In this study, we describe a case of epitheliogenesis imperfecta (EI) observed in the fetus of Korean native cattle. The fetus had multifocal areas of skin defect, especially on the distal portions of the four limbs, and the affected areas were bright-red and glistening. Histopathologically, these areas were characterized by complete absence of squamous epithelium, infiltration of inflammatory cells into the dermis, atrophy of hair follicles, sebaceous and sweat glands. To the best of our knowledge, this is the first report of epitheliogenesis imperfecta in Korean native cattle.

Im, J.E., Konkuk University, Seoul, Republic of Korea | Yoon, H.Y., Konkuk University, Seoul, Republic of Korea | Kim, S.G., Konkuk University, Seoul, Republic of Korea | Lee, C.M., Konkuk University, Seoul, Republic of Korea | Eom, K.D., Konkuk University, Seoul, Republic of Korea | Park, H.M., Konkuk University, Seoul, Republic of Korea
A 10-year-old castrated male papillon presented with nasal discharge, coughing and chronic dysphagia. On physical examination, the dog exhibited sneezing, gurgling and movement of the throat with repeated attempts to swallow fluids. A diagnosis of cricopharyngeal achalasia (CPA) was made based on video fluoroscopic demonstration of failure of relaxation of the upper esophageal sphincter. This report describes the diagnosis of CPA in an old dog, which is rarely diagnosed in older animals.

The aim of this study was to test the potential diagnostic usefulness of recombinant Toxoplasma gondii SAG1 antigen and
excretory-secretory antigen (ESA), with respect to toxoplasmosis detection and infection phase distinction in laboratory mouse by determining specifi c serum IgM and IgG antibodies with the use of indirect ELISA technique. The highest titre at the beginning of infection was demonstrated by immunoglobulin M while the highest titre at the end of the infection was displayed by immunoglobulin G. In contrast, sera of chronically infected mice, positive IgG titre was detected on day 14 p.i. for ESA or day seven p.i. with rSAG1 and increased thereafter until day 70 p.i. after which the titre stabilized. IgA antibody also showed similar kinetics as IgG. Potentially rSAG1 may be a suitable diagnostic antigen than ESA in the diagnosis of acute and chronic toxoplasmosis.

Chandrawathani P. | Faizal H. | Erwanas A. I. | Lily Rozita | Jamnah O. | Ramlan M. | Premaalatha B.
The Malaysian Pangolin (Manis javanica) is an endangered species,
but is widely hunted for its medicinal value in body parts. A total of sixteen pangolins were screened for blood protozoa and six
pangolins were confi rmed to be positive for eperythrozoonosis infection based on morphology from blood smears stained with 8% Giemsa. The causative organism, Eperythrozoon sp., with a size of 0.3 μm were observed under a compound microscope at 100× magnification on the surface of red blood cells as blue coloured dots. This is the fi rst report of Eperythrozoon infection from pangolins in Malaysia. Further identifi cation using polymerase chain reaction (PCR) is necessary to confi rm E. ovis or wenyonii,
which is uncultivatable in artifi cial media.

2014
Shawaluddin T. | Zahariah I. | Mardhati M. | Norliza S. | Mohd Suria A. Y. | Wong H. K.
In vitro digestibility study was conducted to determine the effectsof supplementing fractionated Refined,Bleached and Deodorized Palm Stearin(RBDPST) on ruminal digestion. Fractionated RBDPST was soaked in incubation medium consisting of distilled water, buffer solution, trace element solution, micro and macro mineral solution, as well as rumen liquor that was collected from slaughtered cattle. This experiment was conducted at 39°C with an incubation period of 24 hours. Dried napier grass was used as control treatment. Gas producedwas recorded and collected to measure the methane gas produced. Methane gas produced from fractionated RBDPST was found to be relatively lower than control. This indicates that fractionated RBDPST had the ability to function as rumen bypass fat as it was not fully digested in the rumen.

Antiviral effect of crude aqueous extracts of Neem leaves and Neem bark (Azadirachta indica) belonging to the family Meliaceae againstvelogenic Newcastle Disease virus was studied. Maximum non- toxic dose and determination of antiviral activity by in vitro and in vivo virus inhibition assay was carried out using embryonated SPF chicken eggs and SPF chickens. Different concentration content of the aqueous neem extract from branches of neem tree storing at 4°C reacted against velogenic ND virus was conducted. Determination of antiviral activity by in vivo assay in SPF chickens was compared to the group of untreated with Neem extract.

2014
Lily Rozita M. H. | Premaalatha, B. | Jamnah O. | Chandrawathani P. | Thongsahuan, S. | Ramlan M. | Erwanas, A. I | Chethanond, U.
The faecal egg count reduction test (FECRT) was conducted on local goats in a smallholder farm on the outskirts of Ipoh. Levamisole drug tested for resistance against strongyles, was administered orally at the rate of 10 mg/kg body weight. Results showed that thestrongyle worm population was resistant to levamisole. The percentage reduction was 75% and lower confidence limit less than 90%. The worm population was made up mainly of Haemonchus contortus(71%), followed by Oesophagostomum sp.(18%) and Trichostrongylus sp. (11%). This finding indicates that anthelmintic resistance is an existing problem in Malaysia, even on a small farm. Alternativeapproaches to chemical anthelmintics have been recommended to controlnematodes in goats such as improved grazing management, herbal medication or biological control, to delay the occurrence of chemical resistance and prevent severe helminth infections in goat flocks.

A case of a cestode parasite (Choanotaenia infundibulum) egg wasfound in the intestine of chicken which was sent to the Veterinary Research Institute, Ipoh in February 2014 for post-mortem. Other parasites found in the intestine were adult tapeworm and oocyst ofcoccidia. The examination of the chicken intestine for helminth ova was undertaken using direct examination of a simple wet smear of the intestinal content which was observed under compound microscope.The cestode parasite was identified based on helminthological keys by Soulsby, 1982.

Venugopal, Syam K. | Anoop, S. | Saragom, Sherin B. | Philip, Susannah Bijee | Prakash, Sharanya | Joy, Bini | Kankonkar, Ashay P.
The reports on wing bone fractures are common in avian species, butare scanty with peafowl. An Indian peahen (Pavo cristatus) was presented with a wounded unstable left wing and inability to fly. Crepitus could be felt on palpation and the radiographic examination showed an open, transverse, mid-diaphyseal fracture of humerus. Open reduction, internal fi xation and wound closure were performed under general anaesthesia followed by external coaptation of the operated wing. Post-operative antibiotics and analgesics were administered. Bythird week, clinical signs of healing were noticed and physical therapy was advised.The bird recovered uneventfully and was released. A unique case on management of transverse humerus fracture rarely reported in peafowl is documented.

Blastocystis is considered to be a zoonoses and it is believed that animals such as chicken constitute large reservoirs for human infection via the faecal-oral route. Therefore, Blastocystis infection was surveyed in free-range chicken and cage reared chicken comprising broiler birds for consumption as well as jungle fowls andsilkie chicken kept for recreation. Fresh faecal samples collected were examined by wet smear preparation and were cultured in Jones medium supplemented with 10% horse serum. Out of 107 chickens, it was found that most of the free-range chicken was positive for Blastocystis sp. with a high prevalence rate of 80%–100% in village chicken, jungle fowl and white silkie chicken. However, the cage-reared chicken, consisting of broiler chicken had no infection. The vacuolar form was the most common Blastocystis cell form found in cultures, similar to B. hominis.These cells were usually spherical and vary greatly in size, ranging from 10 μm to 30 μm in diameter. Owing to the free ranging and scavenging habits, the likelihood of acquiring the infection fromthe environment contaminated with the faecal material of animals with Blastocystis is high in free-range chicken as compared to caged chicken.
