Objectives: This study aimed to examine the effects of wet-to-dry bandages for the treatment of surgical wounds in goats. Materials and Methods: Three types of bandages, i.e., the calcium alginate gel, the homogenous platelet-rich plasma (PRP) gel dressing, and saline dressing, were used to promote the healing process for the management of wounds. Artificial circular wounds were created and treated with bandages to evaluate their effects on the wound healing process in 12 goats. The morphological parameters, i.e., diameters (cm), duration of healing, and wound contraction (cm), were evalu¬ated to differentiate the postoperative sequelae on wound healing process up to day 30 in three different treatment groups of goats. Tissue specimens from the wounds were examined histo¬pathologically on 1st, 3rd, 7th, and 30th postoperative days. Finally, the obtained data were ana¬lyzed using the Statistical Package for the Social Sciences 19 software. Results: The current study revealed that the contraction diameter was higher in calcium alginate gel and PRP gel treated group when compared to the saline dressing group. Aggregation of immu¬noreactive cells (neutrophils, macrophages, and lymphocytes), collagen fiber bundles among the cells, and proliferation of blood vessels were observed in the epidermis of calcium alginate gel, PRP gel treated and saline dressing wounds, which promote the healing process of wounds. In visual inspection, the number of reactive cells and proliferation of blood vessels were higher in the calcium alginate gel and PRP gel treated group than the saline dressing. Conclusion: In terms of epithelialization, epidermal characteristics, neovascularization, and infil¬tration of immunoreactive cells, the calcium alginate gel and the homogenous PRP gel dressings showed the best healing performance. Therefore, the present study suggests that clinicians could consider the calcium alginate gel dressing and homogenous PRP gel dressing as beneficial for wound care.

Objectives: Migratory birds play a major role in the transmission of pathogens globally, but still their role in the transmission of fungi in Bangladesh is not known. The present study was carried out for the isolation and molecular detection of fungi including Aspergillus from migratory birds traveling to Bangladesh. Materials and methods: A total of 50 fecal samples were collected from BaojaniBaor, Magura, and areas close to Jahangirnagar University, Savar. The isolation of fungus was based on culture on Potato Dextrose Agar (PDA), followed by staining, morphology, and molecular detection using polymerase chain reaction (PCR). Results: Among 50 samples, 40 showed positive for fungal growth on PDA, of which 30 yield only yeast-like colonies, five only molds, and five yielded both yeast and molds. The isolated molds produced various pigmented colonies, namely, black, whitish, grayish, olive green, and yellow. Among 10 molds, six were confirmed as fungi by PCR using genus-specific primers such as ITS1 and ITS4. Later, of these six fungi, five were confirmed as Aspergillus by PCR with primers such as ASAP1 and ASAP2 specific for Aspergillus genus. Therefore, the overall occurrence of Aspergillus was 10% (5/50). PCR specific for Aspergillus fumigatus and Aspergillus niger failed to produce specific PCR amplicon, suggesting that the isolated Aspergillus belongs to other groups. Conclusion: This is the first report describing the isolation and molecular detection of Aspergillus from fecal samples of migratory birds in Bangladesh. The present findings confirm that migratory birds are potential source for Aspergillus and other fungus in Bangladesh. [J Adv Vet Anim Res 2020; 7(2.000): 338-344]

Objectives: This study was designed for the investigation of the effect of infection by Trypanosoma evansi on the changes of reproductive indices of the testis, causing reproductive failure in drom¬edary bulls (Camelus dromedarius). Material and methods: Seventy-five bulls were used for monitoring of the changes in the semen characteristics, reproductive hormones, hematobiochemical profiles, histopathological charac¬ters in the testis, and oxidative biomarkers. The animals were divided into two groups. Group A represented the uninfected or control group, while group B represented the infected group. Group B was again divided into two subgroups, such as acute and chronic infected animals. Results: Results showed that the semen analysis of infected camels revealed the presence of alterations in the morphology of sperms, especially the heads and tails, as compared to control animals. The hormonal profile indicated a significant decrease in the luteinizing hormone, folli¬cle-stimulating hormone, and testosterone levels, accompanied by the rise in the cortisol level in infected camels compared with the negative control. The histopathology and testicular degener¬ation were found to be associated with other disorders in infected camels. The oxidative profile and protein oxidation were promoted in infected testicles, indicating the occurrence of harmful effects in the cell. Conclusion: It is concluded that T. evansi infection in dromedary bulls causes severe damage to the testicular tissue and decreases the reproductive hormone levels associated with severe mor¬phological disorders in sperms due to oxidative stress resulting from the infection. All these find¬ings indicate that T. evansi can cause reproductive failure and fertility damage. [J Adv Vet Anim Res 2020; 7(3.000): 537-545]

Objective: The purpose of this study was to measure the mean concentrations of heavy metals including aluminum (Al), arsenic, nickel (Ni), mercury, lead (Pb), and cadmium (Cd) and to assess the health hazards due to the exposure of cattle/human population to a distinct or the mixture of heavy metals through various sources. Materials and methods: A total of 180 samples including water sources, animal feed, and raw cows milk from rural regions in Qena, Egypt, were examined using the inductively coupled plasma emission spectrometer (ICP; iCAP 6200). Results: The data highlighted heavy metal pollution with variable concentrations among most of the investigated regions. All concentrations of Al, Ni, and Cd detected in the feeding stuff showed a strong correlation to their respective levels in milk rather than those detected in water (R2= 0.072 vs. 0.039, 0.13 vs. 0.10, and 0.46 vs. 0.014, respectively) (p < 0.05). Anisocytosis and poi¬kilocytosis with a tendency to rouleaux formation were evident, and basophilic stippling was a pathognomic indicator for heavy metal toxicity, especially Pb. Leukopenia and macrocytic anemia were shown in 50% and 65% of examined cattle, respectively. The target hazard quotients values were more than one (>1) for all heavy metals from water intake for both children and adults and Al and Cd in milk for children, and the hazard index values were indicated higher for noncarcino¬genic health hazards. The target cancer risk values predispose people in the surveyed villages to higher cancerous risks due to exposures to the mixture of heavy metal through the consumption of water and milk. Conclusion: The bioaccumulation and transmission of heavy metal mixtures from water sources and feeding material have detrimental influences on milk pollution and cattle health which seem to be a serious issue affecting public health in those rural communities.

Objective: The aim of this experiment was to determine the effect of feeding pineapple waste silage (PWS) as the source of roughage replaced in Napier grass silage (NGS) on the nutrient intakes, energy status, and growth performances of growing Myanmar local cattle. Materials and methods: Eight growing Myanmar local cattle were randomly allocated into two groups, which were adjusted for age, sex, and body weight. Treatments were control (70% NGS + 30% concentrate) and PWS (45% NGS + 25% PWS + 30% concentrate). This experiment lasted for 6 weeks, including adaptation, and feed intake, energy status, and body weight gain were measured. Results: The higher (p < 0.05) intakes of dry matter, crude protein, non-fiber carbohydrate, neutral detergent fiber and energy, and energy balance were observed in the PSW group than in the con¬trol group. Although the initial and final body weights of both groups were not different (p > 0.05), the body weight gain and average daily gain were significantly higher (p < 0.05) in the PSW group than in the control group. Feeding PWS as a roughage source at 25% of diet improved the nutrient intake, energy balance, and body weight gain of growing Myanmar local cattle. Conclusion: Thus, PWS could be used as the source of roughage replaced in NGS in Myanmar local cattle with the improvement of productive performances. [J Adv Vet Anim Res 2020; 7(3.000): 436-441]

Objectives: The study was designed for isolation and identification of the bacteria present in unhatched leftover eggs of duck in selected mini-hatcheries of Kishoreganj, Bangladesh. Materials and Methods: A total of 54 unhatched discarded eggs were collected as samples from different mini-hatcheries of Tarail and Itna Upazilas of Kishoreganj and aseptically carried to the laboratory in the icebox. Surface washings (n = 54) and inner contents (n = 54) were collected and enriched in LuriaBertani broth followed by the isolation of pure colonies of different bacte¬ria onto eosin methylene blue agar, mannitol salt agar, SalmonellaShigella agar, and blood agar plates. Identification of the bacterial isolates was done by cultural properties, staining, and bio¬chemical tests followed by molecular detection by Polymerase chain reaction. Results: Of 108 samples, 62 were found positive for Salmonella spp. (76%), 59 for E. coli (54%), 52 for Staphylococcus spp. (48%), and 5 for Clostridium spp. (9%). From the egg surface samples, Staphylococcus spp. were recovered in the highest (67%) followed by Salmonella spp. (59%), E. coli (56%), and Clostridium spp. (9%). From the inner contents of eggs, Salmonella spp. were recovered in the highest (56%), followed by E. coli (53%) and Staphylococcus spp. (30%). Conclusion: The isolated bacteria might be associated with the decreased hatchability and embryo mortality in the mini-hatcheries of duck. [J Adv Vet Anim Res 2020; 7(1.000): 164-169]

Objective: This study aims to investigate the callipyge gene (CLPG) polymorphism in sheep of Edilbay, Volgograd, and Kalmyk breeds. Materials and Methods: The analysis was performed by the polymerase chain reactionrestric¬tion fragment length polymorphisms method. The objects of the study were Edilbay fat-tailed sheep (n = 500) at the breeding plant Volgograd-Edilbay (Volgograd region), Volgograd fine-wool sheep (n = 500) at the breeding plant Romashkovskiy (Volgograd region), and Kalmyk fat-tailed sheep (n = 500) at the breeding plant Kirovsky (the Republic of Kalmykia, Yashkul rayon). To conduct the research, tissue samples of 1 cm² from sheep of Kalmyk and Edilbay breeds were taken from the auricle. Results: The allelic CLPG gene variants have been determined and genotypes of representative sampling of the three breeds of livestock grown in the steppe zone of Russia. The presented results of the CLPG gene polymorphism in these sheep breeds grown in Russia were obtained for the first time. The research study has revealed that in terms of the CLPG gene, the Edilbay, Volgograd, and Kalmyk sheep breeds have only a homozygous form. Conclusion: The results obtained expand the current understanding of the molecular markers that characterize the meat qualities of sheep. [J Adv Vet Anim Res 2020; 7(1.000): 51-55]

Objective: The study aimed to explore the seroprevalence of some bacterial (Brucella spp., Chlamydia abortus) and viral [Rift Valley fever virus (RVFV), foot and mouth disease virus (FMDV)] zoonoses in domestic ruminants in Medina. Materials and Methods: A total of 1,000 blood samples from 665 sheep, 228 goats, and 107 camels were collected from the central slaughterhouse, private farms, and veterinary clinics affiliated to the Ministry of Agriculture. The samples were screened using the Enzyme-Linked Immunosorbent Assay (ELISA). The results were statistically analyzed using Statistical Package for the Social Sciences version 20. Results: Brucella was found in 7.7%, 8.8%, and 6.5% of sheep, goats, and camels sera, respec¬tively. In humans, Brucella abortus and Brucella melitensis had higher frequencies in males (61.3%, 59.8%) than in females (38.7%, 40.2%). Chlamydia abortus was reported only in sheep at a rate of 0.75%. RVFV was prevalent in sheep (10.7%) and goats (17.9%). FMDV was reported in 27.8% of sheep and 7.9% of goats. There was a highly statistical significance between Brucella, RVFV, and FMDV seropositivity and locally bred animals (p < 0.01). Multiple seropositivities have been reported among sheep and goats. Brucella was commonly observed in mixed infection with other bacterial and viral agents under study. Conclusion: The surveyed viral and bacterial agents were prevalent in ruminants in the Medina region. Since Medina is an important destination for pilgrims from all over the world, therefore, an integrated approach involving strict control measures and routine vaccination programs should be adopted to reduce the possibility of global epidemics.

Abhiram Karmaker | Pabitra Chandra Das | Abdullah Iqbal
Objective: This study aimed to assess the organoleptic, physico-chemical, and microbial quality as well as the presence of any adulterants in different commercial and local milk samples. Materials and Methods: Three brands of ultra-high temperature (UHT) milk, three brands of pasteurized milk, and three raw milk samples were procured and analyzed for different quality tests. Consumer preference about the milk samples were studied by evaluating the organoleptic properties by a testing panel of 15 panelists. Physico-chemical, adulteration, and microbial analysis of the milk samples were performed by following different standard methods. Results: Most of the organoleptic properties were varied significantly at p ≤ 0.05 for UHT and pasteurized milk samples, while raw milk samples were equally acceptable to the panelists in most cases. From physico-chemical analysis, it was found that raw milk contained the highest amount of moisture (90.68%), whereas UHT had the lowest (87.60%), and other components were ranged as 0.68%0.78% ash, 3.20%3.58% protein, 3.15%3.56% fat, 4.35%4.62% lactose, 0.14%0.22% acidity, 6.17%8.95% solid not fat, 9.32%12.40% total solid, and 1.026%1.034% specific gravity. All adulteration tests responded negatively for raw samples, whereas commercial milk samples showed positive response only on added sugar test. Total standard plate count and coliform count tests showed that there was no microorganism in a detectable range in commer¬cial milk samples, though raw samples had a significant amount. Conclusion: Though there were some fluctuations in some parameters of the three milk categories, but this study concluded that the quality of UHT and pasteurized milk were excellent with respect to parameters studied.

Objective: This study was carried out to find out the immunolocalization of Interleukin 6 (IL-6) and Interleukin 10 (IL-10) in the testicular tissue of testicular dysfunction rat treated with secretome from human umbilical stem cells. Materials and methods: Rats were induced with cisplatin for testicular dysfunction condition. After that, the rats were grouped into two categories and were treated with secretome at 0.2 and 0.5 ml/kg BW once every week for 4 weeks. One week later, after the secretome treatment, the rats were sacrificed for histological evaluation using the immunohistochemical method. The preparation slides were examined using a light microscope and were analyzed descriptively and quantitatively. Results: There were no IL-6 and IL-10 immunoreactivities seen in the testicular tissue after cispla¬tin induction. However, the immunoreactivities of IL-6 and IL-10 were detected after secretome treatment, with both dosages of 0.2 and 0.5 ml/kg BW. These immunoreactivities were detected in the spermatogonia, spermatid/luminal tissue of seminiferous tubule, spermatogenic cells, and Leydig cells. In the cell calculation, the numbers of IL-6 immunoreactive cells were higher at the lower secretome dosage. In contrast, the numbers of IL-10 immunoreactive cells were higher at the higher secretome dosage. Conclusion: IL-6 and IL-10 can be localized in the testicular tissue of testicular dysfunction rat after secretome treatment. [J Adv Vet Anim Res 2020; 7(3.000): 514-520]
