Objectives: Knowledge, attitude, and practice (KAP) of rabies in the community are essential for developing post-exposure behavioral treatment and for understanding current prevention and control policy on rabies. This was a cross-sectional study in Gaibandha Sadar, a northern district of Bangladesh, investigating the level of KAP about rabies.  Materials and methods: A total of 368 interviewed respondents, of whom 280 (76.09%) were male, and 88 (23.91%) were female. A structured questionnaire was used for the data collection from respondents on socio-demographic information and KAP regarding rabies. The data analyzed with STATA-IC-11.0 and the association of independent variables with rabies KAP scores were cal­culated using Pearson’s Chi-square.  Results: Most respondents had adequate KAP levels and positive thoughts on rabies prevention. The KAP scores were strongly associated with education and employment status (p < 0.05). Most respondents said that stray dogs are a headache in the area and believed that control of the dog population in Gaibandha is essential.  Conclusion: These outcomes also revealed that there is an information gap about rabies that might improve by developing an education program for awareness.

Objective: This study aims at evaluating the anti-diabetic, hypolipidemic, and pancreatic histo­pathological changes of Rhizophora mucronata and Avicennia marina.  Materials and Methods: The experimental rats were divided into eight groups (n = 15 each). Streptozotocin was used to induce diabetes. Daily oral administration of an aqueous extract from the leaves of R. mucronata and A. marina at 400 mg/kg BW, and a mixture of the two extracts for 6 weeks was assessed. The measurements of serum glucose, insulin, and lipid profile were carried out. Pancreatic specimens were collected from all groups and processed for pathological studies.  Results: The study revealed that the plant extracts restored the levels of diabetic markers and lipid profiles of diabetic rats, with no significant changes in non-diabetic ones. The extract of R. mucronata exhibited more promising anti-diabetic and hypolipidemic effects than A. marina singly or combined.  Conclusion: Leaf extracts from R. mucronata, singly or combined, and A. marina, induced a potent anti-diabetic and hypolipidemic potential in diabetic rats.

Objective: The objective of this study was to assess the veracities of most admired strategy dis­criminant analysis (DA), in comparison to the artificial neural network (ANN) for the anticipation and classification of milk production level in Holstein Friesian cattle using their performances.  Materials and Methods: A total of 3,460 performance records of imported and locally born Holstein Friesian cows were gathered during the period from 2000 to 2016 to compare two alter­native techniques for predicting the level of production based on performance traits in dairy cattle with the use of statistical software (Statistical Package for the Social Sciences, version 20.0).  Results: The findings of the comparison indicated that ANN was more impressive in the expec­tancy of milk production level than did an imitator statistical method based on DA. The accuracy of the ANN model was high for the winter season (79.5%), whereas it was 47.3% for DA. The cur­rent findings were assured via the areas under receiver operating characteristic curves (AUROC) for DA and ANN. AUROC curves were smaller in the condition of the DA model across different calving seasons compared with the ANN model. The inaccuracies of variations were significant at a 5% significance level utilizing paired sample t-test.  Conclusion: ANN model can be used efficiently to predict the level of production across the differ­ent calving seasons compared to the DA model.

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 con­trol 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.

Objectives: This study was performed to probe the antimicrobial resistance and virulence genes profiling in Pseudomonas aeruginosa recovered from the cases of pericarditis in broiler chickens.  Materials and Methods: The samples (n = 250) collected from the cases of pericarditis in broiler chickens were bacteriologically examined. Antimicrobial susceptibility was tested by disc diffusion technique. The isolates were genotypically studied for the presence of antimicrobial resistance and virulence gene traits. Finally, the nucleotide sequence of representative resistance gene (mexR gene) and virulence genes (toxA and lasI genes) was analyzed.  Results: P. aeruginosa was isolated from 45 samples (18%). Antimicrobial susceptibility testing revealed multidrug resistance in most of the recovered P. aeruginosa isolates, whereas colistin and imipenem were the furthermost in vitro-sensitive antibiotics. Antimicrobial resistance genes, such as blaCTX, fox, and mexR, were prevalent in 100%, 80%, and 100% of the isolates, respectively. PCR confirmed virulence genes such as toxA, exoY, lasB, and lasI in 100%, 60%, 80%, and 80% of the isolates, respectively. Nucleotide sequence analysis of representative resistance gene (mexR gene) and virulence genes (toxA and lasI genes) revealed a high correlation between P. aeruginosa recovered from pericarditis in broiler chickens in the present study with PAO1 (reference strain) and with other sequences published on the GenBank representing different localities worldwide.  Conclusion: It could be concluded that P. aeruginosa recovered from pericarditis in broiler chick­ens in the current study is highly virulent bacteria, resisting most of the therapeutic agents which not only bear hazards for poultry industry but also represent a public health concern.

Objective: Annual health screening inclusive of heart workup is recommended for the detection of heart diseases, especially in asymptomatic patients (no clinical signs). This study determined the occurrences of the common heart disease and the risk factors in apparently healthy cats.  Material and methods: This prospective study that screened 59 healthy cats and the status of the heart were evaluated based on a combination of findings from physical examination, electrocar­diography, blood pressure measurement, routine blood test, urinalysis, and total thyroid level.  Results: Approximately 40.7% (n = 24/59) of the apparently healthy cats were diagnosed with heart disease hypertrophic cardiomyopathy (62.5%) remains to be the most commonly diag­nosed. The mean age was 4.9-year old (age range, 7-month-old to 19-year-old). The prevalence was higher in males (45.0%; n = 17/38) cats, especially the domestic shorthairs (46.0%; n = 11/24). Among the healthy cats with vertebral heart scale (VHS) > 8.0, only 52% (n = 12/23) of them were diagnosed with cardiomyopathy. However, 33% (n = 12/36) of the cats with normal VHS ≤ 7.9 were diagnosed with heart disease. Consistently, all healthy cats with abnormal heart sounds were diagnosed with heart disease. About 31.4% (n = 16/51) of these cats with typical heart sound had cardiomyopathy too.  Conclusion: The occurrence of cardiomyopathy in apparently healthy cats has no association with the patient’s age, sex, and VHS, except for the heart sound. Echocardiography remains the best diagnostic tool, as normal heart size and normal heart sound do not exclude cardiomyopathy in this group of apparently healthy cats. J. Adv. Vet. Anim.

Objective: Selenium (Se), as the form of selenite, is commonly supplemented in poultry diet, which has low bioavailability and high toxicity. Here, we compared the effects of the supplemen­tation of the diet with Se nanoparticles (nano-Se) on the growth, sexual behavior, and reproduc­tive performance (gonad size, sperm quality traits, and plasma testosterone levels for males and egg production for females) of Japanese quail (Coturnix coturnix japonica).  Materials and Methods: Quail chicks (n = 300) aging 14 days were divided into three groups: Group 1 (basal diet and Se at 0.2 mg/kg ration), Group 2 (basal diet and nano-Se at 0.2 mg/kg ration), and Group 3 (basal diet and nano-Se at 0.1 mg/kg ration). Several parameters relating to body weight and egg were measured. Sexual behaviors of the birds were observed by continuous visual scanning. The sperm viability, sperm morphology, and concentration of spermatozoa were determined after staining and microscopic examination. The plasma testosterone levels were determined by indirect enzyme immunoassay assay. The Se concentrations in the testicular, ovar­ian, and ration samples were measured by flame emission atomic absorption spectrophotometer.  Results: The type or concentration of nano-Se administration had no impact on body weight, feed efficiency, egg production, or egg weight. However, the total feed intake throughout the experi­ment was reduced in Group 2 at 0.2 mg/kg. Nano-Se supplementation significantly increased the sexual behavior. In general, the deposition of Se in the testicular and ovarian tissues increased with increasing supplement concentration. At the same supplement concentration, the tissue deposition of nano-Se was more enhanced than that of inorganic Se. Nano-Se supplementation improved the testicular functions by enhancing plasma testosterone level and sperm quality traits (sperm count, motility, and viability). This improvement was found more prominent with the lower supplement concentration (when comparing 0.1 vs. 0.2 mg/kg diet).  Conclusion: It is concluded that the use of nano-Se (at 0.1 mg/kg) in the ration of Japanese quail improves several reproductive performance parameters.

Objective: This study was carried out to study the influence of gender, neuter status, and training method on police dog narcotics olfaction performance, behavior, and welfare.  Materials and Methods: A total of 120 German Shepherds aged 1–3 years were used for this study. The dogs were separated into two experiments. The first experiment (32 dogs and 28 bitches) was used to study the influence of gender on olfaction and smell to narcotics in police dog perfor­mance and training methods with behavioral problems and welfare. The second experiment (30 dogs and 30 bitches) was used to study the influence of sexual status (entire or neutered) on the smelling of narcotics in police dog performance by comparing with intact dogs and bitches.  Results: We found that there were significant differences in sex in training to detect narcotics. Male German Shepherds were found to be significantly more trainable than females. Neutering causes a difference in trainability in male and female dogs. Gonadectomy had adverse effects on training. The intact male and female German Shepherds were found to be significantly more train­able than the neutered ones, and the reward-based method was found to be significantly more trainable than punishment. Dog training methods incorporated by punishment result in pain, suf­fering, emotional instability, symptoms of depression, aggression, unwanted barking, growling at other people, not under control all time, less trainability, increased problematic behavior, and decreased dog welfare.  Conclusion: Reward-based method is associated with lower lousy behavior and dogs with good behavior, such as, attachment attention behavior, dogs under the control of handler all times, higher trainability, less problematic behavior, and increased dog welfare.

Objective: In this research study, we explore the fluctuating asymmetry (FA) of palate Camelus hybrids and their parental species (dromedary and Bactrian).  Materials and Methods: We studied a sample of pictures from 27 adult skulls of pure Camelus dromedarius (n = 13), Camelus bactrianus (n = 7), and their crosses (n = 7), from two different col­lections. A set of 11 semilandmarks was located on the palatal region and was studied by means of geometric morphometric methods. The asymmetric variation was analyzed and evaluated for allometric effects, and variation among these three groups was studied using a canonical variates analysis.  Results: Among hybrids, there appeared a significantly lower amount of FA in comparison to the parental species, which may reflect the lower levels of genetic stress and higher levels of direc­tional asymmetry, which may suggest the presence of strongly transgressive mastication com­pared to pure species.  Conclusion: Camel hybrids would present increased developmental stability and better adapta­tion over those of parenteral lines.

Objectives: Antibacterial resistance is a great concern in human and food animal medicine, and it poses a significant concern in pet animals like dogs. This cross-sectional study was conducted to evaluate the antimicrobial resistance pattern of Escherichia coli, Staphylococcus spp., and Streptococcus spp. along with the carryover of some resistance genes in E. coli from dogs in the Chattogram metropolitan area, Bangladesh.  Materials and Methods: Rectal swab (n = 50), nasal swab (n = 50), and skin swab (n = 50) sam­ples were collected from dogs having respiratory infections, skin infections, and/or enteritis, respectively. Three types of bacteria were identified and isolated by conventional bacteriological techniques and biochemical tests. Antimicrobial susceptibility testing was carried out against 12 antimicrobials by disk diffusion methods. Six resistance genes, namely blaTEM, blaCTX-M, tetA, tetB, Sul-I, and Sul-II, were screened for phenotypically resistant E. coli isolates by the polymerase chain reaction.  Results: A total of 39 (78%) E. coli, 25 (50%) Staphylococcus spp., and 24 (48%) Streptococcus spp. isolates were isolated from the rectal swab, nasal swab, and skin swab samples, respectively. In the cultural sensitivity test, the E. coli isolates showed resistance to ceftriaxone (79%) and sulfa­methoxazole/trimethoprim (64%). Doxycycline (80%) demonstrated the highest resistance among Staphylococcus isolates, followed by sulfamethoxazole/trimethoprim (60%). Streptococcus iso­lates showed the highest resistance to penicillin (63%), followed by ceftriaxone (54%), while no isolate showed resistance to gentamycin. The prevalence of blaTEM, blaCTX-M, tetA, tetB, Sul-I, and Sul-II genes in phenotypically resistant E. coli isolates were 100%, 61.29%, 100%, 8.33%, 56%, and 72%, respectively.Conclusions: Spillover of such multidrug-resistant bacteria and resistance genes from pet dogs pose a serious public health risk.
