Genetic characterization of the oxytocin-neurophysin I gene (OXT) and its regulatory regions analysis in domestic Old and New World camelids

AbstractA species of Sarcocystis is reported from a naturally infected African grey parrot, Psittacus erithacus, from Costa Rica. Only mature sarcocysts, measuring up to 2 mm in length and up to 750 μm in width, were observed. The sarcocyst wall was smooth. The villar protrusions on the sarcocyst wall were up to 5 μm long and up to 1.1 μm wide; they were folded over the sarcocyst wall giving a thin-walled appearance. The microtubules in villar protrusions were smooth and confined to villar protrusions. Bradyzoites in sections were 5.4–6.6 × 1.3–2.0 μm in size. Sequencing the small subunit and first internal transcribed spacer portions of ribosomal DNA related this parasite to, but distinguished it from, previously characterized species of Sarcocystis that encyst in the musculature of birds and complete their sexual development in New World opossums of the genus Didelphis. This evidence suggests that the parrot may have acquired its infection from an opossum from which it suffered a debilitating attack a year prior to the onset of depression, anorexia, and ultimately death.

AbstractPterygodermatites (Paucipectines) zygodontomis, a nematode parasite of the small intestine of the rodent Necromys lasiurus, from Uberlândia, Minas Gerais state, Brazil, was analysed by light and scanning electron microscopy. Additionally, phylogenies were inferred from the mitochondrially encoded cytochrome c oxidase I gene (MT-CO1). Details of the helminth surface, such as the oral aperture, cephalic papillae, papillae in the posterior region of the body and longitudinal cuticular elements represented by spine-like projections and fans are presented, adding new taxonomic details. Molecular phylogenetic analysis, based on the MT-CO1, demonstrated that P. (P.) zygodontomis and Pterygodermatites (Paucipectines) jaegerskioldi form a unique evolutionary unit in accordance with the subgenus Paucipectines and corroborated their occurrence in cricetid and didelphid hosts.

The genetic polymorphism of the CSN1S1 (casein alpha-S1) locus was investigated in two endangered Czech goat breeds (White Shorthair and Brown Shorthair). These breeds are kept mainly for their good dairy performance. Genetic characterization of the CSN1S1 locus contributes to the knowledge of the genetic structure of these two endangered breeds. The study was performed on 498 goats (333 White and 165 Brown Shorthair goats) by means of different polymerase chain reactions (PCR). We detected A* (associated with normal content of protein), E, F and 01 alleles. The analysis showed a prevalence of CSN1S1 F (0.658; 0.597) and CSN1S1 A* (0.269; 0.303) alleles. In both breeds, the frequency of occurrence of E and 01 alleles was very low: E (0.054; 0.085) and 01 (0.019; 0.015), respectively. No population followed the Hardy-Weinberg equilibrium, the value of polymorphic information content (PIC) being 0.426 in White and 0.472 in Brown Shorthair goats. Moreover, the test of population differences (P = 0.130) showed no significant differences between White and Brown Shorthair goats. This genetic peculiarity makes the preservation of the population of both breeds worthwhile.

First Time

Tick-borne encephalitis virus (TBEV) was isolated for the first time in Sweden in 1958 (from ticks and from 1 tick-borne encephalitis [TBE] patient).1 In 2003, Haglund and colleagues reported the isolation and antigenic and genetic characterization of 14 TBEV strains from Swedish patients (samples collected 1991–1994).2 The first serum sample, from which TBEV was isolated, was obtained 2–10 days after onset of disease and found to be negative for anti-TBEV immunoglobulin M (IgM) by enzyme-linked immunosorbent assay (ELISA), whereas TBEV-specific IgM (and TBEV-specific immunoglobulin G/cerebrospinal fluid [IgG/CSF] activity) was demonstrated in later serum samples taken during the second phase of the disease.
