STRUKTUR ANATOMI DAN HISTOLOGI USUS BESAR GARANGAN JAWA (Herpestes javanicus)

ABSTRAK

Garangan jawa (Herpestes javanicus) merupakan mesokarnivora pemangsa vertebrata kecil, krustasea, gastropoda, serta buah-buahan. Organ pencernaan berperan penting memproses berbagai jenis pakan tersebut, salah satunya adalah usus besar. Penelitian ini bertujuan untuk mengetahui morfologi, morfometri, histomorfologi, dan histomorfometri usus besar garangan jawa. Penelitian ini menggunakan tiga ekor garangan jawa betina dewasa yang berhabitat di Banda Aceh dengan bobot badan 800-1.000 g dan panjang tubuh total 65-75 cm. Morfologi yang diamati meliputi bentuk dan warna, morfometri meliputi berat, volume, panjang total, dan panjang setiap bagian usus besar. Histomorfologi yang diamati meliputi struktur setiap lapisan, histomorfometri mencakup kedalaman kripta dan ketebalan setiap lapisan usus besar. Seluruh data dianalisis secara deskriptif. Data morfologi dan histomorfologi disajikan dalam bentuk gambar. Data morfometri dan histomorfometri disajikan dalam bentuk tabel berupa rata-rata dan standar deviasi. Hasil penelitian menunjukkan bahwa usus besar garangan jawa berbentuk tabung lurus dengan sedikit melengkung pada bagian sekum, berwarna merah muda sampai krem, berat total 5,8±0,08 g, volume total 5,66±1,24 ml, dan panjang total 12,83±1,19 cm. Panjang sekum 2,33±0,28 cm, kolon 4,03±0,68 cm, dan rektum 6,46±0,45 cm. Histomorfologi usus besar terdiri atas empat lapisan, yaitu tunika mukosa, tunika submukosa, tunika muskularis, dan tunika serosa. Rataan kedalaman kripta pada sekum 206,±44,95 μm, kolon 349,72±25,29 μm, dan rektum 287,49±39,23 μm. Semakin ke arah caudal, ketebalan lapisan setiap bagian usus besar cenderung meningkat, kecuali pada tunika submukosa. Kesimpulan penelitian ini adalah morfologi dan morfometri usus besar garangan jawa relatif mirip dengan usus besar garangan abu-abu india, serta secara histomorfologi dan histomorfometri relatif mirip dengan kucing.

ANATOMICAL AND HISTOLOGICAL STRUCTURE OF THE LARGE INTESTINE IN THE JAVAN MONGOOSE (Herpestes javanicus) ABSTRACT Javanese mongoose (Herpestes javanicus) is mesocarnivorous preys on small vertebrates, crustaceans, gastropods, and fruits. Digestive system responsible for processing this various type of food, one of which is large instestine. This study aimed to understand the morphology, morphometry, histomorphology, and histomorphometry of large intestine of Javanese mongoose. This study used three adult female Javanese mongooses inhabiting Banda Aceh with body weights of 800-1.000 g and total body length 65-75 cm. Morphological observations included shape and color, morphometric included weight, volume, total length, and length each segment of large intestine. Histomorphological observations included structure each segment, histomorphometric included crypt depth and thickness each layer of large intestine. All data were analyzed descriptively. Morphological and histomorphological findings were presented as images. Morphometric and histomorphometric data were summarized in tables as means and standard deviations. Result showed that Javanese mongoose’s large intestine formed straight tube with slight curve at cecum, colored pink to cream, total weight 5.8±0.08 g, total volume 5.66±1.24 ml, and total length12.83±1.19 cm. The length of large intestine parts including caecum 2.33±0.28 cm, colon 4.03±0.68 cm, dan rectum 6.46±0.45 cm. Histologically, large intestine consists of four layers, including tunica mucosa, tunica submucosa, tunica muscularis, and tunica serosa. Crypt depth in caecum 206.18±44.95 μm, colon 349.72±25.29 μm, and rectum 287.49±39.23 μm. Toward the caudal end, all layers of large intestine increased in thickness except the submucosa. The conclusion is morphology and morphometry of large intestine of Javanese mongoose relatively similar to Indian gray mongoose, histomorphologically and histomorphometrically relatively similar to cats.
