Abstract

Salmonella gallinarum, the causative agent of fowl typhoid, is a highly pathogenic bacterial disease associated with substantial mortality in poultry, predominantly affecting adult chickens and turkeys. This study aimed to describe the pathological lesions and microbiological characteristics of S. gallinarum infection in chickens with fowl typhoid. S. gallinarum is a gram-negative, rod-shaped, facultative anaerobic bacterium with an optimal growth temperature of 37 °C and the ability to survive across a broad pH range (4.0–9.0). Necropsy findings in affected chickens revealed interstitial pneumonia of the lungs, intestinal hyperemia with petechial hemorrhages, hepatomegaly, splenomegaly, and fatty degeneration of the cardiac tissue. Bacterial culture of intestinal swab samples on MacConkey agar demonstrated the growth of pale-yellow colonies consistent with S. gallinarum. Microscopic examination confirmed Gram-negative bacilli, while biochemical testing showed an alkaline/acid reaction, absence of gas and H₂S production, non-motility, and negative indole and urease reactions

Abstract

Susu sapi merupakan produk utama yang dihasilkan sapi perah. Kandungan susu sapi yang beragam, menjadikan susu sebagai sumber nutrisi yang baik untuk metabolisme tubuh. Tingginya permintaan susu di Indonesia belum terpenuhi karena adanya aspek kesehatan dari sapi yang mengalami mastitis. Staphylococcus aureus adalah salah satu patogen yang menyebabkan mastitis subklinis pada sapi. Tujuan dari penelitian ini adalah untuk mengetahui cemaran Staphylococcus aureus pada sampel susu sapi yang menderita mastitis subklinis di Pangalengan. Penelitian ini dilakukan dengan metode deskriptip kualitatif, menggunakan 48 sampel susu sapi perah mastitis dengan hasil uji CMT . Isolasi dan identifikasi Staphylococcus aureus dilakukan dilakukan melalui metode kultur pada media Blood Agar Plate (BAP), Mannitol Salt Agar (MSA), pewarnaan Gram, uji katalase, uji DNase, serta uji koagulase. Dari 48 sampel terdapat 17 isolat yang mengandung Staphylococcus aureus. 17 isolat menghasilkan hemolisin pada blood agar, memfermentasikan mannitol, pewarnaan Gram positif kokus, katalase positif, koagulase positif dan DNase positif.  Kata kunci : mastitis subklinis; susu sapi; Staphylococcus aureus.

Abstract

The health of beef cattle is a crucial aspect of livestock management. Effective health management in cattle serves to minimize potential economic losses caused by diseases that commonly affect beef cattle. These diseases may be caused by bacteria, fungi, viruses, as well as blood and gastrointestinal parasites. Multiple infections may occur, particularly when suboptimal animal conditions and environmental factors support disease transmission. This case report aims to describe the occurrence of multiple infections and to identify the causative infectious agents in a beef cattle farm located in Cibiru, West Java. The case involved a 4-year-old Limousin cow that exhibited clinical signs including nasal discharge, hypersalivation, diarrhea, and tick infestation. Samples collected for diagnostic examination included nasal discharge swabs, blood, and fecal samples. Nasal swab samples were cultured on blood agar plates (BAP) and MacConkey agar (MCA), followed by primary tests including Gram staining, catalase test, coagulase test, and biochemical tests. Blood samples were examined using blood smear evaluation and differential leukocyte counts. Fecal samples were examined using native smear, flotation, sedimentation, and McMaster techniques. The results revealed a case of multiple infections, with the identification of Staphylococcus aureus and Klebsiella pneumoniae, as well as a gastrointestinal parasitic infection (coccidiosis). In addition, infestation with Rhipicephalus ticks contributed to blood parasitic infections, including babesiosis and anaplasmosis. These concurrent infections were associated with a compromised immune status and reduced production performance, potentially leading to economic losses for the farmer. Therefore, preventive and control measures, including proper sanitation and biosecurity, are essential, as infected animals and contaminated environments may act as sources of disease transmission.

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.
