This study aims to prove that the Moringa leaf extract can improve renal histological structure of diabetic Wistar rats. Wistar rats were divided into six groups, so that each group has four replications. K1 as the positive control was not given the extract, K2 was administered the extract dose 100 mg/kg, K3 was administered the extract dose 200 mg/kg, K4 was administered the extract dose 300 mg/kg, K5 was administered the extract dose 400 mg/kg, K6 was administered the extract dose 500 mg/kg. The administrations of extract were held for five weeks. Rats then sacrificed and the kidneys were taken for the histopathology preparations with Hematoxylin-Eosin staining (HE). The observations indicate fatty degeneration and necrosis of the kidneys. Kruskal Wallis test results of all treatments showed p = 0.001 in both fatty degeneration and necrosis (p <0.05).

ObjectiveStreptococcus suis (S. suis) is a causative agent for various syndromes in pigs. It can be transmitted to humans with typical symptoms of meningitis and death. Although human infections have been confirmed at Bali Referral Hospital, Indonesia, since 2014, the bacteria have not been isolated from pigs. Here, we provide confirmation of the presence of the bacteria in sick pigs in the province.ResultsStreptococcus suis was confirmed in 8 of 30 cases. The final confirmation was made using PCR and sequencing of the glutamate dehydrogenase (GDH) and recombination/repair protein (recN) gene fragments. Upon PCR serotyping, two were confirmed to be serotype 2 or 1/2. Prominent histopathological lesions of confirmed cases were meningitis, endocarditis, pericarditis, bronchopneumonia, enteritis and glomerulonephritis. The dominant inflammatory cells were neutrophils and macrophages. Further research is needed to understand the risk factors for human infection. Community awareness on the risk of contracting S. suis and vaccine development are needed to prevent human infections.

Muscovy duck parvovirus (MDPV) is threatening industry and backyard Muscovy duck poultry throughout the world. Here, we confirmed its presence in Indonesia for the first time. The outbreak described in this study occurred in a small fatty liver (French: foie gras) industry in Tabanan, Bali, and affected ducklings aged 2-3 weeks. Although older Muscovy ducks were present at the facility, they did not present signs of illness. Among the ducklings, the morbidity and mortality rates were 100% and 90%, respectively. The initial incidence began on 15 June 2014 and ended a month later. It reoccurred in January 2015. Clinical signs were lethargy, anorexia, watery diarrhoea, and dyspnea. The most frequent pathological lesions were cardiac enlargement with pale pericardia, haemorrhage, and enlargement of the liver. Dominant histopathology features were severe enteritis, epicarditis, and hepatitis. Using polymerase chain reaction (PCR) and published primer pairs NS1/REP and VP1, MDPV infection was confirmed with whole DNA isolated from the heart and liver homogenates. Sequencing of the PCR products resulted in 900 bp NS1/REP and 1200 bp VP1 fragments specific to MDPV. The virus sequences from the two separated incidences were completely homologous with one another. Now that MDPV has been detected in Indonesia, it should be included in the differential diagnosis when evaluating ducklings with MDPV-associated symptoms.

This study aims to determine the pathological changes in dog suspected of being infected by Leptospira spp. This research used a retrospective study design.  A total of 210 canines sample were examined at Faculty of Veterinary Medicine The Udayana of University between January 2008 to January 2010. Of the 210 specimens, five canines with clinical sign anorexia, fever, vomiting, polyurea, dyspnea and only one are noted icteric in the sclera. Macroscopically : the anemic to petechial haemorrhagis  was find in pulmo, icterus in liver with gall blader distention, kidney swollen with black color in hillus, spleen rather swollen with black color on end and mild hemorrhagis on intentines. The infected organ is inserted into a pot filled with neutral buffer formalin 10%. Then stained with haematoxyllin-eosin for the microscopic preparation. Microscopic examimination revealed  the presence of spiral bacterial cells on the necrotic liver and kidneys tissue.  Infiltration neutrophils and macrophages was also find in pulmonary and spleen tissue.  Besided that intertubuler edematous were also observed under  microscopic examination. It can be concluded changes associated with Leptospira spp infection can be found in liver and kidney tissue with changes such as necrosis, proliferation of kuffer cells and intertubular edematous.
