Abstract

Escherichia coli is a coliform bacterium naturally found in the intestines of mammals. However, pathogenic strains, such as Avian Pathogenic Escherichia coli (APEC), can cause systemic infections and bacteremia in poultry. Infections by Escherichia coli in broilers lead to economic losses due to decreased production and increased mortality. This case report was conducted under protocol number 1/N/24, using anamnesis, clinical signs, epidemiological data, anatomical pathology, and histopathology observations to diagnose the condition. A 28-day-old white broiler chicken was collected from a closed house farm in Batungsel Village, Pupuan District, Tabanan Regency. Observed signs included lethargy, reduced appetite, an enlarged reddish abdomen, and white diarrhea. After the chicken's death, a necropsy was performed, and organ samples were preserved in 10% Neutral Buffered Formalin (NBF). Samples of the brain, lungs, liver, heart, spleen, kidneys, intestines, bursa, and feces were analyzed in histopathology, bacteriology, and parasitology laboratories. Histopathological preparations were stained with hematoxylin and eosin for microscopic examination. Bacterial infection tests included culturing samples from the intestines, liver, lungs, and heart on general, selective-differential, and Blood Agar media, followed by primary and secondary tests. The presence of Escherichia coli and Shigella sp. was confirmed. Parasite examinations using the flotation method showed no worm eggs or coccidia. These findings confirmed that the chicken was infected with Escherichia coli and Shigella sp.To prevent such infections, maintaining clean and sanitized housing is essential. Strict biosecurity measures are crucial to prevent external bacterial contamination. With good management practices, broiler chicken health can be optimally maintained.

Abstract

Animal-based foods are an important source of protein. However, the presence of pathogenic microbes such as Escherichia coli (E. coli) in food products can lead to serious issues concerning food safety and public health. This study aims to provide a literature review on the contamination of E. coli in various animal-based foods, including chicken meat, beef, fish, and milk, with a focus on several factors including the causes of contamination, its impact on food safety, and effective control measures. The research method used is a literature review utilizing various electronic sources. A total of 335 chicken meat samples were tested, with 270 positive and 65 negative results. A total of 73 beef samples were tested, with 63 positive and 10 negative results. A total of 16 fish samples were tested, with 9 positive and 7 negative results. A total of 37 milk samples were tested, with 15 positive and 22 negative results. The overall findings indicate that E. coli contamination in animal-based food products can occur at various stages, from production to distribution. This contamination can lead to foodborne diseases such as diarrhea and more serious gastrointestinal infections, especially in vulnerable populations. Factors such as hygiene and individual behavior, environmental conditions, cleanliness, and unhygienic processing methods are the main causes of the increased risk of contamination. The literature review discusses the importance of implementing food safety standards, biosecurity, and appropriate processing technologies to reduce the risk of contamination. Educating the public and food industry stakeholders on safe food handling practices is crucial in preventing foodborne diseases caused by E. coli.

Abstract

Lactoferrin in cow's milk is known as Bovine Lactoferrin (bLf). Currently, lactoferrin is being developed as an ingredient in vaccines and medicines. As a vaccine material, the plasmid gene bLf is expressed with Isopropyl-b-D-Thiogalactopyranoside (IPTG) to form recombinant proteins. The volume of IPTG used to induce gene expression depends on the bacteria's volume. Different concentrations of IPTG can generally affect the expression rate of recombinant proteins. Therefore, this study determined the optimal concentration of IPTG in expressing bLf protein. The study began with a gradual bLf culture from 1ml of Terrific Broth (TB) media, if the growth is good, upscaling to 10ml culture media. The bLf culture was incubated in a shaker incubator at a speed of 120rpm for 48 hours, at a temperature of 37ºC. After the growth of good bacteria, it was induced using IPTG with varying final concentrations of 0.125mM, 0.25mM, 0.5mM and 1mM. Re-incubated in a shaker incubator for 4-6 hours. The bLf culture was then centrifuged for 10 min at 6000rpm. Centrifugation results in the form of supernatants were removed, while the sediment was added as much as 300μl of PBS. The culture was ultrasonicated for 10 years with an amplitude of 50%. Furthermore, it was analyzed using the SDS-PAGE method. The test began by adding a buffer of 15μl to 45μl of sonicated results and heated at 95ºC for 10 minutes, then electrophoresis on acrylamide gel. The results showed that in each treatment or replicate there was a bLf protein. Visually, it was seen that there was no significant difference in the variation of IPTG concentration treatment for expressing the bLf plasmid gene. Adding IPTG to express bLf genes with lower or higher concentrations did not affect the bLf proteins produced. Lowering the IPTG concentration from 1μM to 0.125 can reduce production costs. Further testing is needed to use lower concentrations of IPTG in other plasmid genes.

Abstract

Increasing poultry populations and the use of conventional antibiotics to maintain the health of livestock and animal products have led to the development and spread of antimicrobial resistance (AMR), a global public health concern. The pattern of antibiotic use and misuse in broiler farming can be an implication of the emergence of various types of antibiotic-resistant bacteria and their spread among animals, humans, and the environment. The purpose of this literature review is to analyse the hazards associated with antibiotic use on broiler farms, the risk of antimicrobial resistance, and the potential consequences for animal, human and environmental health. In general, the negative impacts of antibiotic residues on human health include toxicological, microbiological and immunopathological hazards and economic impacts. Meanwhile, the impact of excessive use of antibiotics in livestock can lead to a weaker immune system, cause dysbacteriosis, the occurrence of secondary diseases or infections, residues in poultry products, and antibiotic resistance to pathogens. Furthermore, the overuse of antibiotics on broiler farms can result in pollution to the environment surrounding the farms that is distributed into soil, water, and plants. Therefore, effective mitigation of the risks associated with the extensive use of antimicrobials on broiler farms and management of AMR issues is essential, and requires a multidisciplinary integrated approach, such as the One Health approach to achieve optimal health and welfare outcomes and emphasize the interconnectedness between humans, animals and the environment.

Abstract

Long-tailed macaque (Macaca fascicularis) or also known as cynomolgus monkey and crab-eating monkey is one type of macaque that lives in Southeast Asia. Morphometric measurements aim to determine the morphometry of the long-tailed macaque itself and to determine the morphometric differences between adult male and female long-tailed macaques living on Mount Pusuk, North Lombok. This study uses the Length Measurements method with the research object being 17 samples of long-tailed macaques. The samples were analyzed by finding the average of each morphometric measurement parameter and comparing the morphometry between adult male and female long-tailed macaques. The results of the calculation of the average morphometry of adult long-tailed macaques living on Mount Pusuk are face width 75.00 mm; head length 121.12 mm; upper arm length 129.94 mm; lower arm length 133.76 mm; thigh length 139.76 mm; calf length 148.00 mm; sitting height 420.00 mm; and tail length 502.06 mm. From the calculation results, the morphometric size between adult male and female long-tailed monkeys living on Mount Pusuk differs significantly (P <0.05). The difference that can be seen is that the morphometry of male long-tailed monkeys is larger than that of female long-tailed monkeys. Further research is needed on the morphometry of long-tailed monkeys on different parameters and from various age groups to determine the development and comparison of long-tailed monkey morphometry.

Abstract

Platelet-rich plasma (PRP) has been identified as a potential therapeutic agent to mitigate factors that impede healing. PRP, which is enriched with growth factors, plays a critical role in accelerating tissue regeneration across various stages of wound repair. This study aimed to investigate the effects of PRP derived from porcine blood on the healing of incisional wounds in white rats (Rattus norvegicus). Macroscopic parameters, including wound length, wound color, moisture levels, and crust formation, were evaluated. The study employed an experimental design, utilizing a split-time completely randomized design (CRD) with statistical analysis. The results demonstrated significant improvements in wound closure, as evidenced by reduced wound length, accelerated changes in wound color, maintained wound moisture leading to faster drying, and enhanced crust formation, all of which contributed to a reduction in wound size (P < 0.05). These findings indicate that PRP derived from porcine blood significantly accelerates the healing process of incisional wounds in white rats, as reflected by macroscopic healing indicators. Further research is recommended to determine the optimal shelf life of PRP to ensure its efficacy and stability during prolonged storage, thereby supporting its sustainable clinical application.

Abstract

Squamous cell carcinoma is a non-melanoma malignant tumor originating from suprabasal epidermal keratinocyte cells. This tumor often occurs in elderly dogs in tropical countries due to ultraviolet radiation, viral infections, trauma, and immune status. The purpose of this article is to find out how to diagnose and treat squamous cell carcinoma cases in dogs. The case animal is a mixed breed dog, male, 10 years old, and weighs 21 kg. Clinical signs showed a lump with a solid consistency in the lateral left abdomen since 2 years. Based on the results of histopathological examination, the case dog was diagnosed with squamous cell carcinoma with a dubious prognosis. Treatment was carried out through surgical excision of tumor tissue, using general anesthesia with a combination of xylazine and ketamine with a total dose of xylazine 1.9 mg/kg BW and ketamine 9.5 mg/kg BW intravenously. Postoperatively, the dog was given cefotaxime antibiotic at a dose of 20 mg/kg BW intravenously (q12h) for 3 days and continued with oral cefixime antibiotic at a dose of 10 mg/kg BW (q12h) for 6 days. The dog was also given oral analgesic mefenamic acid at a dose of 10 mg/kg BW (q12h) for the first 3 days and continued with oral anti-inflammatory methylprednisolone at a dose of 0.4 mg/kg BW (q12h) for 6 days due to inflammation. On the 12th day, the surgical wound had healed as indicated by the skin had fused, was not swollen, the wound was dry, and the dog was actively moving. Further studies are needed on squamous cell carcinoma in dogs, and consideration should also be given to radiotherapy and/or chemotherapy to obtain better results.

Abstract

Caulerpa lentillifera is known as sea grapes macroalgae or sea grapes which have benefits as antioxidants. Paracetamol is a drug that is sold freely and many people abuse it. Abuse of paracetamol can cause negative impacts on various organs, one of which is the stomach and small intestine. The purpose of this study was to determine the effect of administering Caulerpa lentillifera on the histopathology of the gastric and small intestine of white mice given paracetamol in high doses. This study used a completely randomized design method. A sample of 25 male white mice was divided into 5 treatment groups, namely negative control (P0) or no treatment, positive control (P1) was only given paracetamol 250 mg/kgBB, P2 was given paracetamol 250 mg/kgBB and sea grapes 10 g/kgBB, P3 was given paracetamol 250 mg/kgBB and sea grapes 15 g/kgBB, and P4 was given paracetamol 250 mg/kgBB and sea grapes 20 g/kgBB. Treatment was given for 14 days, then necropsied. Samples of gastric and small intestine tissue were made into histopathology preparations using hematoxylin eosin (HE) staining. The variables examined in the gastric were gastric mucosal damage. While the variables examined in the small intestine included bleeding lesions and necrosis. Data were analyzed using the Kruskal Wallis Test followed by the Mann-Whitney test and described descriptively. The results showed that in gastric mucosal damage, small intestine necrosis, and small intestine bleeding showed that there was a difference (P<0.05) between groups. There was a process of improvement in the histopathology of the gastric and small intestine of white rats given Caulerpa lentillifera in gastric mucosal damage, small intestine necrosis, and small intestine bleeding. Based on the results of the study, it can be concluded that sea grapes with doses of 15 g/kgBB and 20 g/kgBB can minimize gastric mucosal damage. While a dose of 20 g/kgBB can minimize small intestine damage in necrosis and hemorrhage lesions
