Usaha budidaya ikan lele dumbo memiliki nilai ekonomis yang tinggi karena merupakan salah satu komoditas hasil perikanan yang potensial untuk diekspor. Penelitian ini dilaksanakan pada Bulan Mei hingga Bulan Juni 2015 dan dilaksanakan di Laboratorium Fisiologi Fakultas Kedokteran Hewan Universitas Syiah Kuala, Laboratorium Akuatik Fakultas Kedokteran Hewan Universitas Syiah Kuala dan laboratorium Mikrobiologi BBI Ujong Batee Aceh Besar. Tujuan penelitian ini adalah untuk mengetahui efektifitas bubuk rumput laut merah (Gracillaria sp) sebagai imunostimulan infeksi bakteri Streptococcus iniae pada ikan lele dumbo (Clarias gariepinus). Metode yang digunakan pada penelitian ini yaitu secara eksperimental dengan rancangan acak lengkap (RAL) non faktorial dengan empat perlakuan tiga kali ulangan. Perlakuan adalah pemberian bubuk rumput laut merah secara perendaman dengan dosis perlakuan A (125 mg/l), perlakuan B (100 mg/l), perlakuan C (75 mg/l) dan perlakuan D (kontrol) tanpa perendaman dengan bubuk rumput laut merah. Hasil penelitian menunjukkan perendendaman bubuk rumput laut merah terhadap ikan lele dumbo dengan dosis yang berbeda berpengaruh terhadap pencegahan infeksi bakteri Streptococcus iniae pada ikan lele dumbo. Pemberian bubuk rumput laut merah untuk meningkatkan sistem imun ikan lele dumbo menunjukkan pengaruh sangat nyata terhadap kelangsungan hidup, dimana F hitung (45.111) > F tabel 0,01 (7.59). Perlakuan terbaik terdapat pada perendaman dengan bubuk rumput laut merah dengan dosis 100 mg/l dengan persentase kelangsungan hidup sebesar 83,33%. Selanjutnya kelangsungan hidup terendah terdapat pada perlakuan D (kontrol) tanpa perendaman dengan bubuk rumput laut merah dengan persentase kelangsungan hidup 23,33 % dan mengalami gejala klinis yang paling buruk. Total leukosit pada ikan lele dumbo meningkat pada saat diberi perlakuan perendaman dengan bubuk rumput laut merah dan pada saat uji tantang dengan bakteri Streptococcus iniae. Kualitas air selama penelitian berada pada kondisi yang optimal untuk pertumbuhan ikan lele dumbo dengan kisaran Do 5,0-6,4 ppm, suhu 28-30 0C dan pH 7,0-7,3.Catfish farming has a potential economic value for its commodity in export trading. This study was conducted in May until June 2015 at Physiology Laboratory and Aquatic Laboratory 0f Veteranary Faculty, Syiah Kuala University, then at Laboratory of BBI Ujung Batee. Aceh Besar. The purpose of this study was to determine the effectiveness of red seaweed powder (Gracillaria sp) as immunostimulant againts Streptococcus iniae bacterial infection in catfish (Clarias gariepinus). The method used in this study was experimental method by using a completely randomized design (CRD) non factorial with four treatments of three replications. The factor of experiment was different dosages of red seaweed powder throld soaking treatment. Those different dosages were A (125 mg / l), treatment B (100 mg / l), treatment C (75 mg / l) and treatment D (control) without the red seaweed powder. The results showed that red seaweed powder word give prevention on bacterial infection in catfish. Aplication of red seaweed powder to the immune system of catfish showed highly significant effect on survival rate where F count (45,111)> F table 0,01 (7,59). The hignest survival rate was obtainied from red seaweed powder at a dose of 100 mg/l with a survival rate 83.33%. Furthermore, the lowest one was from the treatment D (control) without soaking by red seaweed powder which survival rate was 23.33% then its clinical symptoms were the worst one. Total leukocytes of catfish inereased when the fish was red seawed powder treated and bacterial challenge test. Water quality during the study was in optimal conditions for the growth of the catfish which the parameters water DO 5.0 to 6.4 ppm, a temperature 28-30 0C and pH 7.0 to 7.3.

Abstract Introduction Herpetic whitlows in infants are rare. Previous authors only reported individual case reports. We present a case series of six infants. Materials and Methods This is a retrospective study of six cases of herpetic whitlows in infants seen by the senior author (MMA) over the past 23 years (1995–2017 inclusive). The following data were collected: age, sex, digit involved in the hand, mode of transmission, time of presentation to the author, clinical appearance, presence of secondary bacterial infection, presence of other lesions outside the hand, method of diagnosis, treatment, and outcome. Results All six infants initially presented with classic multiple vesicles of the digital pulp. In all cases, there was a history of active herpes labialis in the mother. Incision and drainage or deroofing of the vesicles (for diagnostic purposes) resulted in secondary bacterial infection. Conclusion The current report is the first series in the literature on herpetic whitlows in infants. We stress on the mode of transmission (from the mother) and establishing the diagnosis clinically. In these cases, no need for obtaining viral cultures or polymerase chain reaction; and no medications are required. Once the vesicles are disrupted, secondary bacterial infection is frequent and a combination of oral acyclovir and intravenous antibiotics will be required.

Background: Natural preservatives are compounds produced by natural ingredients that can suppress bacterial growth and development. Natural preservatives are carried out because most of the preservatives circulating are chemicals and unsafe for the body. One of the natural preservatives is by using garlic extract (Allium sativum L).  Objective: This study is aimed to determine the effectiveness of the antibacterial garlic (Allium sativum L) as a natural preservative in fresh African catfish (Clarias gariepinus).  Method: This research used the Pour Plate iroculation method. African catfish (Clarias gariepinus) which is soaked with garlic (Allium sativum L) with a concentration of 7%, 14% and 21% for 30 minutes, then the fish will be kept at room temperature with a storage period of 24 hours and 48 hours and calculated growth in bacterial numbers with the Colony counter.  Result: Based on the research result, it was found that garlic extract (Allium sativum L) can obstruct the effectiveness of antibacterial in African catfish (Clarias gariepinus) at a concentration of 14%.
