Abstract

Several pre-analytical variables influence hematological results, including anticoagulant use, storage temperature, and time between blood sample collection and analysis. Delayed sample analysis owing to prolonged storage could result in erythrogram profiles, which could complicate the interpretation of the resulting data. This study investigated the erythrogram profile of tripotassium ethylenediaminetetraacetic acid (K3EDTA) in blood samples stored for 48 h at 4°C. Ten healthy blood samples of Ongole crossbred cattle were collected into K3EDTA tubes from the jugular or coccygeal veins and analyzed for erythrogram profiles (erythrocyte counts, hemoglobin levels, hematocrit value, and erythrocyte morphology). Blood sample analysis for the control (0 h) was performed within ± 1.5 hours after collection, then the samples were refrigerated (4°C) and analyzed at 3, 6, 9, 12, 24, and 48 h. The results showed increased (p < 0.05) erythrocyte counts and hematocrit values after 9–24 and 6–48 h of storage, respectively. There was a significant difference in erythrocyte diameter between 0 h and other time observations (p < 0.05). Echinocytes were observed at 0 h of storage and continued to increase up to 48 h. Hypochromasia was also found at 6 to 48 hours of storage. Therefore, the analysis of blood samples for erythrogram parameters should be performed as soon as possible, preferably within three hours after collection, to ensure clinically reliable results.

Abstract

This study investigated the prevalence of Aspergillus sp. in tilapia sold for consumption at Pasarean Village in Bogor District. A total of 50 fish were sampled for further investigation. The clinical signs of fish were eroded fins, gills, haemorrhages, and wounds. The presence of pathogenic fungi was confirmed through fungal isolation from the skin, gills, and cloaca and subsequent culturing on potato dextrose agar. Macroscopic and microscopic observations determined Aspergillus sp. The results showed that four Aspergillus species were identified i.e., A. terreus (2%), A. flavus (4%), A. fumigatus (42%), and A. niger (4%), with the occurrence of co-infection between A. fumigatus and A. flavus (2%); A. fumigatus and A. terreus (2%); and between A. fumigatus, A. flavus, and A. niger (2%) reported a total prevalence of 58%. Further study is necessary to mitigate the crucial impact of fungal diseases in aquaculture systems, leading to effective prevention and control strategies, thus ensuring the safety and sustainability of aquaculture practices in Indonesia.

Abstract

Barred loach Nemacheilus fasciatus are unable to reproduce naturally in captivity due to the lack of environmental cues and gonadal maturation occurs slower than in the wild. To optimize breeding procedures for this fish species, we determined whether hormone application via the gills was an effective process and assessed hormone dosage treatments. Oodevâ„¢ was used to induce gonadal maturation and Ovaprimâ„¢ was used to induce spawning via a topical gill approach. Multiple maturation parameters such as gonadal-somatic index (GSI) and hepatosomatic index (HSI), fecundity, and egg diameter; and spawning parameters such as latency period, egg produce, fertilization rate (FR), hatching rate (HR), survival rate (SR) were recorded and compared between the hormone dosage treatments and control treatment. Both the Oodevâ„¢ gonadal maturation induction and Ovaprimâ„¢ spawning induction were effectively applied to barred loach via topical gill application. Gonadal maturation parameters were positively correlated with dosage and all were significantly different. Fry survival rate was not different between doses. The optimal dose of Oodevâ„¢ (0.75 µL/g fish) resulted in male GSI of 5.334 ± 0.320%, female GSI of 15.501 ± 0.675%, male HSI of 0.416 ± 0.023%, female HSI of 1.670 ± 0.104%, egg fecundity 4584.20 ± 493.216 eggs, egg diameter 0.964 ± 0.0151 mm. Ovaprimâ„¢ optimal dosage (3.00 µL/g female and 1.50 µL/g male) was resulted latency period 11.05 ± 0.52 hours, egg produced 3504.83 ± 358.57, FR 96.77 ± 0.88%, HR 83.62 ± 3.78%, and SR 91.44 ± 2.53%.

Abstract

The phenomenon of sexual dimorphism in climbing perch, which shows that female fish grow faster than males, underlies the development of mono-sex culture. Female mono-sex culture is more applicable for farmers by crossing neo-male fish with normal females. The timing of sexual differentiation in climbing perch is still unknown. It is very useful in sex reversal procedures to produce neo-male climbing perch. This study revealed the time and status of climbing perch sexual differentiation. Ten samples of climbing perch from the spawning of five pairs of parents were taken from the nursery pond at 10–29 days post-hatching (dph). Samples were prepared through a histology preparation procedure. Observations of the structure and characteristics of the gonads were carried out using a light microscope and analyzed histologically. The results indicated that gonad samples aged 10, 11, 12, 13, 15, and 16 dph showed primordial germ cells surrounded by somatic tissue forming genital ridges and mitotic division. Meanwhile, the gonads begin to differentiate as ovaries found at 18 dph with the presence of oogonia and ovarian cavities. Gonads aged 20–21 dph increasingly showed single oogonia cells (size 20–37.5 µm), germ cell cysts, genital ridges, oocytes undergoing the vitellogenesis process, perinucleolar oocytes, and the formation of the ovarian cavity. Sex differentiation of climbing perch was predicted from 18–21 dph. This conclusion underlies that the sex reversal procedure in climbing perch must be carried out before 18 dph.

Abstract

Curcuma zedoaria Rosc (Zingiberaceae), known as white turmeric or temu putih, is commonly used as traditional medicine in Indonesia. The toxicity of this herb needs to be studied to improve its application. This study aimed to evaluate the toxicity of the crude ethanol extract of temu putih rhizome against brine shrimp (Artemia salina) larvae and zebrafish (Danio rerio) embryos and to analyze the potential active compounds contained in the extract. The crude ethanol extract showed a 50% lethal concentration value (LC50) at 588 ppm against brine shrimp larvae and 224 ppm against zebrafish embryos. Based on the gas chromatography-mass spectrometry analysis, the suspected active compounds that play a role in the toxicity were epicurzerenone, curzerene, and curzerenone, while 2,4,6-trimethylacetophenone was the predominant compound.

Abstract

The high demand for fish consumption has an impact on increasing aquaculture productivity and causes the vulnerability of increasing bacterial populations in aquaculture fields, so more rapid handling is needed. The use of phenotypic KIT methods (API 20E) has been applied as a targeted and efficient identification support in targeting better bacterial identification accuracy but often provides unequal results. Method validation is one of the general requirements for the competence of a laboratory evaluation: to provide coherent, interpretable, and accurate results with known uncertainties. The purpose of this study was to validate the API 20E KIT method for the identification of A. hydrophila. The conventional method used as a reference is SNI 7303.1:2015. The validation parameters consisted of determining the limit of detection, sensitivity, and specificity tests, as well as the positive predictive value and negative predictive value. The results showed that the limit of the detection value of the API 20E KIT was at a concentration of 100 CFU/mL with an ID of 99.00%. The sensitivity and specificity values in the positive and negative target samples were 100% with a positive predictive value and a negative predictive value of 0%, respectively. In conclusion, the API 20E KIT method as an alternative test method or rapid test was proven valid for identifying A. hydrophila by the test results using the reference method.

Abstract

The effect of Gum Arabic (GA) on growth, carcass quality, blood parameters, gut morphometry, and organ histology of African catfish Clarias gariepinus was studied. Five isonitrogenous diets with inclusion levels of GA at 0 g/100 g (GA0; control), 5 g/100 g (GA5), 10 g/100 g (GA10), 15 g/100 g (GA15), and 20 g/100 g (GA20) were formulated in a 40% crude protein diet. Juveniles of C. gariepinus with average weight (7.35±0.48 g/fish) were stocked at 13 fish/25 L of water for 12 weeks in a completely randomized design and fed at 3% body weight daily. Growth indices showed GA10 improved the mean weight gain (69.88±8.89 g) and specific growth rate (2.76±0.14 %/day) while at (GA15); (GA20) growth was depressed. Carcass quality revealed dietary levels were superior to control with GA10 significantly different (p < 0.05) amongst treatments in protein and fat content. Hematological profile showed variations; erythrocyte indices compared to control, while plasma chemistry of aspartate aminotransferase, alkaline phosphatase, and alanine aminotransferase showed no difference (p > 0.05). Gut morphometrics varied with no particular pattern. At inclusion above GA5 the gill, liver, and kidney were affected histologically with no changes in the intestines of all treatments. Diet supplemented with gum arabic at 10 g/100 g improved indices of performance of C. gariepinus juveniles in this study.

Abstract

The impact of supplementing glucose, glycine, or a combination of both in Ringer's lactate egg yolk base extender to preserve the quality of semen from local Indonesian chickens has not been previously investigated. This study aimed to examine the potential of glucose and glycine on chicken semen stored at 5°C for 120 hours. In this study, five local roosters were used. The parameters under observation included semen volume, odor, pH levels, consistency, color, mass movement, concentration, motility, viability, abnormality, plasma membrane integrity, chromatin degeneration, and acrosomal cap integrity. This study was conducted using a completely randomized design (CRD) with four treatments groups and 10 replication, i.e. T1 (control without supplementation), T2 (50 mM glucose), T3 (60 mM glycine), and T4 (a combination of 50 mM glucose and 60 mM glycine), respectively. In result, semen volume was 0.54 ± 0.17 mL/ejaculate, a milky white color, distinctive odor, thick consistency, good mass movement (++/+++), pH of 7.37 ± 0.23, motility of 91.50 ± 2.42%, plasma membrane integrity of 96.85 ± 0.96%, abnormality at 2.88 ± 0.77%, the concentration of 3.04 ± 0.3 billion/mL, and viability of 96.47 ± 1.71%. Following storage at 5°C for 120 hours, the motility, viability, abnormality, and acrosomal cap integrity of local chicken spermatozoa significantly different (p < 0.05) between T3 and T4 compared to T1 and T2 groups. Moreover, the integrity of the plasma membrane and chromatin degeneration in treatment T3 significantly different (p < 0.05) from T1, T2, and T4 groups. In conclusion, local chickens exhibited fair quality fresh semen both in macroscopic and microscopic evaluations. Furthermore, the combination of 60 mM glycine and 50 mM glucose into local chicken semen stored at 5°C for 120 hours effectively preserved motility and viability, minimized abnormality, maintained plasma membrane integrity, minimized chromatin degeneration, and retained acrosomal integrity.

Abstract

Vero cell culture as a platform for producing viral vaccines is an established and standardized process in vaccine manufacture. Generally, Vero cell culture requires media as a source of nutrition with serum supplementation to provide growth factors. However, the serum has several disadvantages including batch to batch variation and adventitious agent. Therefore, chemically defined serum-free media (SFM) are formulated by using standardized growth factors. Epidermal Growth Factor (EGF) is one of growth factors that showed adequate mitogenic support in serum-free medium system, especially in Vero cells. In this study, SFM-EGF media was compared with serum supplementation media, namely MEM 10% and MEM 5% FBS supplementation. The cell morphology was observed using an inverted microscope and their proliferation was evaluated using a MTT colorimetric-based assay. Vero E6 and Vero CCL-81 cells morphology did not show any morphological changes. Vero E6 and Vero CCL-81 proliferation in SFM-EGF media on day one to four did not show a significant difference compared to MEM 10% or MEM 5% serum supplementation media. However, the OD values of both Vero E6 and Vero CCL-81 cells given SFM-EGF media produced an average value below MEM 10% but higher than MEM 5% FBS supplementation. As such, this study proved that utilizing SFM-EGF could support the proliferation of Vero E6 and Vero CCL-81 cells.

Abstract

Striped snakehead fingerlings Channa striata reared in a concrete pond with size 13.5 m3 (3 m ´ 3 m ´ 1.5 m) in a hatchery farm, in Labu, Negeri Sembilan, Malaysia had more than 70% mortality. The pond contained 1500 fingerlings of 5–7 cm in total length (TL). The purpose of this study was to investigate the high mortality event on the farm as part of a veterinary diagnostics service. Clinical signs observed were skin discoloration, lethargy, and anorexia. Necropsy was performed in 10 fish with gross lesions of 1–2 mm and multiple whitish nodules in the abdominal organs and most notably in the liver, and kidney. Following necropsy, bacteriology samples from the kidney and liver were inoculated onto Tryptic Soy Agar (TSA) and Blood Agar (BA). Pure colonies were observed and were Gram-negative with short rod morphology. The full-length 16S rRNA gene was amplified from the pure colonies followed by sequencing using the Nanopore MinIONâ„¢ (Oxford Nanopore, UK). The isolated strain was identified as Aeromonas schubertii based on the assembled 16S rRNA sequence showing nucleotide identity of 99.73% (top hit) to A. schubertii (GenBank Accession: NR_037014.2) while only a nucleotide identity of 97.55% was observed against Aeromonas hydrophila (GenBank Accession: NR_119190.1-), respectively. Histopathological examination from the liver, kidney, spleen, and intestine revealed granulomatous nephritis, and degeneration of tubular epithelium, with granulomatous hepatitis, splenitis, and enteritis. The prognosis of this case was grave. No treatment was given as the owner had decided to dispose of all current stock. This is the first A. schubertii infection in C. striata described in Malaysia. The findings of the present study may serve as a reference for similar cases in C. striata in the future so rapid diagnosis and treatment can be made if required.
