Prevalence and Clinical Characteristics of Ehrlichia Canis Infection in Dogs in Thua Thien Hue

Abstract

The survey was carried out at OKADA PET Veterinary Center, Hue City, with 935 dogs of different ages and breeds. The results show that 39.6% of dogs have the clinical signs of Ehrlichia canis (E. canis) infection, 95.7% of which were serologically positive for E. canis antibody. The results also indicate that 54.9% of dogs have E. canis morulae in monocytes and/or neutrophils. Statistical analysis reveals that the prevalence of E. canis infection in dogs is not affected by breed, gender or age. The clinical symptoms of infected dogs are very complex, including fever, abortion, joint pain, breast tumours, short breathing, nasal haemorrhage, weakness, pale mucosa, skin inflammation, hair loss around the eyes, eye discharges, cloudy eyes, refuging to eat, diarrhoea, belly skin haemorrhage, anorexia, constipation, ascites, vomiting, depression, salivation, and metritis. About 37.9% of dogs are serologically infected with Ehrlichia canis with various symptoms.

Most common vector-borne diseases in dogs in Europe: a review

“…Consequently, it was also known as 'tracker dog disease' and 'tropical canine pancytopenia' . The infection was then discovered in other locations around the world, including the United States, countries in South America, Africa, and Asia (Hai, Khuong, 2021). The infection primarily affects the leukocytes (monocytes, macrophages, and neutrophils) of the mammals as well as the salivary gland, the gut, and hemocoel cells of tick.…”

“…All dog breeds can contract E. canis, but German shepherds seem to be more vulnerable because this breed exhibits more severe form of the disease and has a greater morbidity and mortality rate compared other breeds (Harrus, Waner, 2011). In other studies, it was demonstrated that the risk of E. canis infection does not depend on the breed (Hai, Khuong, 2021). Due to the several phases and numerous clinical presentations of the disease, diagnosis can be difficult.…”

“…The most noticeable haematological change that takes place during the acute period is thrombocytopenia (Harrus, Waner, 2011). Pale mucosa, skin inflammation, eye discharges, clouded eyes, hair loss around the eyes, diarrhoea, belly skin bleeding, constipation, ascites, vomiting, salivation, and metritis are some of the symptoms (Hai, Khuong, 2021). Pancytopenia brought on by the suppression or devastation of bone marrow characterises the chronic phase of the disease.…”

“…A tick communicates with its vertebrate host while it feeds over protracted periods of time. By suppressing the immunological response and tying up any antibodies the host may have produced in an effort to get rid of the blood-sucking parasite, it can weaken the immune system of the host (Hai, Khuong, 2021).…”

Effect of different nitrogen levels on yield and yield attributes of okra (Abelmoschus esculentus L.)

“…The following make up each 100 g edible portion of okra pods: Ca 84 mg, P 90 mg, Fe 1.2 mg, water 88.6 g, energy 144 kJ (36 kcal), protein 2.1 g, carbohydrate 8.2 g, fat 0.2 g, fibre 1.7 g, ascorbic acid 47 mg, thiamin 0.04 mg, riboflavin 0.08 mg, niacin 0.6 mg, and β-carotene 185 μg (Sorapong, 2012). The young immature okra pod is consumed as a nutritious dish in a variety of ways (fresh, boiling, dried, or fried), and the seed is used to make oil (Hai & Thao, 2022). The fruits are picked and eaten like vegetables when they are immature (Singh et al, 2014).…”
