ABSTRACT
Thelaziosis is a vector-borne zoonotic disease with worldwide distribution, including in India and reports on canine ocular thelaziosis are very limited. The present case documentation will provide basic information to initiate the geographical epidemiological studies which will help to prevent the spread to these zoonotic diseases in the specified location. This communication reports about the rare case of canine ocular thelaziosis in Andhra Pradesh with the morphological features of the parasite and the management of ocular manifestations with suitable antimicrobial and anti-inflammatory eye drops along with ivermectin injections.
ABSTRACT
A 9 years old bull was presented to the hospital with a history of scrotal swelling for a period of 12 days and progressive emaciation with intermittent fever. Clinical examination revealed the swollen and painful scrotum with fluid thrill, mild abduction and disorientation of hindlimbs were noticed. Ultrasonography of the testes revealed the anechoic fluid in between the visceral and parietal layers of tunica vaginalis of testis with variation in the echogenicity of the testes. Stained peripheral blood smear examination revealed the presence of Trypanosoma evansi organisms. The bull was administered with diminazene aceturate, enrofloxacin, flunixin meglumine, multivitamin injections and dextrose normal saline. Uneventful recovery was noticed following the therapy.
ABSTRACT
Present study was aimed to record the Toxocara spp. eggs in dog's hair and to analyze the incidence in breed and age wise along with incidence variations in the anatomical locations of hair over the body. Dogs presented to the hospital were screened for enteric parasitic ova and hair samples were collected from the different body regions including head and neck region, ventral and lateral abdomen, perianal and hindquarters and tail region. Out of the 236 dogs, 124 (52.54%) dogs showed Toxocara spp. eggs in the faecal samples and 60 (25.42%) showed the presence of Toxocara spp. eggs on their hair. It was noticed that the dogs with long hair showed (36.73%) more incidence than the short hair breeds (17.39%). The incidence of the Toxocara spp. eggs were varied with the presence of the hair at different anatomical locations and it was 36.67% in the head and neck region, 51.67% ventral and lateral abdomen, 86.67% in perianal and hindquarters, 56.67% in the tail region. 25.35% of the dogs were under 1-year-old, 25.98% dogs were between 1 and 6 years old and 23.68% dogs were more than 6 years had the Toxocara spp. eggs in their hairs. In conclusion, the presences of Toxocara spp. eggs in the hair of different breeds of dogs were recorded in the present geographical location and it is a zoonotic alert for the pet owners.
ABSTRACT
Capillaria spp infection was diagnosed in a 3 year old dog with history of pollakiuria, dysuria and haematuria. Confirmatory diagnosis was done by demonstration of the parasitic ova in the urinary sediment, cystitis by ultrasonography, presence of proteins and leukocytes in the urine. Dog was successfully treated with fenbendazole and ivermectin along with supportive therapy. Recovery was noticed after 2 weeks of treatment with clear and transparent urine and absence of parasitic ova in urinary sediment.
ABSTRACT
In the present case, jugular vein engorgement and oedema of the brisket region which mimic the signs of pseudopericarditis due to theileriosis in a bull was reported. An adult Ongole crossbred bull with history of weakness, anorexia and oedema at brisket region was referred to Teaching Veterinary Clinical Complex, College of Veterinary Science, Proddatur. Physical examination revealed the presence of ticks over the body, right and left prescapular lymphadenopathy and oedema at brisket region. Blood examination revealed the presence of piroplasms in erythrocytes, schizont in lymphocytes, anaemia and lymphopenia. Bull was treated with injection buparvaquone along with supportive medications. By the 3rd week of therapy improvement was noticed by disappearance of brisket oedema and recurrence was not noticed during the 8 months of observation.
ABSTRACT
Demodicosis was diagnosed in a cattle based on dermatological lesions and examination of skin scrapings. The cattle had anaemia, leucocytosis, eosinophilia and neutrophilia. Cattle was treated with strepto penicillin, ivermectin, amitraz along with supportive therapy. After 2 months of therapy clinical cure and regrowth of hair was noticed.
ABSTRACT
The field isolates of Trypanosoma evansi was collected from the infected cattle and it was propagated in rats. Trypanosoma evansi parasites were separated from the blood of infected rats by using diethylaminoethyl cellulose column chromatography. Whole cell lysate antigen (WCL) was prepared from purified trypanosomes by ultrasonication and centrifugation. The prepared WCL antigen was further purified by 50 % ammonium sulphate precipitation. Protein concentration of WCL antigen of T. evansi was 60 mg/ml. Protein concentration was adjusted to 1.0 mg/ml in PBS, pH 8.0 and stored at -20(0) C. Polypeptide profiles of WCL antigen of T. evansi was determined by sodium dodecyl sulphate polyacrylamide gel electrophoresis. A total of eight polypeptide bands of the size ranging from 25 to 85 kDa in WCL antigen of T. evansi were obtained. Five prominent bands with molecular weight of 74, 60, 53, 42 and 37 kDa and three light bands with molecular weight of 85, 34 and 25 kDa were observed.
ABSTRACT
Present study reports the effect of deltamethrin against louse infestation in domestic pigeons. In this study, twelve pigeons infested with Columbicola columbae louse were sprayed with deltamethrin (12.5 %) and another twelve pigeons were kept as control group. The lice intensity was reduced 89 %, 98 % and 100 % on 1st, 7th and 14th day of post treatment in treatment group. Out of twelve pigeons, four pigeons showed sneezing and temporary ocular inflammations after spraying.
ABSTRACT
Hepatic coccidiosis is a contagious and lethal disease condition in rabbits. The disease was recorded in six rabbits suffering with watery diarrhoea. Clinically, affected rabbits showed decreased growth rate, anorexia, debilitation, diarrhea and rough hair coat. Examination of the faecal samples revealed the presence of unsporulated oocysts of Eimeria spp. After sporulation Eimeria stiedae oocysts were identified. Postmortem examination revealed hepatomegaly with presence of discrete yellowish-white nodules on the surface of the liver. Impression smears from the liver revealed the presence of numerous developmental stages of E. stiedae corresponding with the stage of the liver lesion and also represent the histological changes of the liver. Rabbits were treated with a combination of sulphaquinoxaline and diaveridine for five days.
ABSTRACT
Canine babesiosis is a worldwide tick borne disease. Dogs with fever, in appetence and enlarged lymph nodes were screened for the presence of haemoprotozoan parasites during the one year period of study at T.V.C.C., C.V.Sc., Proddatur. Based on the stained peripheral blood smears examination, six dogs were found to be affected with babesiosis. Clinical examination of the dogs revealed ticks over the body, congested conjunctival mucus membranes, dullness, fever, tachycardia, tachypnoea in all the dogs. Some of the dogs had icterus, lymphadenopathy, haemoglobinuria. Laboratory examination of the clinical samples revealed reduction in haemoglobin concentration, erythrocyte count, platelet count, serum total protein, serum albumin and glucose levels. Increased serum SGPT, creatinine, BUN levels were recorded. Dogs were treated with inj. Diminazene aceturate (Berenil RTU) @ 5 mg/kg body weight, single dose along with supportive and symptomatic therapy in individual cases.
ABSTRACT
In one year period of study, dogs with inappetence, fever, ocular discharges, dullness, enlarged lymph nodes were screened for the presence of haemoprotozoans at College Hospital of College of Veterinary Science, Tirupati. Wet blood film examination and stained blood smear examination was done to confirm the condition. Peripheral blood smears of dogs revealed the presence of Trypansomes. Trypanosoma evansi was confirmed based on the morphology and measurements of the organisms in the stained blood smears. Haematology revealed decreased total erythrocyte count, packed cell volume, haemoglobin and total leucocyte count values. Total serum proteins, albumin and glucose levels were decreased significantly (P < 0.01), but a significant increase (P < 0.01) in cholesterol, blood urea nitrogen, serum alkaline phosphatase, serum aspartate aminotransferase and serum alanine aminotransferase levels were observed. Decreased total T4 and free T4 were also observed in the T. evansi infected dogs.
ABSTRACT
The diagnosis of Trypanosoma evansi in animals with low parasitaemia is hampered by low diagnostic sensitivity of traditional detection methods. The present study was undertaken with an objective to improve the diagnostic tools for detection of antibodies against T. evansi infection using indirect enzyme-linked immunosorbent assay (ELISA) in bovines. The optimum concentration of antigen, test sera and conjugate were determined as 5 µg per well, 1:10 and 1: 6,000 dilutions, respectively. Among 320 cattle and 382 buffaloes examined in different parts of Rayalaseema region of Andhra Pradesh for T. evansi infection, 36.12 and 31.87 percent were found positive by indirect ELISA, respectively.
ABSTRACT
Two mongrel dogs aged between 7 and 9 months in a same house were presented to the clinics with a history of chronic dermatitis associated with pruritus. Clinical examination revealed presence of primary and secondary skin lesions on the face, around the ears, chin, neck, fore limbs and lateral abdomen. Examination of skin scrapings revealed Demodex cornei (majority) and D. canis (minority) in both the dogs. By using hair pluck examination D. canis were detected and by tape impression smears examination large number of adult short-tail Demodex mites were found. D. cornei was identified by based on the morphological characters including short opisthosoma with blind and round terminal end. Mean length of total body, opisthosoma of both types of the mites were differed statistically significant (P < 0.01) but gnathosoma and podosoma did not differ significantly (P > 0.05). Dogs were treated with daily oral ivermectin @ 500 µg/kg/day, external application of amitraz along with supportive therapy. After completion of 45 days of therapy dogs were recovered completely without any side effects.
ABSTRACT
Coccidiosis is caused by the protozoan parasite belongs to the genous Eimeria spp. which parasitizes the epithelium lining of the alimentary tract. Infection damages the lining of the gut causing diarrhoea and possibly dysentery. Coccidiosis is primarily a disease of young animals but can affect older animals that are in poor condition. In a farm, seven adult cattle had foul smell bloody diarrhoea, anorexia, emaciation condition, smudging of the perineum and tail with blood stained dung. Laboratory examinations of the dung samples revealed the presence of coccidian oocysts. Animals were treated with 33.33 % (w/v) sulphadimidine, along with supportive and fluid therapy. After completion of 1 week of therapy all the affected cattle were recovered from the diarrhoea.
ABSTRACT
New Zealand white rabbits (N = 4) were challenged with the local strain of Trypanosoma evansi. Each rabbit was infected with 5 × 10(5) trypanosomes subcutaneously. The infection was characterized by intermittent pyrexia, undulating parasitaemia, anorexia and emaciation. The infected rabbits were examined daily for development of clinical signs and infection status by wet blood-films made from the ear veins. Thick and thin blood smears were also examined daily until the end of the experiment for description of blood cells. Differential leukocyte count (DLC) was also done. The parasite was observed in the blood during the acute phase only. Leukocytosis in the acute phase followed by leukopenia during the chronic phase was recognized. Haematological studies revealed reduced TEC, Hb and PCV. The main changes in the erythrocytes were macrocytes, hypochromic cells, Howell-Jolly bodies, target cells, stomatocytes and burr cells. Serum chemistry revealed hypoproteinemia, hypocholesterolaemia, hypoglycemia, hyperbilirubinemia, elevated creatinine, BUN, increased AST and ALT.
ABSTRACT
Notoedres cati was observed in two domestic cats. Cats exhibited crust formation, hyperkeratosis, alopecia and intense pruritus. Distribution of lesions observed at the ear margins, face, and legs. Owners also had intense pruritus over the hands, small erythematic crusted papules on the wrists and both the legs. Laboratory examination of skin scrapings from the cat revealed the presence of ova, adult mites of N. cati. The infected cats were treated with weekly twice oral administration of ivermectin at 200 µg/kg body weight, oral administration of 2 ml of multi-vitamin and mineral syrup daily. Improvement was noticed by complete clinical recovery along with absence of mites in skin scrapings, after completion of four doses of oral ivermectin along with supportive therapy.
