Abstract

This study aimed to evaluate the effectivity of microencapsulated synbiotic (MS), Bacillus sp. NP5 and mannan oligosaccharide (MOS) dietary in different feeding frequencies in Pacific white shrimp culture field experiment. The MS was administered as a feed supplementation to enhance the immunity for prevention against co-infection with WSSV (White Spot Syndrome Virus) and Vibrio harveyi. The synbiotic was microencapsulated by the spray dryer method. Shrimps were reared in the floating net cages in the pond. Treatments included the administration of MS at different frequencies i.e, daily (A), twice a week (B), once a week (C), and without MS supplementation (consisted of negative and positive controls) with a feeding rate of 6% of shrimp biomass (5 times a day). During the challenge trial, shrimps were removed and further reared in plastic tanks, for 7 days. The shrimps (except negative control treatment) were intramuscularly injected by WSSV filtrate at the infective dosage of 10-4 copies.ml-1. Twenty four hours after WSSV injection the shrimps were immersed in the water-containing cells suspension of V. harveyi at the cell’s population dosage of 106 CFU.ml-1. Immune responses were observed for 7 days after experimental infection. The shrimps that have been treated with daily MS supplementation (A) showed better immune responses i.e., total haemocyte counts, phenoloxidase, respiratory burst, and the lower pathogenic cells abundance in the intestine compared to other treatments groups.

Abstract

ABSTRACT This study aimed to conduct the characterization and molecular detection of the pathogenicity and antibiotic-resistance genes in Vibrio parahaemolyticus, as the causative agent of vibriosis in Pacific white shrimp. The V. parahaemolyticus isolates were collected from the shrimp’s hepatopancreas, before biochemical test and polymerase chain reaction (PCR) sequencing of the 16S rRNA gene confirmation. The hemolysis test and PCR were applied to detect the presence of virulence genes, namely toxR, thermostable direct haemolysin (tdh), and tdh-related haemolysin (trh). The Kirby-Bauer method was used for characterizing the resistance patterns against ampicillin (AMP), tetracycline (TET), cyprofloxacin (CIP), enrofloxacin (ENR), and chloramphenicol (CHL). The biochemical tests and PCR-16SrRNA gene sequencing confirmed that 12 isolates belonged to V. parahaemolyticus that were further verified by amplification of the toxR gene in 382 bp (100% of the isolates). The alpha hemolysis activity was also confirmed by the amplicon of 199 bp in all isolates. All V. parahaemolyticus isolates showed their resistance to AMP and 42% of the isolates were TET-resistant. However, no resistance was shown to CIP, ENR, and CHL. The PCR-based analysis resulted a detectable resistance gene of ampC (42% of the isolates) and tetB (83% of the isolates).

Isolat V. parahaemolyticus dikoleksi dari hepatopankreas, diuji secara biokimiawi dan selanjutnya dikonfirmasi dengan polymerase chain reaction (PCR)-sekuensing dari gen 16S rRNA. Tes hemolisis dan metode PCR diterapkan untuk mendeteksi keberadaan gen virulensi toxR, thermostable direct haemolysin (tdh) and tdh-related haemolysin (trh). Metode Kirby Bauer digunakan untuk karakterisasi pola resistansi terhadap ampisilin (AMP), tetrasiklin (TET), kloramfenikol (CHL), siprofloksasin (CIP) dan enrofloksasin (ENR). Uji biokimia dan sekuensing gen PCR-16SrRNA memastikan bahwa 12 isolat adalah V. parahaemolyticus yang selanjutnya diverifikasi dengan amplifikasi gen toxR berukuran 382 bp (100% isolat). Aktivitas alfa hemolisis juga dikonfirmasi dengan amplikon PCR (199 bp) di semua isolat. Seluruh isolat V. parahaemolyticus menunjukkan resistansinya terhadap AMP, 42% resistan TET, tidak ada resistansi yang ditunjukkan pada CIP, ENR dan CHL. Analisis berbasis PCR menghasilkan gen resistan yang terdeteksi dari gen ampC (42% isolat) dan gen tetB (83% isolat). Kata kunci: Antibiotik, udang, resistansi, virulensi, Vibrio parahaemolyticus

Abstract

The ability to track the presence of pathogenic Vibrio parahaemolyticus, an AHPND causative agent in shrimp is one of the keys to controlling this infectious disease. A reputable disease diagnosis is appreciated as the ability to track the pathogenic infection when the host abnormality is undetectable due to the low pathogenic cell concentration. This mini-review article discusses the selected virulence encoding genes as molecular markers and the steps of standard validation methods in the application for early detection of AHPND disease. The proper diagnosis method is crucial to prevent the spread of Vibriosis AHPND which significantly results in economic losses for shrimp farmers. In this early warning system, we need a molecular method available for quick detection by applying the tracking tools that can discriminate pathogenic V. parahaemolyticus AHPND strain. Several types of potential genes that can be developed into tracking devices for infectious Vibriosis are pathogenic genes encoding the virulence factor. Through several stages of testing the selected virulence encoding genes will be developed into molecular markers. The polymerase chain reaction method and several of its variants have been widely applied using selected molecular markers. Furthermore, the use of molecular markers for the diagnosis of AHPND disease in shrimp must be validated by determining aspects of sensitivity, detection specificity, repeatability consistency, and reproducibility Keywords: virulence-encoding gene, Vibrio parahaemolyticus, AHPND, diagnose, molecular marker ABSTRAK Kemampuan melacak keberadaan patogen Vibrio parahaemolyticus, agen penyebab AHPND pada udang adalah salah satu kunci untuk mengendalikan penyakit menular ini. Diagnosis penyakit yang memiliki reputasi baik akan dihargai karena mampu untuk melacak infeksi patogen ketika tanda-tanda abnormalitas pada inang belum terdeteksi karena konsentrasi sel patogen yang masih rendah. Makalah mini-review ini membahas tentang tahap-tahap metode validasi standardalam aplikasi gen penyandi virulensi terseleksi untuk deteksi dini penyakit AHPND. Metode diagnosis yang tepat sangat penting untuk mencegah penyebaran Vibriosis AHPND yang secara signifikan mengakibatkan kerugian ekonomi bagi petambak udang. Dalam sistem peringatan dini ini, diperlukan metode molekular yang tersedia untuk deteksi cepat dengan menerapkan alat pelacak yang mampu membedakan patogen V. parahaemolyticus strain AHPND. Beberapa jenis gen potensial yang dapat dikembangkan menjadi alat pelacak penyakit Vibriosis menular adalah gen patogen yang mengkodekan faktor virulensi. Beberapa tahapan pengujian harus dilakukan untuk menjadikan gen penyandi virulensi terpilih sebagai kandidat yang akan dikembangkan menjadi penanda molekular. Metode polymerase chain reaction dan beberapa variannya telah banyak diterapkan dengan menggunakan penanda molekular terseleksi. Selanjutnya pemanfaatan penanda molekular untuk diagnosis penyakit AHPND pada udang harus dilakukan validasi dengan menentukan aspek sensitivitas, spesifisitas deteksi, konsistensi pengulangan, dan reprodusibilitas Kata Kunci: gen penyandi virulensi, Vibrio parahaemolyticus, AHPND, diagnosis, penanda molekuler

Abstract

Aeromonas hydrophila is the main causative agent of ulcerative disease in catfish and causes considerable economic losses to Indonesian aquaculture. This study evaluates the prebiotic activity and the effect of feed supplementation of dayak onion simplicia powder (DOSP) on the immune response and survival of catfish infected with A. hydrophila. Five doses (0.20, 0.25, 0.30, 0.35, and 0.40 g/mL) of DOSP were tested in vitro to assess the prebiotic activity score. The results showed that a dose of 0.20 g/mL gave a significantly (P<0.05) higher probiotic stimulation value than other doses. In the in vivo test, the study used a completely randomized design with five treatments, namely simplicia (DOSP 20 g/kg), probiotic (PRO, Bacillus sp. NP5 108 CFU/mL, 1% v/w), combination (PRO+DOSP), and control (positive and negative). Fish were reared for 45 days and fed three times a day. On day 46, fish from all treatments, except negative control, were infected with an A. hydrophila dose of 106 CFU/mL injected intramuscularly. The results showed that the combination treatment (PRO+DOSP) gave better total erythrocytes, hemoglobin, hematocrit, total leukocytes and phagocytosis activity than probiotics, DOSP, and control. Administering the combination (PRO+DOSP) can reduce the total number of A. hydrophila lower than the probiotic, DOSP, and control treatments. In addition, the survival rate of catfish in the combined treatment (PRO+DOSP) was significantly (P<0.05) higher than probiotics, DOSP, and control. The results of this study can be a helpful reference and application for the early prevention of A. hydrophila infection. Keywords: aquaculture, Bacillus sp. NP5, dayak onion, probiotics, simplicia powder ABSTRAK Aeromonas hydrophila adalah penyebab utama penyakit bercak merah pada budidaya ikan lele dan menyebabkan kerugian ekonomi cukup besar pada akuakultur Indonesia. Penelitian ini bertujuan untuk mengevaluasi aktivitas prebiotik serbuk simplisia bawang dayak (SSBD) dan pengaruh penambahan kombinasi probiotik Bacillus sp. NP5 dan SSBD pada pakan terhadap respons imun dan kelangsungan hidup ikan lele yang diinfeksi A. hydrophila. Lima dosis (0,20, 0,25, 0,30, 0,35, dan 0,40 g/mL) SSBD diuji secara in vitro untuk menilai skor aktivitas prebiotik. Hasil penelitian menunjukkan bahwa dosis 0,20 g/mL memberikan nilai stimulasi probiotik signifikan (P<0,05) lebih tinggi dibandingkan dosis lainnya. Pada uji in vivo, penelitian menggunakan rancangan acak lengkap terdiri dari lima perlakuan, yaitu simplisia (SSBD, serbuk simplisia bawang dayak 20 g/kg), probiotik (PRO, Bacillus sp. NP5 108 CFU/mL, 1% (v/w), kombinasi (PRO+SSBD), dan kontrol (positif dan negatif). Ikan dipelihara selama 45 hari dan diberi pakan tiga kali sehari. Pada hari ke 46, ikan pada semua perlakuan, kecuali kontrol negatif, di infeksi A. hydrophila dosis 106 CFU/mL secara intramuskular. Hasil penelitian menunjukkan bahwa kombinasi (PRO+SSBD) memberikan total eritrosit, hemoglobin, hematokrit, total leukosit dan aktivitas fagositosis lebih baik dibandingkan probitoik, SSBD, dan kontrol. Kombinasi (PRO+SSBD) mampu menekan total A. hydrophila lebih rendah dibandingkan probiotik, SSBD, dan kontrol. Selain itu, tingkat kelangsungan hidup ikan lele pada perlakuan kombinasi (PRO+SSBD) signifikan (P<0,05) lebih tinggi dibandingkan probitoik, SSBD, dan kontrol. Hasil penelitian ini bisa menjadi referensi dan aplikasi yang efektif untuk pencegahan dini infeksi A. hydrophila. Kata kunci: akuakultur, Bacillus sp. NP5, bawang dayak, probiotik, serbuk simplisia

Abstract

Vannamei shrimp is one of the most economically valuable aquaculture commodities in Indonesia. One of the pathogenic bacteria that is often found in vannamei shrimp farming is Vibrio parahaemolyticus. This study aimed to analyze the effectivity of Lactobacillus paracasei probiotics and paraprobiotics through feed with different cell densities on growth, and immune responses infected with V. parahaemolyticus. Vannamei shrimp of size 0.63 ± 0.01 were reared in containers with a stocking density of 15 shrimp per container and supplemented feed for 30 days. The research design consisted of six treatments, each with three replicates, namely (K-) feeding without supplements and injected with phosphate-buffered saline (PBS), (K+) feeding without supplements and infected with V. parahaemolyticus (104 CFU/mL), (PRI) feeding with 1% (v/w) probiotic L. paracasei with cell density of 106 CFU/mL, (PRII) 1% (v/w) probiotic L. paracasei cell density 109 CFU/mL, (PAI) 1% (v/w) paraprobiotic L. paracasei cell density 106 CFU/mL, (PAII) 1% (v/w) paraprobiotic L. paracasei cell density 109 CFU/mL. All treatments, except K-, were infected with V. parahaemolyticus (104 CFU/mL). Vannamei shrimp rearing was continued post the challenge test with V. parahaemolyticus which was conducted up to six days post injection. The results showed that feeding both probiotic and paraprobiotic L. paracasei through feed has improved growth, immune response, protein fat retention, and digestive enzyme activity of vannamei shrimp better than those of control. As the recommendation for the disease control of V. parahaemolyticus is feed supplementation with 1% (v/w) probiotic L. paracasei with cell density of 109 CFU/mL.

Abstract

Penelitian ini bertujuan untuk mengevaluasi efikasi beberapa antibiotik, termasuk oksitetrasiklin, enrofloksasin, gentamisin, ampisilin, dan eritromisin, terhadap isolat Pasteurella multocida dari sapi. Kerentanan antibiotik dinilai menggunakan metode difusi cakram. Hasilnya mengungkapkan sensitivitas P. multocida yang konsisten terhadap enrofloksasin dan gentamisin, sedangkan tiga dari lima isolat tetap rentan terhadap oksitetrasiklin. Sebaliknya, semua isolat menunjukkan resistensi terhadap eritromisin dan ampisilin. Khususnya, galur Tipe A menunjukkan resistensi yang lebih tinggi terhadap oksitetrasiklin daripada galur Tipe B, mungkin karena tekanan selektif yang berbeda. Temuan ini menggarisbawahi enrofloksasin dan gentamisin sebagai pilihan terapi yang paling efektif untuk septikemia hemoragik pada sapi, mengingat aktivitas antibakterinya yang kuat terhadap P. multocida.

Abstract

Ovariohisterektomi banyak dilakukan pada hewan kecil dan sering kali mengalami komplikasi berupa luka yang terbuka. Studi ini mengevaluasi dua teknik jahitan, yaitu jahitan intradermal kontinu yang terkubur (BCID) dan jahitan terputus sederhana (SI), pada 42 kucing betina menggunakan jahitan nilon yang tidak dapat diserap. Berat, panjang sayatan, panjang jahitan, dan waktu penutupan juga dianalisis. Penilaian pascaoperasi pada 18-24 jam dan 5-7 hari meliputi pemantauan pembengkakan, eritema, eksudat, dan terbukanya luka. Hasilnya menunjukkan insiden komplikasi yang jauh lebih tinggi, terutama terbukanya luka, pada kelompok SI. Akibatnya, BCID direkomendasikan karena tingkat komplikasinya yang lebih rendah dan risiko infeksi akibat trauma diri yang berkurang.

Abstract

Antibiotic resistant coagulase-negative staphylococci (CoNS) have been reported around the world. The aim of this study was to determine the antimicrobial susceptibility of CoNS isolated from red–tailed racers. Samples were swabbed from the oral cavity of 5 wild caught red–tailed racers, and were identified with biochemical test using the Kirby–Bauer disc diffusion test interpreted by referring to Clinical and Laboratory Standards Institute. The results obtained 4 species of CoNS isolated from swab samples including S. sciuri, S. xylosus, S. lentus, and S. kloosii. The antibiotic resistance test of S. xylosus, S. sciuri, and S. lentus showed susceptibility to amoxicillin, gentamicin, erythromycin, bacitracin, vancomycin and oxacillin, but resistance towards penicillin G.
