ABSTRACT

Background and Aim: Theileriosis is a parasitic disease caused by the hemoprotozoan Theileria spp. The main transmission route of this disease is through tick vector bite. Theileriosis causes economic losses in livestock such as Bali cattle. This study aims to analyze the prevalence of theileriosis and its correlation with the hematological profile of Bali cattle from the subdistrict of Muara Bulian, Batang Hari, Jambi, Indonesia.

Materials and Methods: Ninety-four blood samples were collected through jugular vein of Bali cattle. The presence of Theileria spp. was determined using blood smear. Routine blood tests and double-staining immunohistochemistry against CD4+ and CD8+ lymphocytes were conducted on all blood samples.

Results: A total of 34.04% of the samples were infected by Theileria spp. Theileriosis affected only hemoglobin level (p<0.05); it did not affect the other parameters of the hematological profile (p>0.05). However, it also decreased CD4+ and CD4+/CD8+ ratio (p<0.05), besides increasing CD8+ (p<0.05).

Conclusion: Theileriosis does not change the hematological profile of Bali cattle except for the hemoglobin levels. Moreover, it promotes T-cell depletion.

Keywords: Bali cattle, CD4+/CD8+ ratio, correlation, hematological profile, prevalence, theileriosis.

ABSTRACT

Aim: This study aimed at optimizing γ-aminobutyric acid (GABA) production using lactic acid bacteria (LAB) of an Indonesian indigenous fermented buffalo milk (dadih) origin. This study utilized LAB previously cultured from dadih that has the ability to produce GABA.

Materials and Methods: The study started with the identification of selected LAB by 16S rRNA, followed by optimization of GABA production by culture conditions using different initial pH, temperature, glutamate concentration, incubation time, carbon, and nitrogen sources. 16S rRNA polymerase chain reaction and analysis by phylogenetic were used to identify Lactobacillus plantarum (coded as N5) responsible for the production of GABA.

Results: GABA production by high-performance liquid chromatography was highest at pH of 5.5, temperature of 36°C, glutamate concentration of 500 mM, and incubation time of 84 h. Peptone and glucose served as the nitrogen and carbon sources, respectively, whereas GABA was produced at optimum fermentation condition of 211.169 mM.

Conclusion: Production of GABA by L. plantarum N5 was influenced by initial pH of 5.5, glutamic acid concentration, nitrogen source, glucose as carbon source, and incubation temperature and time.

Keywords: fermented buffalo milk, Indonesian indigenous product, lactic acid bacteria, γ-aminobutyric acid.

ABSTRACT

Background and Aim: Coleus amboinicus (CA) plants are known to exert antibacterial and anti-inflammatory effects and demonstrate antiproliferative effects against cancer cells. This study aimed to investigate the activity of CA extract on the expression of transforming growth factor-1β (TGF-1β) in cisplatin-induced nephropathy in Wistar rats (Rattus norvegicus).

Materials and Methods: CA was obtained from fresh leaves of CA and was extracted using 96% ethanol maceration. This blinded, controlled, randomized post-test study assigned 24 Wistar rats to three groups (n=8). Negative controls received normal saline (P0), nephropathy was induced in rats by cisplatin (5 mg/kg, IP) (P1), and treated with ethanolic coleus extract (500 mg/kg, PO) (P2), respectively, for 7 days. Nephropathy was induced on the 4th day. All rats were sacrificed on the 8th day for blood and kidney sample collection. Concentrations of blood urea nitrogen (BUN), creatinine, and alkaline phosphatase were analyzed using colorimetric analysis. A semi-quantitative analysis was performed on sectioned kidneys to determine the numbers of positive cells for TGF-1β expression and to evaluate structural and functional alterations in the kidneys using histopathological and immunohistochemical staining.

Results: The concentrations of BUN, creatinine, and alkaline phosphatase from blood samples in the treatment group were significantly lower than those of the control group. Morphological evaluation of the tubular interstitium and glomeruli revealed that necrotic, degenerating, and infiltration of cells significantly decreased in the treatment group compared to the control group. The mean immunostaining scores indicating the presence of TGF-1β were 7.8 in the ethanolic coleus extract group, 3 in the induction group, and 2.3 in the control group. The expression scores for TGF-β1 were significantly different between the ethanolic coleus extract treatment and control group.

Conclusion: Our results suggest that in Wistar rats with cisplatin-induced nephropathy, CA extract inhibits pathological lesions by regulating the renal expression of TGF-1β in areas containing the renal tubules and glomeruli. 

Keywords: cisplatin, Coleus amboinicus, nephropathy, transforming growth factor-1β.

ABSTRACT

Background and Aim: Paramphistomiasis is common in tropical countries such as Indonesia and affects livestock and various endemic wild animals such as Sumatran elephants. However, the specific species of paramphistomoid worm that causes paramphistomiasis are rarely reported. The study aims at identifying paramphistomoid worm that infects Sumatran elephants.

Materials and Methods: Flukes were collected from the feces of five semi-captive Sumatran elephants that lived at Tegal Yoso Elephant Response Unit in Way Kambas National Park, in 2018, after treatment of oxyclozanide 1 g at the dose of approximately 5-8 mg/kg of body weight. Eight paramphistomoid worms were flattened and stained in Semichon's carmine for morphological identification, and five other worms were used for molecular identification at second internal transcribed spacer (ITS-2) of ribosomal deoxyribonucleic acid sequence.

Results: Forty-five flukes were collected from five Sumatran elephants in Lampung, Indonesia. Eight paramphistomoid worms were morphologically identified as Pfenderius heterocaeca> and five isolates did not show any variation in ITS-2. Phylogenetic analysis showed that there was a close genetic relationship between our sample and Chiorchis fabaceus that had a family similar to the samples.

Conclusion: Based on the morphological and molecular characteristics, the paramphistomoids found in Sumatran elephant on Way Kambas National Park are P. heterocaeca.

Keywords: internal transcribed spacer-2, paramphistomiasis, Pfenderius spp., Sumatran elephant.

ABSTRACT

Aim: The aim of this research was to study the effect of rabbit hemorrhagic disease virus (RHDV) on the host immune response by examining the cellular composition/pathology of lymphoid organs and serum levels of tumor necrosis factor-alpha (TNF-α) and interferon-gamma (IFN-γ).

Materials and Methods: Nine adult rabbits were inoculated with 1 ml of 10% infected liver homogenate, and three rabbits served as controls. The rabbit hemorrhagic disease (RHD)-induced animals were studied on 3 consecutive days post-infection. Diagnosis of RHD was made through routine hemagglutination tests and the polymerase chain reaction. Blood smears and tissue samples from bone marrow (BM), spleen, lymph nodes, and liver were analyzed for cell composition and cytopathology. Serum levels of TNF-α and IFN-γ were measured by enzyme-linked immunosorbent assay.

Results: RHD showed a decreased absolute cell count of blood as well as lymph nodes, spleen, and BM cell populations with marked left shift. This was seen as a progressive rise in immature and blast cells. Quantitative cellular changes were accompanied by an increase in specific inflammatory cytokines. Immunocytopathological alterations were evidenced by: Vacuolized, hyperactivated tissue macrophages, finding of Dohle bodies in neutrophils, and activated lymphocytes with increased nuclear-cytoplasmic ratio. Cytoplasmic eosinophilic viral inclusions found in tissue (liver, spleen, and BM) macrophages were shown for the 1st time in RHD. Megakaryocytic emperipolesis was a common feature of RHD.

Conclusion: These studies suggest that RHDV induces pathology in leukocytes due to hyperactivation with left shift (toward immature stages of the different cell lineages). Macrophages are increased in number and show an expressed cytopathic effect often accompanied by viral eosinophilic cytoplasmic inclusions. They also developed a secretory activation (increased levels of pro-inflammatory cytokines).

Keywords: cytopathology, emperipolesis, eosinophilic viral inclusions, immune response, macrophages, rabbit hemorrhagic disease virus.

ABSTRACT

Aim: This study aimed to determine the genetic and non-genetic factors affecting pre-weaning body weight (BW) and morphometry in Assam Hill goat along with the genetic parameters.

Materials and Methods: The detailed information in respect of BW and body measurements of 960 animals at birth and 3 months of age belonging to three different populations of Assam Hill goat maintained at field units, namely, Batabari, Nahira, and Tetelia under "All India Coordinated Research Project on Goat Improvement" were utilized in the present study. The data were analyzed using least squares technique.

Results: The least squares means for BW, height at withers (HW), heart girth (HG), and body length (BL) were 1.166±0.008 kg, 26.198±0.070 cm, 26.695±0.096 cm, and 29.482±0.119 cm at birth and 4.590±0.083 kg, 36.850±0.105 cm, 40.741±0.115 cm, and 39.703±0.108 cm at 3 months of age, respectively. Location had a significant effect on BW, HW, and BL at both birth and 3 months and on HG at 3 months of age. Season of birth exerted significant effect only on BL at birth, whereas the significant effect of sex was observed on HG and BL at 3 months of age. The heritability estimates for BW and body measurements were moderate indicating the scope of selection. The phenotypic and genetic correlations among BWs and body measurements at birth and 3 months of age were positive in direction and high in magnitude.

Conclusion: On the basis of the present findings, it could be concluded that the weaning weight of kids can be considered for the selection of parent stock to increase productivity and eventually the economic efficiency. Further, animals with higher body measurements at initial phases of growth will perform better with respect to even BW at later stages of growth.

ABSTRACT

Background and Aim: Ivermectin (IVM) has been used in veterinary practice to control different parasitic infestations over the past two decades. This study aimed to re-assess the acaricidal effects of IVM, as well as to evaluate its efficacy against Rhipicephalus (Boophilus) annulatus by determining the mortality rate, γ-aminobutyric acid (GABA) level, and oxidative/ antioxidative homeostasis (malondialdehyde [MDA] levels and glutathione S-transferase [GST] activities).

Materials and Methods: Adult females of Rhipicephalus (Boophilus) annulatus were picked from cattle farms in El-Beheira Governorate, Egypt. Ticks were equally allocated to seven experimental groups to assess the acaricidal potential of IVM chemotherapeutics in controlling R. (B.) annulatus. IVM was prepared at three concentrations (11.43, 17.14, and 34.28 μM of IVM).

Results: Mortality rate was calculated among the treated ticks. In addition, GABA, GST, and MDA biomarker levels were monitored. The data revealed a noticeable change in GST activity, a detoxification enzyme found in R. (B.) annulatus, through a critical elevation in mortality percentage.

Conclusion: IVM-induced potent acaricidal effects against R. (B.) annulatus by repressing GST activity for the initial 24 h after treatment. Collectively, this paper reports the efficacy of IVM in a field population of R. (B.) annulatus in Egypt.
