Histopathology of protozoal infection in animals: a retrospective study at the University of Philippines College of Veterinary Medicine (1972-2010).

The authors describe the first parasitological survey of protozoal infections on tissue slide sections of field cases processed at the histopathology laboratory of the College of Veterinary Medicine (CVM) at the University of the Philippines Los Baños (UPLB). Over 80% of the field cases were from Region 4 (CALABARZON) and the rest were equally distributed from other areas of the Philippines, namely: Region 2 (Cagayan Valley), Metropolitan Manila (National Capital Region), Region III (Central Luzon) and Region VI (Western Visayas). Histopathological analyses of tissue sections from 51 archived cases (1972-2010) of parasitic aetiology were performed.

Complete coding sequence, sequence analysis and transmembrane topology modelling of Trypanosoma brucei rhodesiense putative oligosaccharyl transferase (TbOST II).

The partial nucleotide sequence of putative Trypanosoma brucei rhodesiense oligosaccharyl transferase gene was previously reported. Here, we describe the determination of its full-length nucleotide sequence by Inverse PCR (IPCR), subsequent biological sequence analysis and transmembrane topology modelling. The full-length DNA sequence has an Open Reading Frame (ORF) of 2406 bp and encodes a polypeptide of 801 amino acid residues.
