Cryptorchidism in free-living jaguar (): first case report.

Anim Reprod 2020 Nov 24;17(4):e20200555. Epub 2020 Nov 24.

Instituto Reprocon, Campo Grande, MS, Brasil.

Cryptorchidism is a genital alteration wherein one or both testicles fail to descend into the scrotum and has multifactorial causes. A free-range adult male was captured twice in the Pantanal of Nhecolândia to put a GPS collar and semen collection. Pharmacological semen collection, andrological examination and semen analysis were performed. Read More

Adult and yearling pampas deer stags () display mild reproductive seasonal patterns with maximum values in autumn.

Anim Reprod 2020 Jun 29;17(2):e20200021. Epub 2020 Jun 29.

Departamento de Biociencias Veterinarias, Facultad de Veterinaria, Universidad de la República, Montevideo, Uruguay.

The pampas deer is an endangered species, from which reproductive biology little is known. We aimed to describe and compare the reproductive seasonal patterns of adult and yearling pampas deer stags throughout the year, including morphological traits, testosterone concentration, sperm morphology and cryoresistance pattern changes. Six adult (AS) and five yearling (YS) stags were captured with anesthetic darts once in winter, spring, summer and autumn to study morphological variables, serum testosterone and semen. Read More

Genomic reaction norm models exploiting genotype × environment interaction on sexual precocity indicator traits in Nellore cattle.

Anim Genet 2020 Mar 15;51(2):210-223. Epub 2020 Jan 15.

School of Agricultural and Veterinarian Sciences, São Paulo State University (UNESP), Via de Acesso Prof. Paulo Donato Castelane, 14884-900, Jaboticabal, Brazil.

Brazilian beef cattle are raised predominantly on pasture in a wide range of environments. In this scenario, genotype by environment (G×E) interaction is an important source of phenotypic variation in the reproductive traits. Hence, the evaluation of G×E interactions for heifer's early pregnancy (HP) and scrotal circumference (SC) traits in Nellore cattle, belonging to three breeding programs, was carried out to determine the animal's sensitivity to the environmental conditions (EC).

D Creamer

Clin Exp Dermatol 2018 Oct 31;43(7):766-769. Epub 2018 May 31.

Department of Dermatology, King's College Hospital, London, UK.

During the Second World War, thousands of captured British and Commonwealth troops were interned in prisoner-of-war (POW) camps in the Far East. Imprisonment was extremely harsh, and prisoners developed multiple pathologies induced by physical hardship, tropical infections and starvation. Immediately after the war, several POW doctors published their clinical experiences, including reports of skin disease caused by malnutrition. Read More

High Arctic lemmings remain reproductively active under predator-induced elevated stress.

Oecologia 2018 07 12;187(3):657-666. Epub 2018 Apr 12.

Centre for the Neurobiology of Stress, Department of Biological Sciences, University of Toronto Scarborough, 1265 Military Trail, Toronto, ON, M1C 1A4, Canada.

Non-consumptive effects of predation have rarely been assessed in wildlife populations even though their impact could be as important as lethal effects. Reproduction of individuals is one of the most important demographic parameters that could be affected by predator-induced stress, which in turn can have important consequences on population dynamics. We studied non-consumptive effects of predation on the reproductive activity (i. Read More

Reproductive pattern of the large fruit-eating bat, Artibeus amplus (Chiroptera: Phyllostomidae) in the Venezuelan Andes.

Rev Biol Trop 2017 Mar;65(1):335-44

Bimodal polyestry is the most common reproductive pattern in tropical bats, and it consists in producing one offspring per female twice a year. Reproductive patterns are closely related to rainfall regimes, frequently occurring twice a year in tropical regions. The goal of our study was to determine the reproductive pattern of the large fruit-eating bat, Artibeus amplus Handley, 1987 in a cave in the Venezuelan Andes inhabited by a large, stable colony.

Diagnosing Testicular Torsion before Urological Consultation and Imaging: Validation of the TWIST Score.

J Urol 2016 06 2;195(6):1870-6. Epub 2016 Feb 2.

University of Texas Southwestern Medical Center, Dallas, Texas; Children's Health, Dallas, Texas. Electronic address:

Purpose: The TWIST (Testicular Workup for Ischemia and Suspected Torsion) score uses urological history and physical examination to assess risk of testis torsion. Parameters include testis swelling (2 points), hard testis (2), absent cremasteric reflex (1), nausea/vomiting (1) and high riding testis (1). While TWIST has been validated when scored by urologists, its diagnostic accuracy among nonurological providers is unknown. Read More

Structural study of gubernaculum testis in fetuses with prune belly syndrome.

J Urol 2015 May 6;193(5 Suppl):1830-6. Epub 2014 Oct 6.

Urogenital Research Unit, State University of Rio de Janeiro, Rio de Janeiro, Brazil. Electronic address:

Purpose: We compared and contrasted the structure of the gubernaculum testis in fetuses with prune belly syndrome and normal controls.

Materials And Methods: We studied a total of 6 gubernacula from 3 male fetuses with prune belly syndrome and a total of 14 from 7 male fetuses without an anomaly. Gubernacular specimens were cut into 5 μm sections and stained with Masson trichrome to quantify connective tissue and smooth muscle cells, with Weigert stain to observe elastic fibers and with picrosirius red with polarization to observe collagen.

J Wildl Dis 2010 Apr;46(2):433-41

Department of Biology, University of Utah, 257 South 1400 East, Salt Lake City, Utah 84112-0840, USA.

Sin Nombre virus (SNV), one of at least 45 hantaviruses described worldwide, is hosted by the deer mouse, Peromyscus maniculatus, a common species throughout most of North America. Herein, we describe general life-history characteristics of deer mice and the ways in which these factors relate to the incidence of SNV infections among populations of this host species in and around Portland, Oregon. In total, 3,175 deer mice were captured from October 2002 to September 2005. Read More

Rearing of Plateau pika (Ochotona daurica) captured in Mongolia.

Exp Anim 1998 Jul;47(3):203-6

Division of Laboratory Animal Resources, National Center of Neurology and Psychiatry, Tokyo, Japan.

We attempted to rear and breed Plateau pikas (Ochotona daurica) captured in Mongolia in 1994 and 1995. In rearing indoors, though coitus was observed, none of the females became pregnant. In rearing outdoors, males began to make high-pitched, continuous cries and the first offspring (3 newborns) were obtained in June, 1997. Read More

Parassitologia 1982 Dec;24(2-3):155-65

Two human cases of subcutaneous dirofilariasis are described in a 41 year-old woman and in a 14 year-old boy living in Venice Lido. In the first case, the development of a nodule at the left forearm had been preceded by generalized symptoms such as pruriginous urticarioid patches in various regions of the body, transitory swellings and 8% eosinophilia. From the nodule, an adult female of Dirofilaria repens was recovered with embryos visible in the uterus. Read More

Anatomy and function of the reproductive tract in the captive male tree shrew (Tupaia belangeri).

Biol Reprod 1982 Feb;26(1):169-82

The reproductive anatomy of the male tree shrew (Tupaia belangeri) was examined and compared with other Tupaiidae. The testes are located prepenially in a pigmented scrotum which is fused to the base of a pendulous penis. The terminal portion of the vas deferens is differentiated into an ampullary gland and joins the duct of the seminal vesicle to form a short ejaculatory duct. Read More
