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.

An adult female dog was presented for evaluation of mammary gland masses. Complete blood count and serum chemistry data were within normal limits. Fine-needle aspiration cytology of the mammary masses revealed clusters of malignant epithelial cells with clear cytoplasmic vacuoles. Based on histopathological findings, a diagnosis of lipid-rich mammary carcinoma was made. Approximately 5 weeks after surgical removal, the tumor recurred at the surgery site and metastasis to the tibia was detected. Due to the poor prognosis and deterioration of the condition, the dog was euthanized.

Sixty five dogs belonging to five different breeds were subjected to dog erythrocyte antigen 1.1 test to assess the occurrence of dog erythrocyte antigen 1.1 in Kerala state, India. Of the animals tested 51 were found positive for the antigen with considerable variation across breeds. Results of the present study indicate that the expression of DEA 1.1 in the Indian canine population may at the higher end of the international prevalence.

Limited information is available regarding gastro-intestinal (GI)parasitic infections in Malaysian swine populations. Hence, the present study aims to determine the prevalence of GI parasites in two swine populations in Malaysia, using formalin-ether concentration technique. In the present study, three helminths and two protozoa were detected in 91 swine rectal fecal samples. The zoonotic transmissible protozoan, Balantidium coli (22.0%) had the highest infection rate, followed by strongyle (4.4%), Entamoeba spp. (2.2%), Fasciolopsis spp. (1.1%) and Trichuris suis (1.1%). The co-infection between T. suis and B. coli was also found in this study.

Edible bird's nest (EBN)is made from the saliva of swiftlet from the Aerodramus species. It is one of the most widely consumed traditional health food by the Chinese community due to its claimed medicinal value. EBN contains glycoproteins with abundance of sialic acid (SA). EBN with higher SA content has a potential to command for higher price. The objective of this study was to determine and compare free SA content of EBN collected from Johor and Kelantan. A total of 23 and 30 of raw and unprocessed EBN samples were obtained from Kelantan and Johor, respectively. SA from EBN samples were analysed using LC-MS/MS. Johor showed higher content of free SA with the value of 135.04 ± 29.60 mg/kg compared to Kelantan which has a value of 95.55 ± 25.6 mg/kg. Highest content of free SA was found in EBN from Pontian district, Johor.

A total of five species of the nematodes, Acuaria spiralis, Gonyglonema ingluvicola, Ascaridia galli, Heterakis gallinarum and Oxyspirura mansoni were recovered from the Malaysia domestic chicken, Gallus domesticus and studied for their morphology. Scanning electron microscopy was used to study and observe the outer surface of the nematodes. The morphological of the five species ofnematodes were described and compared.

Avian haemoparasites are known to exert negative pressures on theirhosts causing considerable pathology and mortalities. The present study reports on the prevalence of haemoprotozoa and microfilaria in various species of wild birds and domestic poultry in Selangor, Malaysia, and contributes to the database on the occurrence of thesepathogens among avifauna in the country. Giemsa-stained thin blood smears were screened from 728 birds representing five avian orders, namely Galliformes, Anseriformes, Phoenicopteriformes, Pelecaniformes and Gruiformes. The most common haemoparasite was Plasmodium, with a prevalence of 8.0%. The aquatic/wetland species of birds (Anseriformes and Gruiformes) were the most common hosts for this pathogen with high infection rates (31.8% – 50.0%). The prevalence of Plasmodium in domestic poultry was moderate (2.7%). Leucocytozoon sabrazesi and L. caulleryi were confined to the Galliformes with relatively low average infection rates of 0.7% and 0.5%, respectively. Haemoproteus was detected for the first time in domestic poultry and Red Jungle fowls in the country, with anaverage prevalence of 0.8%. Trypanosomes and microfilaria were only present in the village chickens and Red Jungle fowls, with high microfilaraemia rates (19.0%) in the latter. The current compilation will contribute to our understanding on avianhaemoparasite transmission in the country.
