29The present study investigated the presence of endo-and ecto-parasites, and vector-borne pathogens, 30 in dogs from four islands of Greece. A total of 200 owned and sheltered dogs were examined with 31 different microscopic, serological and molecular methods. 32Of the examined dogs, 130 (65%) were positive for one or more parasites and/or vector-borne 33 pathogens. The most common zoonotic intestinal helminths recorded were Ancylostomatidae 34 (12.5%) and Toxocara canis (3.5%). Ninety-three dogs (46.5%) seroreacted to Rickettsia conorii. 35 Twenty-two (11%) of them were also PCR positive and 7 (3.5%) showed corpuscoles suggestive of 36 Rickettsia spp. on the blood smears. Nineteen dogs (9.5%) were seropositive for Ehrlichia canis, three 37 of them being also PCR positive. Dogs positive for Anaplasma phagocytophilum-Anaplasma platys 38 (1%), Dirofilaria immitis (0.5%) and Babesia canis (0.5%) were also found. Fleas and ticks were 39 recorded in 53 (26.5%) and 50 (25%) dogs and all specimens were identified as Ctenocephalides felis 40 felis and Rhipicephalus sanguineus sensu latu. Binary multiple univariate Generalized Linear Models 41 were used to investigate factors and clinical signs related to the recorded positivity, while the 42 association of specific signs with the pathogens was evaluated using tests of independence. 43 Knowledge of occurrence and impact of zoonotic parasites and vector-borne pathogens in dog 44 populations is crucial to prevent the infection in animals and people, and to control the risk of 45 spreading of these pathogens in endemic and non-endemic areas. 46 47 Author summary 48 Both owned and sheltered dogs can harbor a variety of intestinal and extra-intestinal endoparasites, 49as well as vector-borne pathogens and ectoparasites, of zoonotic concern. Dog shelters and stray dogs 50 are present in several touristic areas of Greece, including Sporades and Cyclades islands, where 51 tourists often bring their pets with them, likely travelling from non-endemic to endemic areas. The 52 present study has been carried out with the aim to evaluate the occurrence of the aforementioned 53 pathogens. Data obtained showed that they are present in canine populations of Greece, with 54 possibilities of infection for travelling dogs, which can also contribute to the spreading of zoonotic 55 vector-borne diseases, introducing new pathogens in previously non-endemic areas. For these 56 reasons, a constant monitoring of the epidemiological situation, improving control measures and 57 correct diagnostic approaches are of primary importance for the prevention of canine and human 58 infections, decreasing the spreading of potentially deadly pathogens. 59 60 61 62 65circulation of zoonotic infections are difficult to control. Because of a lifestyle that implies a low-66 grade of sanitary management, stray and free-roaming dogs are at high risk of becoming infected with 67 a wide range of pathogens. Consequently, they act as a permanent source of infection for vectors, 68 other animals an...

The present study investigated the presence of endo- and ecto-parasites, and vector-borne pathogens, in dogs from four islands of Greece. A total of 200 (123 owned and 77 sheltered) dogs were examined with different microscopic, serological and molecular methods. Of the examined dogs, 130 (65%) were positive for one or more parasites and/or vector-borne pathogens. The most common zoonotic intestinal helminths recorded were Ancylostomatidae (12.5%) and Toxocara canis (3.5%). Ninety-three dogs (46.5%) seroreacted to Rickettsia conorii .

Um achado hematológico comumente importante em pacientes veterinários com doença renal crônica (DRC) em estágios mais avançados é a anemia normocítica, normocrômica e não regenerativa, que acarreta inúmeros sinais clínicos, dentre eles: fraqueza muscular, letargia, anorexia e perda de peso. Sabe-se que vários fatores da DRC levam a anemia nos animais, dentre eles estão a baixa síntese do hormônio eritropoietina pelos rins, redução da meia vida das hemácias em consequência de um quadro urêmico e aumento do estresse oxidativo, deficiências nutricionais de substâncias envolvidas na eritropoiese (devido anorexia) e ulcerações de mucosas que levam a perda de sangue. O objetivo deste trabalho é relatar o caso de uma paciente canina, diagnosticada com doença renal crônica a qual apresentava um quadro de anemia normocítica, normocrômica e não regenerativa, onde optou-se pela instituição do tratamento com eritropoietina recombinante humana obtendo-se efeitos hematológicos benéficos, bem como melhora na qualidade de vida
