Abstract

Mouse has been an animal model that is very sensitive towards the Toxoplasma gondii infection. This research infects 30 mice with free-range chicken heart inoculate and the detection of T. gondiiby immunohistochemistry on the infected mice. The purpose of this study is to track T.gondii antigen expression by immune(cyto)histochemistry in mice. Observation over mice was conducted over 10 weeks. After 10 weeks, the mice are examined for its peritoneal fluid by microscopic and immunohistochemistry examination. Continued by the examination of internal organs to track the expression of T.gondii antigens by immunohistochemistry. The study result showed microscopic examinations on peritoneal fluid did not found any cyst or tachyzoites form of T.gondii. Examination of peritoneal fluid by immunohistochemistry was found to detect expressions of T.gondii antigen. Examinations of the mice’s internal organs detected expressions of T.gondii antigen only in the brain by immunohistochemistry examinations.

Abstract

A particular type of tumor that is frequently detected in female dogs who are sexually active is a mammary tumor. Neoplasia results from DNA-based alterations in cell cycle regulating genes. The mammary gland is prone to the formation of tumors due to its dynamic structure. The development of this tumor is supported by numerous variables. It has been recently discovered that there is substantial evidence linking the BRCA2 gene to the process of cancer. Standard examination techniques, such as fine needle aspiration, histopathology, and immunohistochemistry, are used along with ancillary tests to determine the tumor type and degree of malignancy. The primary treatment option for malignant tumors is surgical resection followed by adjuvant chemotherapy; benign tumors necessitate surgical resection as well. Adjuvant therapy options include hormone therapy and non-steroidal anti-inflammatory medications. Tumor tissue undergoes angiogenesis as it grows and develops to accommodate the abundant supply of nutrients. Therefore, angiogenesis-inhibiting therapies can be utilized to halt the growth of tumor cells. A number of antiangiogenic medications are now being studied in clinical settings on humans, and several more are undergoing trials on animals. In addition to pharmaceuticals, viruses may be used as a therapeutic to block tumor angiogenesis.

Abstract

A 14-year-old black male Poodle was brought to the Animal Teaching Hospital, Udayana University by its owner with clinical signs of frequent licking of its left front paw. Upon examination, red bumps were observed on the left front leg, accompanied by small, round black spots scattered on the dorsal side of the body. Additionally, black nodules were present on the lower eyelids and hind limbs. Surgical intervention was undertaken to excise the tumor mass, with the animal under anesthesia induced by ketamine at 5 mg/kg BW intravenously. The reddish nodule was excised by performing an elliptical incision at the base of tumor. Postoperatively, the animal received an antibacterial injection comprising ceftriaxone and tazobactam at 25 mg/kg BW intramuscularly and antiseptic wound dressing for supportive care. Microscopic examination revealed neoplastic cells arranged into lobules of varying sizes and shapes within the tumor mass. These lobules consisted of differentiated sebocytes and basaloid cells. At the periphery of the neoplastic lobules, the basaloid cells displayed several layers and exhibited invasion with moderate anisocytosis. The mitotic index was no more than ten cells in one field of view. Based on these histopathological features, the tumor was confirmed to be a sebaceous adenoma. After a 10-month follow-up period, there were no signs of tumor recurrence observed.

Abstract

c-Jun is often found to be overexpressed in various cancers, so this gene might be a target for cancer therapy. Newcastle disease virus (NDV) is recognized for its oncolytic properties and potential as a cancer virotherapy agent, with various mechanisms reported to trigger cancer cell death. This study aimed to assess the c-Jun expression in rat mammary cancer models. Rat mammary cancer models were categorized into two treatment groups: the control group (C) and the virotherapy group (V). Group C was administered with 0.5 cc of sterile PBS, while group V received 7 log 2 HAU per 0.5 cc of the Indonesian NDV field isolate Tabanan-1/ARP/2017 intratumorally. The treatment was carried out for four days in a row. Two weeks after treatment, all rats were humanely euthanized, and mammary cancer tissues were excised for further examination. Mammary cancer tissues were examined histopathologically and analyzed using immunohistochemistry to determine intranuclear c-Jun expression, quantified by the H-Score. The results demonstrated that NDV significantly reduced c-Jun expression. It can be inferred that NDV Tabanan-1/ARP/2017 holds potential as a mammary cancer therapy agent by reducing c-Jun expression. This finding is considered novel, as there have been no previous reports of decreased c-Jun expression following virotherapy with NDV.

Abstract

Avian Influenza (AI) is still endemic in Bali. This disease is very dangerous and deadly, is zoonotic in birds and humans and causes high economic losses. AI disease in poultry is caused by the Influenza virus type A. The aim of the examination is to identify the agent that caused the death of the chicken in the case to determine a definite diagnosis. The case chicken sample was a 29 day old broiler chicken from a farm in Jatiluwih Village, Tabanan Regency, Bali. Clinical symptoms of chickens include: weak chickens, shaking, shortness of breath, no appetite for eating or drinking, dull feathers, pale bluish combs, runny discharge from the beak, and white-brown watery feces. Chicken death occurred 2 days after clinical symptoms appeared. After the chicken dies, a necropsy is carried out and the samples are examined in the histopathology, virology, bacteriology and parasitology laboratories to determine the agent that caused the death. Histopathological examination showed that all organs had lesions. The results of the HA/HI test showed that the chicken was a positive case of being infected with the Avian Influenza virus. Bacterial infection testing in the media test, selective test, primary test, secondary test and confectionery test identified the presence of Staphylococcus sp bacteria. in the liver and lungs. The results of fecal examination during parasite examination using native and concentration methods did not reveal any worm eggs or protozoa. It was concluded that the case chicken was infected with Avian Influenza with secondary bacterial infection, namely Staphylococcus sp. It is recommended that breeders improve biosecurity and carry out routine and appropriate vaccinations to prevent Avian Influenza disease.

Abstract

The case pig originated from a farm in Tegal Suci Village, Sebatu District, Gianyar Regency, Bali. This case study review aims to establish the diagnosis of death in a 45-day-old female pig using anamnesis, epidemiological history, clinical symptoms, anatomical pathology examination, histopathology, and laboratory tests. The observed symptoms in the case pig included anorexia, weakness, and diarrhea. Necropsy results showed hemorrhaging in almost all organs of the case pig. Histopathological examination revealed lesions in the intestine, suggesting a Transmissible Gastroenteritis Virus (TGEV) infection, specifically intestinal villous atrophy. Bacteriological examination successfully isolated Escherichia coli bacteria in the lungs, liver, and heart. Fecal examination in the parasitology laboratory showed no evidence of worm eggs or protozoan infections. Based on a series of tests conducted, it can be concluded that the case pig is suspected to have been infected with TGEV and E. coli. Further testing is needed to investigate the co-infection of Transmissible Gastroenteritis Virus and E. coli in pigs to determine the appropriate treatment for severe diarrhea in pigs.

Data collection in the form of indications, anamnesis, epidemiological and laboratory examinations for further descriptive qualitative analysis. Clinical signs of pig include anorexia, weakness, diarrhea, fever (39.7oC), multifocal cyanosis of skin, severe neurological symptoms. Epidemiological data shows morbidity reaching 100%, mortality 78.94%, and case fatality rate 78.94%. An anatomical pathology examination was carried out through necropsy procedure and found hydropericardium, hemorrhage in the heart, brain, intestines, stomach, lungs, liver, kidneys had pthechie, while spleen changed color to dark and swollen, organ samples were collected for histopathology examination. Histopathological examination begins with histological preparations using Hematoxylin-Eosin (HE) staining. Examination were carried out by looking at the changes descriptively using binocular light microscope with 100x, 400x magnification. Histopathological examination showed that the brain (hemorrhagic meningitis), lungs (hemorrhagic interstitial pneumonia), heart (myocardial edematous), spleen (hemorrhagic spleen) and small intestine (necrotizing enteritis), large intestine (hemorrhagic et necrotizing colitis). In histology preparations, inflammation was found and dominated by lymphocyte cells and a few neutrophil cells. In bacteriological examination, Samples were isolated using Nutrient Agar, Blood Agar media. Bacterial identification then carried out using the Gram stain test, catalase test, Triple Sugar Iron Agar, Sulfide Indole Motility, Methyl Red Voges Proskauer, Simmon Citrate Agar, glucose test. Bacteriological examination confirmed the presence of Streptococcus suis bacterial infection in the brain, lungs, spleen. Parasitological examination of feces was carried out using native, floating and sedimentation methods, Eimeria spp. oocysts were found and calculated using quantitative methods with McMaster technique as 30,200 oocysts/gram. Based on all data and laboratory examination results, it was concluded that the pig was infected with African swine fever, Streptococcus suis and Eimeria spp. In pig farming management, strict biosecurity and sanitation must be implemented to minimize the risk of contamination by disease agents.

Abstract

Colibacillosis is a disease caused by pathogenic Escherichia coli bacteria. Infected piglets experience weight loss, stunted growth and if not treated immediately will cause death. A 16-day-old Landrace piglet died with clinical signs of weakness and yellowish white diarrhoea for 4 days. The farmer's population was 25 pigs. Epidemiology showed morbidity of 8%, mortality of 4%, and case fatality rate of 50%. Anatomical pathology examination revealed distended intestines with bleeding and hyperaemic lungs. Bacterial culture of lung and intestinal organs showed positive results of gram-negative Escherichia coli bacteria. The results of parasitological examination of native, sedimentation and floating methods were negative for protozoan and helminth infections. Histopathology showed congestion, haemorrhage and neutrophil-dominated inflammatory cell infiltration in the intestines and lungs, while the brain, heart and liver were congested. Based on all laboratory examination results, the case pig was diagnosed with colibacillosis. Improved sanitation and biosecurity of the barn and barn environment needs to be routinely carried out.
