Abstract

            Ayam broiler merupakan salah satu komoditas unggas utama dalam memenuhi kebutuhan daging sebagai sumber protein hewani untuk masyarakat. Namun, produktivitasnya dapat terganggu oleh penyakit menular, terutama yang menyerang sistem pernapasan dan sistem pencernaan, seperti kolibasilosis dan koksidiosis. Studi ini bertujuan untuk mengevaluasi temuan patologi anatomi, bakteriologi, dan parasitologi pada kasus pada ayam broiler di Tanjungsari, Sumedang, Jawa Barat, yang menunjukkan gangguan pada sistem pernapasan dan sistem pencernaan. Nekropsi dilakukan terhadap tiga ekor ayam broiler berumur 35 hari yang terdiri atas satu ekor ayam sehat, satu ekor ayam sakit, dan satu ekor ayam mati. Pemeriksaan mencakup observasi lesi secara makroskopis, kultur bakteri dari sampel organ paru-paru, hati dan usus, serta pemeriksaan feses menggunakan metode McMaster. Hasil pemeriksaan Patologi Anatomi menunjukkan adanya akumulasi perkejuan pada hati, hepatomegali dengan foci-foci nekrotik, perikarditis, pneumonia kaseosa, serta airsakulitis. Berdasarkan hasil nekropsi, temuan yang didapat merujuk pada ciri kasus kolibasilosis. Kultur bakteri mengidentifikasi Escherichia coli (E. coli) yang diteguhkan melalui uji biokimia. Hasil pemeriksaan feses menunjukkan adanya ookista Eimeria sp. dengan jumlah rata-rata 5.975 ookista/gram feses pada ayam sakit dan 2.675 ookista/gram feses pada ayam sehat dan keduanya termasuk kategori infeksi ringan. Hasil ini menunjukan adanya infeksi campuran antara E. coli dan Eimeria sp. Kombinasi kedua agen infeksius ini memperburuk kondisi klinis ayam, menyebabkan gangguan sistemik dan berdampak negatif pada produktivitas. Oleh karena itu, pengendalian kedua penyakit secara simultan sangat penting dalam manajemen kesehatan unggas.

Abstract

Pullorum disease or Chalky feces, caused by Salmonella pullorum bacteria, is a highly contagious bacterial infection that significantly affects commercial poultry, particularly in developing countries. This study was aimed to report a case of pullorum disease in commercial layer chickens in Sumedang, West Java, Indonesia. The diagnostic approach included clinical examination based on clinical signs, followed by pathological and microbiological identification. Clinical signs observed were lethargy, white diarrhea (chalky feces) and decreased egg production. Necropsy findings revealed pathological changes including hepatomegaly, splenomegaly, caseous masses in the caecum and joints, oophoritis and white nodules in the heart. Additional anatomy pathological findings included tracheal hyperemia and malacia in the brain. Bacterial isolation and identification were conducted from internal organs using MacConkey Agar, followed by Gram staining and biochemical tests including Kligler’s Iron Agar (KIA), Motility Indole Urea (MIU) and Simmons’s Citrate Agar. The results confirmed the presence of S. pullorum bacteria, characterized by non-motile, Gram-negative bacilli. These findings demonstrate that S. pullorum can cause systemic infection affecting multiple organs. Based on pathological and microbiological examinations, it was concluded that the disease case in the layer chicken samples was caused by chronic infection of S. pullorum. This report highlights the importance of early diagnosis and improved biosecurity measures to prevent outbreaks, reduce mortality rates and minimize economic losses in Chicken farming.
