Objective: This case report aims to discuss the veterinary approach taken to control a case of aspergillosis outbreak on a duck farm. Materials and Methods: A broiler duck farm with a population of 900 Muscovy ducks was having a complaint of a 5% mortality rate in their 3-week-old ducklings. Upon presentation, 10% of the ducks appeared to be listless, dyspneic, ruffled feathers, and cyanotic. Postmortem examination of the dead birds was conducted. The collected samples were subjected to isolation and iden¬tification of the associated Aspergillus fumigatus under the microscope using the scotch tape method. Results: Postmortem examination revealed whitish to creamy caseous nodules in the lungs, tho¬racic air sacs, gizzard, proventriculus, and intestines. Granuloma lesions and infiltration of inflam¬matory cells were observed in the lung and liver tissues. As for therapeutic management, all ducks were treated with copper sulfate, erythromycin, and multivitamins as the fungicide, antibiotic, and supplement, respectively, via drinking water. Conclusion: There is no effective treatment for Aspergillosis as the spores are difficult to destroy completely. Nonetheless, the disease can be controlled and prevented effectively with proper farm sanitation and providing a suitable feed storage environment to inhibit the growth of this opportunistic fungus.

Objective: Solubility and bioavailability are crucial for maximizing the activity of an antiparasitic drug. This study aimed to develop a combined preparation for antiparasitic medicines using iver¬mectin (Iver), fenbendazole (FBZ), and triclabendazole (TBZ), considering their solubility, bioavail¬ability, and activity. Materials and Methods: Innovative preparations in solid dispersions (SD) were obtained using the joint mechanical processing of drug substances with polyvinylpyrrolidone (PVP) in an LE-101 roller mill. The preparations efficacy was studied in 140 sheep spontaneously infected with gastroin¬testinal Strongylata, Dicrococelium dendriticum, Moniezia expansa, and Melophagus ovinus. The preparations were given individually to the sheep in the form of an aqueous suspension orally. Their effectiveness was evaluated using intravital and postmortem parasitological examinations. Results: The results confirmed the increase in solubility of substances by 1329 times. The exper¬iments have shown the high efficacy of SD composition of FBZ/Iver/PVP (1/1/9) containing FBZ (at 3.0 mg/kg b/w) and Iver (at 0.2 mg/kg b/w) when used against gastrointestinal Strongylates and M. expansa (95.8% and 100%, respectively), to a lesser extent against M. ovinus (38.5%). The SD composition of TBZ/Iver/PVP (1/1/9) of TBZ (at 3.0 mg/kg b/w) and Iver (at 0.2 mg/kg b/w) showed a high efficacy against gastrointestinal Strongylata and D. dendriticum (96.8% and 100%, respectively) and less activity against M. ovinus (61.6%). Conclusion: The high parasiticidal activity of SD based on FBZ, TBZ, and Iver in comparison with initial substances is explained by the formation of inclusion complexes of these substances with PVP when SD is dissolved in water and the synergistic effect of the active substances of the prepa¬rations. The resulting complexes have increased solubility in water and bioavailability. The use of such an SD suggests a significant reduction in the dosages of FBZ and TBZ without losing parasit¬icidal activity. [J Adv Vet Anim Res 2020; 7(4.000): 718-725]

Objective: Understanding intraspecific phenotypic plasticity is a prerequisite to fish stock identifi¬cation and sustainable fisheries management. In this study, we assessed intraspecific phenotypic plasticity in terms of meristic and morphometric characters of wild populations of elongate glassy perchlet, Chanda nama from two different rivers, namely Madhumati River Narail (MRN) and Tulshiganga River Jaypurhat (TRJ), and an ox-bow lake, Jhapa Baor Jashore (JBJ) in Bangladesh. Materials and Methods: In this study, six meristics, 15 conventional morphometrics, and 23-truss-based morphometrics were subjected to a one-way analysis of variance (ANOVA), followed by the Tukey-HSD test. The mean values of three meristic counts and nine conventional and 12 truss-based morphometrics demonstrated significant differences in the ANOVA test. Furthermore, principal component analysis (PCA) and discrimination function analysis (DFA) were performed separately using conventional and truss-based morphometric data. Results: In PCA analysis, four principal components were extracted and cumulatively demon¬strated 51.848%. On the contrary, two discriminant functions (DF1, 63.5%; DF2, 36.5%) resulted from DFA analysis. In the bi-plot alignment from the discriminant space, all individuals were exceedingly separated among the three inhabitants. A dendrogram developed using conventional and truss morphometric characters confirmed that two clusters were formed among three pop¬ulations. The TRJ population formed a distinct cluster, and the JBJ population formed a different cluster with a subcluster of MRN. In the discriminant function analysis, precise classification out¬comes displayed 82% of individuals into their unique populations, whereas 66.9% of individuals were categorized as a cross-validated assemblage. Conclusion: The baseline information resulting from the current study would be useful for envi¬ronmental studies and further conservation of glassy perchlet populations in Bangladesh.

Objective: The purpose of the experiment was to examine the effect of different food sources on the growth and reproduction performances of an epigeic earthworm Perionyx excavatus. Materials and Methods: The experiment was carried out in 18 cylindrical plastic containers for 10 weeks. The study was designed with six treatments, each having three replicates. In control treat¬ment (T1), cow dung was used as the only food source for the earthworm. In another five treat¬ments, water hyacinth (T2), chopped banana plant trunk (T3), vegetable scrap (T4), paddy straw (T5), and sugarcane bagasse (T6) were used as food sources with cow dung as bedding material. Results: The maximum weight gain of earthworm P. excavatus was 3,294.7 ± 4.5 mg for the food staff of vegetable scrap (T4). Earthworm P. excavatus fed with chopped banana plant trunk (T3) showed a very similar weight gain of 3,243.7 ± 3.8 mg. On the contrary, the minimum weight gain was 1,799.7 ± 3.5 mg for the food staff of paddy straw (T5). The maximum cocoon number of 137.33 ± 6.46 mg was observed in T3, whereas a minimum number of 36.67 ± 4.16 mg in T1. The highest number of hatchlings (12.33 ± 0.88 mg) was recorded in treatment T3, whereas the least number of hatchling (5.00 ± 0.58 mg) was observed in T1. Conclusion: It was concluded that, among the six different food sources, chopped banana plant trunk was preferable food source to the earthworm for growth and reproduction.

Objective: This study investigated the prevalence of Listeria monocytogenes in retail poultry shops, characterized the antibiotic resistance profile, and detected the genotypic pattern of vir¬ulence genes. Materials and Methods: Broiler meat (n = 90), intestinal content (n = 40), and environmental samples (n = 95) were collected for this study. Besides, hand swabs (n = 20) were obtained from the poultry shop workers and stool samples (n = 40) were collected from the outpatient clinics of Beni-Suef University Hospital, Egypt. The samples were subjected to isolation and identification of L. monocytogenes by conventional bacteriological examinations and biochemical tests, followed by confirmatory identification by the polymerase chain reaction. Results: Among the collected samples (n = 285), L. monocytogenes could be detected in 14.4% (n = 41/285) of the samples, where 30.0% (n = 12/40) of the intestinal content was positive. Similarly, 10.0% (n = 9/90), 15.0% (n = 3/20), and 12.5% (n = 5/40) of the samples of meat, hand swabs, and stools were found positive for L. monocytogenes, respectively. A total of 12 (12.6%) out of 95 environmental samples were positive for L. monocytogenes. Based on the antimicrobial sensitiv¬ity profile, most of the recovered isolates were multidrug-resistant against most commonly used antibiotics. Conclusion: The findings conclude that poultry shops play a vital role in transmitting L. monocy¬togenes to the consumers. Asymptomatic poultry shop workers should draw attention to their potentials for spreading the infection to the consumers through the contaminated carcasses. Low hygienic standards are present in commercial poultry shops that increase the risk of contamina¬tion in the sold products. [J Adv Vet Anim Res 2020; 7(4.000): 710-717]

Objective: Liver neoplasms are problematic among small domestic animals. The etiological cause of hepatocellular carcinomas in domestic animals is still unknown although it is believed that chronic infections and toxic substances can affect the development of this type of tumor. This study aimed to analyze the clinical and morphological characteristics of canine hepatocellular carcinoma. Materials and methods: In total, 6,958 cancer operations were performed in the clinic. Liver tumors were detected in 123 dogs in vivo and 375 dogs postmortem. All animals with suspected liver neoplasm were assessed, including history, clinical examination, complete blood count, biochemical blood tests, radiographic examination, and ultrasound with a biopsy for performing cytological and histological analyses. Results: Hepatocellular carcinomas have nonspecific clinical manifestations, also a characteristic aspect of other tumors of the hepatobiliary system. The hematological changes have an impact on the prognosis, and biochemical abnormalities reflect the changes in liver activity. The cytological diagnosis of hepatocellular tumors is difficult because of hepatocyte atypia in highly differenti¬ated carcinomas. Finally, a histological examination was performed in all the dogs diagnosed with hepatocellular carcinoma. Conclusion: Hematological changes in dogs with hepatocellular carcinoma affect their prognosis. Biochemical abnormalities of this pathology reflect the changes in liver activity, not indicating a specific pathology. However, an increase in the activity of aspartate aminotransferase, alanine aminotransferase, and alkaline phosphatase is an unfavorable prognostic sign. In this study, five of seven dogs with a tumor size of more than 5.0 cm had a life expectancy of 30, 51, and 91 days, suggesting that the size of the tumor is an adverse prognostic factor.

Objective: The current investigation was designed to point out the prevalence of multidrug-resis¬tant Streptococcus spp. causing acute clinical mastitis and their pattern of antibiotic resistance in dairy cows. Materials and methods: Milk was sampled from 128 dairy cows with 191 infected quarters during the period from August 2017 to December 2018. Bacterial species were isolated from the milk samples and identified based on colony morphology and biochemical tests. Multiplex PCR was done for confirmatory detection of the Streptococcus spp. isolates. Results: The chief isolation percentages, from the sampled milk, were Escherichia coli (26%), then Staphylococcus aureus (23%), and Streptococcus dysagalactiae (23%), then Streptococcus agalac¬tiae (20.1%), and finally coagulase-negative Staphylococci (7.7%). In confirmed PCR streptococci isolates, the antibiotic resistance genes have been detected, including macrolides antibiotic resis¬tance genes (ermB and mefA genes), lincosamides antibiotic resistance genes (linB gene), and tetra¬cycline resistance genes (tetM and tetO genes). Age, parity number, cleaning of bedding materials, cleaning of milking facilities, and utensils and udder cleaning practice were significant risk factors for multidrug-resistant streptococcal mastitis in dairy cows. Conclusion: The results of this study explored the phenotypic and genotypic traits of Streptococcus spp. which constitute a usual cause of acute clinical mastitis in dairy cows. The ermB, mefA, tetM, and tetO antibiotic-resistant genes were identified in streptococci isolates from dairy cows milk with acute clinical mastitis, indicating a public health hazard. Thus, veterinary clinical breakpoints are needed to improve surveillance data, improve the hygiene regimen on the farms, and pro¬mote the wise use of antimicrobials.

Objective: The purpose of this work was to investigate the effect of phosphodiesterase type 5 (PDE-5) inhibitor sildenafil citrate (SC) on the level of brain hippocampal neurophysiological parameters (inhibitory and excitatory neurotransmitters), oxidant/antioxidant status, minerals, and anxiety-like behavior using albino male rats. Materials and methods: A total of 24 albino male rats were allocated to three separate groups (each one had eight rats): control and SC 5 and 10 mg/kg treatments via i.p. infusion every 3 days for 12 injections. For the behavior of anxiety evaluation, the elevated plus maze test was conducted 1 day after the last treatment, and then all the rats were killed. For serum separation, the blood samples were taken, and hippocampus was dissected from the brain and stored frozen until analysis. Results: Both doses of sildenafil significantly improved brain hippocampal neurotransmitter [nor¬epinephrine, serotonin (5-hydroxytryptamine), and gamma-aminobutyric acid] values accompa¬nied by a decreased dopamine level. Interestingly, the SC higher given dose (10 mg/kg) increased the malondialdehyde level with the reduction of the antioxidant parameters [reduced glutathione (GSH) level, catalase (CAT), and superoxide dismutase (SOD) activities] although the lower dose of SC did not cause oxidative stress. Serum and brain hippocampal K, Cu, and Se concentrations were also increased with SC treatments. Moreover, the test of elevated plus maze revealed an anxiolytic impact of sildenafil. Conclusion: It was concluded that SC improved the parameters of some hippocampal neurotrans¬mitters and minerals accompanied by anxiolytic impact with the test of elevated plus maze, with a state of oxidative stress revealed with the higher dose of SC which was not recorded with the lower dose.

Objective: This study aimed to inspect the occurrence of Haemoproteus tinnunculi (H. tinnunculi) in falcons from the central area of Saudi Arabia. Materials and Methods: Blood samples from 100 falcons species, including 55 Falco cherrug, 22 Falco peregrinus, 13 Falco pelegrinoides, and 10 Falco rusticolus, were collected from November 2018 to April 2019 and examined for H. tinnunculi by microscopic examination and nested PCR, targeting a cytochrome b (cytb) gene. Results: The prevalence was 1% by microscopic examination. The prevalence rate of H. tinnunculi was 1% by the microscopic method and 3% by PCR. Only F. cherrug was infected. In the sequence and phylogenetic analyses, the two cytb H. tinnunculi sequences were 100% identical and closely related to the Lithuanian isolate with 99.35% identity. Conclusions: This study presents the first report of molecular detection and characterization of H. tinnunculai in F. cherrug from the Kingdom of Saudi Arabia.

Objective: This study aimed at determining the existence of oils and fats in ghee manufactured in Bangladesh and to validate the nature of the impurity. Materials and Methods: In this study, a ghee sample was prepared in the laboratory by follow¬ing standard methods and was used as a control sample. On the other hand, 19 ghee samples, including five branded samples (B1B5), and 14 local samples (L1L14) were collected from dif¬ferent manufacturers. The ghee samples were assessed for fat composition, Reichert Meissl (RM), saponification, Polenske, acid, Kirschner, and butyro refractometer (BR) values. To validate the ghee samples, vegetable oils and body fats were mixed in different ratios and then analyzed. Results: All the branded samples contained more than 99.5% fat, but only three local samples showed more than 97% fat. Admixing of soybean oil and coconut oil in different ratios showed the RM value from 1.57 ± 0.09 to 4.14 ± 0.21, whereas incorporation of hydrogenated vegetable oils and tallow showed 6.36 ± 0.03 to 14.10 ± 0.14. Nine local samples revealed RM values similar to external fat admixed samples. B2, B4, B5, L2L8, and L10L14 samples saponification values differed from the standard limits. Polenske, acid, Kirschner values and BR reading for L4, L6, L7, L8, L10, L12, L13, and L14 showed the worst results. All values varied significantly (p < 0.01). Conclusion: Local samples, L4, L6, L7, L8, L10, L12, L13, and L14, were assumed to be adulterated with external oils and fats. The quality of local ghee is questionable, as the samples contained more than 8% moisture, whereas pure ghee had less than 0.5% moisture. [J Adv Vet Anim Res 2020; 7(4.000): 678-684]

Objective: This study aimed at determining the existence of oils and fats in ghee manufactured in Bangladesh and to validate the nature of the impurity.  Materials and Methods: In this study, a ghee sample was prepared in the laboratory by follow­ing standard methods and was used as a control sample. On the other hand, 19 ghee samples, including five branded samples (B1–B5), and 14 local samples (L1–L14) were collected from dif­ferent manufacturers. The ghee samples were assessed for fat composition, Reichert Meissl (RM), saponification, Polenske, acid, Kirschner, and butyro refractometer (BR) values. To validate the ghee samples, vegetable oils and body fats were mixed in different ratios and then analyzed.  Results: All the branded samples contained more than 99.5% fat, but only three local samples showed more than 97% fat. Admixing of soybean oil and coconut oil in different ratios showed the RM value from 1.57 ± 0.09 to 4.14 ± 0.21, whereas incorporation of hydrogenated vegetable oils and tallow showed 6.36 ± 0.03 to 14.10 ± 0.14. Nine local samples revealed RM values similar to external fat admixed samples. B2, B4, B5, L2–L8, and L10–L14 samples’ saponification values differed from the standard limits. Polenske, acid, Kirschner values and BR reading for L4, L6, L7, L8, L10, L12, L13, and L14 showed the worst results. All values varied significantly (p < 0.01).  Conclusion: Local samples, L4, L6, L7, L8, L10, L12, L13, and L14, were assumed to be adulterated with external oils and fats. The quality of local ghee is questionable, as the samples contained more than 8% moisture, whereas pure ghee had less than 0.5% moisture. J. Adv. Vet. Anim.
