Abstract

Background: Elevated temperature can disrupt embryonic development in ectothermic vertebrates by altering developmental progression, growth, and morphological integrity. Lycopene is a naturally occurring carotenoid with recognized antioxidant properties and may contribute to cellular protection under stressful conditions. Purpose: This study evaluated the effects of lycopene supplementation on developmental progression, larval body length, and morphological abnormalities in zebrafish (Danio rerio) exposed to acute heat stress. Method: A total of 240 viable zebrafish embryos were assigned to non heat stress (NHS; 28°C) or heat stress (HS; 30°C for 1 h) conditions. Each thermal condition comprised three treatments: control without lycopene (P1), 2 µL lycopene supplementation (P2), and 4 µL lycopene supplementation (P3), with four replicates per treatment. Embryonic development was monitored until 96 h post fertilization (hpf). Larval body length was measured using ImageJ, while morphological abnormalities were assessed microscopically. Body length data were analyzed using one-way ANOVA followed by the LSD post hoc test (p < 0.05). Results: Heat stressed larvae generally exhibited shorter body lengths than non heat stressed larvae, with significant overall differences among treatment groups (p < 0.05). Within the heat stressed groups, mean body length increased numerically from 3.10 mm in HSP1 to 3.28 mm in HSP2 and 3.30 mm in HSP3. Morphological abnormalities occurred in 12.5%, 5.0%, and 2.5% of HSP1, HSP2, and HSP3 embryos or larvae, respectively, and predominantly involved axial or vertebral alterations, spinal curvature, and failure to hatch. Conclusion: Acute heat exposure was associated with impaired zebrafish development. Lycopene supplementation was associated with numerically greater body length and a lower descriptive frequency of morphological abnormalities under heat stress conditions, supporting its potential mitigating effect on heat associated developmental impairment.

Abstract

Background: Trichodina spp. are common ectoparasites of cultured fish and are associated with impaired health and productivity. Purpose: This study examined the prevalence, organ distribution, and host related factors associated with Trichodina infestation in farmed Clarias gariepinus. Method: Ninety five farmed C. gariepinus were randomly sampled from concrete, earthen, and plastic tank production systems. Gill, skin, and fin scrapings were examined for Trichodina infestation using wet mount preparations. Sex, total length, body weight, and Fulton’s condition factor were also assessed. Parasites were identified using standard parasitological techniques. Associations between infestation status and categorical variables were evaluated using chi-square tests. Differences in Fulton’s condition factor between infested and non infested fish were assessed using an independent samples t-test. Statistical significance was established at p < 0.05. Results: The overall prevalence of Trichodina infestation was 42.1% (40/95). The gills were the most frequently affected site (67.5%), followed by the skin (40.0%) and fins (12.5%). Sex was not significantly associated with infestation (χ² = 0.24, df = 1, p = 0.62). However, significant associations were observed between infestation and total length (χ² = 11.02, df = 4, p = 0.026) and body weight (χ² = 13.67, df = 6, p = 0.033), with higher prevalence in intermediate to larger sized classes. Infested fish had significantly lower Fulton’s condition factor compared with non infested fish (t = 2.31, df = 93, p = 0.023). Conclusion: Findings from this farm level investigation demonstrate an association between Trichodina infestation, organ specific distribution, host size, and Fulton’s condition factor in farmed African catfish under routine aquaculture conditions. Routine parasitological surveillance, improved farm management practices may therefore be important for reducing parasite burdens, promoting fish health and productivity.

Abstract

Background: Newcastle disease virus (NDV), also known as avian paramyxovirus 1, is a viral disease that affecs domestic poultry and wild birds. NDV remains one of the most significant and widespread infectious diseases that can cause severe economic losses in poultry, including chickens and ducks. Purpose: Molecular characterization of the matrix protein (M) gene was performed to characterize NDV isolates obtained from unvaccinated ducks in Indonesia, determine their phylogenetic relationships, and predict potential B-cell epitopes relevant for vaccine development. Method: One hundred NDV samples were collected from unvaccinated ducks in West Sumatra and East Java, Indonesia. Viral RNA was extracted, and NDV was detected by reverse transcription polymerase chain reaction (RT-PCR) using three primer sets targeting the M gene. Sequence analysis was conducted using MEGA X software to identify mutations and construct phylogenetic trees. Linear B-cell epitopes and immunological parameters were predicted using the Immune Epitope Database (IEDB). Results: Among the 100 samples examined, 96 tested negative for NDV, whereas four samples were confirmed positive. Phylogenetic analysis revealed that three isolates clustered within genotype VII, while the majority belonged to genotype VI. Detailed characterization of the M gene revealed the genetic features of NDV circulating in ducks in Indonesia. Notably, the peptide TVDKRGRKVTFDKLERKI derived from the M protein was identified as a promising candidate for peptide based vaccine development against NDV. Conclusion: Evidence from molecular and phylogenetic analyses confirms the circulation of NDV among ducks in West Sumatra and East Java, Indonesia. Candidate peptide derived from the M protein was identified as a potential component of a peptide based vaccine against NDV; however, further in vitro and in vivo investigations are required to validate its immunogenicity and protective potential.

Abstract

Background: Brucellosis, a zoonotic disease caused by bacteria of the genus Brucella, affects multiple animal species worldwide. Timely detection and control depend critically on rapid diagnostic tests. Purpose: This study evaluated the diagnostic performance of two rapid lateral flow tests based on similar principles but employing different conjugates (protein A colloidal gold and protein G colloidal gold) for detecting antibodies against Brucella spp. in various animal species. Method: Across laboratory and field conditions in Cuba, 1,394 blood and serum samples from cattle, swine, sheep, and buffalo were analyzed. As the reference standard, complement fixation reaction (CFR) served as the benchmark. The calculated parameters included sensitivity, specificity, predictive values, Kappa index, and chi-square statistics. Results: Adequate diagnostic performance, with values exceeding 90% in most cases. The protein G colloidal gold conjugate exhibited superior overall performance: sensitivity of 98.1% (95% CI: 96.8–99.0%), specificity of 94.5% (95% CI: 92.8–95.9%), and Kappa index of 0.95 (95% CI: 0.93–0.97), denoting very good agreement with CFR. For cattle under field conditions, protein G achieved 100% sensitivity (95% CI: 98.3–100%), whereas protein A yielded 95.7% (95% CI: 92.1–97.9%). Lower specificity (84.4–85.0%) was recorded in swine, possibly attributable to Brucella suis circulation and the use of B. abortus antigen. Statistically significant associations between rapid tests and CFR across all species evaluated (p < 0.001) were confirmed by chi-square analysis. Conclusion: Both rapid tests, particularly the colloidal gold protein G conjugate, are reliable and practical tools for diagnosing brucellosis in multiple animal species. Implementing these tests could strengthen surveillance and control programs in Cuba, contributing to the One Health approach.

Abstract

Background: Orchitis is an inflammatory condition of the testicular tissue that may result from bacterial infection, trauma, or immune mediated processes and is characterized by swelling, pain, and structural alterations of the testes. Reports of orchitis in small rodents, including pet hamsters, are limited, and diagnostic approaches can be challenging because of their small size. Early and accurate diagnosis is essential to prevent progressive tissue damage and potential impairment of reproductive function. Purpose: Orchitis in hamsters is rarely reported; this case report aims to describe the clinical presentation and cytological findings of orchitis in a hamster and to highlight the diagnostic value of cytology in clinical practice. Case (s): Male hamster presenting with testicular swelling accompanied by purulent discharge. Clinical examination revealed enlargement of the testicular region and signs of inflammation, indicating a suspected inflammatory condition affecting the reproductive organ. Case Management: Fine needle aspiration (FNA) was performed, and cytological samples were stained using the Romanowsky method. Tn. Conclusion: Cytology revealed a predominance of degenerative neutrophils, and no neoplastic cells were found. Several neutrophils exhibited degenerative changes characterized by nuclear swelling and decreased chromatin condensation. Clinical improvement was evident within one week, with reduced swelling. Case was diagnosed as suppurative orchitis based on clinical and cytological findings. Case highlights the value of cytological examination as a rapid, minimally invasive diagnostic tool for testicular inflammation in small mammals, facilitating early diagnosis and appropriate therapeutic intervention. Particularly in settings with limited access to advanced diagnostic modalities.

Abstract

Background: African giant pouched rats are largely hunted and consumed in most African countries, leading to their rarity in the wildlife. Their breeding remains a major challenge with low reproductive success. Purpose: The present study aimed to determine the optimal post coital administration period of HPC that could maximize reproductive performances of FAGPR in captivity. Method: After mating, females of 8 months old were randomly distributed to three groups of 8 animals, housed singly with free access to water and feed. Each female was administered daily, an intramuscular injection of 16mg/kg bw of HPC. Group 1 was treated from day 3 to day 27, group 2 from day 3 to day 7, whereas group 3 received injections from day 7 to day 27 post coitus. Animals were observed until parturition, and reproductive performance was evaluated. Results: Pregnancy duration significantly increased (p<0.05) in group 1 (32.25±2.43 days) as compared to groups 2 (29.2±0.63 days) and 3 (29.83±0.98 days). Group 2 recorded the lowest fertile mating rate (85.93%) as compared to group 1 (100%) and 3 (93.75%). The stillbirth rate significantly increased (p<0.05) in groups 2 (8.3±3.24%) and 3 (7.06±1.03%) as compared to group 1 (3.57±1.84%). Litter size was significantly lower (p<0.05) in group 2 (5.4±0.86) compared to others groups. The highest viability of kids (89.88±9.26%) was observed in group 1 as compared to groups 2 (82.95±7.93%) and 3 (79.2±5.32%). Conclusion: The optimal administration period of HPC in FAGPR was extended from day 3 to day 27 post coitus for better reproductive success in captive breeding.

Abstract

Background: Rodents and shrews are linked to the transmission of pathogens through arthropod vectors. Purpose: This study determined the prevalence of ectoparasites in rodents and shrews associated with host species, habitat, and seasonality in Mgeta, Morogoro Region, Tanzania. Method: Using a cross sectional design, Sherman and wire traps captured rodents and shrews over six months across two seasons (wet and dry) in three habitats: households, farms, and forests stratified by elevation (low and high). Ectoparasites were processed, identified, and quantified. Results: A total of 200 rodents and shrews representing eight species: Montemys delectorum, Mastomys natalensis, Lophuromys machangui, Rattus rattus, Grammomys doilichurus, Crocidura sp., Otomys angoniensis and Mus musculus. The overall ectoparasite prevalence was 62.5%. The highest prevalence was of mites (50%, Laelaps sp.), followed by fleas (25%: Dinopsyllus spp. 19%, Ctenopthalmus spp. 3%, Xenopsylla brasiliensis 2.5%) and ticks (Haemaphysalis spp., 2.5%). Low forest habitat had the highest ectoparasite prevalence (19.5%), followed by high farm (18.5%), low farm (13%), high forest (8%) and indoor (3.5%). Habitat significantly influenced overall ectoparasite and mite prevalence. The dry season had a higher ectoparasite prevalence (43.5%) than the wet season (19%). Seasonality influenced flea and mite prevalence. Conclusion: The high prevalence of public health significant ectoparasites in rodents and shrews highlights disease transmission risks. Monitoring parasitic assemblages is imperative for disease control.

Abstract

Background: Canine ehrlichiosis is a tick-borne systemic infectious disease that causes multisystemic dysfunction, notably hematological alterations leading to pancytopenia during the chronic phase. Resulting immunosuppressive state increases host susceptibility to secondary opportunistic infections, including cystitis. Purpose: This case report aims to describe the clinical findings, diagnostic approach, and therapeutic management of chronic ehrlichiosis complicated by secondary cystitis in a 5 month old male mixed breed Siberian Husky puppy. Case (s): A 5.6 kg puppy presented with clinical signs of dysuria, hematuria, lethargy, and decreased appetite. Macroscopic urinalysis appeared unremarkable, but microscopic examination revealed pyuria, and urine dipstick testing confirmed cystitis. Ultrasonographic examination demonstrated thickening of the urinary bladder wall to 3.86 mm. Complete blood count confirmed pancytopenia characterized by leukopenia (3.77 × 10³/μL), granulocytopenia (0.65 × 10³/μL), anemia (3.41 × 10⁶/μL), and severe thrombocytopenia (23 × 10³/μL). The diagnosis of ehrlichiosis was confirmed by a rapid blood parasite test kit positive for Ehrlichia sp. Case Management: Cystitis was managed with amoxicillin (15 mg/kg BW PO q12h for 7 days), dexamethasone (0.1 mg/kg BW PO q24h for 3 days), vitamin B-complex supplementation (1 tablet/day for 7 days), and a urinary tract supplement (2 tablets/day for 5 days). Ehrlichia sp. infection was treated with doxycycline (10 mg/kg BW PO q24h for 28 days). Post treatment evaluation revealed clinical resolution of urinary signs; however, hematology showed persistent granulocytopenia and thrombocytopenia. Conclusion: Chronic ehrlichiosis can compromise immune function and predispose dogs to opportunistic urinary tract infections. Clinical improvement may precede complete hematological normalization, highlighting the importance of extended post-treatment clinical and hematological monitoring.

Abstract

Background: Rift Valley Fever (RVF) is a transboundary mosquito-borne disease affecting humans and animals in Sudan, causing public health issues, trade impacts, high young animal mortality with hemorrhage and liver damage, and flu-like symptoms in humans. This study addresses research gaps existing since the 2007 RVF epidemic. Purpose: To determine RVF seroprevalence in animals within the study area and assess risk factors associated with seropositivity. Method: Active surveillance and a cross-sectional study using ELISA were conducted. A total of 620 samples from sheep (n=304), goats (n=144), and cattle (n=172) were collected across three clusters selected via two-stage cluster sampling. Results: Overall RVF seroprevalence was 22.90%. Pearson‘s correlation between clinical signs and laboratory tests was positive (R=0.029). Sex, district, and society were significant predisposing factors (P<0.05; χ2=7.261, χ2=35.28, χ2=4.83). Univariate risk factors of species and mortality were not significant (P=0.461, P=0.465), and multivariate analysis showed no significant risk factors (P>0.05). Herd prevalence was 25% in sheep, 21.53% in goats, and 23.88% in cattle. Odds ratios were 0.81 for mortality, 1.6 for gender, and 0.74 for society. The test demonstrated 92.72% sensitivity and 86.46% specificity. Conclusion: Overall RVF seroprevalence was relatively high in 2007, potentially due to the epidemic peak. Further investigation is required to ascertain this fact, and more work is recommended.

Abstract

Background: Haliaeetus leucogaster, or the white-bellied sea eagle, is one of the largest raptors in Indonesia and plays a crucial role in maintaining ecological balance. Hematological evaluation is essential for assessing health and release suitability after rehabilitation; however, reference data for this species, especially from Indonesia, remain limited. Purpose: This study aimed to support clinical assessments and conservation strategies by, providing descriptive hematological data for H. leucogaster undergoing rehabilitation at the Bali Wildlife Rescue Centre, Indonesia. Method: Blood samples from five healthy H. leucogaster were analyzed at the Udayana University Veterinary Teaching Hospital. Measurements included erythrocyte and leukocyte counts, hematocrit, hemoglobin, erythrocyte indices (MCV, MCH, MCHC), and differential leukocyte counts. Morphology was documented using Optilab Viewer 2.2. Morphometry was measured using Image Raster 3. Data are presented as mean ± SD and range. Results: Mean erythrocyte count was 2.95±0.41×106/µL, hematocrit 48.80±5.60%, hemoglobin 10.54±1.29 g/dL, MCV 171.06±36.62 fL, MCH 37.41±10.14 pg, and MCHC 21.84±3.38 g/dL. Mean leukocyte count was 13.69±4.31×103/µL, with heterophil predominance (56.8±3.42%). Erythrocyte and leukocyte morphology and morphometry were consistent with normal avian raptor references. Monocytes were the largest leukocytes (13.09±0.86×12.19±1.08 µm, perimeter 41.13±2.33 µm) and basophils were the smallest (6.10±0.76×5.46±0.68 µm, perimeter 19.31±2.60 µm). Conclusion: Hematological values for H. leucogaster at the Bali Wildlife Rescue Centre fall within published references and provide preliminary data for individuals undergoing rehabilitation in Indonesia. These findings may assist veterinarians and rehabilitators in evaluating health status during rehabilitation and prior to release.
