    A 5-month-old Siamese cross kitten was presented with jaundice and a palpable abdominal mass at the right cranial quadrant. The extra-hepatic biliary system was markedly distended upon abdominal ultrasonography. Complete bile duct obstruction was ruled out due to the presence of urobilinogen, light brown stool, and consistentlynormal alkaline phosphatase (ALP) levels. Head tremors developed on the second day of hospitalization. Tentative diagnoses of congenital biliary anomaly and hepatic encephalopathy werederived and exploratory laparotomy revealed a severely distended and tortuous bile duct indistinguishable from the gallbladder with negative duodenal filling. Modified cholechoduodenostomy was performed however the kitten did not recover from general anaesthesia. Secondary cholangiohepatitis and hepatic encephalopathy were confirmed upon histopathologic examination.Primary congenital biliary atresia or choledochal cyst with secondary cholangiohepatitis was suspected. Biliary anomalies are rare in cats with only two cases reported in the literature. These conditions are often challenging to diagnose and due to the limited treatment options, have a poor prognosis.

    A six-year-old Thoroughbred race horse was presented with left unilateral mucopurulent nasal discharge. Endoscopic examination revealed atypical mycotic lesion within the guttural pouch in which the fungal mass was not located on any neurovascular structures. This case was successfully treated by the combination of manual debulking of fungal diphtheritic plaques and medical treatment that included daily local irrigation and systemic medication. There were no complications and the horse returned to race three weeks later.

    A tourist was infected with a new strain of leptospires namely, Leptospira icterohemorrhagiae serovar Lai strain Langkawi, when he was on vacation in Langkawi, Malaysia. The leptospiral strain was successfully isolated from the patient in the Netherland. In this study, the bacteria were retrieved from Holland and inoculated into fifteen guinea pigs in Universiti Putra Malaysia (UPM) to determine its pathogenicity. The main clinical symptoms in the guinea pigs were decreased appetite and jaundice. Blood profile showed high neutrophil, lymphocyte, PCV, RBC, haemoglobin, leukocyte and thrombocyte counts. Besides that, enhancement of electrolytes such as sodium (Na), chloride (Cl), and potassium (K) was also noted. Biochemical examination showed an increase alkaline phosphatase (ALP), aspartate transaminase (AST) and bilirubin levels. Albumin, alanine transaminase (ALT), blood urea, total protein and creatinine were low values. Histopathological examination under haematoxylin and eosin staining showed evidence of haemorrhages, congestion and oedema in all organs, with inflammatory cell infiltration characterized by neutrophils, lymphocytes and macrophages. Hydropic degeneration and cell necrosis were also common in the findings. Leptospires were detected from Day 2 p.i by silver staining and transmission electron microscopy (TEM). Rise in antibody titre was seen as early as Day 5 p.i and leptospiral DNA was detected by PCR in the kidneys and liver on Day 3 and Day 5, respectively. The findings were indicative of leptospirosis. This study demonstrated that guinea pigs are a suitable animal model to illustrate the clinical symptoms and pathological changes seen following infection with Leptospira icterohaemorrhagiae serovar Lai strain Langkawi. In general, the symptoms and changes seen in leptospirosis are similar to viral infections and the information and data from this present study would help differentiate infection due to leptospires from that of viral infection. Leptospiral infection has often been misdiagnosed to be viral infection such as influenza and dengue which have similar signs and symptoms as leptospirosis.

    An 11-year-old intact male Shih Tzu dog was referred to the University Veterinary Hospital (UVH) with history of coughing and laboured breathing. Auscultation revealed that the dog had a left systolic heart murmur grade V/VI at the base of the heart. Radiography showed findings of cardiomegaly and pulmonary oedema. Echocardiography findings revealed that dog has a myxomatous mitral valve disease. The mitral valve was severely thickened and prolapsed into the left atrium. Congestive heart failure (CHF) was treated with an angiotensin converting enzyme (ACE) inhibitor and diuretic. An anti-mucolytic agent was prescribed as a symptomatic treatmentfor the coughing that could be due to mild bronchitis. Dog did not response well with treatment as the frequency of cough was not reduced and the duration was longer each time. Pimobendan was then added on to the initial treatment and there was a tremendous improvement seen from the patient after that. Episodes of productive cough were noticed greatly reduced and dog was much more active at home post two weeks of ACE inhibitor, diuretic and dual-acting inodilator. We successfully maintained the dog with minimal coughing episodes. However, the prognosis is moderate to poor in this case due to possibilities of refraction towards medications.

    This report describes the complications of obstructive urolithiasis in the lower urinary tract causing urinary bladder rupture in a Jamnapari buck. A 3-year-old Jamnapari buck was presented with the complaint of stranguria, subsequent anuria and a progressively distended abdomen for the past three days. Upon physical examination, body temperature, pulse rate and respiration rate were increased. Uroliths could be felt within the urethra in the ventral abdomen region. A urolith was removed via amputationof the urethral process, but the patency of the urethra could not be established. Transabdominal ultrasound revealed anechoic areas around the bladder, and the bladder was relatively small for a urinary obstructed goat. The bladder wall was thickened and shadow of sludge was observed within the bladder. Abdominocentesis was done and fluid analysis revealed that it was a haemorrhagic effusion. Blood results revealed renal disease, liver disease, muscle injury and haemoconcentration. Retrograde cystourethrogram revealed no urolithswithinthe urethra but there was leakage of the contrast agent from the bladder into the peritoneal cavity. The final diagnosis was complete blockage of the lower urinary tract leading to bladder rupture. Exploratory laparotomy was done and emergency cystorraphy was planned. Due to the poor condition of the urinary bladder with presence of septic peritonitis, the goat was euthanised.

    Old intact male dogs are often predisposed to benign prostatic hyperplasia. Both hypertrophy and hyperplasia of prostate
    gland occur due to hormonal influences. Clinical signs such as haematuria, stranguria and tenesmus are often associated with benign
    prostatic hyperplasia. A seven year-old local breed intact male dog was presented with a primary complaint of haematuria and
    stranguria. Diagnostic work-up conducted inclusive of complete blood count, serum biochemistry, urinalysis, abdominal radiograph,
    cystourethrography and abdominal ultrasonography. The dog was diagnosed with cystic benign prostatic hyperplasia. Prostatic
    omentalisation and castration were performed in this case.

    Hyperadrenocorticism is the excessive production of cortisol by the adrenal cortex. 15-20% of hyperadrenocorticism in dogs may be due to functional adrenal tumour. Here we present a case of functional adrenal tumour in a 10 years old Shih-Tzu Poodle mixed-breed dog that was presented to University Veterinary Hospital, Universiti Putra Malaysia. Physical examination findings include multiple cutaneous myiasis, a pendulous abdomen with comedones on the ventral thoracic region and thinning of the skin. Clinical signs shown were polyuria, polydipsia and polyphagia. Serum biochemistry result showed elevated alkaline phosphatase enzyme of 5 folds. Urinary specific gravity was minimally concentrated (1.015). Radiography showed generalised hepatomegaly. Meanwhile, ultrasonography showed unilateral enlargement of the right adrenal gland with mineralisation. Invasion of the right adrenal gland into the caudal vena cava was observed. A differentiation test (high-dose dexamethasone suppression test) was performed and a lack of suppression of the cortisol level was observed. Based on the appropriate clinical signs and physical examination findings, elevated alkaline phosphatase enzyme, minimally concentrated urinary specific gravity, generalised hepatomegaly, unilateral adrenal gland enlargement, and high-dose dexamethasone suppression test, a diagnosis of functional adrenal tumour was made.

    Osteoarthritis (OA) is a progressive joint disease leading to the destruction of joint structures, which in turn causes severe and chronic pain to the patient. Since OA is a troubling and disruptive disease, numerous researches have been done into diagnosing this disease, both in the early and the late stages of the disease. Diagnostic modalities such as radiography, computed-tomography (CT), micro-computed tomography (µ-CT), and magnetic resonance imaging (MRI) have been used in OA research. Not only that, more advance measurements and criteria have been established to standardize OA research. Currently, the OA research has been delving into proteomic studies to search for potential disease biomarkers. Biomarkers such as urinary C-terminal telopeptide of collagen type 2 (uCTX-II) and cartilage oligometric protein (COMP) have shown potential to be both diagnostic and prognostic biomarkers. For this review paper, the developments in diagnostic modalities are discussed focusing more on proteomic and biomarker studies.

    Leptospirosis is recognised as one of the leading zoonotic diseases and rodents have been implicated as one of the natural reservoirs of the disease. The Malayan porcupines (Hystrix brachyura) which are also a rodent could possibly be a carrier of leptospiral organisms. This study was conducted to determine the serological prevalence of leptospiral infection among captive Malayan porcupines and to disclose the possibility of porcupines as a reservoir for leptospiral infection. Fifty serum samples were obtained from the Malayan porcupines kept in captivity at the Wildlife Conservation Centre, Sungai Dusun, Malaysia. The microscopic agglutination test (MAT) was performed on the serum samples to detect the presence of agglutinating antibodies to a panel of 16 Leptospira serovars (Australis, Autumnalis, Ballum, Bataviae, Canicola, Celledoni, Djasiman, Hardjobovis, Hardjopratjino, Hebdomadis, Hurstbridge, Icterohaemorrhagiae, Javanica, Pomona, Pyrogenes and Sejroe). From the serological test, 18% (n=9/50) of the Malayan porcupines tested had leptospiral antibodies to serovars Javanica (8%), Hurstbridge (4%), Ballum (2%), Celledoni (2%) and Hardjoprajitno (2%). It is seen that this study disclosed a high prevalence of leptospiral infection in the Malayan porcupines tested and indicated that the Malayan porcupines could possibly be a source of leptospirosis to other animals including humans and that they might play an important role in the epidemiology of leptospiral infection in the country.

    The livestock industry has been relying merely on chemically synthesized antibiotic for eye infections as sprays and ointment. A natural remedy from Curcuma spp. has been tested for efficacy in curing keratoconjunctivitis and uveitis. A severe case of uveitis has been cured within 7 days, with impaired vision restored. These results are observations of a preliminary study conducted in a goat with uveitis.

    Bacteriological isolation and identification were performed on 60 cloacal swabs and 15 aquarium water samples of pet red-eared sliders (Trachemys scripta elegans) obtained from aquarium shops in the Klang Valley, Central Peninsula Malaysia. The most common bacteria isolated was Aeromonas spp., which was present in both cloacal swabs (70%) and aquarium water (86.7%). Klebsiella spp. (50%), Escherichia coli (33.3%), Yersinia spp. (16.7%) and Salmonella spp. (15%) obtained form cloacal swabs were identified as pathogenic to both humans and animals. Salmonella spp. were isolated from both cloacal swabs and aquarium water. The Salmonella serotypes identified were S. tennessee, S. typhimurium, S. brezany, S. pomona, S. corvallis and S. schwarzengrund. Bacterial infections in humans associated with handling exotic pets directly or indirectly in contact with aquarium water have been described regularly, hence the zoonotic significance of owning a turtle infected with Salmonella spp. or any pathogenic bacteria therefore cannot be ignored.

    Reptiles, which included snakes, chelonians (turtles, tortoises), iguanas and lizards, have been reported as important reservoirs
    for Salmonella. In Malaysia, reports on Salmonella in reptiles are not many. A search for works in Malaysia on salmonellae in
    reptiles found 28.0% chelonians, 27.5 - 61.0% snakes, 26.5 – 36.0% lizards and 31.0% house geckos carried Salmonella. The
    prevalence in some countries worldwide which included the United States of America, Brazil, Japan, Nigeria and few others were
    shown. The public health risk of the presence of salmonellae particularly in pet reptiles are discussed.

    Forty-eight canine mammary tumours (CMT) diagnosed at the Histopathology Laboratory, Faculty of Veterinary Medicine,
    Universiti Putra Malaysia, were reviewed retrospectively. Two control groups, one comprising all other cases involving female dogs
    and another group comprising only cases of neoplasia involving female dogs diagnosed in the laboratory over the same period of
    time were used for comparisons in this study. Fisher’s exact test and logistic regression were used to determine association between
    the factors and the risk of CMT. Thirty-nine (81.3%) of the tumours were diagnosed as adenocarcinoma, 8.3% (n=4) each, were the
    diagnoses for squamous cell carcinoma and mixed cell tumour. Adenoma had 2.1% (n=1). The prevalence of canine mammary gland
    tumours in this study is 39%. When CMT cases were compared with all other cases, significant association was observed with adult
    dogs (p = 0.032, logistic regression 0.012) and intact dogs (p = 0.009, logistic regression, 0.003). When CMT cases were compared
    with neoplasia cases, significant association was observed with pure breeds (p = 0.025) and intact dogs (p = 0.000034, logistic
    regression 0.00042). This study found that pure breed dogs, intact dogs and older dogs ( > 5years) have higher odds of having CMT
    in Malaysian dog population.

    An adult female Elephant Trunk Snake (Acrochordus javanicus) was reported to have been weak and inappetent for five days. The following morning the snake found dead, while in the process of shedding its skin. On post mortem examination, there were multiple circumscribed caseous nodules of various sizes distributed all over the liver, along the respiratory tract and on the lungs. Bacteriological analysis of the lungs and liver swab samples yielded Burkholderia pseudomallei, which was confirmed by PCR amplification of specific 16S rRNA. The condition was diagnosed as melioidosis and the organism was genotypically characterized as sequence type 51, a genotype that has been previously characterized in humans in Malaysia. Antibiotic susceptibility by both Disc diffusion or Kirby Bauer and E-test minimum inhibitory concentration (MIC) showed that the organism exhibited susceptibility to meropenem, imipenem, ceftazidime, cotrimoxazole and co-amoxyclav; the antibiotics recommended in the treatment of melioidosis.

    Cattle is one of an important maintenance hosts involved in the transmission of leptospirosis. Serological method is always implemented to detect current or past leptospiral infection in cattle. The results can be obtained immediately compared to isolation method which need more longer time. An in-house IgG enzyme-linked immunosorbent assay (ELISA) using heat-killed whole cells of local isolate Leptospira kmetyi serovar malaysia strain Bejo-Iso9 (ELISABejo-Iso9) was developed in this study. The perfomance of ELISA-Bejo-Iso9 was compared with in-house IgGELISA using reference strain 117123 (hardjo bovis) antigen (ELISA-117123) and CUSABIO® commercial ELISA. It was found that, the performance of ELISA-Bejo-Iso9 was promising to compete with commercial ELISA. The specificity and sensitivity was 98.75% and 53.75%, respectively. The sensitivity of ELISA-Bejo-Iso9 was lower than commercial ELISA. However, the specificity of ELISA-Bejo-Iso9 was higher than commercial ELISA. Due to economically and availability factors, this finding suggested that the ELISA-Bejo-Iso9 can be used as an alternatif method for serological diagnosis of leptospirosis in cattle.

    This study was designed to characterise the lameness cases in cattle reported to the University Veterinary Hospital (UVH) of
    Universiti Putra Malaysia (UPM), Serdang, Selangor. Medical records from 2013 to 2017 were reviewed and 136 cases of cattle
    diagnosed as lameness were retrieved. Information concerning signalment, location of lesions, and cause of lameness was analysed.
    Majority of the cases were reported in dairy (77%) compared with beef cattle (23%) with 73% being under semi-intensive
    management system. Foot lesions accounted for about 51% of cases, while lesions were more on the hindlimbs than the forelimbs

    Endurance horses continuously undergoing training. This will cause inflammation which leads to acute phase reaction with the production of acute phase protein, especially serum amyloid A (SAA). The purpose of this study was to establish concentration of SAA in normal endurance horses in the blood serum using two-site enzyme linked immunoassay (ELISA) technique. Horse sera were aliquoted from blood taken from jugular venipuncture. The highest concentration of SAA was observed in horses rested between 12 months and 24 months. The lowest concentration of SAA was noticed in horses rested more than 24 months. All the horses between 6 and 11 years old have high SAA concentration. When resting intervals were compared against gender of the horses, it was noted that all mares have high SAA concentration compared to gelding and stallion. Whereas SAA concentration in Thoroughbred horses were high compared to Arabian horses in all rest intervals. The SAA concentration in horses rested more than 24 months was low most probably because the horses recovered well from the inflammatory process happened during the endurance race.

    A 5-year-old Mongrel was brought presented with the complaint of having serosanguineous discharge from penis for a month since adoption. Physical examination revealed cauliflower-like mass at the bulbus glandis. Presence of numerous anisokaryotic and anisocytotic round to oval histiocytes with multivacuolated cytoplasm from cytology, an evidence of canine transmissibale venereal tumour (CTVT). The mass was successfully surgically resected using electrocautery and was in remission for 12 months (since January 2019).

    A 6-year-old intact Persian cat was presented for the primary complaint of inappetence and weight loss. Irregular surface of
    kidneys was palpated during physical examination. Abdominal radiograph findings were indicative of renomegaly. Ultrasonography
    revealed multiple anaechoic structures within the renal parenchyma. The cortex, medulla and renal pelvis were unable to be
    differentiated. Both radiographic and ultrasonographic findings were suggestive of polycystic kidney disease. Blood test revealed
    normochromic, normocytic anaemia with azotaemia whereas urinalysis findings were hypostenuria and proteinuria, consistent of
    chronic kidney disease due to polycystic kidney. Ultrasound is a useful antemortem diagnostic tool to diagnose polycystic kidney
    disease in cats.

    Avian polyomavirus disease is among the most common viral diseases of domesticated exotic birds as such in psittacine families. Caused by avian polyomavirus (APV) which possess a circular, double-stranded DNA which encodes for major structural virus protein 1 (VP1) and minor structural proteins VP2, VP3 and VP4, the disease is also known as Budgerigar fledgling disease polyomavirus (BFPyV), Papovavirus, and Psittacine polyomavirus. Infections from APV may lead to cutaneous haemorrhage, abdominal distension, feather abnormalities and even death. The APV virus has a broad avian host range and is known to cause acute chronic disease in several psittacine birds such as parrot, cockatoo, macaw, and budgerigar. The current status of APV epidemiology globally has not been fully recorded. Only the studies of the virus and disease caused within several countries are used as references, and few were done together with detection of beak and feather disease virus. Despite the common occurrence of APV among bird breeders in Malaysia, a very limited study has been done to evaluate the prevalence status of APV in Malaysia. In this review, we wish to disseminate knowledge, particularly to pet owners and bird breeders, on APV characterisations, its updated occurrence worldwide and prevention strategies. This information may be useful to trigger in depth study on the epidemiology of disease and better management practises among breeders.
