Dermatophytosis is one of the superficial mycoses which causes skin health problems in pet animals. This study conducted molecular characterization using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) on specimens obtained from patients suspected of dermatophytosis in several clinics in DKI Jakarta Province and Bogor City. Fifty samples of skin scrapings from patients suspected of clinically dermatophytosis were collected and analyzed by conventional and molecular techniques. The Research aimed to identify dermatophyte that were isolated from pet animals using PCR-RFLP technique. The primers of ITS 1, ITS 4, Chytin Synthase, and cutting enzymes of Dde1 were used in this Research. Four specimens off 50 spesimens were tested positive using direct and culture PCR examination techniques. Based on the sequencing results, Microsporum canis was identified in four spesimens. Specimens that were positive for dermatophytes followed by RFLP using the Dde 1 enzyme. The results of the study showed that molecular techniques were a reliable way to determine the high-precision dermatophytes in diagnosing dermatophytosis. The Results also showed that molecular arrangement of B1 isolate was different from three other isolates.

Chicken is one of the important protein source in Indonesia. Moreover, the largest population of chicken layer and poultry in Indonesia is known situated at West Java province with Bogor manicipality as the main producer. The aims of this study were to determine the antibiotic resistance pattern of Staphylococcus aureus isolated from poultry and layer farm in Bogor. The study also identified gene encoded the resistance. Cloacal swab samples were collected from chicken broiler and layer farm in Bogor manicipality. The samples were then cultured in Mannitol Salt Agar (MSA) medium to obtain S. aureus. Suspected colony was then confirmed by biochemical test. Positive strains were tested against several antibiotics and the diameter of clear zone arround of colony was interpreted based on Clinical and Laboratory Standard Institute. Furthermore, the DNA from resistant strains were then extracted, followed by detection of the resistance gene by using polymerase chain reaction (PCR) method. A total of 14 isolates of S. aureus were positive from poultry farm, and 15 isolates from layer farm. Most of all were resistant to tetracycline, ampicillin, oxytetracycline, erythromycin and nalidixic acid. On the other hands, several strains were sensitive to gentamycin and chloramphenicol. The study showed 28 isolates out of them were multi-drug resistant. Resistant gene such as blaTEM, gyrA and tetA were also identified in some isolates except for ErmB gene which was found in isolates originated from poultry farm. In conclussion, S. aureus in both farm showed mostly multi-drug resistant to several antibiotics which were supported by identification of resistant gene among isolates.

Dangke is a traditional food in Enrekang, a district in South Sulawesi. Its made from buffalo’s milk orcow’s milk. Dangke could be contaminated during the process with Escherichia coli which causes diarrheain children and adults. It was known that supernatant of Lactobacillus plantarum has antibacterial capacity,and it may be used as a biopreservative agent. The research aims were to determine the minimum inhibitoryconcentration (MIC) of L. plantarum supernatant in inhibiting the growth of E. coli ATCC 25922, determinethe nutrients level of cow’s milk dangke after the addition of 1% and 2% milk fat, as well as determine theeffect of L. plantarum supernatant and cow’s milk fat addition into dangke inhibited the growths of pathogenicbacteria of E. coli ATCC 25922. MIC value was determined based on the value of the lowest concentrationof supernatant that shown with no any bacteria growth in the media. Data of pathogenic bacteria growth analyzed with analysis of variance test with a 2x2 factorial design, which 1st factor was the addition of L.plantarum supernatant (with or without addition of supernatant) and the second factor was the additionof fat content (1% and 2%) and time observation was made on days 0, 2nd, 4th, 6th, and 8th. Resultsshowed that the filtrate of fermented L. plantarum was able to inhibit the growth of E. coli ATCC 25922in vitro and had 10% minimum inhibitory concentration (MIC). Level of fat and protein in dangke whichadded 1% cow’s milk fat, was higher than with 2% cow’s milk fat. The L. plantarum supernatant is provedto be able to inhibit the growth of E. coli ATCC 25922. Therefore, it is potentially used as a naturalbiopreservative agent in making dangke.

Antibiotic resistance has become a global problem that can threaten human and animal health. The use of antibiotics in livestock as a treatment and control of disease is often associated with the cause of the spread of resistant bacteria. Resistance bacteria are caused by presence of resistant gene resistance that can move between bacteria. This study aims to detect the presence of genes that encode resistance to ampicillin (ampC) antibiotics and colistin (mcr-1) in Escherichia coli bacteria derived from cases of colibacillosis in Sukabumi. A total of 25 isolates of E. coli archive collection of PT. Medika Animal Lab is used in this research. All isolates identified using PCR were then tested for sensitivity using the disk diffusion method and minimum inhibitory concentrations (MICs). Isolates that are resistant to ampicillin and colistin were tested for detection of ampC and mcr-1 genes using PCR. The results of the sensitivity test showed the whole isolates were resistant to ampicillin (100%) and phosphomycin (8%), but none were resistant to colistin sulphate. The total isolate E. coli successfully detected gene encoding resistance of ampC (100%). The results of sensitivity and resistance detection test showed that the whole isolates were ampicillin resistant and had the ampC resistance-encoding gene.

Resistansi antimikrob merupakan masalah kesehatan global. Antimikrob termasuk antibiotik digunakan untuk mengobati infeksi pada manusia dan hewan. Penyalahgunaan antibiotik dapat menyebabkan resistansi dan pengobatan menjadi tidak efektif. Penelitian ini bertujuan untuk mengisolasi Escherichia coli (E. coli) dari hewan, manusia dan lingkungan di peternakan babi di Kabupaten Badung Provinsi Bali, serta menentukan pola resistansi dan gen resistansi antibiotik. Sampel diambil dari 12 peternakan babi yang berdekatan dengan total 24 sampel feses babi, 24 sampel swab tangan pekerja kandang, dan 12 sampel limbah air. Escherichia coli diisolasi menggunakan MacConkey Agar, pewarnaan Gram, IMViC (Indole, Methyl Red, Voges Proskauer, Citrate) dan dikonfirmasi dengan Polymerase Chain Reaction (PCR). Uji kerentanan terhadap 11 antibiotik menggunakan metode difusi cakram. Deteksi gen resistansi antibiotik dengan PCR untuk gen blaTEM, ampC, ermB, strA, tetA, dan sul1. Hasil menunjukkan 100% (24/24) E. coli diisolasi dari feses, 16,7% (4/24) dari swab, dan 100% (12/12) dari limbah air. Pola resistansi antibiotik menunjukkan bahwa resistansi tertinggi terhadap eritromisin, diikuti oleh amoksisilin dan ampisilin, tetrasiklin, streptomisin dan trimetropim-sulfmetokzasol, serta 14 isolat dikategorikan Multidrug Resistant (MDR). Gen resistansi yang dideteksi dari E. coli pada manusia, hewan dan lingkungan adalah blaTEM, ampC, strA, tetA dan sul1, sementara ermB tidak terdeteksi. Berdasarkan hasil penelitian, pemberian antibiotik eritromisin, amoksisilin, ampisilin, tetrasiklin, streptomisin dan trimetropim-sulfmetokzasol sebaiknya diganti dengan antibiotik jenis lain. Adanya gen resistansi yang berasal dari sampel feses babi, swab tangan dan limbah air mengindikasikan terjadinya penyebaran resistansi antibiotik pada manusia, hewan dan lingkungan.
