BACKGROUND: Spermatozoa are stored in the oviductal functional sperm reservoir in animals with internal fertilization, including zoologically distant classes such as pigs or poultry. They are held fertile in the reservoir for times ranging from a couple of days (in pigs), to several weeks (in chickens), before they are gradually released to fertilize the newly ovulated eggs. It is currently unknown whether females from these species share conserved mechanisms to tolerate such a lengthy presence of immunologically-foreign spermatozoa...

This study was performed to provide information on Tricholipeurus balanicus (Werneck 1938) detected on slender-horned gazelles (Gazella leptoceros) (Cuvier 1842). Four slender-horned gazelles kept in the El Hamma Zoological Garden in Algeria were examined for lice in April 2015. Three of the four gazelles were infested with lice; of 37 lice collected from the infested animals, 14 were females, 16 were males, and 7 were nymphs. Lice were mainly found on the back and hind legs of the gazelles. The lice were collected by a forceps, preserved in 70% alcohol, and cleared in 10% KOH for 24 h...

The sulcata or African spurred tortoise (Centrochelys sulcata) is a large tortoise species that is commonly kept in zoologic collections and as a pet. The objectives of this study were to establish reference intervals for selected biochemical analytes in clinically healthy captive sulcata tortoises and to evaluate the impact of blood sampling site and sex. Blood samples were collected from 60 tortoises from either the dorsal coccygeal (tail) vein or the subcarapacial venous plexus based on their body size. The packed cell volume and refractometric total solids (TS) were determined...

The domestic animals descend from various wild ancestors. Thus, for example, of the wolf, the dog (15  000 BC), of the Bezoar goat the goat (10  000 BC), of the Asian mouflon the sheep (10  000 BC), of the wild boar the pig (8000 BC) and of the aurochs the cattle (7000 BC). Domestication has dramatically changed our culture and led to a great diversity of animal breeds. This is a unique cultural and historical treasure, which we have to preserve for future generations. The zoological park Arc Warder is Europe's largest center for rare and endangered domestic animal breeds...

A reproductive analysis of a captive group of jaguars (Panthera onca; n = 6) at the Santacruz Zoological Foundation in Cundinamarca, Colombia, was conducted by performing a longitudinal, noninvasive, hormonal analysis of estradiol and progestogens in females and of androgens in males. During four seasons, female jaguars confined in solitary were evaluated for ovarian activity and spontaneous ovulation, male jaguars for testicular activity. A second hormonal follow-up was conducted in the females after administration of gonadotropins...

The identity of Metochus abbreviatus Scott, 1874 (Hemiptera: Heteroptera: Rhyparochromidae: Rhyparochrominae: Rhyparochromini) is clarified based on reexamination of the lectotype. The subjective synonymy of Dieuches kreyenbergi Breddin, 1906 with M. abbreviatus is confirmed. The following new subjective synonymies are proposed: Rhyparochromus erosus Walker, 1872 = Metochus abbreviatus Scott, 1874, syn. nov. = Metochus holsti Distant, 1918, syn. nov. Bibliographies of the names are provided and it is demonstrated that the name M...

The following scale insect specific names need gender changes to agree with their genus group names in the current printed catalogues and in ScaleNet, a database of the scale insects (García Morales et al. 2016). This action is taken to agree with Article 31.2 of the International Code of Zoological Nomenclature (International Commission on Zoological Nomenclature 1999).

The presence of complex geographic variation among species allied to the absence of clear morphological breaks among populations has led to many poorly defined taxa in the genus Pyrrhura (Psittacidae: Arinae: Arini). This article addresses nomenclature of the Pyrrhura picta species complex, particularly the identity of three little-known names introduced by Miranda-Ribeiro (1926): Pyrrhura luciani ochrotis, P. l. pallescens and P. l. melanoides. We show that these names represent subjective synonyms of Pyrrhura snethlageae Joseph & Bates, 2002...

In my revision of the genus Pselaphomorphus Motschulsky, 1855 (Vásquez-Vélez 2016) the depository of the holotype of P. cayennensis Vásquez-Vélez, 2016 was not listed. As a result, the requirements of Article 16.4.2 of the International Code of Zoological Nomenclature (International Commission on Zoological Nomenclature 1999) have not been met, making the name unavailable. This note aims at correcting the earlier mistake: the holotype of P. cayennensis is deposited at the Museum of natural history (Muséum d'histoire naturelle), Geneva, Switzerland...

Toxoplasmosis is an infectious, zoonotic and parasitic disease, caused by Toxoplasma gondii. In this manucript, two cases of infection with T. gondii in captive animals from a zoological park in the central region of Chile are described. One case was a red kangaroo (Macropus rufus), which is highly susceptible to the infection, and the other was a Patagonian mara (Dolichotis patagonum), a rodent in which there is no previous report of the infection. Both animals had myocarditis, with the presence of intralesional tachizoites and cysts suggestive of infection with T...

BACKGROUND: The Southern Stingray (Dasyatis americana) is a batoid elasmobranch frequently exhibited in zoological institutions. Blood is commonly collected from the caudal hemal arch at the tail base in stingrays for the purpose of health assessment and clinical pathology tests. An alternative site that allows a dorsal or ventral approach without necessitating puncture of a cartilaginous structure has been identified between the cartilaginous pectoral fin rays (ceratotrichia). OBJECTIVES: The purpose of the study was to compare CBC, plasma biochemistry analytes, and blood gas variables between blood samples collected from the caudal and pectoral fin vasculature sites of the Southern Stingray...

Acellular extrinsic fiber cementum is a mineralized tissue that covers the cervical half of the tooth root surface. It contains mainly extrinsic or Sharpey's fibers that run perpendicular to the root surface to anchor the tooth via the periodontal ligament. Acellular cementum is continuously and slowly produced throughout life and exhibits an alternating bright and dark pattern under light microscopy. However, although a better understanding of the structural background of acellular cementum is relevant to many fields, such as cementochronology, periodontology and tissue engineering, acellular cementum remains rarely studied and poorly understood...
