A Hanwoo cow with a delayed gestation and abdominal distension was delivered following PGF2α injection. There was excessive amniotic fluid, and a male calf was delivered but died immediately. The calf had no eyes and nose, and a cleft palate on the upper jaw. Gross appearance and computed tomography image showed that upper teeth were spread out on both sides due to cleft palate in the upper jaw, and lower jaw and teeth were positioned upward. There were no other brain parts except cerebellum. These findings show a rare case of hydramnios related to fetal congenital deformity in a Hanwoo cow.

Fungal diseases have risen in conjunction with the increasing number of immunosuppressive diseases in human and animal populations. Despite the introduction of new antifungal agents in recent years, the incidence of fungal infections continues to increase, and subsequently, the prevalence of resistance to these drugs is remarkably increased, posing significant health concerns. While antifungal drug resistance is of great importance in human medicine, especially against Candida spp., there are few studies about antifungal resistance in veterinary medicine. Indeed, several fungal infections include blastomycosis, candidiasis, coccidiomycosis, cryptococcosis, dermatophytosis, histoplasmosis, and Malassezia spp. infections have been reported in dogs and cats. Several antifungal drugs such as polyenes, azoles, pyrimidines, echinocandins, and allylamines have been encountered in feline and canine medicine. However, the desired success could not be obtained from the treatments applied in various cases in recent years due to antifungal resistance. This review aimed to emphasize the main common fungal infections in dogs and cats and the role of developing resistance against antifungal agents on treatment failures. Additionally, we discussed the mode of action of antifungal drugs, mechanisms of resistance, and factors that contribute to the emergence of resistance. In this context, monitoring of antifungal resistance in veterinary clinics and animal facilities by veterinarians and other animal health authorities is recommended.

The present study aimed to investigate the effects of nano-capsulated ivermectin on the liver and kidney function and oxidative status in mite infested-rabbits, compared to ivermectin. Additionally, the ivermectin residue profile in adipose tissue, liver, muscle, and kidney was evaluated. For this purpose, nano-capsulated ivermectin was prepared and characterized using high-resolution transmission electron microscopy (HRTEM) and cytotoxicity assay on Vero cells. To assess the effect of dose escalation of nano-capsulated ivermectin, one-hundred naturally mite-infested male rabbits were divided into four groups (G1-G4; n=25). Rabbits kept in G1 were left untreated (positive control), while rabbits kept in G2 and G3 received subcutaneously 200 and 400 μg/kg body weight ivermectin, respectively, at zero-day and repeated after two weeks of the first injection. Rabbits in G4 were treated with 200 μg/kg nano-capsulated ivermectin at zero day as a single dose. Additionally, twenty-five healthy male rabbits (G0) were used as a negative control. The efficacy was assessed based on clinical manifestations, liver and kidney function, and oxidative stress parameters. Ivermectin residues were measured in fat, liver, muscle, and kidney using high-performance liquid chromatography (HPLC). Results showed that the size of the nano-capsulated ivermectin was 35.4 nm with a narrow size distribution of 0.578 polydispersity indexes. A significant improvement in liver and kidney functions (P

A severe outbreak of Infectious Bursal Disease (IBD) was recorded in 30 chicken flocks in different districts in Sharkia governorate during 2019, with high mortalities (up to 30%) and severe immunosuppression. Attempts to control IBD by an antiviral iron oxide chitosan nanocomposite was conducted. Eighty 21-day-old Baladi broiler chicks were divided into 4 groups. Group A; served as the negative control group, group B; was the challenge control group, group C; was the nanocomposite treatment group, and group D; received nanocomposite. The treatment contained 1 mg/ 100ml IC50 of iron oxide chitosan nanocomposite via the oral route administered for 3 days post-infection (PI). Results revealed that the iron oxide chitosan nanocomposite nano-size was 35.1±5nm with a stable state, zeta potentials16.8 ± 10.9, the PDI 0.91 and iron concentration in nanocomposite was 2625 mg/L. The virus shedding showed a significant decrease (P

Campylobacteriosis is an emerging zoonotic enteric disease that poses a threat to both human health and animal productivity. Poultry is known as the primary reservoir of Campylobacter, and 90% of human Campylobacteriosis is caused by Campylobacter jejuni and Campylobacter coli. This is complicated by the worldwide emergence of Campylobacter strains that are resistant to commonly used antimicrobial compounds. In this study, we determined the prevalence and antimicrobial susceptibility profiles of Campylobacter coli isolated from cloacal swabs collected from broilers and layers in Mwanza and Arusha, Tanzania. We collected 402 cloacal swabs from broilers and layers. Then, samples were enriched into Bolton Broth supplemented with 5% laked horse blood. Campylobacter was isolated and confirmed by PCR. Antibiogram was done by disk diffusion method using six antibiotics i.e., ampicillin, nalidixic acid, gentamycin, erythromycin, tetracycline, and ciprofloxacin. Of the 402 samples, 31 (7.71%) were confirmed to be Campylobacter coli by PCR. In Mwanza, the overall prevalence was 6.5% (6% and 7% in broilers and layers, respectively), while in Arusha, the overall prevalence was 8.9% (10.8% and 7% in broilers and layers, respectively). Antimicrobial susceptibility testing showed that 80.6%, 16.1%, 9.7%, 9.7%, 6.5%, and 3.2% were resistant to ampicillin, nalidixic acid, erythromycin, tetracycline, ciprofloxacin, and gentamycin, respectively. The rate of antimicrobial resistance (AMR) to at least one antimicrobial was 100%. Eight out of thirty-one (12.9%) isolates were multi-drug-resistant to four different antimicrobial compounds, each with different patterns. Wise use of existing antimicrobials is necessary to curb the increasing trend of AMR strains.

Brucellosis is a zoonotic disease that has serious animal welfare and economic consequences worldwide. In mammals, this stealthy intracellular pathogen causes abortion and infertility, and in humans, it produces a terrible febrile illness that can progress into a long-term condition with serious implications. The pathogenicity of brucellae is based on their ability to survive and replicate in host cells, which allows them to escape from the immune system. The gold standard test for diagnosis, which demands competence, is still isolation and identification. Advancements in diagnostic procedures and screening of recently infected animals are required to achieve effective control. Despite their drawbacks, the most widely used vaccine strains to protect against Brucella infection and relevant abortions in cattle are B. abortus strains S19 and RB51 and in small ruminants is B. melitensis Rev1. However, there are no safe vaccine candidates for humans. Therefore, it is critical needs to improve vaccine production using advanced techniques such as subunit vaccines that are both effective and safe. Studying the overview of the Brucella immune response mechanism and advances in the diagnosis procedures allow more understanding of effective control strategies. The current review provides an overview on the immune response and updates on the diagnosis and control of brucellosis based on published literature on different search engines

The current study aimed to evaluate the objectivity of the vertebral heart scale in the right, left, and generalized cardiomegaly. The correlation between vertebral heart scale and cardiomegaly was determined by conventional methods using a detailed evaluation form of vertebral heart scale and main stem bronchus spine distance measurements and radiographic findings. For this reason, a detailed radiographic evaluation form, including cardiac shape alterations, tracheal displacement, the ratio of the width of the heart to the thorax, and effusive findings due to cardiac failure, was compiled to provide gradation and detection of both-sided alterations in latero-lateral and dorso-ventral view. X-rays of 189 symptomatic dogs with cardiac disorders were included in the study and evaluated by experienced staff. X-ray findings were classified as left-right and both-sided enlargement and graded as mild, moderate, or severe enlargement. Using statistical analysis, the vertebral heart scale method was found to be correlated with findings of left and generalized enlargement, and a significant difference was found between the moderate and severe class (respectively P

Light-emitting diodes (LED) have been gaining acceptance in agriculture applications as alternatives to incandescent light sources. Daylength intensity and spectral wavelength are important in poultry production and also, in some cases, serve as the only mean of light in some facilities. Therefore, Large White turkey hens of the same strain were reared to market weights using two different housing facilities in combination with different LED light treatments. Each treatment within the environmentally controlled facility (ECF) consisted of four replicate rooms, 16 rooms total in the facility. LED bulbs consisted of 5,000 Kelvin (K) or 2,700K LED in conjunction with a high or low foot-candle (FC) intensity level. Daylength was fixed at 14L:10D. Additionally, birds were reared in a natural curtain-sided facility (6 replicate pens) with exposure to natural light with a 75W incandescent bulb to maintain daylength consistency with the ECF. Performance parameters were measured at 0, 5th, 9th, and 12th week (wk) of age. Serum triiodothyronine (T3) and right eye measurements were taken at the 5th and 9th wk of age. Feather coverage was assessed at the 9th and 12th wk old as indicators of bird wellbeing. Novelty interactions for visual or nutritional items were recorded at 7th wk old. Spectral output within the same Kelvin temperature was significantly altered during dimming to achieve intensity levels. There were mixed performance results; however, cumulatively, birds reared under LED lighting, regardless of LED type or intensity level, had consistently increased body weight. Bird wellbeing was altered under 5,000K LED in combination with 2 FC as measured by a significant elongation of the anterior-posterior distance. However, the same effect was not measured in the 5,000K, 10 FC treatment, or in the 2,700K treatments, regardless of FC measurement. There were no differences among treatments for T3, feather coverage, or latency to approach or interact with novel items. When LED lights are used in environmentally controlled facilities, coupled with novelty interactions, birds maintained and excelled in performance parameters when compared to birds reared with natural light and ventilation conditions.

The increase in the house fly population (Musca domestica) indicates pollution from chicken farms due to the chicken feces produced. The house fly population from farms can be reduced by using Black Soldier Fly (BSF) larvae, but the exact number of BSF larvae has yet to be discovered to reduce the house fly population. This study aims to determine the presence of BSF larvae in chicken feces waste media in inhibiting the population of house flies. The research sample used 7-day-old BSF larvae from fishing for BSF flies from nature using organic waste to lay eggs and produce larvae. The research method used a completely randomized design (CRD) consisting of 4 treatments and 3 replications. Treatment without the addition of larvae (P0), 100 grams (P1), 200 grams (P2) and 300 grams (P3) into 1 kg of chicken feces stocked in a 50 cm x 50 cm container. The variable observed was the number of house flies perched on each treatment's feces. The results showed that the number of flies that landed on chicken feces with the addition of 0 g, 100 g, 200 g, and 300 g BSF larvae was 34.3312.09, 22.3310.21, 16.33 2.08 tails, 11.002.64 individuals. Based on the results of statistical analysis, it was found that the population of the house fly was significantly reduced (P0.05) between the addition of 0 grams of BSF larvae, 100 grams, 200 grams and 300 grams. The results of the study concluded that the more BSF larvae added, the less population of house flies perched around chicken feces. The presence of BSF larvae weighing 200 g per kg of chicken feces can reduce the population of flies that perch on chicken feces by 52%.

The leaves of Bandotan (Ageratum conyzoides) are a plant thought to have antibacterial properties. This study aims to determine the sensitivity of Bandotan leaf extract in inhibiting the growth of the bacteria Pseudomonas aeruginosa. This study used a stock extract of Bandotan leaves from the Pharmacology Laboratory and a bacterial isolate of P. aeruginosa in the Microbiology Laboratory of the Faculty of Veterinary Medicine, Universitas Syiah Kuala, which was identified by Gram staining, indole test, Methyl Red test, and confectionery test. The research method was carried out by planting the re-identified bacterial isolates on Nutrient Broth (NB) media, incubated at 37C for 24 hours. Then the turbidity composition of the isolates was arranged to match the turbidity in 0.5 McFarland solution. Furthermore, the sensitivity test of the extract on Mueller Hinton Agar (MHA) media was carried out by levelling the bacterial isolates on the surface of the media and attaching a disc containing bandotan leaf extract with a concentration of 25%, 50%, 75% and gentamicin disk as a positive control and distilled water as a negative control. All treatments were incubated at 37C for 24 hours, and then the inhibition zone was measured using millimeters (mm) callipers. The results showed that concentrations of 25%, 50% and 75%, respectively, had an inhibition zone of 8.16 mm, 9.82 mm, and 16.08 mm, respectively. In contrast, the average inhibition zone for gentamicin was 25, 30 mm and 0 mm distilled water. Therefore, it can be concluded that the Bandotan leaf extract is sensitive to growth inhibition of P. aeruginosa bacteria.
