    The present paper is focused on designing and manufacturing a remote-control test bench for RPA\u27s brushless motors. The main components of the testing bench (structural, mechanical and electric components) are presented, how they are coupled, and the operating principle. The test bench is characterized by five emergency systems, one manual and four automated emergency systems that can stop the test under different conditions to avoid damaging the motor. To validate the testing bench, a SK3-5045 660 kV electric motor was selected along with a carbon fibre reinforced composite propeller. It was experimentally demonstrated that the test bench was fully automated, there were measured the propulsion force, current intensity, voltage, but also the consumed power of a motor intended for an RPA. The test results were used to determine the motorization performance and power consumption of an RPA designed with four electric motors (quadcopter type)

    This study describes granulocytic anaplasmosis in two dogs naturally infected with Anaplasma phagocytophilum. The 3-year-old dogs (male and female) came from the same household and were referred to the Faculty of Veterinary Medicine in Iasi for blood donation. They were subject to standard routine tests: haematology blood test, blood smear, and serological tests (VETSCAN® FLEX4 and IDEXX SNAP 4Dx Plus). The female dog had no medical problems, while the male dog experienced joint pain. The blood smear was negative for tick-borne pathogens, and the haematology findings indicated thrombocytopenia in both dogs, with the male dog also displaying eosinophilia. The two dogs were mildly positive in the ELISA tests for the detection of Anaplasma spp. antibodies; therefore, the blood samples were tested using the qRT-PCR method for Anaplasma platys and Anaplasma phagocytophilum. The qRT-PCR result was negative for A. platys, but it was positive for A. phagocytophilum. The treatment consisted of the administration of doxycycline for 28 days. In conclusion, the high number of cases with non-specific clinical signs, the different sensitivity and specificity of the immunochromatographic serological tests, as well as the possibility of confusing the morula during the cytological examination, make the molecular test mandatory for precise diagnosis

    In vivo study of conjugated diminazene aceturate for ichthyophthiriosis of farmed carp

    Get PDF
    The aim of this study was to explore the efficacy of a veterinary drug, Diminazene aceturate (4,4’-(1-Triazene- 1,3-dyil)-bis-(benzenecarboximidamide), in an inclusion complex with β-cyclodextrin as a suitable treatment for parasitic diseases caused by Ichthyophthirius multifiliis in farmed carp. The efficacy was determined by the reduction in the infection intensity. The complexes were prepared by the coevaporation method and were characterized by DSC and FTIR. The selected stoichoimetry for the chosen drug was 1:1. Administration of Diminazene aceturate and complex was carried out by including appropriate doses in animal feed. Our studies suggest that the Diminazene–β-cyclodextrin complex results in a reduction in the infection degree and decrease in the trophont size in the treated fish. The oral treatment of Diminazene aceturate in inclusion complexes may be an alternative to bath treatments in carp farming

    The immune response in canine and human leishmaniasis and how this influences the diagnosis- a review and assessment of recent research

    Get PDF
    Leishmaniasis is a widespread but still underdiagnosed parasitic disease that affects both humans and animals. There are at least 20 pathogenic species of Leishmania, most of them being zoonotic. The diagnosis of leishmaniasis remains a major challenge, with an important role being played by the species of parasites involved, the genetic background, the immunocompetence of the host. This paper brings to the fore the sensitivity of the balance in canine and human leishmaniasis and addresses the importance of the host’s immune response in establishing a correct diagnosis, especially in certain cases of asymptomatic leishmaniasis, or in the situation the host is immunosuppressed or acquired leishmaniasis through vertical transmission. The methods considered as a reference in the diagnosis of leishmaniasis no longer present certainty, the diagnosis being influenced mostly by the immune response of the host, which differs according to the presence of other associated diseases or even according to the breed in dogs. Consequently, the diagnosis and surveillance of leishmaniasis cases remains an open topic, requiring new diagnostic methods adapted to the immunological state of the host

    In vitro study of diminazene aceturate complex with Β-Cyclodextrin for ichthyophthirius multifiliis

    Get PDF
    The histophagous ciliate Ichthyophthyrius multifiliis can cause lethality in farmed carp brood (Cyprinus carpio) as well as other representatives. In the present study, an antiparasitic substance (diminazene aceturate) and its complex with a cyclodextrin were tested for its activity against this pathogen in vitro. The purpose of this paper is to highlight the therapeutic potential of diminazene and the enhancement by the β-cyclodextrin. Of these, the complex proved to be more effective (i.e., killed all parasites in a test period of 6-8 hours). Administration in filtered water suggests that these compounds can not be effective in bathing. In view of these findings, we will discuss the potential utility of chemotherapy as a strategy for controlling ciliatosis in farmed fish

    Sarcoptic mange in dog is a common parasitic dermatitis, especially in non-controlled, stray dogs that develop evocative clinical signs. The present study includes 48 dogs, with different backgrounds, both privately owned and dogs from shelters. We searched for predisposing factors for contacting sarcoptic mange, such as: age, sex, breed, source of contamination. Their age ranged from 1.15 months to 12 years (with more than a half being under 1 year old), they were mostly common or cross-breed dogs, and the sex ratio was almost equal, with 25 females and 23 males. All dogs were naturally infected with Sarcoptes scabiei, as confirmed by identification on the microscope of skin scrapings from different body areas. Furthermore, we aimed to have a general idea concerning the severity of infection with Sarcoptes scabiei in the dogs we studied. The dogs received a clinical score based on the evaluation of typical signs that appear in sarcoptic mange such as alopecia, erythema, scales/crusts and the extent of mange on the cutaneous surface on different body parts (head, trunk, legs, tail). The most affected body part was the head, followed by the trunk and the most scored sign was the extent of affected skin and alopecia. The treatment consisted in the administration of either afoxolaner (Nexgard®), twice at a monthly interval (2.7-6.9 mg/kg), either sarolaner (Simparica®), twice at a monthly interval (2-4 mg/kg), or doramectin (Dectomax®) 0.2 mg/kg, twice at 14 days interval

    The study has been realised in May 2016 having as purpose the observation of the onchosphere hatching process. The eggs of Raillietina spp. were aquired from feces belonging to Great Spotted Woodpecker (Dendrocopos major) that was naturaly infested. Initally, the samples were examined from a parasitological point of view using the Willis method. The egg concentrate has been obtained using the protocol described by VOGE and all. (1961) with some adjustments. The egg suspension was incubated at 30 oC for an hour. The hatching process of the oncosphere has been observed on the slide with the optical microscope (Motic B series) fitted with a Moticam 1000 camera, using the x400 magnification. Measuring has been realised with Motic Images Plus 2.0 software. The temperature of the slide in the moment of examination was 32oC. The whole hatching proces lasted 5 hours and went through the following stages: after half an hour the hexachant embryo has broken the basal membrane and entered the vitelline layer, the onchosphere was vigorously pushing and scraping the granular structure belonging to the vitelline layer, then the vitelline membrane and the egg shell was perforated after four and a half hours, thus completing the actual hatching process. After hatching, the onchosphere engaged in a series of swim-like motions in the liquid mass

    DEFICITUL DE FIER ŞI ANEMIA PRIN DEFICIT DE FIER – PROBLEMĂ GLOBALĂ DE SĂNĂTATE PUBLICĂ

    Deficitul de fier este definit ca o stare în care nu există un nivel corespunzător de fier necesar pentru a menţine funcţiile normale fiziologice ale organismului. Anemia este o problemă globală de sănătate publică, de proporţiile unei epidemii, care afectează atât ţările în curs de dezvoltare cât şi ţările dezvoltate, cu consecinţe majore pentru sănătatea umană, precum şi dezvoltarea socială şi economică. În prezent, deficitul de fier şi în special anemia prin carenţă de fier rămâne una dintre deficienţele nutriţionale cele mai grave şi importante din lume. Fiecare grupă de vârstă este vulnerabilă. Sugarii, copiii mici, preşcolarii şi adolescenţii prezintă un risc mai mare de a dobândi deficit de fier, de aceea Organizaţia Mondială a Sănătăţii (OMS) a elaborat un pachet cuprinzător de măsuri de sănătate publică care abordează toate aspectele legate de un deficit de fier şi anemia feriprivă. În încercarea de a diminua prevalenţa deficitului de fier şi a anemiei feriprive, Societatea Europeană de Gastroenterologie, Hepatologie şi Nutriţie Pediatrică (The European Society for Paediatric Gastroenterology Hepatology and Nutrition-ESPGHAN) a sintetizat în 2014 recomandările utilizate şi în prezent privind profilaxia marţială

    ALIMENTAŢIA DIVERSIFICATĂ – SCURTĂ TRECERE ÎN REVISTĂ A UNOR PRINCIPII CORECTE PENTRU O SĂNĂTATE PE TERMEN LUNG

    Nutriţia reprezintă totalitatea proceselor fi ziologice de asimilare şi degradare a alimentelor care au loc într-un organism, necesare creşterii şi dezvoltării. Se menţin de actualitate discuţiile asupra tendinţelor în alimentaţie, numeroase societăţi ştiinţifi ce şi comitete internaţionale dedicându-şi atenţia asupra impactului pe care alimentaţia corectă o are asupra creşterii şi dezvoltării armonioase, începând încă din viaţa intrauterină. Introducerea progresivă în alimentaţia sugarului, după vârsta de 4-6 luni, a alimentelor semisolide şi solide, ce înlocuiesc treptat prânzurile de lapte administrate anterior este cunoscută sub denumirea de alimentaţie diversifi cată (complementară). Ultimele recomandări ale Comitetului ESPGHAN (European Society for Pediatric Gastroenterology, Hepatology and Nutrition) privind momentul trecerii de la o alimentaţie exclusiv lactată la una care să conţină şi alte alimente sunt pentru intervalul de vârstă cuprins între săptămânile 17-26. O importanţă primordială o are complianţa şi colaborarea familiei cu medicii. Având în vedere posibilitatea ac - tuală de a accesa numeroase informaţii, uneori fără o bază ştiinţifi că, am considerat oportună o scurtă trecere în revistă a principalelor aspecte ale unei alimentaţii diversifi cate conform recomandărilor de specialitate

    VITAMINA D: IMPLICAŢII MULTIPLE, NOI PERSPECTIVE

    Get PDF
    Deficitul de vitamină D reprezintă o problemă globală de sănătate publică, la toate grupele de vârstă, provocată în principal de expunerea insuficientă la lumina soarelui, diete necorespunzătoare, absorbție şi utilizare ineficiente, cerințe crescute sau pierderi mai mari. Cunoscând implicațiile vitaminei D în organism şi perioadele sensibile de creştere şi dezvoltare, este important să se efectueze determinări biologice, pentru o profilaxie adecvată şi pentru a interveni prompt când apar modificări. Grupele de vârstă la care se recomandă administrarea vitaminei D sunt sugarii (indiferent dacă sunt alimentați natural, cu formulă sau alimentație complementară) şi adolescenţii. În afară de rolul binecunoscut al vitaminei D în metabolismul fosfo-calcic, se discută din ce în ce mai mult de implicarea vitaminei D în patogenia bolilor non-musculo-scheletice
