Abstract

The enzyme monoamine oxidase-A (MAO-A) is a compound that can break down serotonin. So if the level of monoamine oxidase-A in the blood is high, the level of serotonin in the blood will be low. It is known that the enzyme monoamine oxidase-A affects dog aggression. How exactly is the picture of monoamine oxidase-A in the blood of pet dogs has not been widely revealed. The purpose of this study was to determine the levels of monoamine oxidase-A in Kintamani pet dogs. Kintamani dogs are a native Indonesian dog breed found in Kintamani Village, Bali Province, Indonesia. The study used forty dogs, 15 male dogs and 15 female dogs and 10 lactating dogs. The method used in this study was the observation and cross-sectional sampling method and monoamine oxidase-A levels were determined using the elisa technique. The results showed that the average levels of monoamine oxidase-A in male Kintamani dogs (ng/ml) were 3.54 ± 1.9, females 4.85 ± 1.7 and lactating dogs 3.15 ± 2.23. The conclusion that monoamine oxidase-A level depending sex and lactating. The levels of monoamine oxidase in male dogs are lower than in female and lactating dogs. It is recommended to conduct research on the levels of monoamine oxidase A in Kintamani dogs that behave aggressively.

Abstract

Bacteria are microorganisms that can cause various diseases in humans and animals, as well as play a significant role in food safety concerns. One of the most frequently encountered bacterial genera is Staphylococcus sp., which naturally exists as normal flora on the skin and mucous membranes of the digestive and respiratory systems. However, under certain conditions, these bacteria can become pathogenic and lead to infections. Additionally, Staphylococcus species are often found in food products such as meat and milk, posing potential public health risks. This study aims to identify Staphylococcus sp. species from isolates stored at the Veterinary Public Health Laboratory, Faculty of Veterinary Medicine, Udayana University. The isolates were obtained from the tonsils of healthy Landrace piglets aged 2–3 months, collected from Sangeh, Selat, and Taman Giri in Badung Regency, Bali Province. The research methodology included isolate cultivation, primary identification tests such as Gram staining and the catalase test, followed by biochemical tests, including the coagulase test and mannitol salt agar (MSA) test. The identification results revealed that out of 40 Staphylococcus sp. isolates examined, 22 isolates were identified as Staphylococcus aureus, 10 isolates as Staphylococcus epidermidis, and 8 isolates as Staphylococcus saprophyticus. These findings indicate that Staphylococcus aureus was the predominant species in the tested samples. Due to its pathogenic potential, continuous surveillance of Staphylococcus in animals and animal-derived products is essential to mitigate the risk of transmission to humans. Implementing stringent hygiene and sanitation measures in the handling and processing of animal products is recommended to minimize bacterial contamination.

Abstract

Goats are among the earliest domesticated livestock, playing a significant role in human life, including as a source of protein and as sacrificial animals in religious rituals. The objective of this research is to ascertain erythrocyte count, haemoglobin level, and MCH of sacrificial goats in Musholla Al-Ikhwan Patih Nambi, Denpasar City. The research method employed was observational, with a purposive sampling technique. The sample size was 19 male goats that were slaughtered on Eid al-Adha day and were clinically healthy. The parameters observed included erythrocyte count (RBC), haemoglobin (Hb), and MCH. The instrument used to analyse blood samples is the Veterinary Haematology Analyzer Licare CC 3200Vet. The results indicated an average RBC 11.26x106/uL, haemoglobin 9.63g/dL, and MCH 8.51pg. The study's findings indicate that goats deemed to be in good health and slaughtered during Eid al-Adha at Musholla Al-Ikhwan Patih Nambi Denpasar City exhibited normal haematological parameters.
