Different selective culture media were evaluated for isolation of Aeromonas spp. from 120 poultry meat samples. The recovery ofAeromonas isolates was highest fromAmpicillin DextrinAgar (89.39%), followed by Aeromonas Starch DNAse agar (68.18 %) andAeromonas isolation media (18.18 %).

Anthelmintic resistance against commonly used anthelmintics (ivermectin, levamisole, morantel and fenbendazole) was studied in naturally occurring gastrointestinal (GI) nematodes in adult sheep of unorganized sheep farms of district Ludhiana (Punjab). After qualitative and quantitative screening of faeces of 100 sheep, fifty sheep having eggs per gram of faeces (EPG) 500 were randomly selected and divided into five equal groups. Ivermectin @ 200 ìg/kg body weight and levamisole @ 7.5 mg/kg body weight, injected subcutaneously, in two different groups, were 99.08 and 98.17 per cent effective,respectively. Whereas, fenbendazole @ 7.5 mg/kg body weight and morantel citrate @ 6.0 mg/kg body weight, orally was 66.28 and 95.41 per cent effective and the fifth group was kept as untreated control with natural exposure to gastrointestinal nematodes. Hence, it was concluded that the naturally occurring GI nematodes of sheep were susceptible for ivermectin and levamisole, suspected for resistance against morantel citrate and were resistant to fenbendazole.

A study was undertaken to understand the variations in physiological parameters \{Rectal Temperature (RT), Respiration Rate (RR) and Heart Rate (HR)\} in eight lambs (Patanwadi and Marwari)and six kids (Surti). The parameters were recorded on day 0 (day of birth) and days 3, 10 and 30 of age.Rectal Temperature (ºF) was found to be significantly low in both lambs (102.41) and kids (101.97) at birth as compared to the values recorded at later stages. On day 3 of age, the rectal temperature values were significantly higher in lambs than in kids, but at par on other stages. Respiration rate (no./min) and heart rate were significantly high on the day of birth and day 3 of age in both lambs and kids and dropped significantly with advancing age. Heart rate in kids (295.67) was significantly higher than in lambs (255) on day of birth,only.

In the study, 348 bacterial isolates comprising of Escherichia coli (100), Klebsiella aerogens (45), Proteus mirablis (35), Peudomonas aerogens (20), Staphylococcus sp. (78), Streptococcus sp. (13), Bacillus sp. (57) were isolated from egg shell and egg contents of 150 egg samples collected from local market in Patna (Bihar). The isolates were subjected to antibiogram. This study demonstrated that egg from organized farm microbial contamination than unorganized poultry farm reflecting the effect of environment, storage and transportation on microbial quality of eggs.

The herd strength of the farm was 480 crossbreds containing 393 females and 87 males, out of which 43 females and 15 males suffered from fluorosis leading to overall prevalence of 12.08 %. It is revealed that overall prevalence in males (17.24 %) was higher as compare to the females (11.05%). The prevalence in males below six months of age group and in six months and above (adults) was recorded to be 16.66 % and 17.46 % respectively. The adults and calves were equally susceptible to fluorosis in both sexes while heifers were least susceptible (3.12 %). Genetic group wise studies concluded that,prevalence in Brown swiss 50 % + Holstein Frisian 25 % + Gir 25% (16.88 %), then comes Holstein Frisian 50 % + Gir 50 % (15.84 %), then (11.94 %) in Holstein Frisian 50 % + Jersey 25 % + Gir 25% and least (5.95 %) was recorded in reciprocal crosses. Clinical examination revealed two forms viz: osteodental fluorosis and osteofluorosis. The level of fluorine in serum samples ranged between 1.0 to 7.0 ìg/ml. Epidemiological investigation could not ascertain the source of fluorine intake. Drop in milk production, adverse effect on reproduction and evidence of hypothyroidism were not recorded in any animal. Aluminium sulphate @ 30 gms to 45 gms / day was given as a curative treatment while in chronic cases of fluorosis @ 20 gms/animal was given for 15 days keeping 7 days gap and again given for 15 days till there is improvement in clinical symptoms. There was no recurrence of clinical symptoms and no addition of new cases. __________________________________________________________________

Conventional methods of detecting Corynebacterium pseudotuberculosis, a bacterium that causes caseous lymphadenitis (CLA) in sheeps and goats focused on several serodiagnostic tests such as ELISA, Western blotting and various inhibition and precipitation techniques. This paper described a Surface Plasmon Resonance (SPR) protocol for the direct detection of polyclonal
antibodies against Corynebacterium pseudotuberculosis with immobilisation of the antigen on unmodified transducer surface. The lower limit of detection was determined to be 2 μg mL-1 of immobilised antigen (Ag). Sufficient binding interaction was monitored on unmodified transducer; and saturation of the binding interaction was observed at 80 μg mL-1 of interacted antibody.

The objective of this study was to examine the nutritionally-related
blood metabolites; total protein and glucose levels in goats of Kinta and Hilir Perak districts. A total of eight farms were screened, involving a total of 220 animals. Serum samples were collected in plain tubes for total protein determination, while
plasma samples were collected in sodium fluoride tubes for glucose determination. Total protein and glucose determination were carried out using Idexx Vettest 8008 Blood Chemistry Analyzer. Results show
that goats in seven out of eight farms had malnutrition problems and poor body scores. Farmers were given advices based on the laboratory results obtained from this study.

Strangles is an extremely contagious bacterial infection specific to
equine species( horses, mules and zebras). A nationwide screening of S. equi was conducted among horses following an isolation of Streptococcus equi subsp. equi (S. equi) from a horse. All horses were monitored for the presence of respiratory signs, nasal discharge and submandibular swelling. This paper reports the isolation of S. equi from horses during a nationwide survey from August 2010 to December 2010. From August 2010 to December 2010 our laboratory received 2,825 nasal swabs, 9 guttural pouch flushes, 1 submandibular swab and 1 submandibular abscess. The samples were subjected to conventional bacterial isolation and identification.
Streptococcus equi-positive samples were also confirmed by detecting the M-gene (SeM) of the bacteria by using PCR. Two nasal swabs from two horses and one submandibular abscess from a horse were positive for S. equi by culture and subsequently by PCR. Surveillance for S. equi should be continued for the control of the strangles. PCR can be carried out in parallel to bacterial culture to increase the
detection rate of carriers and shedders.

O objetivo deste estudo foi avaliar a maturação e o desenvolvimento embrionário após a fecundação in vitro de oócitos bovinos que tiveram a maturação bloqueada com Butirolactona I e Roscovitina em meio de pré-maturação suplementado com soro fetal bovino (SFB). Oócitos foram divididos em 4 grupos: Controle 0 hora, Controle (maturação por 24 horas), Butirolactona I (bloqueio da maturação com 150µM de Butirolactona I por 24 horas, seguido de 24 horas de maturação) e Roscovitina (bloqueio da maturação com 50µM de Roscovitina por 24 horas, seguido de 24 horas de maturação). Para avaliar a maturação nuclear, os oócitos foram fixados e corados em aceto orceína. Parte dos oócitos dos grupos Controle 24 horas, Roscovitina e Butirolactona I após o período de maturação, foi fecundado in vitro. O desenvolvimento embrionário foi avaliado pelos índices de clivagem (D3) e formação de blastocistos (D7). Oócitos do grupo Butirolactona I apresentaram índices de Vesícula Germinativa após o bloqueio e de Metáfase 2 após a maturação semelhantes ao dos grupos Controle 0 hora e Controle, respectivamente. Por outro lado, a Roscovitina apresentou menores índices de Vesícula Germinativa e Metáfase 2. Os grupos Controle e Butirolactona I apresentaram maiores índices de clivagens. O grupo Controle apresentou maior produção de blastocistos que o Roscovitina e não diferiu do grupo Butirolactona I. Conclui-se que a Butiroloactona I pode ser utilizada no sistema de pré-maturação em meio contendo SFB, pois apresentou resultados semelhantes ao do grupo Controle o mesmo não ocorrendo com a Roscovitina, que apresentou menores índices de maturação oocitária e de desenvolvimento embrionário. | This study evaluated the bovine oocyte maturation and embryo development after in vitro fertilization. The maturation of the oocytes was blocked using Butyrolactone I and Roscovitine using pre-maturation medium supplemented with fetal calf serum (FCS). The ocytes were divided in four groups: Control 0 hour, Control (24 hours of maturation), Roscovitine (maturation blockage with 50mM Roscovitine during 24 hours followed by 24 hours of maturation), and Butyrolactone I (maturation blockage with 150mM Butyrolactone I during 24 hours followed by 24 hours of maturation). The oocytes were fixed and stained with aceto orcein to evaluate the nuclear maturation. After the maturation period, the remaining oocytes of the Control group, Roscovitine, and Butyrolactone I were fertilized in vitro. Embryo development was assessed by the cleavage rate (D3) and blastocysts formation (D7). The Butyrolactone I group had similar rates of germinal vesical stage oocytes during blockage, and Metaphase 2 after maturation, comparing to Control group at 0 hour and Control group, respectively. On the other hand, the Roscovitine group had lower rates of vesical stage oocytes during blockage, and Metaphase 2 after maturation comparing to Control groups. After in vitro fertilization, higher rates of cleavage were observed in Control and Butyrolactone I groups. For the blastocyst formation rate, the Control group showed better results than Roscovitine group. In summary, Butyrolactone I group had similar results to the Control group, and for this reason, is suitable for pre-maturation of bovine oocytes using FCS. In contrast, Roscovitine group had lower oocyte maturation and embryo development.
