Latar belakang: Pemenuhan kebutuhan pangan asal ternak yang berasal dari unggas memiliki angka konsumsi yang cukup tinggi salah satunya yaitu ayam broiler. Untuk memenuhi tingginya permintaan terhadap ayam broiler pada pakandiberifeed additiveserta antibiotic growth promotor (AGP) dalam bentuk antibiotik untuk mempercepat pertumbuhan dan daya tahan tubuh. Pemanfaatan antibiotik yang tidak bijak akan menimbulkan residu antibiotik serta resistensi Escherichia coli penghasil Extended Spectrum β-lactamase (ESBL).Metode: Penelitian ini termasuk penelitian deskriptif. Data primer diperoleh dari hasil screeningtest. Data ditunjukkan dalam tabel dangambar yang dibahas secara deskriptif. Variabel yang diamati residu antibiotik tetrasiklin serta E. coli penghasil ESBL pada daging ayam broiler.Hasil: Temuan terhadap residu antibiotik tetrasiklin pada daging ayam broiler yaitu sebesar 7,14% dengan rerata zona hambat 12,13 mm, sedangkan hasil identifikasi E. coli penghasil ESBL pada daging ayam broiler diperoleh hasil sebesar 71,4%.Simpulan:Residu antibiotik tetrasiklin dalam daging ayam broiler masih tergolong aman dapat dikonsumsi namun, temuanE. coli penghasil ESBL pada daging ayam broiler menimbulkan masalah kesehatan, baik bagi kesehatan hewan maupun manusia, serta dapat menimbulkan resistensi terhadap antibiotik. ABSTRACT Title: Broiler Chicken Meat Sold at Purwokerto's Market Has Antibiotic Residues and Escherichia Coli That Produces EsblBackground: Poultry, of which broiler chickens are one example, is a food source with a relatively high consumption rate.Feed additives and antibiotic growth promoters (AGP) in the form of antibiotics in the ration are given to increase broilers’ growth and endurance to meet the high demand for them. It is important to note that unwise antibiotic use results in the buildup of antibiotic residues and resistance to the Extended Spectrum Beta-lactamase(ESBL)produced by Escherichia coli bacterium.Method: To collect primary data for this descriptive study, the screening test results were employed as a starting point. Next, the information was presented in the form of tables and figures.Result: According to this study, broiler chickens had a tetracycline residue of 7.14 percent, with an inhibitory zone mean of 12.13 mm, and 71.4 percent of ESBL-producing E. coli.Conclusion:According to the study, broiler chicken meat with tetracycline residue is still safe to consume. E. coli, which is known to develop an antibiotic-resistant strain of E. coli ESBL) can cause serious health problems in both humans and animals.

Background: World Health Organization (WHO) data collection of Escherichia coli resistant to cephalosporin generation III already confirmed in 86 countries. Incredibly high carrier prevalence rates were also widely developed in Thailand, Egypt, and China. The Faculty of Medicine's research team at Jenderal Soedirman University, Purwokerto,  discovered at the beginning of 2018 that Extended Spectrum β-Lactamase (ESBL) E. coli carriers throughout the 2015 class students were 26.8 percent.Objective: This research investigated the Prevalence and associated factors of ESBL-producing Enterobacteriaceae (EPE) asymptomatic carriers in the community.Methods: The participant fill a questionnaire, and samples were taken from rectal swabs using Amies transport medium (Labware Charuzu), and then models were analyze using HiCrome ™ ESBL Agar Base (Himedia, India). Analysis of its Prevalence and Resistance Predictors uses IBM SPSS Statistics Version 22.0 for Windows (Armonk, NY: IBM Corp).Results: The Prevalence of EPE asymptomatic carriers in the community in Purwokerto was 66.7%. In the bivariate analysis, subjects who took antacids in the last eight weeks, history of hospitalization in the previous 12 months, the habit of consuming milk, yogurt, cheese, meat, seafood, and raw vegetables did not show any significant difference. Frequent chicken and freshwater fish consumption tended to be a risk factor for ESBL-producing Enterobacteriaceae with PR 1.462, 95% CI (1.115-1.918); PR 1.666, 95% CI  (0.936-2.966); however, in the multivariate logistic regression analysis, this was not significant.Conclusion: The Prevalence of EPE asymptomatic carriers in the community in Purwokerto is 66.7%. All variables did not become any significant of ESBL-producing Enterobacteriaceae. However, ESBL remains an emerging antimicrobial resistance.

Salmonella typhi adalah bakteri gram negatif penyebab demam tifoid. Penyakit ini dapat dicegah dengan mengonsumsi makanan fermentasi yang mengandung bakteri asam laktat (BAL). Yoghurt merupakan salah satu produk olahan hasil fermentasi BAL dengan bahan dasar susu. BAL yang digunakan dalam pembuatan yoghurt adalah single strain Lactobacillus bulgaricus, Streptococcus thermophilus serta double strain Lactobacillus bulgaricus dan Streptococcus thermophilus. Penelitian ini bertujuan untuk mengetahui perbandingan BAL yoghurt single strain dengan double strain dalam menghambat pertumbuhan Salmonella typhi dengan menghitung rata-rata zona hambat yang terbentuk. Metode penelitian ini adalah experimental design dengan post test only with control group design. Pengujian bakteri menggunakan difusi sumuran. Total sampel sebanyak 16 sampel dibagi menjadi 4 kelompok konsentrasi masing-masing 0%, 20%, 40%, 60%, dan 80%. Rancangan percobaan pada penelitian ini menggunakan metode Rancangan Acak Lengkap (RAL). Analisis data menggunakan uji Kruskal Wallis dan Post Hoc Mann Whitney. Hasil penelitian didapatkan median diameter zona hambat BAL yoghurt double strain Streptococcus thermophilus dan Lactobacillus bulgaricus > single strain Lactobacillus bulgaricus > Streptococcus thermophilus. Pada uji Kruskal Wallis didapatkan nilai p = 0,000, terdapat perbedaan antara kelompok yang diberi perlakuan dan tidak diberi perlakuan. Hasil uji  penelitian didapatkan perbedaan signifikan median diameter zona hambat antar kelompok. Kesimpulan dari penelitian ini menunjukan bahwa yoghurt double strain memiliki kemampuan penghambatan pertumbuhan Salmonellla typhi yang lebih baik dibandingkan yoghurt single strain Lactobacillus Blugaricus atau  Streptococcus thermophilus.
