“…S. aureus is a main cause of mastitis in cows. One of the utilization reasons of antibiotics in cows is for treatment of this disease, which might result in antibiotic resistance (22). Our recent reports had indicated that although S. aureus had not had any resistance to ciprofloxacin and gentamicin, it showed the highest resistance to penicillin and oxacillin.…”

Background: Foodborne diseases are one of the most major public health concerns in the world. Ice cream flavors, especially the traditional ones, have a high potential for the transmission of the pathogenic bacteria. Objectives:The aim of the current study is to investigate the microbiological status and antibiotic resistance of Escherichia coli and Staphylococcus aureus isolated from traditional ice cream. Methods: A total of 114 traditional ice creams were randomly collected from retail stores in Hamadan, Iran. Samples were investigated for the total bacteria count (TBC) and contamination with the coliform, Enterobacteriaceae and Salmonella as well as the prevalence and antibiotic resistance of Staphylococcus aureus and Escherichia coli. Results: The count of Enterobacteriaceae (89.47%), mold and yeast (50%), coliform (40.35%) and TBC (28.07%) of samples was higher than Iran's standard. Salmonella was not found in all samples. The prevalence of Staphylococcus aureus and Escherichia coli was confirmed in 50% and 37.72% of samples, respectively. Collected Escherichia coli had the highest antibiotic resistance to ampicillin 67.44%, nalidixic acid 39.53% and co-amoxyclav 37.21%. Staphylococcus aureus showed a higher antibiotic resistance to penicillin (82.46% of isolates) and oxacillin (38% of isolates). Conclusions:The results showed high contamination levels of traditional ice cream with spoilage and pathogenic microorganisms as well as considerable resistance of isolated Staphylococcus aureus and Escherichia coli to common antibiotics. Therefore, good hygienic practice during processing and personal hygiene should be considered to improve the quality of ice cream. In addition, it is necessary that the regulatory authorities carry out more control on the production centers of traditional ice cream.

“…Several studies have been done in relation to antibiotic resistance patterns in traditional ice cream, raw milk and other dairy products all around the world (6,(20)(21)(22)(23)(24) . In other surveys, more TBC (51 to 78.8%) than the current study has been reported (25)(26)(27).…”

Mastitis, a disease complex of multiple etiologies, results into considerable financial losses to dairy industry worldwide. A cross sectional study was carried out between July 2013 to August 2013 in Asella town and its surrounding areas in order to cefotaxime, penicillin G, amoxicillin, ampicillin and vancomycin, which accounted 97.9%, 96.4%, 80.4%, 80.2% and 78%, respectively. Staphylococcus aureus revealed resistance against penicillin G, amoxacillin and tetracycline, which accounted 97.9%, 96.4% and 80.4%, respectively and Escherichia coli showed resistance against vancomycin, ampicillin and penicillin G, which indicated 83%, 74% and 65%, respectively

Presence of Staphylococcus aureus in goat milk and dairy product could lead to human illness. The aim of the present study was to characterize S. aureus isolated from goat milk and its products. The samples used in these studies ABSTRAKKeberadaan Staphylococcus aureus pada susu kambing dan produk olahannya dapat menyebabkan penyakit pada manusia. Tujuan penelitian ini untuk isolasi dan karakterisasi S. aureus dari susu kambing dan produk olahannya. Susu kambing dan produk olahannya yang digunakan dalam penelitian ini d iambil dari peternakan kambing dan tempat pengolahan susu kambing di kabupaten Sleman. Isolasi S. aureus berdasarkan reaksi biokimia. Karakterisasi S. aureus dilakukan terhadap hemolisin, klumping faktor, koagulase, dan sensitifitas antibiotik. Hemolisin d itentukan dengan kulture pada b lood agar plate, sedangkan klumping faktor dengan slide agglutination test. Mencampur plasma kelinci dengan kulture cair S. aureus dalam tabung reaksi digunakan untuk deteksi koagulase, sedangkan sensitifitas antibiotik dengan agar difusi. Hasil analisis menunjukkan bahwa susu kambing dengan jumlah S. aureus yang masih memenuhi ketetapan SNI No 01-6366-2000 sebanyak 86%. S. aureus dari susu kambing memiliki karakter tidak hemolitik 80%, klumping faktor positif 20%, koagulase positif 40%, resisten terhadap ampisilin dan penisilin 30%, sedangkan terhadap eritromisin, neomisin, sulfonamide, dan tetrasiklin masing-masing 10%.
