Zootaxa, 2019 The long-tailed parakeets of the genus Psittacula Cuvier, 1800 have thus far been regarded as a homogeneous and monophyletic group of parrots. We used nucleotide sequences of two genetic markers (mitochondrial CYTB, nuclear RAG-1) to reconstruct the phylogenetic relationships of Psittacula and closely related species.

Pathological studies on chlamydiosis in parakeets (Psittacula krameri manillensis)
Avian Pathology, 1990Histological, immunohistochemical and ultrastructural findings are described in 20 parakeets (Psittacula krameri ntanillensis) affected with chlamydiosis. The main histological lesions consisted of focal necrosis in the liver and adrenal gland, lymphocytic depletion with fibrin exudation in the splenic sinuses and follicles and fibrinopurulent ...

Islets of Langerhans in the parakeet, Psittacula krameri.
Anatomischer Anzeiger, 1980The pancreatic gland of Psittacula krameri is divisible into 4 lobes i.e. dorsal, ventral, third and splenic. The endocrine part is composed of alpha 1-, alpha 2- and beta-cells. The islets are of 4 kinds viz., alpha islets (having alpha 1- and alpha 2-cells), beta islets (having beta- and alpha 1-cells), pure beta islets (consisting of beta-cells ...
