Vaccination of squirrel monkeys (Saimiri spp.) with nanoparticle-based Toxoplasma gondii antigens: new hope for captive susceptible species.

Squirrel monkeys (Saimiri spp.), new world primates from South America, are very susceptible to toxoplasmosis. Numerous outbreaks of fatal toxoplasmosis in zoos have been identified around the world, resulting in acute respiratory distress and sudden death.

Cryopreservation of Giraffe Epidydimal Spermatozoa Using Different Extenders and Cryoprotectants.

Giraffe numbers have plummeted over the last 30 years by 30-40%. Thus, their conservation status has been raised from least concern to vulnerable. Efforts to manage in situ and ex situ populations are increasing.

Constitutive IFNα Protein Production in Bats.

Bats are the only mammals with self-powered flight and account for 20% of all extant mammalian diversity. In addition, they harbor many emerging and reemerging viruses, including multiple coronaviruses, several of which are highly pathogenic in other mammals, but cause no disease in bats. How this symbiotic relationship between bats and viruses exists is not yet fully understood.

Evidence for the existence of a new genus Chlamydiifrater gen. nov. inside the family Chlamydiaceae with two new species isolated from flamingo (Phoenicopterus roseus): Chlamydiifrater phoenicopteri sp. nov. and Chlamydiifrater volucris sp. nov.

The family Chlamydiaceae currently comprises a single genus Chlamydia, with 11 validly published species and seven more taxa. It includes the human pathogens Chlamydia (C.) trachomatis, C.

Inflammatory and oxidative status in European captive black rhinoceroses: A link with Iron Overload Disorder?

Iron Overload Disorder (IOD) is a syndrome developed by captive browsing rhinoceroses like black rhinoceroses (Diceros bicornis), in which hemosiderosis develops in vital organs while free iron accumulates in the body, potentially predisposing to various secondary diseases. Captive grazing species like white rhinoceroses (Ceratotherium simum) do not seem to be affected. The authors hypothesized that inflammation and oxidative stress may be implicated in the pathogenesis of IOD in captive black rhinoceroses, making this syndrome a potential common denominator to various diseases described in captivity in this species.

[Evaluation of efficacy and safety of hypertension treatment with original angiotensin-converting enzyme inhibitors: the comparison of original and generic formulations].

Unlabelled: The hypertension is a civilization disease, slowly destroying the cardio-vascular system and leading to serious complications, which may result in patient death. Critical factors enhancing the proper functioning of the body are: properly selected pharmacotherapy and the self-control of the blood pressure.

The Aim Of This Study: was to evaluate the effectiveness and safety of the hypertension treatment with generic and original formulations of angiotensin converting enzyme (ACE) inhibitors.

Successful treatment of a congenital pulmonic valvular stenosis in a snow leopard (Uncia uncia) by percutaneous balloon valvuloplasty.

A 3-yr-old intact female snow leopard (Uncia uncia) was evaluated for progressive apathy, lethargy, and decreased appetite. Cardiac auscultation revealed a left basal grade IV/VI systolic ejection murmur, and an echocardiogram confirmed a severe pulmonic valvular stenosis (pressure gradient of 98 mm Hg). The lesion was managed by balloon valvuloplasty, resulting in a marked pressure gradient reduction (30 mm Hg).

Treatment of a retroperitoneal abscess by omentalization in an orangutan (Pongo pygmaeus pygmaeus).

A 38-yr-old orangutan (Pongo pygmaeus pygmaeus) presented with chronic lethargy and difficulty in locomotion that progressed to weakness, anorexia, and permanent dorsal and/or lateral recumbency. The orangutan was immobilized with ketamine. Abdominal ultrasonography revealed a mass in the caudal portion of the abdomen.
