Bee venom with an antimicrobial effect is a powerful natural product. One of the most important areas where new antimicrobials are needed is in the prevention and control of multi-drug resistant pathogens. Today, antibacterial products used to treat multi-drug resistant pathogen infections in hospitals and healthcare facilities are insufficient to prevent colonisation and spread, and new products are needed. The aim of the study is to investigate the antibacterial effect of the bee venom (BV), a natural substance, on the species of Methicillin resistant Staphylococcus aureus, Vancomycin resistant Enterococcus faecalis, Carbapenem resistant Escherichia coli, Carbapenem resistant Klebsiella pneumoniae and Carbapenem resistant Acinetobacter baumannii. As a result of this study, it was found that MIC90 and MBC90 values ranged from 6.25 μg/mL – 12.5 μg/mL and numbers of bacteria decreased by 4–6 logs within 1–24 h for multi-drug resistant pathogens. In particular, Vancomycin resistant Enterococcus faecalis isolate decreased 6 log cfu/mL at 50 μg/mL and 100 μg/mL concentrations in the first hour. The effective bacterial inhibition rate of bee venom suggests that it could be a potential antibacterial agent for multi-drug resistant pathogens.Contribution: The treatment options of antibiotic-resistant pathogens are a major problem in both veterinary and human medicine fields. We have detected a high antibacterial effect against these agents in this bee venom study, which is a natural product. Apitherapy is a fashionable treatment method all over the world and is used in many areas of health. Bee venom is also a product that can be used as a drug or disinfectant raw material and can fill the natural product gap that can be used against resistant bacteria.

Objectives: This study aimed to examine the impacts of the wide range of concentrations of glucose and trehalose on the tris-citric acid-egg yolk-fructose (TCEF) extenders for cryopreservation of goat semen. Materials and Methods: The sperm sample was pooled, washed, and diluted in control (TCEF without glucose and trehalose), TCEF + glucose (75, 150, 450, and 900 mm), and TCEF + trehalose (75, 150, 450, and 900 mm). After equilibrations, the semen straws were frozen under LN2 in the LN2 tank. After LN2 storage, the straws were thawed at 37°C for 30 seconds. The sperm parameters of all study groups were checked after equilibration and freezing. Results: After equilibration, the progressive motility (PM), total motility (TM), and viability of sperm in G-75, G-150, G-450, T-75, T-150, and T-450 were not significantly different (p < 0.05) from those in control. After cryopreservation and thawing, the PM, TM, and plasma membrane integrity (PMI) of T-150 were significantly higher (p < 0.05) than in control, G-75, G-900, T-75, and T-900. The viability of sperm in T-150 was substantially higher (p < 0.05) than in the control, whereas there was no significant difference among the control, G-75, G-900, T-75, and T-900. However, the acrosome integrity (AI) of sperm in G-900 was significantly decreased (p < 0.05) compared to the control, G-75, G-150, G-450, T-75, T-150, and T-450. Conclusion: According to the findings, the supplementation of 150 mm trehalose in the TCEF diluent was more efficient for sperm cryopreservation in the buck as reflected by PM, TM, viability, PMI, and AI.

Objective: This study aimed to validate the analytical precision of the Accutrend® Plus portable electronic equipment (PE) to determine glucose (GLU), total cholesterol (TC), and triglycerides (TG) in rats and dogs using the conventional laboratory method (CM) as a reference. Materials and Methods: To determine the analytical accuracy of the Accutrend® Plus in the measurement of GLU, CT, and TG. The EP-9-A2 guide (Clinical and Laboratory Standards Institute), Bland-Altman graphical analysis, and Lin’s correlation coefficient of concordance (CCC) were implemented. Results: The average differences (p > 0.05) between PE and CM for GLU, TC, and TG were 2.21, 1.20, and 0.72 mg·dl−1, respectively, in rats and 1.06, 4.30, and 2.41 mg·dl−1, respectively, in dogs (p > 0.05). Both methods showed a linear relationship with Pearson’s correlation coefficients > 0.96 and R2 > 0.97 for the three biochemical indicators evaluated in both species. The GLU, TC, and TG values obtained by the PE were substantial, as evident from Lin’s CCC > 0.96. Conclusion: The PE Accutrend® Plus is potent for monitoring GLU, TC, and TG in rats and dogs because of its precision and ability to facilitate measurement by reducing stress in animals during sampling.

Objective: This study aimed to examine the diversity of phenotypic characteristics of female Alabio ducks (Anas platyrhynchos Borneo) and their eggs in South Kalimantan, Indonesia. Materials and Methods: A total of 200 18-month-old ducks and 300 eggs were selected using a survey method with multistage random sampling. These samples were obtained from two districts in the province of South Kalimantan [Banjar (BJ) districts and Tanah Laut (TL)]. The observed data were analyzed descriptively with variations using the independent t-test for each location. Principal component analysis (PCA) was deployed to assess the overall variance and define variables with greater discriminatory power between individuals. Results: The observations on the body’s physical characteristics and the eggs of Alabio ducks showed significant differences between ducks from BJ and TL areas (p < 0.05) except for yolk diameter, albumen height, albumen index, and Haugh unit (HU) (p > 0.05). Most egg quality traits from BJ were greater than those from TL, which include egg weight, egg length, egg width, yolk weight, albumen weight, shell weight, shell thickness, and egg shape index. The PCA revealed medium-to high communalities in the phenotypic body characteristics of Alabio ducks and their eggs. Conclusion: Significant physical characteristics and egg quality differences were found between the two locations, except for the albumen index and HU, with substantial variability within each trait. These traits could explain the total variation in the phenotypic characteristics of female Alabio ducks.  J. Adv. Vet. Anim. Res., 10(2): 249–256, June 2023 http://doi.org/10.5455/javar.2023.j676

Objective: The feeding effects of DoLa (a combination of Dayak onion extract and probiotic Lactobacillus acidophilus) on hematological indices and lymphoid organs as indicators of broiler health status were evaluated in the present study. Materials and Methods: 192 1-day-old unsexed broilers of the CP 707 strain with a body weight of 46.43 ± 1.65 gm were randomly divided into 4 dietary treatments with 6 replications. The dietary treatments applied were basal diet (BD) as a control with a code of DoLa0, BD + 0.1% DoLa (DoLa1), BD + 0.2% DoLa (DoLa2), and BD + 0.3% DoLa (DoLa3). The parameters monitored included hemoglobin (Hb), red blood cell (RBC), heterophile (H), lymphocyte (L), white blood cell (WBC), heterophile-lymphocyte (H/L) ratio, the lymphoid organs (bursa Fabricius,spleen, and thymus) relative weight, as well as carcass weight. Results: The results indicated a significant improvement in WBC, L, and carcass weight (p < 0.05) as the feeding level of DoLa increased while the H and H/L ratio decreased. However, the dietary inclusion of DoLa did not affect the lymphoid organs’ relative weight, RBC, and Hb concentrations. Conclusion: The mixture at 0.3% significantly improved health status through the indicators of hematological indices, lymphoid organs, and carcass weight of broilers.  J. Adv. Vet. Anim.

Objective: Camel mastitis is indeed a serious problem that can have significant impacts on animal health and production as well as pose a potential public health hazard. This work aimed to identify the bacterial species responsible for camel mastitis and evaluate the associated immunological and clinicopathological alterations in infected camels. Materials and Methods: Raw milk and blood samples were collected from 40 apparently healthy she-camels, and 40 she-camels suffered from clinical mastitis (CMG). Milk samples were subjected to bacteriological examination. Serum immunological, biochemical, and hematological parameters were estimated and statistically analyzed. Results: Similar bacterial species were obtained from the two groups with different isolation rates. Staphylococcus epidermidis and Escherichia coli were the dominant species in the apparently healthy group, while Pseudomonas aeruginosa and Bacillus cereus were the dominant species in CMG. A significant (p < 0.05) elevation of the pro-inflammatory cytokines, acute phase proteins (APPs), free radicals, total protein, Glob, kidney and liver function tests, and triglyceride concentrations were detected in CMG, and a significant (p < 0.05) decrease in the anti-inflammatory cytokine, antioxidants, Alb, glucose, and T/LDL/HDL-cholesterol concentrations was observed in CMG. Microcytic hypochromic anemia with hypoferremia, hypotransferrinemia, hyperferritinemia, and neutrophilic leukocytosis was depicted in CMG. The estimated pro-inflammatory cytokines, APPs, and total antioxidant capacity (TAC) yielded high sensitivity and specificity, but the highest likelihood ratio wasfor TAC, fibrinogen (Fb), and ferritin, and the highest percentages of increase were for IL-1α and IL-1β. Conclusion: The study emphasizes the importance of hygienic preventive measures to control camel mastitis and the importance of supportive treatment to reverse the hemato-biochemical and iron profile changes that result from the immune response in mastitic she-camels. TAC, Fb, ferritin, IL-1α, and IL-1β are good biomarkers for camel mastitis. J. Adv. Vet. Anim. Res., 10(2): 284–291, July 2023 http://doi.org/10.5455/javar.2023.j680

Objective: This research investigated secoisolariciresinol diglucoside (SDG) flax extract effects on apoptosis, hedgehog (Hh), autophagy, and the anti-oxidation process in experimentally induced obesity. Materials and Methods: Forty rats were separated into two sets regarding either receiving a normal balanced diet or a high-fat diet (HFD) and then distributed into four groups: GI: The control group had a regular diet for 12 weeks. GII: animals received a high-fat meal and saline by gastric gavage. GIII: HFD obese rats treated with SDG extract orally (10 mg/kg/b.w.) and 1.18 mg SDG/kg in the diet for 4 weeks GIV: Normal balanced diet rats received SDG extract orally (10 mg/kg/b.w.) and 1.18 mg SDG/kg of chow for 12 weeks in addition to their regular balanced diet. Results: The administration of SDG extract exhibited a significant drop in body weight, glucose, lipid profile, and leptin compared to the obese group. It also improved the antioxidant levels (lowering the levels of malondialdehyde while increasing the total antioxidant capacity) and anti-inflammatory status (decreasing interleukin-6 and tumor necrosis factor-alpha). SDG extract downregulates the expression of HH genes (protein patched homolog 1, Hh-interacting protein, glioma-associated oncogene homolog 1, and smoothened receptor) in conjunction with the modulation of autophagy genes and apoptotic proteins. Conclusion: SDG extract showed improved anti-inflammatory and antioxidant status and downregulated the expression of HH genes while modulating autophagy genes and apoptotic proteins among obese rats, suggesting that it may be used to avert and manage obesity and its correlated complications by modulating oxidation, inflammation, autophagy, and apoptosis. Advanced future research on the SDG autophagy pathway to address obesity and its complications is mandatory. J. Adv. Vet. Anim. Res., 10(2): 321–335, June 2023 http://doi.org/10.5455/javar.2023.j684

Objective: This study examines the effect of fermented milk containing the probiotic Pediococcus acidilactici BK01 on cholesterol and intestinal microbiota. Materials and Methods: 24 male rats weighing an average of 200 gm each spent 1 week in a cage adapting to their new environment. They were fed standard feed daily and were allowed to drink ad libitum. For 3 weeks, rats were divided into four groups (doses of fermented milk): M+ (control), M1 (0.35 ml), M2 (0.70 ml), and M3 (1.05 ml). The analysis includes bodyweight determination, serum biochemical analysis, and intestine microbiota analysis. Results: The results indicated that while P. acidilactici BK01 fermented milk did not affect body weight or high-density lipoprotein, it did have a beneficial effect on total serum cholesterol and triglyceride levels. Additionally, treatment of fermented milk with P. acidilactici BK01 has been shown to increase the total lactic acid bacteria (LAB) in the intestine, as indicated by changes in the intestinal villi. Conclusion: Administering fermented milk (P. acidilactici BK01, 1.05 ml) can reduce total serum cholesterol and increase the number of LAB in intestinal villi in experimental animals, so it has the potential to be a probiotic.
