Sweet basil is one of the most popular culinary, medicinal, and fragrance herbs in Mediterranean, Asian, and Western countries. This study aims to increase the growth performance of sweet basil via different concentrations of chitosan, which is applied at three growth stages. The study was arranged in a factorial randomized complete block design with four replications. The plants were divided into three growth stages, which were the vegetative stage (S1), the reproductive stage (S2), and both the vegetative and reproductive stages (S1 + S2). Those plants were then treated with four different concentrations of chitosan (0, 2, 4, and 6 ml/L) either on S1, S2, or S1 + S2. The results indicated that plants treated with chitosan at S1 showed greater performance. Chitosan concentration of 4 ml/L produced greater plant height (55.09 ± 1.75 cm/plant), stem diameter (11.08 ± 0.89 mm/plant), and a number of leaves (296.57 ± 11.61 leaves/plant). It is also interesting to observe that the lowest chitosan concentration was non-significantly different, with 4 ml/L at S1 in some parameters. Plants in those treatments showed the highest average length of internode, number of branches, total root length, average root diameter, total root volume, and total root surface area. Besides, correlation analysis proved that all the parameters significantly correlated positively. As the concentration of 4 ml/L showed a superior effect, especially on the number of yields, thus it is recommended for growers to apply chitosan at 4 ml/L during S1.

Various attempts have been made to increase rice production, including breeding for high-yielding and stress-tolerant varieties, a good crop management system, and increased agricultural input in rice production. Soundwave stimulation has been demonstrated to affect plant growth; thus, this method can be employed in the current rice production methods to improve yield. The study aims to determine the effects of different sound wave qualities on the general growth, physiological, and morphological of rice seedlings. Rice seeds of the MR219 variety were grown under a glasshouse condition in a nested design with five replications and were stimulated with various sound wave frequencies. Various sound wave frequencies, 380, 359, 357, 353, and 350 Hz, were obtained by placing the pot at varying distances (80, 160, 240, 320, and 400 cm, respectively) from the sound source, except control treatment. There were significant effects in some of the parameters: plant height, leaf physiology, and stomatal pore and length when treated with varying sound wave qualities. Plants can be stimulated with 380, 357, and 350 Hz soundwaves frequencies for the best photosynthetic experience. In addition, 359 Hz of sound wave stimulation resulted in high water use efficiency, which is beneficial in improving crop performance in drought conditions. Thus, it was demonstrated that the sound wave stimulation method has the potential to enhance rice performance in addition to the regular agronomic practices of rice production in farmers’ fields.

Mastitis is one of the diseases that cause economic losses worldwide due to the reduction in milk yield and the high treatment costs in dairy buffaloes. Although antibiotics are the mainstay treatment for this disease, the overuse of antibiotics has resulted in the emergence of antimicrobial resistance in animals and humans. Hence, this study aims to review and assess the available literature on bubaline mastitis in Asia. The prevalence of subclinical mastitis was higher in dairy buffaloes than in clinical mastitis, especially in Pakistan. Bubaline mastitis was commonly detected using the California mastitis test, surf field mastitis test, somatic cell count, and bacterial culture. In Asia, farm management and host factors were the primary causes of bubaline mastitis risk factors. Mastitis in buffaloes caused alterations in milk composition, such as increasing lactose levels, somatic cell count, and the presence of bacteria in the milk. However, protein, fat, and solid non-fat level variations were also affected by other factors such as the stage of lactation, breed, and age. The most prevalent isolated bacteria in bubaline mastitis milk samples were coagulase-negative staphylococci, Staphylococcus aureus, Streptococcus spp., and Escherichia coli. Most showed high resistance toward penicillin, amoxicillin, ampicillin, and streptomycin. The antimicrobial susceptibility of causative agents in Asia varies depending on the usage of common antibiotics to treat bubaline mastitis in each country. This review will help to understand bubaline mastitis better, although studies are limited in many Asian countries.

Veterinary hospitals are important locations for various sick and immunocompromised animal patients. These centers may act as reservoirs for nosocomial diseases such as Salmonella infection, one of the most common causes of healthcare-associated infections in veterinary hospitals. The study was performed at the Large Animal Ward (LAW), University Veterinary Hospital, Universiti Putra Malaysia, to assess the environment’s degree of Salmonella spp. contamination. Environmental samples were obtained from various floor and surface areas in the LAW using sterile, moistened gauze. Salmonella spp. was determined using conventional bacteriological culture on all samples. Positive Salmonella isolates were subject to antimicrobial sensitivity testing. A total of 6 out of 135 (4.4%) samples were found to be positive for Salmonella spp., with 5/116 (4.3%) samples obtained from the ward environment and 1/19 (5.3%) obtained from reusable equipment. Antimicrobial sensitivity testing revealed three resistance profiles: all isolates were resistant to penicillin and enrofloxacin, one isolate was resistant to streptomycin, and one was resistant to gentamicin. The results indicate that animal treatment areas within the LAW can become contaminated with Salmonella spp. This study highlights the importance of improving biosecurity programs to prevent nosocomial diseases in patients and the hospital environment.

Polystyrene waste pollutes the environment and poses a significant health risk to humans, animals, and marine ecology. This study aims to evaluate the effectiveness of degradation on expanded (EPS) and extruded (XPS) polystyrene with different diets using superworms (Zophobas atratus larvae) obtained in Malaysia. The growth and development of the larvae after consumption of EPS and XPS and the gut microbial community changes in response to high polystyrene consumption diets were also identified. The oatmeal, wheat bran, and cornmeal were used as supplement diets and showed significantly enhanced EPS and XPS consumption and degradation compared to sole diet treatment. Gel permeation chromatography was carried out using egested frass of Z. atratus larvae to characterize depolymerization of EPS and XPS, indicating a significant reduction in the average molecular weight and average molecular weight. The highest reduction occurred in the presence of oatmeal. Proton nuclear magnetic resonance and Fourier transform infrared spectroscopy analyses indicated functional group changes and chemical modification occurred with depolymerization and partial oxidation of EPS and XPS. The larvae length increased, while the number of instars and duration of larvae became shorter with the addition of supplement diets. Oatmeal is predominantly effective among other supplements in assisting Z. atratus larvae with EPS and XPS degradation. The results of this study support the ubiquity of polystyrene biodegradation in Z. atratus and the next-generation sequencing studies. Kluyvera sp., Klebsiella sp., and Enterobacter sp. were found to be strongly associated with degrading EPS and XPS polystyrene with oatmeal as a supplemental diet.

Infectious bronchitis virus (IBV) in chicken (Gallus gallus) is the most common and well-studied Avian coronavirus (ACoV) in avian species. The study aims to molecularly characterize ACoV isolate of selected bird species other than chicken obtained from the archived samples of field diagnostic cases in the Northern Zone Veterinary Laboratory (MVZU), Malaysia. Twelve archived virus isolates from 2013 to 2019 were amplified using selected primers on the 3’ UTR gene and S1 gene for oligonucleotide sequencing. These sequences were then molecularly characterized and compared with common IBV strains in chicken to determine the genetic diversity of the virus among selected avian species. Subsequent analyses of the nucleotides amplified on 3’ UTR conserved region of 12 selected ACoVs isolates originating from peacocks (Pavo cristatus), turkey (Meleagris), jungle fowl (Gallus gallus spadiceous), guinea fowl (Meleagris gallopavo domesticus), goose (Anser anser domesticus), love bird (Agapornis), macaw (Ara macao), and bird (species unidentified) are classified as belonging to the gammacoronavirus (Gamma-CoV) genus and have a high degree of homology. The S1 complete gene sequence analyses of guinea fowl and jungle fowl showed that both ACoV isolates are Gamma-CoV and under genotype I and GI-13 lineages. Both are identified as having a high similarity of 98% and 99%, respectively, with IBV vaccine strain 4/91 (AF093793). Due attention should be given to ACoVs strains, especially the IBV vaccine strains detected in other bird species, because there is a high probability that other bird species could be the source of pathogenic ACoV infection in general and IBV infection in chickens, as reported in other countries.

The tissue expansion technique is one of the most important innovations in skin reconstructive surgery in human and veterinary medicine. This study investigated horses’ physiological and behavioural responses to subcutaneous implantation of a unidirectional self-inflating anisotropic tissue expander. The tissue expanders were subcutaneously implanted on six horses at three different locations: the frontal region of the head, the lateral side of the right shoulder, and the dorsomedial part of the cannon region of the right forelimb. Prior to the tissue expander implantation, each horse was clinically examined, and the observed vital parameters and behaviour were recorded as baseline data. For six days post implantations, the horses were clinically examined, implantation sites monitored, and the horse’s behaviour was recorded both during the day by visual observation and at night with a video camera. The results showed that all horses tolerated the subcutaneous gradual skin expansion by implantation of the tissue expanders, and all surgical sites healed without any complications. The implantation of the tissue expanders does not affect the vital parameters or overall horse behaviour either during the day or at night. In conclusion, the subcutaneous implantation of unidirectional anisotropic tissue expanders in horses resulted in successful skin growth with no physiological and psychological discomfort; hence skin expansion is a good option to be considered when pursuing equine skin reconstructive surgery.

This study examined the effect of locule position and thawing duration on the physicochemical and nutritional characteristics of intact cryo-frozen Musang King durian fruit. Cryo-frozen durian that had 5 locules was thawed for 2 and 18 hr, and the fruitlets of each locule were analysed for colour (L*, a*, b*, C*, and h), firmness, soluble solids concentration (SSC), titratable acidity (TA), pH, ascorbic acid (AA), total phenolic content, total flavonoid content, 1,1-diphenyl-2-picrylhydrazyl, 2,2′-azinobis-(3-ethylbenzothiazoline-6-sulfonic acid and ferric reducing antioxidant power assay (FRAP). Results show that L* and a* of pulp colour, firmness, SSC, pH, TA, AA, and FRAP of cryo-frozen durian fruit were affected by a significant interaction between locule position and thawing duration. It implies the postharvest quality of intact cryo-frozen durian fruitlet distinct from each other due to their locule position and thawing duration.

The chalcone synthase (CHS) gene families are known to be conserved in plants and have been well-studied in many plants, and they have an important role in the physiological and biological processes of plants. One of the studied CHS gene families is the CHS1 gene. CHS1 gene is known for its function in the flavonoid biosynthetic pathway. However, not many studies have been reported on the CHS1 gene in the Commelinids clade, especially the evolution of this gene within three families: Zingiberaceae, Costaceae, and Poaceae. Thus, this study aimed to perform a preliminary in silico comparative analysis of the CHS1 gene across these three families. Through this in silico comparative analysis, 20 partial sequences of the CHS1 gene, which are restricted to 565 bp regions, were analysed. The partial sequences were extracted from the National Center for Biotechnology Information database comprised of 16 Zingiberaceae species, three Costaceae species, and one Poaceae species. From the analysis, these targeted regions showed a low polymorphic site (18.23%) with 103 positions of single nucleotide polymorphisms and three mutations (substitution, insertion, and deletion). Meanwhile, phylogenetic analysis showed no clear evolutionary pattern within the three studied families. In conclusion, the studied partial sequences of the CHS1 gene in Zingiberaceae, Costaceae, and Poaceae showed that the gene is conserved within the Commelinids clade. Further studies to understand the consequences of low polymorphism and mutations as well as adaptive evolution in the CHS1 gene, accompanied by biochemistry and gene expression studies, should be done in these 20 species of Zingiberaceae, Costaceae, and Poaceae.

One of the studied CHS gene families is the CHS1 gene. CHS1 gene is known for its function in the flavonoid biosynthetic pathway. However, not many studies have been reported on the CHS1 gene in the Commelinids clade, especially the evolution of this gene within three families: Zingiberaceae, Costaceae, and Poaceae. Thus, this study aimed to perform a preliminary in silico comparative analysis of the CHS1 gene across these three families. Through this in silico comparative analysis, 20 partial sequences of the CHS1 gene, which are restricted to 565 bp regions, were analysed. The partial sequences were extracted from the National Center for Biotechnology Information database comprised of 16 Zingiberaceae species, three Costaceae species, and one Poaceae species. From the analysis, these targeted regions showed a low polymorphic site (18.23%) with 103 positions of single nucleotide polymorphisms and three mutations (substitution, insertion, and deletion). Meanwhile, phylogenetic analysis showed no clear evolutionary pattern within the three studied families. In conclusion, the studied partial sequences of the CHS1 gene in Zingiberaceae, Costaceae, and Poaceae showed that the gene is conserved within the Commelinids clade.

Pangasius catfish, Pangasius nasutus, is a promising candidate for aquaculture due to its high market value. However, the presence of pathogenic bacteria in Aeromonas hydrophila is a major concern in P. nasutus farming in this country. This study determines the pathogenicity of A. hydrophila in P. nasutus. A total of 80 P. nasutus juveniles were intraperitoneally injected with 0, 103, 105, and 107 CFU mL-1 of A. hydrophila and monitored until 240 hr. The infected moribund fish’s kidneys, livers, and spleens were collected for histopathological analysis. The LD50-240hr value was found at 0.8 × 104 CFU/ml of A. hydrophila. The percentage of mortality in 0, 103, 105, and 107 CFU/ml infected groups were found to be at 0, 40, 60, and 90%, respectively. The infected fish showed congestion at the base of the fin, ascites, enlarged gall bladder, and swollen spleen. It is the earliest report on A. hydrophila’s pathogenicity in high-value native fish, P. nasutus.
