A Dirofilaria immitis, causadora da infestação pelo verme do coração (IVC) ou dirofilariose afeta os membros da família Canidae e ainda é um problema clínico mundial. Até o ano de 2009, acreditava-se que o Iraque fosse livre da dirofilariose, porém nessa ocasião a governadoria de Kerbala foi relatada como uma área endêmica de dirofilariose. Assim, o presente trabalho foi realizado para investigar a ocorrência da Dirofilaria immitis em cães policiais em uma academia de polícia do Iraque, estudar as alterações macroscópicas e histopatológicas em cinco cães mortos, bem como, identificar as espécies do parasita causador com o emprego da técnida de PCR. Trinta e nove cães policiais com 6 meses a 12 anos de idade foram incluídos no estudo. Amostras de sangue de cinco mililitros foram colhidas por animal, em tubos com EDTA e foram examinadas pelo método de Knott. A necropsia sistêmica foi realizada em cinco cães que haviamapresentado sinais clínicos severos de dirofilariose e espécimens dos seus tecidos foram enviados para o processamento histopatológico de rotina. Para a análise molecular dos vermes adultos de Dirofilaria spp, foi empregada a extração do DNA e a amplificação do gene cox1. Quinze de 39(38,46%) cães foram diagnosticados com uma microfilariase variável de moderada para severa. As alterações macroscópicas e histopatológicas foram acompanhadas por lesões generalizadas tromboembólicas sugestivas da ocorrência da síndrome da veia cava. A investigação de PCR confirmou que a D.immitis era a espécie presente no Iraque. A conclusão do estudo estabeleceu que o Iraque deve passar a ser considerado como uma nova área endêmica da dirofilariose. Além da infestação registrada nos casos descritos é provável que ela também esteja presente em outras regiões do Iraque. Os autores recomendam a realização de estudos epidemiológicos para investigar a ocorrência de D.immitis tanto nos cães locais bem como em cães importados em todas as governadorias do Iraque, para ser construído o mapa epidemiológico da distribuição da doença e implantadas as ações de tratamento e de um progrma preventivo. Ações de educação em saúde sobre a doença deverão ser dirigidas para os veterinários, tratadores de cães e para pessoas em geral que tenham contato com os cães, pois esta doença é uma importante zoonose. | Dirofilaria immitis, the cause of heartworm infestation (HWI) or dirofilariasis, affects members of the Canidae and remains a worldwide clinical problem. In Iraq, dirofilariasis was believed absent until 2009, when the Karbala Governorate was reported as an endemic area for canine dirofilariasis. Consequently, this study intended to investigate the occurrence of Dirofilaria immitis in police dogs in one police academy in Iraq and to study the gross and histopathological changes in 5 dead dogs, as well as to identify the species of the causative parasite using PCR technique. Thirty-nine police dogs, aged between 6 months and 12 years were included in this study. For the microfilariae investigation, 5 ml blood samples were collected from all dogs in EDTA tubes and examined by Knott’s method. The systemic necropsy performed in five dead dogs showed severe clinical signs of dirofilariasis and tissue specimens were sent for routine histopathological processing. For the molecular analysis, adult worms of the detected Dirofilaria spp. were used for DNA extraction andamplification of the cox1 gene. Fifteen of 39 (38.46%) dogs were diagnosed with moderate to severe microfilariasis. The dead dogs revealed typical severe clinical signs of dirofilariasis. Moreover, typical gross and histopathological changes were also seen, accompanied by generalized thromboembolic lesions, suggesting the occurrence of the caval syndrome. The PCR investigation confirmed that D. immitis was the species present in Iraq. In conclusion, this study establishes that Iraq is a newly reported endemic area for dirofilariasis. Moreover, the infestation occurring in these cases most probably happened inside Iraq. The authors recommend doing further epidemiological studies concerning the occurrence of D. immitis in local dogs as well as in the imported dogs in all Iraqi governorates to better understand the epidemiological map of this disease and to introduce an active treatment and preventive program. Awareness and education regarding this disease should be provided to the veterinarians, dog guiders and people in direct contact with dogs, as this disease is one of the important zoonotic diseases.

O linfoma é uma malignidade linfoide muito comum nos cães, mas o envolvimento cardíaco é raro. O linfoma cardíaco primário é definido como linfoma que envolve o coração, o pericárdio ou ambos, sendo classificado como forma anatômica extranodal. O presente relato descreve os casos de três animais com linfoma cardíaco, que apresentaram efusão pericárdica moderada a importante e tamponamento cardíaco, sendo a análise citológica da efusão consistente com o diagnóstico de linfoma cardíaco nos três animais. A avaliação anatomopatológica do tumor extraído do coração de um dos animais, após eutanásia, foi compatível com linfoma cardíaco. Os outros dois animais foram tratados com protocolo quimioterápico segundo Madison-Wisconsin e apresentaram sobrevida entre 6 a 8 meses. Por meio deste relato, ressalta-se a importância da citologia do líquido das efusões pericárdicas, para o diagnóstico e adequado tratamento e acompanhamento dos tumores cardíacos de cães e gatos. | Lymphoma is a very common lymphoid malignancy in dogs, but cardiac involvement is rare. Primary cardiac lymphoma is defined as lymphoma involving the heart, the pericardium, or both, and is classified as extranodal anatomical form. The present report describes the cases of three animals with cardiac lymphoma. All cases presented moderate to severe pericardial effusion and cardiac tamponade. The cytological analysis of the effusion was consistent with the diagnosis of cardiac lymphoma. The anatomopathological evaluation of the tumor extracted from the heart of one of the animals, after euthanasia, was consistent with cardiac lymphoma. The other two animals were treated with Madison-Wisconsin chemotherapy protocol and survived between 6 to 8 months. This report emphasizes the importance of pericardial effusion cytology for the diagnosis, appropriate treatment approach and monitoring of cardiac tumors in dogs and cats.

A região central do Brasil é caracterizada como uma área endêmica para erliquiose canina. Devido a isso, o presente estudo objetivou determinar a prevalência de infecção em cães e seus carrapatos R. sanguineus, coletados a partir do mesmo ambiente. As amostras de soro e DNA genômico de sangue de 20 cães e 299 carrapatos foram testadas por RIFI e PCR a fim de detectar anticorpos e DNA de Ehrlichia canis. Do total, 9 (45%) eram soropositivos para E. canis com títulos variando de 80 a 10240 e 6 cães (30%) positivos para Ehrlichia spp. por PCR. Cinco carrapatos de vida livre (2,89%; intervalo de confiança 95%: 0,94-6,62%), e 6 carrapatos fixados em cães (4,76%; IC 95%: 1,77-10,0%) foram positivos. A taxa de infecção foi semelhante entre ambos os grupos (P=0.395). As sequências parciais do gene dsb de 2 amostras de carrapatos foram idênticas entre si e 100% (350/350) idênticas à E. canis. Apesar das altas taxas sorológicas e moleculares de erliquiose canina em Cuiabá, a prevalência de carrapatos infectados foi menor que o encontrado emcães. Por outro lado, os carrapatos adultos podem permanecer infectados por tempo suficiente para garantir a infestação e infecção aos cães susceptíveis. | The central region of Brazil is known to be an endemic area for canine ehrlichiosis. Therefore, this study aims to determine the prevalence rates of E. canis infection in dogs and in Rhipicephalus sanguineus ticks collected from the dogs and their home environments. Serum samples and genomic DNA from the blood of 20 dogs and 299 ticks were analyzed by IFA and PCR assays in order to detect Ehrlichia canis antibodies and DNA. Nine (45%) of the 20 dogs were seropositive for E. canis, with titers ranging from 80 to 10240, and 6 dogs (30%) were positive for Ehrlichia spp. by PCR. Five free-living ticks were positive (2.89%, 95% confidence interval: 0.94-6.62%), as were six ticks attached to dogs (4.76%; 95% CI: 1.77-10.0%). The two groups showed a similar infection rate (P=0.395). Partial dsb DNA sequences of two samples from ticks were identical to each other and 100% (350/350 nucleotides) were identical to E. canis. Despite the high serological and molecular rates of canine ehrlichiosis in Cuiabá, the prevalence among infected ticks was lower than that found among dogs. However, adult ticks may remain infective much longer to ensure their infestation and infection of susceptible dogs.

O presente estudo avaliou vacas Brangus tratadas com doses únicas de hormônio folículo estimulante (FSH) submetidas a aspiração folicular após vinte e quatro horas, para avaliação da recuperação oocitária, fertilização in vitro e taxa de prenhez. Folículos superiores a três milímetros de diâmetro foram aspirados, 200 mg de FSH foram administrados dois dias depois e uma nova aspiração folicular foi realizada 24 horas após. Esses métodos foram efetivados três vezes a cada três dias. No controle, as aspirações foliculares ocorreram em intervalos de uma semana sem administração de FSH. Os oócitos aspirados foram avaliados, submetidos à fertilização in vitro e os embriões foram transferidos em receptoras. A recuperação média dos oócitos foi superior (p<0,05) nas vacas controle (12,4±1,8) do que nas vacas tratadas (9,4±1,3). Não houve diferença (p>0,05) na porcentagem média de oócitos viáveis (52,0±3,9 e 62,7±4,7%) ou na porcentagem média de embriões (41,4±4,8 e 41,5±4,2%) entre vacas controle e vacas tratadas, respectivamente. A porcentagem média de prenhez não diferiu (p>0,05) para as vacas controle (43,8±2,7%) e as tratadas (40,9±6,8%). Em conclusão, o tratamento com FSH não melhorou a recuperação de oócitos, a fertilização in vitro e o percentual de prenhez. No entanto, existe a possibilidade de várias aspirações foliculares consecutivas a cada três dias, concentrando a fertilização in vitro e o percentual de prenhez. | The present study evaluated Brangus cows treated with single doses of follicle stimulating hormone (FSH) subjected to follicular aspiration after 24 h to assess oocyte recovery, in vitro fertilization and pregnancy rate. Follicles exceeding 3 millimeters in diameter were aspirated, 200 mg of FSH was administered 2 days later, and a new ovum pickup was performed 24 h afterward. These methods were performed 3 times every 3 days. In control, follicular aspirations occurred at intervals of 1-week without FSH administration o. The aspirated oocytes were evaluated, submitted to in vitro fertilization and the embryos were transferred to the recipients. The average recovery of oocytes was higher (p<0.05) in control cows (12.4±1.8) than in treated cows (9.4±1.3). There was no difference (p>0.05) in the mean percentage of viable oocytes (52.0±3.9 and 62.7±4.7%) or the mean percentage of embryos (41.4±4.8 and 41.5±4.2%) among control and treated cows, respectively. The mean percentage of pregnancy did not differ (p>0.05) for control cows (43.8±2.7%), and treated cows (40.9±6.8%). In conclusion, FSH treatment did not improve oocyte recovery, in vitro fertilization, and pregnancy percentage. However, there is possibility of several consecutive ovum pickup every t3 days, concentrating the in vitro fertilization and the pregnancy percentage.

Este estudo avaliou a presença de anticorpos contra N. caninum e T. gondii em 320 cães domésticos das áreas urbana e rural do município de Poconé, no estado do Mato Grosso, região pantaneira do Pantanal. A Reação de Imunofuorescência Indireta (RIFI) foi utilizada para detectar anticorpos anti-N. caninum (ponto de corte igual a 50) e anticorpos anti-T. gondii (ponto de corte igual a 16) utilizando as cepas NC-Bahia e RH como antígenos, respectivamente. Anticorpos anti-N. caninum foram detectados em 69 (21,56%; IC 95%: 17,27%-26,56%) cães, dos quais 31 (44,93%) eram da área urbana e 38 (55,07%) eram da área rural e os títulos variaram entre 50 a 3200. Em relação aos anticorpos contra T. gondii 132 (41,25%; IC&nbsp;95%: 35,84%-46,87%) cães foram sororeagentes sendo que 58 (43,94%) eram da área urbana e 74 (56,06%) da área rural e os títulos variaram entre 16 a 8192. Um total de 33 (10,31%) (12 cães urbanos e 21 cães rurais) cães reagiram para ambos os agentes testados pela RIFI (P &lt;0,05). Este estudo mostrou uma maior ocorrência de anticorpos contra T. gondii em relação a N. caninum nos cães avaliados, mostrando que na região do Pantanal há circulação desses importantes protozoários. Essa informação é relevante dada sua importância para a saúde animal e pública. | Tis study evaluated the presence of Neospora caninum and Toxoplasma gondii antibodies in 320 domestic dogs living in urban and rural areas of the municipality of Poconé, located in the Pantanal wetlands of the state of Mato Grosso, Brazil.

International audience | Introduction: Infection of goats with caprine arthritis encephalitis virus (CAEV) has been detected in variable proportions in many countries all over the world. Here, we investigated the seroprevalence of CAEV in goats raised in Algeria. Material and Methods: A serological survey was performed on serum samples from 1,313 goats, including the local breeds (Arabia and Dwarf of Kabylia) and imported European breeds (Alpine and Saanen). Blood samples were taken from goats on 38 farms distributed across four different geographical regions of Algeria. Serum samples were tested for CAEV antibodies using a commercial ELISA. Results: A total of 390 serum samples were found to be positive for CAEV, giving an overall seropositivity rate of 29.7% in individual animals and 97.37% (37/38) at the goat farm level. Conclusion: These results provide the first large-scale serological evidence for the presence of CAEV infection in both the local and imported breeds of goats raised in Algeria, indicating that the virus infection is widespread.

International audience | Clinical indicators such as diarrhoea (DISCO) or anaemia (FAMACHA©) are used as a measure for targeted selective treatments against gastrointestinal nematodes (GIN). Enteric cestodes such as Moniezia may interfere directly with DISCO or indirectly with the FAMACHA© score. We investigated 821 Ouled Djellal rams naturally infected in a steppe environment (GIN alone, cestodes alone, GIN and cestodes) or not. The rams were treated with ivermectin 2 months before being slaughtered to reduce the impact of nematodes on the clinical scores; however, persistent or newly acquired GINs were not related to both scores. Of the non-infected rams (n = 296), 26% identified as needing treatment against GIN using the FAMACHA score, and 34.5% using DISCO would have been thus selected. This implies that the clinical indicators used for the targeted selective treatment of gastrointestinal nematodes are not fully reliable when a low infection is recorded and may well be influenced by confounding factors. As expected, only DISCO was affected by cestode infection, and we suggest that the presence of Moniezia should also be taken into consideration. | Des indicateurs cliniques tels que la diarrhée (DISCO) ou l'anémie (FAMACHA © ) sont utilisés comme mesure pour des traitements sélectifs ciblés contre les nématodes gastro-intestinaux (GIN).

peer reviewed | Objective: To explore feeding strategies and identify eventual errors that could cause poor pro-duction and reproduction performances in dairy farms in the north of Algeria.Materials and Methods: A survey was conducted among 211 farms of different sizes, from 2014 to 2018 to compose a database that is analyzed statistically.Results: The results relative to the nutritive value of the rations showed an average dry matter intake of 15.9 ± 4.74 kg/cow/day, providing 13.2 ± 4.34 UFL (Feed Unit for Lactation) of net energy and 1306 ± 456 gm of protein digested in small intestine (PDI)/cow/day. A high proportion of concentrate intake is observed, with an average of 64.7% ± 17.4% of energy intake and 70.2% ± 16.2% of nitrogen intake.Dairy cows performances were characterized by a low milk productionregarding their genetic potential (14.2 ± 4.73 kg of milk/cow/day), a calving interval > to one year (397 ± 20.4 days), though the coverage rates of their nutrient requirements reached 120%.The typology of the dietary rations allowed grouping them into three categories: deficient rations cluster (DR), correct rations cluster, and excessive rations cluster (ER). DR and ER, which are not adjusted to animals’ needs, were found in 57.8% of farms.Conclusion: It is obvious that the feeding management in the dairy farms in the North of Algeria is not based upon scientific achievements, contributing to relatively low performances of cows as well as to important financial losses. This finding imposes the necessity to adopt a correct and accurate rationing of animals.

Objective: To explore feeding strategies and identify eventual errors that could cause poor pro¬duction and reproduction performances in dairy farms in the north of Algeria. Materials and Methods: A survey was conducted among 211 farms of different sizes, from 2014 to 2018 to compose a database that is analyzed statistically. Results: The results relative to the nutritive value of the rations showed an average dry matter intake of 15.9 ± 4.74 kg/cow/day, providing 13.2 ± 4.34 UFL (Feed Unit for Lactation) of net energy and 1306 ± 456 gm of protein digested in small intestine (PDI)/cow/day.

peer reviewed | Objective: The present study was conducted to estimate the seroprevalence and associated risk factors of BoHV-1 in a dairy herd in the northeast of Algiers, Algeria. Materials and methods: The target area is in northeast of Algiers with humid to semi-dry climate and known for its economically important production of cattle. A total of 1066 randomly selected individual blood samples of dairy herd collected at 120 dairy farms from rural districts of northeast of Algiers were evaluated with antibodies against BoHV-1 using commercial ELISA kits, to determine the BoHV-1 infection status of the herds. A questionnaire submitted to the farmers during collection of the blood samples was used to collect data on potential BoHV-1 associated risk factors. Results: In the present study, the estimated farm and individual animal BoHV-1 seroprevalence levels were 58.33% and 14.16%, respectively. A logistic regression analysis of random-effects model revealed that the significant associated risk factors for the present farm and individual animal seroprevalence levels were rural district, cattle introduced to the farm, region, and hygiene. Conclusion: This study found higher seroprevalence of BoHV-1 in the northeast of Algiers. The results could be used in designing the prevention and control strategy of BoHV-1 in the northeastern part of Algeria.
