Abstract

Bovine respiratory syncytial virus (BRSV) is highly prevalent in cattle. It is a major viral cause of bovine respiratory disease complex, which is associated with morbidity, mortality and substantial economic impact. Currently available treatments are only symptomatic, but no specific treatments are available for BRSV infection. This study aimed to identify new antiviral agents against BRSV, which could be used to control bovine respiratory disease complex in cattle with Indonesian herb extracts. Ethanol extracts prepared from Indonesian herbs including Andrographis paniculata, Phyllanthus niruri, Curcuma aeruginosa, and Curcuma xanthorrhiza were evaluated for anti-BRSV activity in A549 cells. The cytotoxicity of the herb extracts was evaluated using a CCK-8 cell viability assay. Antiviral activities of the herb extracts were examined using cell activity and cytopathic assays. The effect on virus production was evaluated by qRT-PCR and plaque-formation assays. Extracts of Curcuma xanthorrhiza (125 μg/ml), Andrographis paniculata (250 μg/ml), and Phyllanthus niruri (62.5 μg/ml) inhibited BRSV activity in A549 in pre-, simultaneously-, and post-infection treatment assays, respectively, as measured by the selective index. Reduction of BRSV activities by the herb extracts correlated with inhibition of viral gene expression and inhibition of plaque formation in a concentration- and time-dependent manner. Our findings suggest that these herb extracts have sufficient potency to be used not only as a therapeutic agent but also as a preventive agent to limit BRSV infection.

Abstract

To evaluate the immune response of a rabbit model to polysaccharide capsules of Streptococcus pneumoniae after primary and booster immunization with pneumococcal conjugate vaccine. Rabbits were immunized with 0.25 ml of the 13-valent pneumococcal conjugate vaccine (PCV13) on Day 0, 7, and 14. Blood of rabbits was collected to measure the specific antibodies against the native polysaccharide capsules of S. pneumoniae serotypes 6B (Anti-Pn6BPS antibodies) and 19F (Anti-19FPS antibodies) using enzyme-linked immunosorbent assay (ELISA). The specific anti-Pn6BPS and anti-Pn19FPS antibodies in the immunized group increased significantly compared to the control rabbit after immunization (P<0.05). The highest titer of anti-Pn6BPS and anti-Pn19FPS antibodies were obtained on Day 21 and Day 28, respectively. The third immunization on Day 21 is a fairly high increase in specific antibodies against polysaccharide type 6B and type 19F. The highest antibody titers against polysaccharide capsules of S. pneumoniae were obtained after booster immunization.

Abstract

Polytyrene nanoplastics (NPs) (<1 µm) have high toxicity when entered and accumulated in cells. NPs accumulation causes oxidation stress, thus increasing reactive oxygen species (ROS) production, resulting in necrosis or apoptosis, as well as affecting endogenous antioxidant activity, such as superoxide dismutase (SOD) and catalase (CAT). Cinnamomum burmanni plant contains flavonoids, cinnamaldehyde, phen, and olic acid, potentially exogenous antioxidants. The study aims to analyze the potential of C. burmanni leaf extract for SOD and CAT levels, sperm quality, epithellia tubulus thickness, tubulus seminiferus diameter, and number of spermatogenic Rattus norvegicus cells exposed to NPs. Twenty-five male R. novergicus are divided into five groups (n = 5): two controls (without and with NPs) and three groups (combination of NPs and variations in extract concentrations of 100, 200, and 400 mg/kg. The SOD and CAT levels were measured with an ELISA kit. The histology was observed by counting the spermatogenic cells, measuring the epithellia thickness, and tubulus seminiferus diameter. The sperm motility, viability, and sperm count were observed to determine the sperm quality. Leaf extract of C. burmanni treatment with different concentrations not significantly increased SOD levels but significantly decreased the levels of CAT (P<0.05). The addition of C. burmanni leaf extract significantly increased the spermatogenic cell count, epithelia tubulous thickness, sperm viability, and sperm count (P<0.05), while sperm motility and tubulous seminiferous diameter not significantly increased. According to the results, C. burmanni leaf extract has antioxidant potential against the toxic effects of NPS.

Abstract

Vector-borne disease such as Dengue Hemorrghagic (DHF), transmitted by Aedes aegypti and Aedes albopictus, remain a significant public health concern in Indonesia. Controlling these disease often involves insectides; however, the negative impact of chemical insecticides have prompted interest in organic alternatives derived from plants. Certain weeds, including cogon grass (Imperata cylindrica), wild sugarcane (Saccharum spontaneoum), and needle grass (Andropogon aciculatus), have shown potential as botanical insecticides. Research findings showed that weed root extracts significantly affect larval mortality rate of Ae. Aegypti. At 1000 ppm, larval mortality was significantly higher compared to 100 ppm and the control, while treatments of 1 ppm and 10 ppm showed similar results to the control. Probit analysis revealed that I. cylindrica root extract achieved an LC50 of 974.99 ppm within 24 hours, indicating it could kill 50% of Ae. Aegypti larvae. Within 48 hours, the LC50 dropped to 889.20 ppm. Toxicity tests further revealed significant differences in Ae. Aegypti egg-laying abilities when treated with extracts. Analysis of variance yielded p-values of 0.000 for egg hatching within 72 and 96 hours, highlighting significant differences across samples. These findings suggest the extracts influence mosquito reproduction, warranting further studies to assess the quality of egg hatched from larvae exposed to these treatments. The potential of botanical insecticides derived from weeds represents a promising step toward sustainable mosquito control in the fight against vector-borne diseases.

Abstract

The rice gall midge, Orseolia oryzae, and the cogongrass gall midge, O. javanica, cause gall formation on rice and cogongrass (alang-alang) (Imperata cylindrica). Two different species parasitize these two gall midges but closely related platygasterids, Platygaster oryzae on the rice gall midge and P. orseoliae on the cogongrass gall midge. Both the gall midges and their parasitoids are often found in the adjacent area, raising a question about the relationship between the two gall midges and their parasitoids. This research aims to study the molecular identity of the rice and cogongrass gall midges, along with their platygasterid parasitoids, based on partial sequences of the mtCOI gene. Samples were collected from rice and cogongrass in the adjacent area in Cianjur, West Java Province, and a rice field with no cogongrass in Bogor, West Java Province. Successful DNA amplification was achieved using universal primers for mtCOI. Nucleotide sequencing analysis revealed that the rice gall from Bogor and Cianjur shared 100% similarity and 93.2-99.3% similarity with the rice gall from other countries. Notably, the parasitoids P. oryzae collected from rice in Bogor and Cianjur shared 97.2% similarity with P. orseoliae collected from cogongrass in Cianjur. These findings suggest that the platygaster parasitoids associated with the rice gall and the cogongrass gall midges are identical, serving as potential natural enemies for both pests. This study represents the first molecular identification report of rice and cogongrass gall midges and their platygasterid parasitoids from Java Island, Indonesia.

Abstract

Long-tailed macaques (Macaca fascicularis: LTMs) are widely distributed, adaptable primates commonly used as animal models in biomedical research. At primate facilities such as the Dramaga Captive Breeding Facility and the Tinjil Island Natural Habitat Breeding Facility at the Primate Research Center, IPB University, LTMs experience varying diets depending on their captive or semi-wild environments. At Dramaga Captive Breeding Facility, LTMs housed in individual and group cages are provided with different feeding regimens, whereas the semi-wild LTMs on Tinjil Island feed primarily on natural food sources with occasional, very modest provisioning of bananas. Our study's objective is to evaluate these diets' influence on the gut microbiota and overall health of LTMs. Through comparative analysis of fecal microbiomes using 16S rRNA sequencing, we identified distinct gut microbiota profiles between captive and semi-wild LTMs. Semi-wild LTMs displayed a predominance of Proteobacteria, notably Succinivibrio, associated with a high-fiber diet derived from wild plant consumption. In contrast, captive LTMs housed in individual and group cages exhibited dominance of Firmicutes and Bacteroidota, respectively. These findings suggest that diet is pivotal in shaping gut bacterial profiles, potentially impacting metabolic functions. Our study provides insight into the relationship between certain diets and gut bacterial composition in LTMs across different breeding facilities at the Primate Research Center, IPB University, thereby offering valuable implications for LTMs' welfare and management strategies.

Abstract

Concrete is a common building material and is very vulnerable to cracking caused by unstable temperature/humidity. Concrete crack repair can be done by using microorganism substitution that can produce CaCO3 (calcite) compounds that can be used as an environmentally friendly method in improving structural formation and increasing the strength and durability of concrete, one of which is using ureolytic bacteria. This study aimed to isolate and characterize ureolytic bacteria isolates and then to assess the calcite precipitation potential of ureolytic bacteria isolates from landfills. The ureolytic bacterial isolates were grown on NB-U/Ca and tap water medium. Analysis of Calcite Structure using Fourier Transform Infra-Red (FTIR), and molecular identification using 16S rRNA gene sequences. Bacterial isolate SP. 48 were able to grow and produce calcite in both media, especially in tap water medium. FTIR results showed that the precipitates produced by bacterial isolates on both mediums had strong absorption peaks, which were detected to be calcite. Molecular identification using the 16S rRNA gene sequence showed that the isolate is Bacillus albus. B. albus is a proteolytic bacterium collected from landfills that was proven to be a calcite-producing bacterium, a new finding in this study. B. albus can grow and produce calcite in a tap water medium with low pH. This finding can be used as an alternative to overcome concrete cracks and increase the strength and durability of concrete. This bacterial isolate could be developed as a biocement candidate.

Abstract

Topical use of oxybenzone, commonly found in sunscreens, can be absorbed by the skin, and long-term use may cause endocrine disruption, cancer, and teratogenic effects. However, its potential teratogenic effects on embryonic development have not been well-studied. This study aims to determine the impact of oxybenzone exposure on the early stage of embryonic development. Chicken embryos aged 72 hours (20 Hamburger-Hamilton/HH stage) were exposed to a pure oxybenzone for 24 hours at varying concentrations (0, 1, 5, 10, and 20 ppm), each group consisting of 3 embryos. Embryo preparations were made using the wholemount method. Morphological abnormalities were observed with a stereo microscope, and descriptively morphometric measurements were analyzed using ImageJ software. Statistical analysis used One-way ANOVA and Tukey’s test for normally distributed data, while Kruskal-Wallis H and Mann-Whitney U test for non-normally distributed data. This study found that oxybenzone significantly enlarged the embryo, telencephalon, and eye. Several abnormalities were observed in the embryos exposed to oxybenzone, including incomplete closure of the anterior neuropore, concavity in the anterior and lateral of the mesencephalon, and depressions in the tail bud. This study concludes that oxybenzone acts as a teratogen, causing abnormalities in embryonic development, particularly in the central nervous system.

Abstract

The transition from fossil fuels to sustainable renewable energy is currently growing rapidly. Euglena sp. can be the source of biofuel. Molasses, in addition to Euglena sp., can increase the levels of paramylon and wax esters produced. Therefore, this study aims to analyze cell growth, lipid profile, and wax ester content of Euglena sp. cultivated under mixotroph conditions with molasses. Euglena was cultivated under mixotrophic conditions with the addition of various concentrations of molasses (0, 10, 15, and 20 g/L) until the final log phase. Then, measurements were made on cell density, levels of lipids, proteins, and paramylon to measure the growth and metabolites profile of Euglena sp., along with lipid profile and wax ester analysis using GC-MS. The results of the study showed that 10 g/L molasses increased Euglena growth (SGR 0.1736± 0.0213 mg/ml) and carbohydrate (0.426 mg/ml) but reduced lipid accumulation (2.29 mg/ml). This treatment provides the best result before control. Molasses does not increase carbohydrates and protein but increases paramylon accumulation. The GC-MS assay detected more lipid profiles and concentrations of each lipid type in non-molasses-treated Euglena sp. compared to molasses-treated. Euglena was cultivated on molasses, which was dominated by palmitic acid and myristyl myristate with the absence of PUFA-type fatty acids in the cells, while the untreated ones were dominated by stearic acid and myristyl myristate. Thus, 10 g/L supplementation of molasses is the most effective treatment compared to others.

Abstract

Bird vocalizations are crucial for communication and adaptation to environmental changes. As forests are converted to agriculture, agroforestry plays a key role in conserving biodiversity. This study examines vocal bandwidth variations in four bird species-Common Tailorbird (Orthotomus sutorius), Sooty-headed Bulbul (Pycnonotus aurigaster), Olive-backed Sunbird (Cinnyris jugularis), and Small Minivet (Pericrocotus cinnamomeus)-across three coffee agroforestry sites in Jember, Indonesia: Silo, Kluncing, and Kaliwining. The study explores how vegetation structure influences vocal adaptations using sound recordings, vegetation surveys, the Kruskal-Wallis test, and Pearson correlation analysis. Results show significant vocal bandwidth differences in Common Tailorbird and Sooty-headed Bulbul. Common Tailorbird exhibited the highest bandwidth variation in Silo (2.85 kHz), followed by Kluncing (2.30 kHz) and Kaliwining (1.10 kHz) (p<0.001). Similarly, Sooty-headed Bulbul showed significant variation, with the highest bandwidth in Silo (3.1 kHz), Kaliwining (3.5 kHz), and Kluncing (2.7 kHz) (p<0.001). However, bandwidth variation in Olive-backed Sunbird (p = 0.12) and Small Minivet (p = 0.0014) was not significant. Pearson correlation analysis indicated a strong but non-significant relationship between vegetation structure (Importance Value Index) and Sooty-headed Bulbul presence (R² = 0.8999, p = 0.059). These findings suggest that while vegetation influences some species, other factors like resource availability or human activity may also shape vocal adaptations. This study enhances understanding of bird communication in agroforestry, supporting biodiversity conservation and sustainable land management.
