Aim:This study aims to determine the etiology of urinary tract infection (UTI) in dogs and to develop an antibiogram of organisms isolated.Materials and Methods:Urine samples were collected either through catheterization or cystocentesis from 35 dogs suspected of UTI admitted to VCC, LUVAS, Hisar. Bacteria were identified on the basis of cultural characteristics in 22 samples, and all the isolates were subjected to in vitro antimicrobial sensitivity testing.Results:The urine samples found positive for bacteria yielded pure colony growth in 77.27% and mixed growth in 22.73% samples, respectively. Escherichia coli (29.62%) and Streptococcus spp. (29.62%) were the most prevalent microorganisms followed by Staphylococcus spp. (22.22%), Klebsiella spp. (11.11%), Pseudomonas spp. (3.7%), and Bacillus spp. (3.7%). Overall, maximum sensitivity of isolates was found toward ceftriaxone/tazobactam (88.88%) and least toward amoxicillin and cloxacillin (29.62%).Conclusion:E. coli and Streptococcus spp. were the most predominant bacteria isolated from UTI affected dogs. In vitro sensitivity revealed a significant proportion of bacteria to be multidrug resistant.

Aim:Anaplasma marginale is a rickettsial pathogen responsible for progressive anemia in ruminants leading to huge economic losses. The objectives of this cross-sectional study were to determine the prevalence of anaplasmosis and therapeutic evaluation of traditional line of treatment.Materials and Methods:A total of 168 cattle presented to Teaching Veterinary Clinical Complex, Lala Lajpat Rai University of Veterinary & Animal Sciences, Hisar during the period of 3 months (July-September, 2014) with history of fever, anorexia, reduced milk yield and tick infestation were analyzed for prevalence of hemoprotozoan diseases using classical giemsa stained thin blood smear parasitological method.Results:Out of these 168 animals, 7 (4.17%) were found to be suffering from anaplasmosis on the basis of presence of dense, rounded, intra-erythrocytic bodies situated on or near the margin of the erythrocytes. Overall prevalence of theileriosis and babesiosis were found to be 42.9% and 1.8%, respectively. Level of parasitemia was noticed to be 1.2%, 0.8% and 0.9% in babesiosis, theileriosis, and anaplasmosis, respectively. The most marked and common clinical signs reported in all the cases were severe anemia (hemoglobin=3-6 g/dl) and history of fever, followed by normal body temperature. Following treatment with oxytetracycline parenterally along with supportive therapy out of seven cases six got recovered without any side-effects.Conclusion:The current study indicates the emerging status of anaplasmosis in this part of the country as during the past few years there are very few reports showing the prevalence of clinical cases of anaplasmosis. Treatment with oxytetracycline yielded excellent result showing recovery in most of the clinical cases.

Aim: To determine the etiology of clinical mastitis in Murrah buffaloes and to develop an antibiogram of organisms isolated. Materials and Methods:A total of 564 quarter milk samples of 144 buffaloes suffering from clinical mastitis received in Veterinary College Central Laboratory were inoculated on blood agar, MacConkey's lactose agar and sabouraud dextrose agar. Bacteria isolated were characterized to the species level and subjected to in-vitro antimicrobial sensitivity testing.Results: Out of 564 quarters examined for mastitis, 320 (56.73%) quarters were found culturally positive showing isolation of Staphylococcus aureus 140 (38.04%), Streptococcus dysgalactiae 112 (30.43%), Streptococcus agalactiae 13 (3.53%), Escherichia coli 74 (20.10%) and Corynebacterium pyogenes 29 (7.88%). On carrying antibiogram staphylococci and streptococci revealed high sensitivity towards chloramphenicol, gentamicin, amikacin and enrofloxacin. Streptococci showed high sensitivity towards ceftriaxone and cefaperazone also. E. coli was found highly sensitive to chloramphenicol and gentamicin. C. pyogenes was sensitive to the majority of antibiotics. Conclusion:S. aureus was the most predominant bacteria isolated from mastitis cases and irrespective of the isolates chloramphenicol was found to be most sensitive when tested in-vitro.

Aim:The present study was undertaken to ascertain the incidence and clinical vital parameters in cases of primary ketosis in Murrah buffaloes brought to teaching veterinary clinical complex, Lala Lajpat Rai University of Veterinary and Animal Sciences, Hisar and from adjoining villages of the district Hisar, Haryana, India.Materials and Methods:The investigation was conducted on 24 clinical cases (out of total 145 screened) of primary ketosis. The diagnosis was confirmed on the basis of clinical signs and significantly positive two tests for ketone bodies in urine (Rothera’s and Keto-Diastix strip test). Data collected were statistically analyzed using independent Student’s t-test.Results:Overall incidence of disease in these areas was found to be 16.55% and all the animals were recently parturited (mean: 1.42±0.14 month), on an average in their third lactation (mean: 2.38±0.30) and exhibited clinical signs such as selective anorexia (refusal to feed on concentrate diet), drastic reduction in milk yield (mean: 64.4±5.35%), ketotic odor from urine, breath, and milk and rapid loss of body condition. All the clinical vital parameters in ketotic buffaloes (body temperature, heart rate, respiration rate, and rumen movements) were within normal range.Conclusion:Primary ketosis in Murrah buffaloes was the most common seen in the third lactation, within the first 2 months after parturition with characteristics clinical signs and no variability in vital parameters. The disease has severe effect on the production status of affected animal.

Aim:This study aims to develop and to standardize a polymerase chain reaction (PCR) assay that will diagnose clinical as well as carrier state of the disease and to compare the results with conventional microscopy technique.Materials and Methods:A herd of crossbred cattle with the previous history of theileriosis in village Lahli, district Rohtak, Haryana, was selected for this study. A total of 29 blood samples were collected randomly from cows including five clinically ill cattle. Blood smears from all animals and lymph node biopsy smears from animal with swollen lymph nodes were examined microscopically after conventional Giemsa staining. Phenol chloroform isoamyl alcohol method was used for extracting DNA from blood. Previously published primers targeting cytochrome b gene sequence of Theileria annulata were used in the PCR assay that was standardized to use in the laboratory.Results:Out of 29 samples tested,18 (62.06%) were found positive for theileriosis by PCR assay, whereas only 10 (34.48%) samples were detected positive by conventional microscopic technique using Giemsa staining method.Conclusions:On the basis results of comparative studies, it can be concluded that PCR assay is a more sensitive than microscopic examination for detection of theileriosis. This can be attributed to the ability of PCR assay to detect small amounts of genomic DNA of T. annulata or low parasitemia in cows. Therefore, PCR assay can serve as a more sensitive tool to detect Theileria for detection of theileriosis even in asymptomatic carrier cattle which is important for the implementation of successful control programs.
