Objective: The study was conducted to investigate the gut content and record morphometric and hematological parameters in the common hoopoe (Upupa epops). Materials and Methods: Twenty samples of healthy birds (10 from each sex) were collected from different locations in Okara District, Punjab, Pakistan, from September 2020 to March 2021. Birds were captured live for blood samples and morphometric and gut analyses. Results: It was revealed that the concentrations of different hematological parameters were as follows: hemoglobin, 20.03g/dl; red blood cells, 3.28 × 106/μl; white blood cells, 326.67 × 103/ μl; hematocrit, 56.47%; MCV, 173.33 FL; MCH, 57.4 pg; MCHC, 57.4 pg; PLT, 8.33/μl; and RDW, 8.33/μl. The percentages of neutrophils, lymphocytes, monocytes, and eosinophils were 84.67%, 11.67%, 2.00%, and 1.67%, respectively. The gut content of the common hoopoe mostly consisted of Coleoptera and Acrididae larvae. However, Lepidoptera, Gryllotalpidae, and sand were also recorded, along with seeds of Salvadora persica. Conclusions: There were no significant differences between male and female U. epops in feeding content, total weight of the gut, or weight of the empty gut. Regarding the morphometric param¬eters, there was a significant difference in both sexes' wingspan, body length, and body weight. Males were significantly heavier than females.

Objectives: This study aimed to prove the effects of Escherichia coli isolates isolated from dis¬eased broilers to form biofilms, describe their antimicrobial sensetivity, and determine the effect of allicin and cinnamon essential oils on the expression of some genes (fimH, int1, and luxS) through quantitative polymerase chain reaction (q-PCR). Materials and Methods: 140 samples were obtained from diseased broilers in Beni-Suef Governorate, Egypt. These samples were examined by conventional bacteriology methods to detect the causative agent. The antimicrobial susceptibility of the isolated bacteria was assessed using the disc diffusion method, The ability of yeast extract-casamino acids Congo Red Agar to generate phenotypic biofilms was next tested. The presence of resistance and virulence genes in some multidrug resistant isolates was genotypically investigated. The antibacterial effects of allicin and cinnamon oil were evaluated against the growth of multidrug-resistant E. coli. Finally, q-PCR was utilized to assess changes in some genes' expression. Results: Escherichia coli was isolated from 61 samples (43.6%). An antimicrobial susceptibility test revealed that multidrug-resistance (MDR) (could resist more than three antimicrobial classes) E. coli prevalence was 100%. 40.8% of isolates phenotypically produce biofilms. The detection of resistance and virulence genes by PCR showed that all tested isolates carry aadB, fimH, int1, qnrS, and luxS genes, while only 40% harbor iss genes. q-PCR showed that after treatment with allicin and cinnamon oils, gene expression went down. Conclusion: This investigation highlights that E. coli showed resistance against most of the tested antimicrobials; all isolates were MDR. The study showed wide dissemination of virulence and resistance genes among E. coli. Allicin and cinnamon oils have antimicrobial activities and could be used as alternatives to synthetic antimicrobial agents. [J Adv Vet Anim Res 2022; 9(2.000): 191-202]

Objective: This short study describes the occurrence of pathogenic Leptospira spp. in two major wet markets in Kota Bharu, Kelantan, Malaysia. Materials and Methods: 30 rodents (20 rats and 10 shrews) were caught in 2 wet markets, and a postmortem was performed to extract both kidneys. Molecular diagnosis via polymerase chain reaction (PCR) was conducted to detect leptospiral DNA using universal and pathogenic Leptospira primers, respectively. Results: The results showed that 20/28 (72%) rat samples were detected positive for Leptospira spp, and all shrews were negative. Further sequencing analysis identified L. interrogans and L. borgpetersenii as the most frequently Leptospirosis species from kidney samples. Conclusions: The presented study here sheds light on the presence of pathogenic leptospires har¬boring the rat population in both wet markets in Kelantan, which presents a great public health risk to wet market workers and visitors.

Anthrax is a rapidly fatal infectious disease affecting herbivores and people. In the farm ani¬mals, cattle and sheep are more susceptible, followed by goats and horses, while dwarf pigs and Algerian sheep are relatively resistant. Bacillus anthracis, the causative agent of anthrax, produces spores and persists for decades in the soil, initiating an outbreak through a favorable climate shift. Anthrax is enzootic in many Asian and African countries, and is reported in Australia, some parts of Europe, and America. The clinical courses of this disease in animals are peracute, acute, sub¬acute, and chronic forms. In severely infected cases, the animals are dead without premonitory clinical signs. The blood may fail to clot and can be found in the mouth, nostrils, and anus in the animals that die from anthrax. This bacterium is susceptible to many antibiotics, yet only penicillin and oxytetracycline have the most effective under field conditions. When an outbreak occurs in a defined area, it is necessary to take early steps to break the infection cycle by maintaining strict biosecurity and vaccinating uninfected animals. This disease is still a challenge to farm animal production in many countries. This review intends to give a fair knowledge of the etiology, epi¬demiology, pathogenesis, clinical presentation, diagnosis, treatment, and control of this disease.

Objective: A 35-day-long trial was conducted to compare the consequences of supplementing citric acid (CA), Spirulina platensis, and their combination as natural substitutes for antibiotic growth promoters (AGP) on the productive performance, dressing percentage, and blood serum metabolites of broilers. Materials and Methods: A total of 150-day-old Cobb-500 broiler chicks were randomly assigned to 5 dietary treatment groups, each having 30 chicks in it (10 chicks per replicate cage). The dietary groups were as follows: 1- Control (corn–soybean-based), 2- Control + antibiotic (Enrofloxacin, 10 mg/kg bodyweight), 3- Control + 1% S. platensis, 4- Control + 0.5% CA, and 5- Control + 1% spirulina + 0.5% CA. Starting from day 7 up to day 21, antibiotics were administered via water; spirulina and CA were offered via feed. Results: When compared to the control, all dietary supplements significantly (p < 0.05) improved broiler growth performance. However, dressing characteristics and serum metabolites (serum creatinine, albumin, and uric acid) were not influenced (p > 0.05) by dietary changes, except cholesterol level (p < 0.05). Supplementation with antibiotics, CA, and spirulina produced com-parable results. Among them, the CA-fed group recorded the highest live weight, weight gain, feed intake, improved feed conversion ratio, and the lowest serum cholesterol level (106.5 mg/ dl). The combination group performed better than the control, but not as well as their single supplementations. Conclusions: CA and S. platensis might both be good candidates as natural alternatives to AGP (Enrofloxacin). But, among them, CA performed better in terms of production performance.

Objectives: The objective of this study was to evaluate the persistence of oxytetracycline (OTC) residue in common fish species (Catla, Rui, Mrigal, and Pangas) available in local fish markets and the corresponding transport water of the Mymensingh region. Materials and Methods: Live fish and corresponding transport water samples were analyzed by thin layer chromatography (TLC) and high-performance liquid chromatography for qualitative and quantitative detection of OTC residue, respectively. A total of 240 fish samples and 60 water samples were randomly collected from three local fish markets during the summer and winter seasons. Results: OTC residues were detected in 18 samples (13 fish and 5 water samples) in the summer and 8 samples (only fish samples) in the winter. The overall percentage of antibiotic residue positive in fish samples was 5.42%, and in water samples, it was 8.33%. In fish, OTC concentrations of TLC-positive samples ranged from 34.7 to 56.85 parts per billion (ppb) in Catla, 23.45–35.37 in Rui, 11.02–26.80 in Mrigal, and 10.80–77.55 in Pangas during summer. The concentrations were 18.5 ppb in Catla, 15–16.09 in Rui, 10–14.63 in Mrigal, and 21.02–40.11 in Pangas during the win¬ter season. On the other hand, the range of OTC concentrations of TLC-positive samples for water was 12.9–59.18 ppb during summer and below the detection level during winter. The highest prevalence of antibiotic residues among fish samples was found in Pangas (16.67%). The highest percentage of samples (15% in the fish sample and 30% in the water sample) found to be positive were collected from Mechua Bazar. The comparison between the summer and winter seasons showed that the percentage of positive antibiotic residue in the summer season (10.38% for fish and 16.67% for water) is higher than that of the winter season (6.67% for fish samples only). This variation indicates that fish transporters use more antibiotics during the summer than in the winter season. The difference between the means of fish species and water samples was not statistically significant (p &gt; 0.05). In addition, no samples exceeded the maximum residue limits (MRL) of OTC (100 ppb) in fish set by the European Commission. Conclusion: Although the concentrations of antibiotic residues in fish edible tissues are below MRL values, the presence of antibiotic residues in transported water may lead to the development of antimicrobial resistance bacteria that are detrimental to humans, animals, and aquatic animals.

Objective: The current broiler trial was planned to assess the effects of Kolin Plus™, a polyherbal formulation (PHF), on performance, protein and fat accretion, and serum L-carnitine (LC) levels in broilers fed a high-energy diet (HED). Materials and Methods: A total of 500 1-day-old Cobb 430 male chicks were assigned to 5 treat¬ment groups consisting of 10 replicates, with 10 birds in each replicate (n = 100). Group G1 was a negative control fed HED, and group G2, a positive control supplemented with synthetic choline chloride (SCC) 1,500 gm/ton in HED. Groups G3, G4, and G5 were supplemented with PHF in HED at 400, 500, and 750 gm/ton feed, respectively (PHF400, PHF500, and PHF750). Results: The PHF produced a dose-dependent numerical improvement in body weight, feed con¬version ratio, livability, and the European Production Index. There were no changes in carcass nitrogen and protein accretion, whereas a statistically significant decrease (p &lt; 0.05) in carcass fat and fat accretion was observed in the SCC and PHF groups. Moreover, PHF showed a significant increase in serum LC levels. Conclusion: Kolin Plus™ improves performance parameters akin to SCC by improving fat metabo¬lism and mobilization by enhancing serum LC levels and restoring normal fat accretion.

Objective: The current broiler trial was planned to assess the effects of Kolin Plus™, a polyherbal formulation (PHF), on performance, protein and fat accretion, and serum L-carnitine (LC) levels in broilers fed a high-energy diet (HED). Materials and Methods: A total of 500 1-day-old Cobb 430 male chicks were assigned to 5 treat¬ment groups consisting of 10 replicates, with 10 birds in each replicate (n = 100). Group G1 was a negative control fed HED, and group G2, a positive control supplemented with synthetic choline chloride (SCC) 1,500 gm/ton in HED. Groups G3, G4, and G5 were supplemented with PHF in HED at 400, 500, and 750 gm/ton feed, respectively (PHF400, PHF500, and PHF750). Results: The PHF produced a dose-dependent numerical improvement in body weight, feed con¬version ratio, livability, and the European Production Index. There were no changes in carcass nitrogen and protein accretion, whereas a statistically significant decrease (p < 0.05) in carcass fat and fat accretion was observed in the SCC and PHF groups. Moreover, PHF showed a significant increase in serum LC levels. Conclusion: Kolin Plus™ improves performance parameters akin to SCC by improving fat metabo¬lism and mobilization by enhancing serum LC levels and restoring normal fat accretion.

Objective: Brucellosis is an endemic zoonotic infection in Saudi Arabia, including Jazan Province, and epidemiological reports about this disease are limited. In this study, we aimed to investigate knowledge, attitudes, and practices regarding brucellosis among the general population of Jazan Province, southwestern Saudi Arabia. Materials and Methods: This is a cross-sectional study conducted using a pretested questionnaire that assessed the level of knowledge, attitudes, and practices toward Brucellosis. The calculated sample size was 384, and 1,055 participants were included representing various genders, ages, and levels of education. Data were collected between March and April 2022 and analyzed using descriptive, chi-square, and t-test analyses. Results: Only 50% of the included participants have heard about Brucellosis. Among those who had heard about Brucellosis, 70% had a good knowledge about Brucellosis and that was significantly associated with male gender, being healthcare workers (HCWs), and having a higher level of education. Participants who directly involved in animal care represented 9%, and attitudes and practices regarding brucellosis were varied from average to unsatisfactory. This variation was significantly affected by the level of knowledge. Conclusion: About 50% of the general population of Jazan Province had never heard about Brucellosis, in a region found prevalent for this disease. Good knowledge was recorded in 70% of those who were aware of Brucellosis, which was significantly associated with the male sex, job as being HCW, and having a higher level of education. These results necessitate public awareness campaign activities to improve knowledge and practices, especially among women, the younger generation, and individuals with limited educational backgrounds. This action could reduce the burden of the disease. [J Adv Vet Anim Res 2022; 9(4.000): 761-769]

Objective: This study describes the newest deoxyribonucleic acid (DNA) barcoding Asian redtail catfish (Hemibagrus nemurus) in the Progo River, Magelang, Central Java, Indonesia. Materials and Methods: Ten fish were caught in the Progo River, Magelang, Central Java, Indonesia. The polymerase chain reaction was the molecular diagnosis to detect the sequences of DNA of Cytochrome Oxidase I compared to National Center for Biotechnology Information data (GenBank). Results: The results showed that the percent identity was not 100% with H. nemurus data from other locations (GenBank), including Indonesia. The closest percent identity was H. nemurus from Java Island (Accession ID: MK312566.1) with 97.6% similarity. The genetic mutation that hap¬pened might be due to environmental change (pollution) in the Progo River recently. Conclusions: This study showed a genetic mutation in H. nemurus from Progo River may be caused by environmental change. Low pollution exposure levels may not be detrimental (lethal) to fish. However, it can affect fish fertility, which leads to population degradation (gene variation). Attention must be increased for fish survival in the future.

Objectives: This study was designed to detect Riemerella anatipestifer through polymerase chain reaction (PCR) from duck farming areas of the Mymensingh and Sylhet divisions and to determine the antibiogram profile of the PCR-positive isolates using the disc diffusion method. Materials and Methods: Fifty two samples were collected, comprising clinically sick (32 ducks) and dead ducks (20). PCR confirmation was accomplished, and consistent findings were observed, employing R. anatipestifer groEL (271-bp) gene as appropriate molecular markers. For further clarification, see R. anatipestifer specific PCR assay (546-bp) and gyrB-based PCR (162-bp) were also done. The disc diffusion method was followed for the antibiotic susceptibility test of the iso¬lates against commonly used antibiotics. Results: A total of 21 samples, 8 from clinically sick birds and 13 from dead birds, showed positive results in both conventional and molecular assays out of 52 samples. High occurrences were found in oropharyngeal swabs from sick ducks and the liver and heart from dead ducks. Antibiotic susceptibility testing revealed that the isolates were 100% resistant to penicillin G, cefradine, streptomycin, neomycin, gentamycin, meropenem, and erythromycin, but 100% sensitive to cotrimoxazole, florfenicol, and levofloxacin. Conclusion: For diverse duck-populated areas in Bangladesh, this study shows the severity of R. anatipestifer infection among ducks. [J Adv Vet Anim Res 2022; 9(4.000): 684-693]
