Abstract

ABSTRACTHematology studies between Vertebrate classes can provide supporting data related to animal activities and adaptation to their habitat. Low Vertebrate ektoterm showed different hemotological profil than endoderm Vertebrate. The aims of this study is to compare hematological profile between Vertebrate which includes five classes animal taxon. Animal species was taken randomly, considered to represent the five classes taxon: Clarias batracus from Class Pisces, Rana sp. from Class Amphibia, Eutropis multifasciata from Class Reptilia, Columba livia from Class Aves and Mus musculus from Class Mammalia. Hematology parameters were observed was hemoglobins, HCT, erythrocyte count, leukocyte count, leukocyte differential, MCV, MCH and MCHC. The result showed Vertebrate from Class Pisces (catfish), amphibian (frogs) and reptiles (lizards) had hemoglobin, hematocrit, erythrocytes higher than Aves and Mammals. Leucocytes count in Class Pisces, Amphibians, Reptiles and Aves range 12.000-19.000 cells/mL higher than mammal leukocyte 5000 cells/mL. Differential leukocyte in catfish, frogs, lizards, pigeons and mice have the highest percentage of lymphocytes (37-62%). Keywords: catfish, frog, hematology, lizard, mice, pigeon, vertebrate ABSTRAKStudi hematologi hewan kelas Vertebrata dapat memberikan data pendukung terkait aktivitas hewan dan adaptasi terhadap habitatnya. Hewan Vertebrata tingkat rendah yang ektoterm mempunyai profil hematologi yang berbeda dengan Vertebrata tinggi yang sebagian besar endoterm. Tujuan dari penelitian ini adalah untuk membandingkan profil hematologi antar hewan Vertebrata yang meliputi lima kelas hewan takson. Hewan sampel diambil secara acak dari populasi hewan yang mewakili lima kelas takson: Clarias batracus dari kelas Pisces, Rana sp. dari kelas Amfibi, Eutropis multifasciata dari kelas Reptil, Columba livia dari kelas Aves dan Mus musculus dari kelas Mammalia. Parameter hematologi yang diamati adalah hemoglobin, hematokrit, jumlah eritrosit, jumlah leukosit, leukosit diferensial, MCV, MCH dan MCHC. Hasil pengukuran hematologi menunjukkan Vertebrata dari kelas Pisces (lele), Amfibi (katak) dan Reptil (kadal) memiliki hemoglobin, hematokrit, eritrosit lebih tinggi dari pada Aves dan Mamalia. Jumlah leukosit di kelas Pisces, Amfibi, Reptil, dan Aves berkisar 12.000-19.000 sel/mL lebih tinggi dari leukosit mamalia yakni 5000 sel/mL. Pengamatan leukosit diferensial pada ikan lele, katak, kadal, merpati, dan tikus menunjukkan persentase limfosit tertinggi (37-62%) dibanding jenis leukosit lain. Kata kunci: ikan lele, katak, hematologi, kadal, mencit, merpati, vertebrata

Abstract

Mud crabs (Scylla serrata Forskal, 1775) is a species of fishery commodity that can be attacked by pathogenic agents such as ectoparasites. Ectoparasites that infect mud crabs can trigger damage to the carapace and gills at a certain number of infections. This study aims to determine the prevalence and intensity of ectoparasites in mud crabs in Selat Remis Village, Teluk Pakedai District, Kubu Raya Regency. The study was conducted by taking random samples and determining the sample size based on the Lemeshow formula (95% confidence level), then to obtain prevalence and intensity it was carried out by examining the body organs (carapace, cheliped or (pereiopod I), pereiopods (walking legs), pereiopod V (swimming legs) and gills) of mud crabs (S. serrata) and identify the species of ectoparasites. Based on the results, the average prevalence of ectoparasites in mud crabs is 45,00% included in the commonly prevalence category. The prevalence value of each ectoparasites was Vorticella (17,50%), Zoothamnium (12,50%), Octolasmis cor (12,50%), Epistylis (15%), Octolasmis angulata (7,50%) and Acineta (2,50%). The highest intensity value of ectoparasites in mud crabs was O. angulata, 28 individuals per an infected mud crab.

Abstract

West Kalimantan experiences a tropical climate characterized by elevated humidity, which creates an environment conducive to the proliferation of Pityriasis versicolor due to Malassezia furfur. Plants with medicinal properties that include alkaloids, flavonoids, phenols, terpenoids, tannins, and quinones, such as sembung rambat (Mikania micrantha Kunth.), represent promising sources of antifungal compounds. This research sought to assess the antifungal efficacy of the methanol extract from sembung rambat leaves against Malassezia furfur in a laboratory setting and to identify its minimum inhibitory concentration. The disc diffusion technique was employed with extract concentrations of 20%, 25%, 30%, and 35%. Ketoconazole at 2% acted as the positive control, while sterile distilled water was utilized as the negative control. The diameters of the inhibition zones were evaluated using the Kruskal-Wallis test, accompanied by Duncan's multiple range test. The findings indicated that all concentrations of the extract successfully suppressed the growth of Malassezia furfur. The minimum inhibitory concentration was established at 20%, resulting in an inhibition zone measuring 0.48 cm in diameter after 48 hours of incubation. The methanol extract of sembung rambat leaves displayed a fungistatic action against Malassezia furfur in vitro.
