The purpose of our research was to test the therapeutic efficacy of the acaricide «Simparica®» in combination with the biostimulator «Catosal» and the hepatoprotector «Tioprotectin» for demodicosis in dogs in the conditions of veterinary clinics in the Kamianets-Podilskyi, Ukraine. The study has been performed on dogs of different genders, ages and breeds that had a generalized form of demodicosis (affected at least 6 areas on the body of animals), to test the effectiveness of this drug in different treatment schemes. Acarological studies of scrapings from the skin of experimental animals for the presence of live or dead mites Demodex canis or their eggs have been carried out by the vital method according to D.O. Pryselkova. As a result of the conducted researches the choice of acaricidal drugs and development of complex therapeutic measures for demodicosis of dogs has been experimentally substantiated. The drug «Simparica®» has proved to be quite effective against demodicosis of dogs, even with a single use. The dependence of the effectiveness of the use of prolonged acaricide «Simparica®» on clinical forms of demodicosis has been shown. The absolute therapeutic effect of acaricide is obtained in the scaly form of demodicosis. However, in pustular and mixed clinical forms of demodicosis, its effectiveness decreased to 71.4 and 57.1%, respectively. In combination with the drug of pathogenetic therapy «Catosal» for pustular and mixed forms of demodicosis, the therapeutic efficacy of the drug «Simparica®» increases to 85.7%. When added to the scheme of hepatoprotector “Thioprotectin”, it is possible to achieve 100% therapeutic effect in pustular forms of demodicosis. However, in severe mixed form of demodicosis, the effectiveness was not absolute and was only 85.7%. In case of generalized demodicosis of dogs, regardless of clinical forms, it is recommended to use the acaricide «Simparica®» in combination with the drug «Catosal» and in the combination of «Catosal» and «Thioprotectin».

Abstract Background: Orally administered fluralaner (13.64% w/w) is effective for treating canine generalized demodicosis. A study was initiated to assess the efficacy of a novel 5.46% w/w fluralaner chewable tablet formulation for monthly administration in the treatment of this disease.Methods: Client-owned dogs diagnosed with generalized demodicosis were acclimatized to laboratory conditions and randomized to receive either orally administered fluralaner (Bravecto® 1-Month) (10.0 to 14.4 mg/kg body weight) (n = 8) or topical imidacloprid-moxidectin (Advocate® for dogs, Elanco) applied per label on Days 0, 28 and 56 (n = 8), or more frequently for ongoing severe demodicosis. On Days -2, 28, 56 and 84, deep skin scrapings were taken from 5 sites on each dog for mite identification and counting, and semi-quantitative clinical assessments of generalized demodicosis were recorded. Primary efficacy was based upon arithmetic mean mite count reductions relative to pre-treatment.Results: By Day 28, mean pre-treatment mite counts, >600 in both groups, were significantly reduced by 99.7% and 89.5% (both P < 0.001) in the fluralaner and imidacloprid-moxidectin groups, respectively. Parasitological cure (100% reduction in mite counts on Days 56 and 84) was achieved in all fluralaner-treated dogs (100%) and in 2 imidacloprid-moxidectin treated dogs (25%). In the imidacloprid-moxidectin group, the reduction in mean mite counts was 89.5% (Day 28), 94.4% (Day 56) and 97.5% (Day 84). All study dogs were free of crusts on Days 56 and 84. Scales resolved by Day 84 in all fluralaner-treated dogs and in 3 imidacloprid-moxidectin treated dogs. All fluralaner-treated dogs and 5 imidacloprid-moxidectin treated dogs had > 90% hair re-growth on Day 84.Conclusion Three consecutive monthly oral administrations of fluralaner (5.46% w/w) flavored chewable tablets (minimum dose rate 10 mg/kg body weight) eliminated Demodex canis mites from dogs diagnosed with generalized demodicosis.

Scabies mites, in particular Sarcoptes scabei and Demodex canis, remain undesirable but permanent members of zoocenoses in metropolis around the world. This is due to the contacts of domestic animals with wild relatives (foxes, raccoon dogs, coyotes), which are massively infected with various types of ticks. The purpose of our research was to find out the epizootic situation with demodicosis and sarcoptic mange of domestic dogs in Kyiv, as well as to establish the sources of their infection. The actual results were obtained on the basis of the "Veterinary Clinic of Doctor Medvedev" (Kyiv) according to the data of routine work with patients for 2009-2020. Diagnostic procedures consisted of clinical and dermatological examination of dogs, examination of skin scrapings, trichoscopy, "Scotch tape" test, a Wood's lamp examination and others. Over 11 years, 1473 dermatological examinations of domestic dogs were carried out. Of these, 230 dogs (15.6%) suffered from demodicosis at the age of 5 months to 7 years. Sarcoptic mange was much less common: a total of 59 sick dogs (4.0%) were identified. Both of acaroses were seasonal, with an increase in the incidence in fall and winter. Regarding the breed factor: Pugs (10.43%), Staffordshire Terriers (10.0%) and French Bulldogs (9.56%) were more prone to demodicosis; to sarcoptic mange – German wirehaired pointer (13.6%), German hunt terrier (11.9%) and Shorthaired pointer (10.2%). The stray dogs and cats were source most often of infection of domestic decorative dogs with mites Sarcoptes scabei var canis. Hunting dogs mainly became infected during the hunting season during contact with animals of the wild fauna, most often – foxes. Clinical manifestations of acaroses occurred mainly in young animals not older than 3 years (70.5 and 76.7% for demodicosis and sarcoptic mange, respectively). In addition, in male dogs sarcoptic mange is more often recorded (59.3%), in female dogs – demodicosis (53.9%). Key words: scabies, mites, Sarcoptes scabiei, Demodex canis, prevalence, dogs, foxes.

Background: Demodicosis, also named as demodectic mange, red mange or follicular mange (Shrestha et al., 2015). In dogs, Demodex canis is acquired from the dam during the first few hours of life, probably during suckling (Greve and Gaafar, 1966). Demodicosis can be defined on the basis of two forms localized and generalized (Shipstone, 2000) with juvenile or adult onset. The ideal confirmation of diagnosis of demodicosis were established by the laboratory analysis of the cutaneous skin scrapings. Various drugs have been used for treating canine demodicosis. Till date no research work has been done on herbal nano medicine against demodicosis in dogs especially in Mizoram. Keeping these points in view the present study was made to formulate the herbal nanomedicine against demodicosis in dogs.Methods: Present investigation was conducted for curing canine demodicosis with the help of herbal essential oils along with its ameloriation with silver Nanoparticles. A total of 1200 dogs were screened for canine demodicosis and 35 cases were confirmed for canine demodicosis by skin scraping and amp; PCR examination.Result: The typical characteristics of Demodex spp. were confirmed in (20/35) 57.14% cases by skin scraping examination while PCR examination demonstrated (35/35) 100% by the amplification of an approximately 483 bp. Sequencing of PCR products were analyzed by BLAST and amp; the results indicated 99.7% identical to available sequences of D. canis MG372354 (1:99.7) and 98.8 identical with D. canis KU253790 (33:98.8) and amp; MG372359 (1:96.8). The sequence of the PCR product of positive samples was submitted to NCBI GenBank for accession number and MK177513 accession number was obtained for GenBank. From the present study it seems that Herbo-Nano medicine can be an effective alternative of Amitraz in case of demodicosis.

La sarna demodécica es el segundo tipo de sarna más común en perros. Por lo tanto, se planteó determinar la prevalencia de sarna demodécica en perros (Canis Lupus Familiaris) domésticos en los sectores de Eloy Alfaro, Ignacio Flores, Juan Montalvo y La Matriz, del cantón Latacunga. La metodología de la investigación incluyó el muestreo de 72 perros con problemas dermatológicos, de diferente sexo, edad, con o sin propietario, el método realizado fue mediante raspado cutáneos, los cuales se realizaron con hoja de bisturí hasta producir un leve sangrado capilar, estas muestras eran transportadas al laboratorio en refrigeración, para su observación se agregó aceite mineral y fueron observados al microscopio óptico a 10X. La prevalencia de Demodex canis fue de 16,67%. De esta manera se demuestra la existencia de este ácaro en el cantón de Latacunga, por lo cual los dueños deben llevar a sus mascotas a un médico veterinario para implementar un programa de control y prevención de la enfermedad. Una de las limitaciones que se presentaron durante la ejecución del presente estudio, radica en el hecho que la población del cantón de Latacunga no tiene conocimiento sobre los cuidados de sus mascotas y sobre la responsabilidad que adquieren al hacerse cargo de un animal. Por otra parte, los animales no contaban con un carnet de vacunas y los mismos dueños automedican a sus animales o son llevados para su medicación a centros no autorizados.

Демодекозна інвазія є однією з найпоширеніших акарозних хвороб серед собак незалежно від віку, статі та породи тварин. Відомо, що захворювання можуть викликати декілька видів кліщів, а саме Demodex canis (Leydig, 1859), Demodex injai (Desch & Hillier, 2003) та Demodex sp. cornei. Ці кліщі певною мірою відмінні між собою за морфологічною будовою, місцем локалізації, проте їх об’єднує виразний патогенний вплив, який вони чинять на організм собак. Переважно хвороба має хронічний перебіг і важко піддається лікуванню, тому завдає значних економічних затрат. Незважаючи на широке поширення демодекозу, багато питань епізоотології залишаються недостатньо вивченими, що ускладнює розробку заходів боротьби і профілактики цього захворювання в окремих регіонах. То-му мету цього дослідження – це необхідність з’ясувати розповсюдження демодекозу собак в умовах м. Полтави, закономірності вікової динаміки, а також порідної сприйнятливості. Роботу виконува-ли на базі лабораторії паразитології кафедри паразитології та ветеринарно-санітарної експертизи та клініки ветеринарної медицини «ФОП Локес-Крупка Т. П.» при кафедрі терапії імені професора П. І. Локеса Полтавської державної аграрної академії. Діагноз на демодекоз встановлювали, засто-совуючи удосконалену методику В. О. Євстаф’євої та ін., з використанням суміші «Бішофіту» та гліцерину у співвідношенні 1 : 1. Акарологічне дослідження за дослідний період зробили 562 собакам дванадцяти порід (службові, мисливські, декоративні) та безпорідні, яких було розділено на п’ять вікових груп (собаки до одного року, від одного до трьох років, від трьох до шести років, від шести до дев’яти та собаки віком понад дев’ять років). Під час проведених досліджень встановлено, що собаки на території м. Полтави уражені збудником демодекозу Demodex canis, Leydig, 1859. Інвазо-ваність собак в середньому становила 7,29 %. Доведено, що вік тварин істотно впливає на показник інвазованості. Максимальну екстенсивність інвазії зареєстровано в собак двох вікових груп – тварин віком 1–3 роки та старше 9 років (ЕІ=33,49 та 29,14 % відповідно). Найменш ураженими були соба-ки до 12-ти місячного віку (ЕІ=18,45 %). За результатами досліджень встановлено, що показники екстенсивності демодекозної інвазії залежали від породних особливостей собак. Найбільш ураже-ними збудником демодекозу виявилися собаки мисливських порід та безпорідні тварини. У собак мис-ливських порід показник інвазованості сягав 41,46 %, натомість у безпорідних цей показник стано-вив 26,83 %. Тварини декоративних порід виявилися найменш сприйнятливими до захворювання, се-редня інвазованість у цій групі собак склала 12,21 %.

O crescente número de animais de companhia nos grandes centros urbanos e o estreito convívio com o homem fazem com que haja um aumento no risco de zoonoses para a população humana. Ao oferecer exames parasitológicos gratuitos de fezes de animais domésticos, é possível realizar análises de rotina e acompanhamento da saúde dos animais, além de tornar possível a mensuração de quais são os agentes parasitológicos mais frequentes e quais constituem zoonose. Com objetivo de fornecer serviços gratuitos à comunidade que usufrui da clínica veterinária do Instituto Federal Catarinense – Campus Concórdia, amostras de fezes provenientes de cães e gatos, colhidas pelos tutores individualmente, foram identificadas e então colocadas em uma caixa com a identificação do projeto Exames gratuitos: Exames laboratoriais para cães e gatos fornecidos pelo LVP, sendo os exames realizados na mesma instituição, no Laboratório de Parasitologia Veterinária (LPV). Estas amostras foram submetidas aos métodos qualitativos de Willis; Hoffman, Pons & Janer e centrífugo-flutuação em solução de sacarose (d=1,203g/cm3). Foram examinadas 96 amostras, totalizando 238 exames parasitológicos. Foram diagnosticados 29 animais com parasitoses, nos quais foram encontrados ovos dos gêneros Ancylostoma, Trichuris, Cystoisospora, Giardia, Toxocara e Dipylidium. Além destes, outros parasitas foram acidentalmente encontrados nos exames de fezes, como o artrópode Demodex canis e ácaros. Os cães e gatos diagnosticados e devidamente identificados tiveram seus proprietários notificados. Levando-se em consideração os diagnósticos realizados pelo projeto, é notável que os exames auxiliam nos cuidados e na atenção à saúde do animal e consequentemente à humana.

Demodicosis is a parasitic disease caused by the imbalance in the number of mites of the genus Demodex sp. The skin scraping is the gold standard method for diagnosis, but other methods can be used. Based on this, the aim of this work is to report cases in which cytology served as an auxiliary diagnosis for demodectic mange. Two dogs went to a private clinic with skin lesion of different aspects and in which both dogs the cytology was performed by skin imprint, being possible to observe the presence of Demodex canis. Thus, cytology could be used as an auxiliary diagnostic method this disease.

Использование собак в сельском хозяйстве, особенно в животноводстве, временами является необходимостью и традицией в Чеченской Республике. Вместе с тем, ветеринарный контроль этой группы собак в большинстве случаев оставляет желать лучшего. Не редкость, когда в овцеводческих отарах и на отгонных пастбищах содержатся собаки, зараженные паразитарными заболеваниями. Результаты лабораторных исследований и клинические показатели осмотра дают основание диагностировать у собак демодекоз. Статистика распространения демодекоза у собак в условиях города и села показала высокую инвазированность в сельских районах (21,1%) и сравнительно низкую в городах (всего 10,0%).
