Abstract

Antimicrobial Resistance (AMR) has become a global health problem. Escherichia coli bacteria in water can act as a reservoir for the spread of antibiotic resistance. The study aimed to determine the resistance of Escherichia coli isolated from well water in chicken farms to antibiotics. The study design was an observational survey conducted from November to December 2022 at five chicken farms in Suranadi Village, Narmada District, West Lombok Regency. Five well water samples used in the study came from five wells in chicken farms located 10 meters from the chicken coop. 250 ml of well water samples were taken, put into sterile bottles, and then taken to the Health Laboratory Testing and Calibration Center of West Nusa Tenggara Province for isolation of Escherichia coli. Escherichia coli was isolated by planting on Eosin Methylene Blue Agar (EMBA) and identified using gram staining and biochemical tests. Antibiotic susceptibility testing of Escherichia coli was conducted using the disc diffusion method using five antibiotics: Gentamicin, Tetracycline, Amoxycillin, Chloramphenicol, and Ciprofloxacin. This study successfully isolated four Escherichia coli from five well water samples. The susceptibility test results showed that 75% of the Escherichia coli isolates were resistant to Amoxycillin, 50% to Ciprofloxacin, and 25% to Chloramphenicol. The Escherichia coli isolates were still sensitive to Gentamicin and Tetracycline.

Abstract

Pyometra is a progressive and life-threatening reproductive system disease in female cats, especially those that are not sterilized. This disease is characterized by the accumulation of pus in the uterus due to a bacterial infection triggered by the influence of the hormone progesterone in the diestrus. This study aims to determine the prevalence and characteristics of pyometra cases in cats in Mataram City and identify risk factors. The research was conducted retrospectively by tracing medical record data from three veterinary clinics in Mataram City (ZZ Pet Care Clinic, Medina Vet Clinic, and drh. Rama & Partners Clinic) during the period June 2024 to May 2025. A total of 339 female cats were examined, and 42 cases of pyometra were found with a prevalence of 12.39%. The most cases were found in the age group of 1.5-2 years (52.38%) and domestic race (57.14%). All cats with the disease have not been sterilized with most having no mating history. These results show that active reproductive age, sterilization status, and local race are the main risk factors for pyometra in Mataram City. Therefore, preventive measures such as ovarihysterectomy and education to animal owners about the importance of reproductive management are needed to significantly reduce the incidence of pyometra.
