ABSTRACT

A 1.5 year old Labrador retriever bitch was presented with the history of anorexia, depression, vomiting, diarrhea and involuntary movement of jaw. On clinical examination the bitch, it was found to have a fever 1040F, heart beat (140 bpm) with no cardiac arrhythmia, respiration 54 bpm, CRT < 3 second. Scanty nasal discharge and serous ocular discharge with blepharitis and cloudiness of eyes, distemper myoclonus and hyper keratinization of foot pad was also found. On the basis of clinical signs and lymphopenia shown in blood report, the disease was diagnosed as canine distemper. The treatment of the animal was done symptomatically and prophylactically. Treatment was found to be effective and animal was recovered up to some extent after 15 days; however, nervous signs were still there.

A 1.5 year old Labrador retriever bitch was presented with the history of anorexia, depression, vomiting, diarrhea and involuntary movement of jaw. On clinical examination the bitch, it was found to have a fever 1040F, heart beat (140 bpm) with no cardiac arrhythmia, respiration 54 bpm, CRT < 3 second. Scanty nasal discharge and serous ocular discharge with blepharitis and cloudiness of eyes, distemper myoclonus and hyper keratinization of foot pad was also found. On the basis of clinical signs and lymphopenia shown in blood report, the disease was diagnosed as canine distemper. The treatment of the animal was done symptomatically and prophylactically. Treatment was found to be effective and animal was recovered up to some extent after 15 days; however, nervous signs were still there.

There is no specific anti–viral drug for this disease so symptomatic treatment was done (http://dogtime.com/distemper–in–dogs–vin.html). The treatment included anti–pyretic (inj. ketoprofen @ 2mg/kg) to reduce the fever, 3rd generation broad spectrum anti–biotic (inj. Ceftriaxone sodium @ 25mg/kg b.w) to avoid secondary bacterial infection. To check diarrhea and dehydration inj. Metronidazole @ 10mg/kg b.w and inf. ringer lactate @ 15ml/kg b.w was given respectively. From 2nd day to onward, with fluid therapy Ketoprofen syrup) @ 2mg/kg b.w once a day, Cephalexin (Keflex syrup) @15mg/kg 2 times a day and gravinat syrup @ 3mg/kg b.w afted feeding was recommended. A multi–vitamin powder (Bendoz powder) was added in feed @ 10g/day to support the animal. Same treatment was repeated for 3rd, 4th and 5th days.Vita A also play an important role for the treatment of canine distemper but mechanism is still unknown (Rodeheffer et al., 2007).


Morbillivirus of family Paramyxoviradae is the causative agent of an infectious disease of carnivore known as Canine distemper can also effect the vaccinated animals. At age of 6–8 month the disease most likely to occur depends on breed of animal (Chappuis, 1995). Not only canine the members of family Mustelidae and Procyonidae also susceptible (Appel, 1987). Most of times the recently weaned pups get this infection because at this stage the maternal immunity that is coming from milk are at its lowest level (Shabbir et al., 2010). Therefore it is recommended to vaccinate the dogs at 3 month of age.

Depending on the age and immune status of host incubation period varies between 1–4 weeks of different strains. About 50% mortality is seen in this disease without clinical signs to severe clinical signs (Appel, 1970, 1987; Krakowka et al., 1980; Moritz et al., 2000). As cold environment favors virus so the disease mostly occur in winter season. High mortality is seen is 63 % in under 1.5 of age in distemper encephalitis cases (Swango, 1989). All body secretions or excretion will contain virus in acute cases. In this case fever, cutaneous rashes, anorexia, diarrhea blisters on the abdominal region ocular and nasal discharge which is serous in nature along with conjunctivitis, blephritis and cloudiness of eye mostlvisible. Gastrointestinal signs become complicated when secondry infection occur. Progressive neurological signs are seen (Greene and Appel, 1998). Myoclonus, ataxia, plegia, and nystagmus are includes in nervous signs (Amude et al., 2007).

CDV main targets are mucous membranes and lymphoid tissue (Appel, 1987). This virus enter in body by air to URT and there in lymph nodes it primarily replicate and causes immunosuppression then spread to epithelium and CNS at about 10 days after transmission (Krakowka et al., 1980). Mainly cause lymphopenia in initial stages. When it reaches to lower respiratory tract (LRT), gastrointestinal tract and CNS cause lesions to be formed on these organs and responsible for appearance of systemic, cutaneous and nervous signs (Greene and Appel, 1998). Out of all CNS inflammation 15% of deaths of dogs caused by encephalomyelitis produce in Canine distemper (Appel and Summers, 1995).CDV produce encephalitic lesions and multifocal demyelination in CNS instead of inflammatory changes cause death of dogs after passing of systemic phase (Beineke et al. 2009).

Presence of distemper myoclonus (Figure 2) and hyper keratinization (Figure 1d) and lymphopenia in blood report confirm the disease as Canine Distemper. Because myoclonus and keratinization of foot pad are considered as the pathognomonic signs of this disease (http://www.2ndchance.info/dogdistemper.htm).

Animal can recover if promote the production of anti–bodies against the virus. But in footpads and lymphatic cells, this virus can persist and cause hyper keratinization (Appel, 1970, 1987; Greene and Appel, 1998) Due to this reason this disease is also called as hard pad disease.

At this time the only thing that we can do to prevent this disease is vaccination. By vaccination at regular intervals will help us a lot to control this disease until the specific treatment is not discover.
