ISOLATION, IDENTIFICATION AND ANTIBIOGRAM OF Pasteurella multocida ISOLATES OF RABBITS SUFFERING FROM PASTEURELLOSIS

Abstract

Isolation of Pasteurella multocida was attempted from the heart blood, spleen, liver and lung collected from rabbits (4 No,s) suspected to have died of pasteurellosis. A total of four P. multocida isolates were isolated and identified on the basis of biochemical characteristics, pathogenicity studies in mice and PM-PCR. The In vitro antibiotic sensitivity test of the organisms was conducted which revealed that all the four isolates showed sensitivity to Gentamicin and Oflaxacin. Three of them were sensitive to Enrofloxacin and Ciprofloxacin. Two isolates showed sensitivity to Doxycycline and Chloramphenicol. Only one isolate was found sensitive to Nalidixic acid. All the isolates were resistant to Doxycycline, Erythromycin, Neomycin, Ampicillin, Penicillin, Cephalexin and Poymixin B. Based on the antibiotic sensitivity test, Gentamicin was recommended as a drug of choice for the treatment of Pasteurellosis in rabbits and the disease was controlled.

Rare Outbreak of Fowl Cholera in Waterfowls in Dal Lake Area of Kashmir, with Isolation, Antibiogram and Successful Treatment - A Report

“…Pasteurella multocida has been isolated from the heart blood, spleen, liver and lung collected from turkeys and chicken, suspected to have died of avian pasteurellosis (Balakrishnan and Roy, 2012). The biochemical tests were positive for indole production, oxidase and catalase production coinciding with the earlier findings of Quinn et al, (1994) and Kawamota (1990).…”

Correlation analysis of seed yield and its components in chickpea (Cicer arietinum l.) genotypes

“…The highest estimate of heritability was found for pods per plant 74.2% followed by plant height 65.8% while lowest for days taken to maturity 48.8% followed by biomass per plant 47.1% 2,11,13 . The estimate of genetic advance was found for pods per plant 8.5906% followed by plant height 3.9001% while lowest for primary branches per plant 0.088% followed by seeds per plant 0.0686% 5,6,15,18,17 . The higher estimates of heritability and genetic advance indicated that the selection on the basis of these traits may be useful for the improvement of yield.…”

“…A negative and significant association occurred between the days to maturity with plant height, seeds per pod, and 100-seed weight. Grains per plant were positively and significantly correlated with days to maturity 1,3,6,24,29,16 .…”

“…Genotypic and phenotypic correlation coefficient between 100-seed weight and grain yield per plant and secondary branches per plant was negative and significant. Positive and non-significant correlation of 100-seed weight was found with days taken to flowering both at genotypic and phenotypic levels but negative and non-significant with all other traits 2,3,6,20,23 . A positive and significant genotypic and phenotypic correlation of pods per plant with biomass per plant, days taken to flowering, and primary branches per plant but highly significant genotypic correlation with biomass per plant.…”

“…It is evident from the result (Table-2) that the correlation coefficients of biomass per plant with pods per plant, primary branches per plant, secondary branches and plant height were positive and significant at phenotypic level and genotypic levels. It exhibited negative but non-significant correlation days taken to flowering, plant height, primary branches per plant and days taken to maturity at genotypic and phenotypic levels 1,6 . Biomass per plant has negative genotypic and phenotypic correlation but non-significant association was with 100-seed weight 24,26,28 .…”
