Background: Methicillin-Resistant Staphylococcus aureus (MRSA) is a big challenge for health services worldwide which causes infections both in healthcare and community. Healthcare-associated MRSA (HA-MRSA) strains are shown to be resistant to beta-lactam antibiotics and several non-beta lactam antibiotics. At the same time, the community-associated MRSA (CA-MRSA) tends to be resistant to beta-lactam antibiotics. MRSA carried staphylococcal cassette chromosome (SCCmec) types I, II, III, IV, and V. SCCmec types I, II, and III were predominantly found in HA-MRSA strain while SCCmec types IV and V predominantly found in CA-MRSA strains. Furthermore, the panton valentine leukocidine (pvl) gene is commonly found in CA-MRSA strains. Therefore, this study aimed to determine the prevalence of SCCmec types I, II, III, and pvl gene in MRSA isolated from clinical specimens in Sanglah General Hospital. Methods: This study was a cross-sectional descriptive study. MRSA was isolated from clinical specimens (sputum, wounds, tissue, blood, etc.) from January 2020 to July 2021 and identified by the Vitek 2 Compact (Biomerieux, France) at the Clinical Microbiology Laboratory of Sanglah Hospital. Prevalence of SCCmec and pvl gene using PCR. Data were analyzed using Microsoft Excel version 2010 for Windows. Results: Most of the specimens (69.56%) were wound. Seventeen (73.91%) out of 23 MRSA isolates were positive for the SCCmec III and pvl gene, while none was positive for the SCCmec I and SCCmec II. About 19 (82.60%) isolates were resistant to two or more non-beta-lactam antibiotics. Conclusions: The isolates of MRSA in this study were predominantly isolated from wound specimens, with the most prevalent genetic element being SCCmec III. In this study, although most MRSA isolates carried SCCmec III that suggested as HA-MRSA, however, most of the strains harbored the pvl gene. This interesting phenomenon needs to be further elucidated.

Background: Waterborne diseases spread through drinking water and food products made from drinking water, including cooking utensils that are washed using contaminated water. Ice cube is widely used by the people in Indonesia. There was no study regarding bacteria contamination on an ice cube in Karangasem Regency. This study aimed to determine the contamination of Escherichia coli, Salmonella sp., and Vibrio sp. on ice cubes at food stalls in Karangasem Regency in 2021. Methods: This study used a cross-sectional research design and simple purposive sampling as the sampling technique. Ice cubes were taken from 42 food stalls from eight sub-districts. Samples were cultured on Lactose Broth (LB) media for the Most Probable Number (MPN) test procedures and Eosin Methylene Blue Agar (EMBA) to identify the presence of E. coli, Salmonella Shigella Agar (SSA) for Salmonella sp., and Thiosulfate Citrate Bile Sucrose (TCBS) for Vibrio sp. and followed by gram staining. Data processing was carried out descriptively to determine the percentage of samples with positive contamination. Data were analyzed using Microsoft Excel version 2010 for Windows. Results: Based on the study results, it was found that all samples contained coliform bacteria through the MPN test (100.0%). In addition, 5 samples (11.9%) were found positive for E. coli. While the identification of Salmonella sp. and Vibrio sp was found no positive results. Conclusions: There was coliform bacteria contamination in the tested ice cube samples. In addition, E. coli was found in the sample; however, there were no Salmonella sp. and Vibrio sp. on ice cube samples.

Background: Food contamination is a serious problem. Salmonella sp is one of the main bacteria causing gastrointestinal disease, especially in raw pork, due to the production and distribution process. Traditional markets have high risk of pathogenic microbial contamination. The purpose of this study was to detect contamination of Salmonella sp. on pork sold in traditional markets, particularly in Denpasar, Bali. Method: This research is a cross-sectional descriptive, with the samples coming from the porks sold by traditional market traders in every sub-district in Denpasar, Bali. The sampling technique used is the cluster purposive sampling. The procedure for identification of Salmonella sp. using culture and subculture examination on Salmonella Shigella Agar (SSA), simmon citrate agar media, and identification of the microscope. Results: Based on SSA culture results from 38 samples, 26 samples of pork showed colony growth, but only 10 samples with typical morphology of Salmonella sp. The 16 samples with atypical morphology were examined for SSA subculture, with 9 samples having clear black colonies. In 19 research samples that showed the results were suspected to be contaminated with Salmonella sp. continued to the Simmons citrate test, but only 8 samples were positive. The 19 samples were also examined under a microscope and all samples showed a rod image and red color indicating that the colonies in the sample were gram-negative bacilli which are typical of the morphology of Salmonella sp. Conclusion: Contamination of Salmonella was found in pork sold at Traditional Markets in Denpasar with a prevalence of 21%. Latar belakang: Kontaminasi makanan merupakan suatu masalah serius. Salmonella sp merupakan salah satu bakteri penyebab utama penyakit gastrointestinal, terutama pada daging babi mentah, dikarenakan pada proses produksi dan distribusi. Pasar tradisional merupakan tempat yang sangat rawan dan beresiko cukup tinggi terhadap cemaran mikroba patogen. Tujuan penelitian ini adalah mendeteksi ada tidaknya cemaran bakteri Salmonella sp. pada daging babi yang dijual di Pasar Tradisional, khususnya di Denpasar, Bali. Metode: Penelitian ini merupakan deskriptif potong lintang, dengan sampel penelitian berupa daging babi yang dijual oleh pedagang pasar tradisional di setiap kecamatan di Kota Denpasar, Bali. Teknik penentuan sampel yang digunakan yaitu teknik cluster purposive sampling. Prosedur identifikasi kontaminasi Salmonella sp. menggunakan pemeriksaan kultur serta subkultur pada Salmonella Shigella Agar (SSA), Kultur pada media simmon citrate agar, dan identifikasi mikroskop. Hasil: Berdasarkan hasil kultur SSA dari 38 sampel daging babi, 26 sampel daging babi menunjukan adanya pertumbuhan koloni, namun hanya 10 sampel dengan morfologi khas Salmonella sp. Pada 16 sampel dengan morfologi tidak khas dilakukan pemeriksaan subkultur SSA, dengan 9 sampel memiliki warna koloni hitam bening. Pada 19 sampel penelitian yang menunjukan hasil terduga terkontaminasi Salmonella sp. dilanjutkan ke uji Simmons citrate, namun hanya 8 sampel dengan hasil positif. Pada 19 sampel juga dilakukan pemeriksaan mikroskop dan seluruh sampel menunjukkan gambaran batang serta berwarna merah yang menandakan bahwa koloni pada sampel adalah basil gram negatif yang khas pada morfologi bakteri Salmonella sp. Kesimpulan: Terdapat cemaran patogen Salmonella sp. pada daging babi yang dijual di Pasar Tradisional di Denpasar dengan prevalensi sebesar 21%.
