Abstract

The outbreak of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which causes coronavirus disease 2019 (COVID-19), has spread worldwide and as a result, the World Health Organization (WHO) declared it a pandemic. At present, there are no approved vaccines against SARS-CoV-2. Therefore, the aim of this study was to predict epitope-based vaccines using bioinformatics approaches and phylogenetic tree construction of SARS-CoV-2 against the backdrop of the COVID-19 pandemic. In this study, we employed 27 isolates of SARS-CoV-2 spike glycoprotein genes retrieved from GenBank® (National Center for Biotechnology Information, USA) and the GISAID EpiCoV™ Database (Germany). We analyzed the candidate epitopes using the Immune Epitope Database and Analysis Resource. Furthermore, we performed a protective antigen prediction with VaxiJen 2.0. Data for B-cell epitope prediction, protective antigen prediction, and the underlying phylogenetic tree of SARS-CoV-2 were obtained in this research. Therefore, these data could be used to design an epitope-based vaccine against SARS-CoV-2. However, the advanced study is recommended for confirmation (in vitro and in vivo).

Abstract

This study aimed to compare the immunogenicity between the whole virus and protein S of both local strain I-147 and Massachusetts strain of Infectious bronchitis virus with indirect ELISA. 24 healthy mice are divided into four groups with six mice in each group that are: P1) a group of mice that are vaccinated with S protein (spike glycoprotein) of local strain Infectious Bronchitis virus; P2) a group of mice that are vaccinated with S protein (spike glycoprotein) of Massachusetts strain Infectious Bronchitis virus; P3) a group of mice that are vaccinated with the whole virus of local strain Infectious Bronchitis virus; P4) a group of mice that are vaccinated with the whole virus of Massachusetts strain Infectious Bronchitis virus. The results of this research are Optical Density (OD) values of each treatment, then to be analyzed using One Way ANOVA and followed by Duncan Multiple Range Test 5% and T-test. The results show that there are differences in immunogenicity between the whole virus and S protein in both the local strain and Massachusetts strain of Infectious bronchitis virus. The OD value of the whole virus in the two strains has a significant difference from the OD value of the protein S antigen in both strains, both in the serum taken at week 2 and week 4 post-vaccination.

Abstract

This study aimed to detect the presence of eae gene in E. coli from chicken meat sold at the traditional market Surabaya. Identification of bacteria was carried out in several stages, inoculated on pre-enrichment media using Buffered Peptone Water (BPW), planting on Levine's Eosin Methylene Blue Agar (L-EMB) media, suspected colonies on L-EMB were subjected to Triple Sugar Iron Agar (TSIA) and Indol test for the confirmation of E. coli. The confirmed E. coli isolates were tested by Polymerase chain reaction (PCR) to determine the presence of the eae gene. The results showed that E. coli could be identified in 28 out of 100 (28%) chicken meat samples, and eae gene was detected in three E. coli isolates (11%).

Abstract

This research aimed to know the antibacterial activities of bidara leaf extract against Staphylococcus aureus isolated from mastitis cases. The isolate was identified before the antibacterial test. This study was done by five times repetitions on Mueller Hinton Agar. The concentrations used in this study were 30%, 40%, and 50% of bidara leaf extract then a blank disc was dipped into each concentration. Tetracycline disc was used as a positive control and aquadest was used as a negative control. The diameter of the clear zone was measured using calipers after incubation for 24 hours at 37℃. The results showed significant differences (p<0.05) between the positive control (K+), negative control K (-), and the concentration group. However, each concentration of bidara leaf extract showed insignificant differences in the diameter of the clear zone. It could be concluded that bidara leaf extract has antibacterial activities against Staphylococcus aureus isolated from mastitis cases.

Abstract

The quality of fresh milk based on SNI 2011 regarding fresh milk requirements includes physical, chemical and the number of microorganisms. One of the physical properties of milk can be seen from the density test. The chemical properties of milk can be seen from the lactose and fat rate. The lactose test is by means of titration of the filtrate resulting from filtering milk which is free from any content other than lactose. Density test using a lactodensimeter. Fat test using the Gerber method. From the results of research on the quality of cow's milk which was carried out using the lactose test approach, density and fat obtain average results of 3.98% of lactose rate, 1.0259 g/ml of density and 2.7% of the at rate in VUC Kertajaya is good and close to the criteria according to SNI 2011. This can affect the selling price of milk from farmers in VUC Kertajaya.

Abstract

Broiler are popular meat-producing birds in Indonesia because they contain high levels of animal protein. Apart from being used in the treatment of infectious diseases, antibiotics are also used as antibiotic growth promoters (AGP). However, the use of antibiotics as feed additives has been prohibited, a natural substitute for AGP is katapang leaves (Terminalia catappa L.). This study aims to determine the effect of administering katapang leaf extract (Terminalia catappa L.) on the number and type of leukocytes in broiler. This study used 24 Cobb strain broiler which were divided into four treatment groups, each group consisting of six replications. The treatment groups were P0 = only given 1% CMC-Na solution, P1 = Katapang leaf extract solution with 5% concentration, P2 = Ketapang leaf extract solution with 10% concentration, P3 = Katapang leaf extract solution with 15% concentration. The treatment is given orally with a syringe, given to chickens aged 21–35 days. At the end of the study, 2 ml–3 ml of blood is taken from the brachial vein. Data were analyzed using Analysis of Variance and continued with Duncan's Multiple Range Test

Abstract

Simian Immunodeficiency Viruses (SIV) have been found to naturally infect African nonhuman primates (NHP). This causative agents are important and one of the special interest as the root cause of the HIV/AIDS pandemic, one of the most threatening infectious diseases worldwide. The aim of this study was to design an epitope-based vaccine using bioinformatics approaches of the circulating SIV in Kenya, Africa. In this study, we used 17 partial SIV envelope glycoprotein genes retrieved from GenBank® (National Center for Biotechnology Information, USA). We analysed the candidate epitopes using the Immune Epitope Database and Analysis Resource. Then, we performed the protective antigens prediction usingVaxiJen. Interestingly, this study revealed the data of B cell epitope prediction, protective antigens prediction, and molecular phylogenetic of circulating SIV in Kenya, Africa. In sum, this study can be used to design a novel epitope-based vaccine against SIV. We suggest further studies to conduct confirmatory experiments (in vitro and in vivo).
