyletiellini tribe: Cheyletiella Canestrini 1886, Eucheyletiella Volgin 1969, Nihelia Domrow & Baker 1960 and Criokeron Volgin 1966, which are associated with mammals; and three genera in the Ornithocheyletiini tribe: Bakericheyla Volgin 1966; Neocheyletiella Baker 1949 and Ornithocheyletia Volgin 1964, which are associated with birds.

Fain & Bochkov (2001)Fain A, Bochkov AV. A review of some genera of cheyletid mites (Acari: Prostigmata) with descriptions of new species. Acarina (Mosc) 2001; 9(1): 47-95. synonymized the genus Bicheyletiella Fain 1972 with Cheyletiella, transferring Bicheyletiella romerolagi Fain 1972 to Cheyletiella. In addition, they synonymized two other species of Cheyletiella; as a result, there are currently five valid species: Cheyletiella blakei Smiley 1970; Cheyletiella parasitivorax (Mégnin 1878); Cheyletiella romerolagi (Fain 1972Fain A. Notes sur les acariens des famill1es Cheyletidae et Harpyrhynchidae producteurs de gale chez les oiseaux ou les mammiferes. Acta Zool Pathol Antverp 1972; 56: 37-60. PMid:4668512.); Cheyletiella strandtmanni Smiley 1970; and Cheyletiella yasguri Smiley 1965. Usually, C. yasguri is associated with dogs (Fain et al., 1982Fain A, Scheepers L, De Groot W. Long-lasting pruriginous dermatitis in a woman caused by an acarian dog parasite Cheyletiella yasguri Smiley. Rev Med Liege 1982; 37(18): 623-625. PMid:6183724.), C. blakei with cats (Pfeiffer, 1979Pfeiffer H. Cheyletiella-befall der Hauskatze. Z Parasitenkd 1979; 59(1): 95-106. http://dx.doi.org/10.1007/BF00927850.
http://dx.doi.org/10.1007/BF00927850...
) and C. parasitivorax with rabbits (Bronswijk & Kreek, 1976Bronswijk JEMH, Kreek EJ. Cheyletiella (Acari: Cheyletiellidae) of dog, cat and domesticated rabbit, a review. J Med Entomol 1976; 13(3): 315-327. http://dx.doi.org/10.1093/jmedent/13.3.315. PMid:1011235.
http://dx.doi.org/10.1093/jmedent/13.3.3...
). These nonburrowing mites can cause severe dermatitis on their hosts including people who are in contact with infected pets (Keh et al., 1987Keh B, Lane RS, Shachter SP. Cheyletiella blakei, an ectoparasite of cats, as cause of cryptic arthropod infestations affecting humans. West J Med 1987; 146(2): 192-194. PMid:3825118.; Fain & Bochkov, 2001Fain A, Bochkov AV. A review of some genera of cheyletid mites (Acari: Prostigmata) with descriptions of new species. Acarina (Mosc) 2001; 9(1): 47-95.).

The study of the cheyletid mites parasitic on vertebrates has been neglected in Brazil and other countries in South America, although they can cause injury to humans and other hosts. Since there is still little information about this family in Brazil, we are providing a new locality record of C. parasitivorax and including information on the genus gathered from the literature. In addition, an illustrated dichotomous key to separate the species of this genus is provided, based on the key published by Fain & Bochkov (2001)Fain A, Bochkov AV. A review of some genera of cheyletid mites (Acari: Prostigmata) with descriptions of new species. Acarina (Mosc) 2001; 9(1): 47-95..

Materials and Methods

Specimens of C. parasitivorax were collected on an infested rabbit, Oryctolagus cuniculusL. in the Jundiai municipality (23° 11′ 11″ S 46° 53′ 4″ W), São Paulo state, Brazil. The collected material was preserved and stored in 100% alcohol. Later, part of the material was slide-mounted in Hoyer’s medium for identification. The slide preparations were in accordance with Walter & Krantz (2009)Walter DE, Krantz GW. Collecting, rearing, and preparing specimens. In: Krantz GW, Walter DE. A manual of Acarology. Lubbock: Texas Tech University Press; 2009. p. 83-96., and a part of them was deposited in the collection of the Pathology Department of UNESP, Jaboticabal, named as “Museu Didático de Parasitologia do Departamento de Patologia Veterinária da UNESP de Jaboticabal”. The specimens were identified to genus according to Gerson et al. (1999)Gerson U, Fain A, Smiley RL. Further observations on the Cheyletidae (Acari), with a key to the genera of the Cheyletinae and a list of all known species in the family. Bull Inst R Sci Nat Belg 1999; 69: 35-86. and to species using the key published by Fain & Bochkov (2001)Fain A, Bochkov AV. A review of some genera of cheyletid mites (Acari: Prostigmata) with descriptions of new species. Acarina (Mosc) 2001; 9(1): 47-95. along with the examination of type material and their original descriptions (Smiley, 1965Smiley RL. Two new species of the genus Cheyletiella. Proc Entomol Soc Wash 1965; 67(2): 75-79., 1970Smiley RL. A review of the family Cheyletiellidae (Acarina). Ann Entomol Soc Am 1970; 63(4): 1056-1078. http://dx.doi.org/10.1093/aesa/63.4.1056.

Besides the specimens of C. parasitivorax collected in the present study, we examined material of this species deposited at Acari Collection of the Instituto Butantan, São Paulo (IBSP), and from the collection of the National Museum of Natural History, [formerly United States National Museum -USNM], which is housed at the Systematic Entomology Laboratory (BARC-USDA-ARS) in Beltsville, Maryland. Types and material of other species of Cheyletiella deposited at the collection of the USNM were also examined by one of us (RB-S) in order to prepare the illustrations. The material of C. parasitivorax from Jundiaí was photographed using an Olympus microscope, DP 73, and CellSens Imaging software (Olympus), in the Immunoparasitology Laboratory, Department of Veterinary Pathology, Universidade Estadual Paulista (UNESP Jaboticabal). Type species and material were also photographed using a Zeiss Axioplan 2 imaging with DIC and Phase Contrast microscope in the USNM. Images were prepared with Adobe Photoshop v. 13.0 and Inkscape V.2. The distribution map was prepared using DIVA-GIS.

Results and Discussion

Cheyletiellinae is characterized by the presence of a feather-like empodia on tarsi of the legs I-IV, tarsi without claws and solenidia absent on tibia of the leg I. Cheyletiella has sickle-like setae and lacks comb-like setae on the palptarsus; has an edentate palpal claw; peritremes with more than three broad links; idiosoma oval; legs II and III separated; a single wide propodosomal shield present bearing 4-5 pairs of setae; dorsal setae slender, nude or barbed; humerals similar to the other dorsal setae (l1); solenidion (φ) present on genu of the leg I and absent on tibia of the leg I; all tarsi without claws and with feather-like empodia (Gerson et al., 1999Gerson U, Fain A, Smiley RL. Further observations on the Cheyletidae (Acari), with a key to the genera of the Cheyletinae and a list of all known species in the family. Bull Inst R Sci Nat Belg 1999; 69: 35-86.).

Listed below are the types and material examined of Cheyletiella species, used to prepare the identification key modified from that of Fain & Bochkov (2001)Fain A, Bochkov AV.

Cheyletiella romerolagi (Fain, 1972Fain A. Notes sur les acariens des famill1es Cheyletidae et Harpyrhynchidae producteurs de gale chez les oiseaux ou les mammiferes. Acta Zool Pathol Antverp 1972; 56: 37-60. PMid:4668512.) was not examined, due the fact there are no types or material deposited at the USNM collection. The species was described from specimens found on a volcano rabbit, Romerolagus diazi (Ferrari-Pére), in New York, USA and also has been recorded in Mexico on the same host (Gerson et al., 1999Gerson U, Fain A, Smiley RL. Further observations on the Cheyletidae (Acari), with a key to the genera of the Cheyletinae and a list of all known species in the family. Bull Inst R Sci Nat Belg 1999; 69: 35-86.). According to Fain (1972)Fain A. Notes sur les acariens des famill1es Cheyletidae et Harpyrhynchidae producteurs de gale chez les oiseaux ou les mammiferes. Acta Zool Pathol Antverp 1972; 56: 37-60. PMid:4668512., the chaetotaxy of C. romerolagi is similar to that of other species of Cheyletiella. Fain & Bochkov (2001)Fain A, Bochkov AV.

Clinical case

A four-year-old male rabbit was observed with dandruff on its back and itching due to the parasitism of C. parasitivorax. The clinical signs started twenty days before the patient was taken to the clinic (Figure 6). The rabbit had no contact with other animals according to its owners. Skin scraping and acetate tape impression test were made. The owners had moved to another place about two months before and probably the adaptation stress caused the loss of balance between the parasite and its host. The animal was treated with a single administration of selamectin pour-on (Zoetis Revolution® 6%) and daily brushings of the fur. No dandruff and itching were observed after three weeks of the treatment.
