2009
Murmu, S. | Dass, L.L. | Sharma, A.K.
The study was conducted in 18 clinically healthy male dogs of about 1 year of age, weighing up to 12 kg and divided into three groups of 6 animals each. Bupivacaine alone, bupivacaine + hyaluronidase and hyperbaric bupivacaine were given epidurally at lumbosacral space @2 mg/kg. bwt. with a maximum dose of 3 ml in the animals of groups I, II and III, respectively. A significant increase (P0.01) in rectal temperature, heart rate and respiration rate was recorded at initial intervals of observation in all the groups and thereafter these values follow a declining trend in all groups consistently and reached to almost base line value at 120 min. of observation The alterations of glucose, serum urea nitrogen, aspartate aminotransferase and creatinine estimated at 1hr, 2hrs, 4hrs and 24 hrs were remained within physiological limits in all the groups.Therefore induction of regional anaesthesia with bupivacaine and its combination revealed no permanent alteration in the biochemical and physiological parameters hence it is safe and satisfactory anaesthesia.

Pathak, Rekha | Kushwaha, R. B. | Kumar, Sanjay
Clinico-physiological effects of Xylazine - Ketamine were evaluated in 12 clinical cases of uremic buffalo calves having urolithiasis. In group A, Xylazine -Ketamine were used at the dose rate of 0.05 mg/kg body weight and 2.5 mg/kg body weight respectively to create regional spinal anesthesia at the lumbosacral space in 6 buffalo calves. In group B, Xylazine and Ketamine at the same dose rates were used intramuscularly in 6 buffalo calves. Analgesia was then recorded at different regions by the pin prick method and scored on a scale and motor incoordination, sedation, complete duration of anesthesia, complete recovery and physiological parameters (heart rate, respiration rate and rectal temperature) were evaluated in both the groups at various intervals of time throughout the duration of surgery of Tube cystotomy. It was found that the animals of group B achieved a safer physiological peak values than animals of group A.

2009
Moshtaghi, H. | Garg, S. R. | Mandokhot, Usha V.
Survivability of Listeria monocytogenes in clay loam soil was examined at 30° C for a period of 35 days. The microorganism inoculated in soil steadily declined from 3.5 × 10 6 g -1 to 3.9 × 10 4 g -1 (P = 0.05) on 35 th days. Destruction of normal soil microflora by heat treatment resulted in marginal rise in 3.3 × 10 6 g -1 of L. monocytogenes to 4.2 × 10 6 g -1 during the first 7 days, followed by steady decline to 5.6 × 10 4 g -1 on 35 th days. Heat treated soil inoculated with lower concentration of L. monocytogenes (3.6 × 10 4 g -1 ) supported sharp rise in its population to 4.8 × 10 6 g -1 (P=0.05) during the first weak which gradually declined, but remained higher (6.1 × 10 4 g -1 ) than the initial load even on 35 th days. In non-sterile soil, the rise was less appreciable but L. monocytogenes maintained its levels (10 4 g -1 ) during the experimental period. Survivability of the microorganisms was also observed in the soil with added chicken manure, cattle manure or sheep/goat manure.

2009
Dutta, S. | Laha, R. | Roy, R. N. | Ghosh, A.
Abortion, still birth, premature birth and mortality of cross bred dairy cattle (Jersey × Tharparkar/Red Sindhi) were noticed in the organized dairy farm of National Dairy Research Institute, Eastern Regional Station, Kalyani, Nadia, situated in hot and humid climatic area nearer to the river Ganges of West Bengal, India. The history of the farm revealed newly introduction of pure bred dairy cattle and outbreak of FMD during mid March to mid April, affected about 34% cross bred cows. During investigation, intermittent rise of temperature (104°F -108°F), anorexia, rapid respiration, progressive deterioration of health of animals and loss of milk production were also noticed. On the basis of past history, twenty suspected animals were taken for disease investigation. Repeated visit of the farm and repeated examinations of blood smears were done to observe any haemoprotozoan infections. Twenty to thirty percent of those suspected animals were found positive for Brucella antibodies by STAT, plate agglutination test and MRT. After a massive screening of blood smears, during the visit of third time, ultimately one animal (Identification number JT614) was found positive for the presence of Trypanosoma evansi infections in Giemsa stained blood smears. The infected and all suspected animals were successfully treated with single injection of a mixture of quinapyramine sulphate and chloride @ 7.4 mg/kg body weight subcutaneously. As a prophylactic measure, a mixture of quinapyramine sulphate and chloride @ 7.4 mg/kg body weight subcutaneously were also administered to all suspected animals prevented further occurrence of the disease in this dairy farm. It can be concluded that the iAfection with T. evansi in this farm has happened in a condition of intercurrent diseases with environmental stresses.

2009
Jain, Lata | Kanani, A. N. | Kumar, Vinay | Joshi, C. G. | Purohit, J. H.
Firfty serum and fifty semen samples collected from cattle and buffalo bulls were subjected to ELISA and gB gene based PCR, respectively to detect antibodies in serum and viral DNA in the semen against BHV 1. Out of 50 bulls, 15 (30%) serum samples were detected positive by ELISA while 21 (42%) semen samples were positive by gB gene based PCR. While correlating the results of ELISA and PCR, some seronegative bulls revealed presence of viral genome in semen whereas few seropositive bulls could not reveal viral genome in semen, thus, suggesting application of combined serological assay and PCR assay to detect the presence of BHV-1 infection in bulls.
Mostrar más [+] Menos [-]Immunosuppression and Histopathological Changes in the Bursa of Fabricius in Chickens with Different Vaccine Schedules against Infectious Bursal Disease (IBD)
2009
Sudhakar Goud, K. | Sreedevi, B.
The level of antibody by ELISA,immunsosuppressive effect baes on the response of birds to Newcastle disease vaccination and damage to bursa of Fabricius by IBD vaccination were studied. The efficacy of six different IBD vaccination schedules were studied using intermediate and intermediate plus strains of vaccines either alone or in combination. In vaccinated groups, the sero-conversion of the vaccine virus was noticed during fourth week, reaching to the peak between eight to twelve weeks of age in different groups. Afterwards, there was a gradual decrease in the titres, by the end of 20th week (maximum period tested). There was no significant difference in the titres of different treatment groups. However, all the groups showed titres above protective level during the entire period of study. There was significant difference in bursa body weight (B-BW) ratios of vaccinated groups in comparison with control group. Histopathological studies of bursal sections revealed depletion of lymphoid follicles, presence of cystic spaces, edema and hemorrhages. The birds vaccinated with hot strain of IBD vaccine showed metaplastic changes, presence of foam cells with pronounced interfollicular fibrosis. The bursal scores were maximum in the groups vaccinated with hot strains of IBD vaccines.
