      Abstract
      Sapi potong menjadi salah satu komoditas andalan di Provinsi Sulawesi Selatan. Tingginya populasi sapi di Provinsi Sulawesi Selatan diikuti peningkatan konsumsi daging sapi di wilayah tersebut. Populasi sapi dan permintaan pasar akan daging sapi yang tinggi akan meningkatkan aktivitas pemotongan hewan. Aktivitas pemotongan hewan terutama dilakukan pada rumah potong hewan (RPH) dan tempat pemotongan hewan (TPH). Proses pemotongan hewan di RPH maupun TPH akan menghasilkan limbah yang dapat menjadi sumber penularan berbagai penyakit ke lingkungan, salah satunya penyakit Q fever. Mengingat kejadian Q fever di Provinsi Sulawesi Selatan belum pernah dilaporkan sebelumnya, eksplorasi terhadap penyakit ini penting dan perlu dilakukan. Penelitian ini bertujuan untuk mengidentifikasi dan mendeteksi distribusi antigen C. burnetii pada beberapa organ sapi di Provinsi Sulawesi Selatan. Penelitian ini merupakan penelitian eksploratif dan pengambilan sampelnya dilakukan di RPH dan TPH di Kab. Sidenreng Rappang, Kab. Maros, Kab. Bone, dan Kota Makassar, Provinsi Sulawesi Selatan. Pengujian nested-PCR dilakukan untuk mendeteksi agen pada sampel yang dikoleksi dari lapangan. Pada penelitian ini digunakan pasangan primer OMP1-OMP2 dan OMP3-OMP4 yang dirancang untuk mengamplifikasi fragmen masing-masing pada 501 bp dan 437 bp dengan target gen com1. Pewarnaan khusus imunohistokimia (IHK) dilakukan untuk melihat distribusi antigen C. burnetii pada organ-organ dari individu yang terdeteksi positif Q fever. Pewarnaan hematoksilin eosin (HE) dilakukan untuk melihat perubahan histopatologi pada jaringan dari sampel organ dengan hasil positif nested-PCR. Data hasil pengujian nested-PCR disajikan dalam bentuk gambar hasil elektroforesis dan dijelaskan secara deskriptif. Data yang diperoleh dari hasil pewarnaan IHK dan HE disajikan dalam bentuk tabel dan gambar, lalu dianalisis secara deskriptif. Sampel diperoleh dari 100 ekor sapi dari empat kabupaten/kota di Provinsi Sulawesi Selatan. Uji first PCR tidak menunjukkan hasil positif pada seluruh sampel, namun analisis dengan nested-PCR ditemukan hasil positif dengan ukuran pita DNA pada posisi 437 bp yang sesuai dengan kontrol positif. Hasil positif ditemukan pada 3 sampel yang tersebar pada organ berbeda yaitu paru-paru, ginjal, dan hati. Organ tersebut berasal dari 3 ekor sapi berbeda yang merupakan sapi Bali yang dipotong di RPH Tibojong Kab. Bone. Hasil pewarnaan IHK sampel organ menunjukkan imunoreaksi positif terhadap antibodi poliklonal Rabbit anti-C. burnetii FKH IPB pada sampel hati dan ginjal. Hasil pewarnaan HE pada sampel positif tidak menunjukkan lesio spesifik. Ditemukan infiltrasi sel radang derajat ringan pada hati, ginjal, dan paru-paru sebagai respon adanya peradangan pada organ tersebut. Data ini merupakan yang pertama kali dilaporkan dari pulau Sulawesi, khususnya Sulawesi Selatan.
       
      Beef cattle is one of the main commodity of South Sulawesi. The high population followed by high consumption of meat. This big cattle population with increasing market demand for beef, result in high slaughter activities. Slaughter activities primarily take place at slaughterhouses (RPH) and slaughtering facilities (TPH). The slaughter process (both in RPH and TPH) generates waste that could be the source of various diseases for the environment, including Q fever. The incidence of Q fever in South Sulawesi has never been previously reported, thus the exploration of this disease is crucial and necessary. This study aims to identify and detect the distribution of C. burnetii antigens in beef cattle organs in South Sulawesi. The sample of this explorative study was collected from slaughterhouses and slaughtering facilities in Sidenreng Rappang Regency, Maros Regency, Bone Regency, and Makassar City, South Sulawesi. Nested-PCR was performed to detect the Coxiella burnetii in samples. This study performed using two primer pairs, consist of OMP1-OMP2 and OMP3-OMP4. This primers designed to amplify fragments of 501 bp and 437 bp, respectively, targeting the com1 gene. IHC staining was performed to examine the distribution of C. burnetii antigens in organs from individuals with positive Q fever. HE staining was performed to identify the histopathological changes in tissue samples from organs with positive Q fever. Nested-PCR results were presented as electrophoresis images and are described descriptively. Data obtained from IHC and HE staining results are presented in tables and figures, then analyzed descriptively. Samples were obtained from 100 cattle from four districts in South Sulawesi Province. The first PCR test did not show positive results in all samples. However, nested-PCR analysis found positive results with a DNA band at position 437 bp, consistent with the positive control. Positive results were found in three samples consist of lungs, kidneys, and liver. These organs were collected from three different Bali cattle, slaughtered at the Tibojong slaughterhouse in Bone Regency. IHC staining results showed positive immunoreactivity to the Rabbit anti-C. burnetii polyclonal antibody FKH IPB. HE staining results for positive samples did not show any specific lesions. Mild inflammatory cell infiltration was found in the liver, kidneys, and lungs as the response to inflammation in these organs. This data is the first to be reported from Sulawesi, particularly South Sulawesi.
