    2D and M-Mode Echocardiographic evaluation of dogs with canine heartworm (Dirofilaria immitis) infections [manuscript]
    (2018) Mikko Angelo G. Reyes
    The study evaluated the cardiac functions of dogs infected with Dirofilaria immitis infection, using 2D and M-mode ultrasonography. A total of 15 heartworm positive adult dogs tested using MCT, aged 3.8+2.62 years old, weighed 9.78+4.99kg, with body composition score of 4.73+1.06 were examined. Among the 15 animals only six (40%) have clinical symptoms, animals are then prepared for ultrasonography evaluation. Adult canine heartworms (HW) were visible as two parallel lines separated by a very thin hypoechoic center located within the right pulmonary artery. Sometimes extending to the main pulmonary artery and right ventricle. HW was visible only in ten (60.67%) dogs with varying worm loads. The results of this study showed that there were alterations in some chamber measurements and functions and right pulmonary artery distensibility index of heartworm positive dogs based on their body weight and the established reference values.

    Detection of Abortifacient bacterial agents of water buffaloes (Bubalus bubalis) in selected cities and municipalities of Nueva Ecija [manuscript]
    (2018) Noel M. Salvador
    The detection of presence of abortifacient bacterial agents in Nueva Ecija was the focus of this study. Specifically, it detected the presence of abortifacient bacterial agents’ Leptospira sp. And Brucella sp. in buffalo within selected cities and municipalities of Nueva Ecija with history and/or current abortion cases using nested Polymerase Chain Reaction (nPCR) and Rose Bengal Plate Test (RBPT), and determined the positive rate of Leptospirosis and Brucellosis in Nueva Ecija. A total of one hundred (100) serum samples and one hundred (100) urine samples from randomly selected buffaloes were collected for this study. Urine samples for Leptospira sp. were subjected to DNA extraction protocol and amplification using nPCR assay. The nPCR product were subjected to gel electrophoresis and viewed under UV transilluminator to confirm the presence of DNA bands lined at approximately 730 base pair. Serum samples for Brucella sp. were subjected RBPT, and was observed for the presence of antibody through agglutination reaction. Results revealed that the positive rate of Leptospirosis in Nueva Ecija was 7%. The positive animals identified were from the municipality of Carranglan (3/15; 20%), Science City of Munoz (2/14; 14.28%) and San Jose City (2/15; 13.33%). The positive rate of Nueva Ecija for Brucellosis was 15.39% (2/13) in which, only General Mamerto Natividad has shown a positive result.

    Oral and Intramammary Infusion of probiotic against mastitis in water buffalo (Bubalus bubalis)
    (2019) Maynard A. Villamil
    This study determined the efficacy of probiotic against mastitis in water buffalo in oral and intramammary infusion. This was done by comparing the effective route of administration and comparing against antibiotic use. Water buffaloes with clinical mastitis were sourced out from the Philippine Carabao Center national Gene Pool. Clinical mastitis condition was determined using physical evaluation which consisted of palpation of mammary gland and the California Mastitis Test. OptiproR, thr probiotic dosage was 1 gram of directly dissolved in 1 liter of distilled water as a premix in 1 kg of feeds. Probiotics was infused directly into the teat sinus via the streak canal using a sterile blunted syringe needle 10 mL was given per teat per day for 1 month and 100 mL of probiotic was administered to the animal orally per day for 1 month. For the antibiotic the standard treatment of the farm was done, that is, intramammary infusion of the 10 mL (200 mg) of Cephapirin Sodium was given once per teat of the animal. Result showed that probiotic had an effect against mastitis and the most effective route was oral administration of probiotics. Comparably, antibiotic also had an effect on mastitis but it could be costly , traumatic in animals and could cause possible antibiotic resistance.
