Sex Determination in Two Species of Anuran Amphibians by Magnetic Resonance Imaging and Ultrasound Techniques.

The objective of the present study was to evaluate whether gender determination in two amphibian species ( and ) can be reliably carried out by means of magnetic resonance imaging (benchtop magnetic resonance imaging; BT-MRI) or ultrasound (high-resolution ultrasound; HR-US) techniques. Two species of healthy, sexually mature anurans have been used in the present study. Eight (blind study) and six were used as controls.

Comparative physiology of glomerular filtration rate by plasma clearance of exogenous creatinine and exo-iohexol in six different avian species.

Early diagnosis of kidney diseases in avian species is limited. Endogenous markers currently used in avian practice are not sensitive enough to identify early kidney failure. Consequently, alternative markers should be evaluated.

Clinicopathologic findings of naturally occurring Rabbit Hemorrhagic Disease Virus 2 infection in pet rabbits.

Two pet rabbits were presented with an acute decrease in appetite and activity. Rabbit 1 showed severe hypothermia, bradycardia, arrhythmias, a heart murmur, dyspnea, occlusion of the nares with secretions, icterus, dehydration, and gaseous gastrointestinal dilation. The urine was dark yellow.

Pharmacokinetics of meloxicam during multiple oral or intramuscular dose administration to African grey parrots (Psittacus erithacus).

OBJECTIVE To determine the pharmacokinetics of meloxicam in African grey parrots (Psittacus erithacus) during administration of multiple doses. ANIMALS 6 healthy African grey parrots. PROCEDURES Meloxicam was administered at each of 3 dosages (1 mg/kg, IM, q 24 h, for 7 days; 1 mg/kg, PO, q 24 h, for 12 days; and 1.

Seminal Vesiculitis in Three Pet Rabbits ( Oryctolagus cuniculus ).

To date, descriptions of pathologic conditions of the seminal vesicle in rabbits are scarce and limited to the laboratory animals in experimental conditions. The present article describes three cases of strangury, abdominal pain, and anorexia associated with seminal vesiculitis in pet rabbits. Three non-neutered male pet rabbits aged 3.

KLOSSIELLA DULCIS N. SP. (APICOMPLEXA: KLOSSIELLIDAE) IN THE KIDNEYS OF PETAURUS BREVICEPS (MARSUPIALIA: PETAURIDAE).

Two cases of renal klossiellosis were diagnosed by histopathology in pet sugar gliders (Petaurus breviceps). In both cases, parasites were associated with tubular dilation and mild interstitial nephritis. Rare schizonts were seen in the proximal convoluted renal tubular epithelium, whereas all other life cycle stages were found within distal convoluted tubule cells or the urinary space of the structures distal to the loop of Henle.

Plasmatic L-lactate in pet rabbits: association with morbidity and mortality at 14 days.

Background: The clinical relevance of plasmatic L-lactate concentration (PLLC) is unknown in rabbits. Due to an entirely different metabolism of lactic acid, PLLC in rabbits can reach much higher concentrations than in other species.

Objectives: The aim of this study was to establish a reference interval (95% RI) for venous PLLC in pet rabbits and to assess its diagnostic and prognostic significance in ill pet rabbits.

Effects of Meloxicam on Hematologic and Plasma Biochemical Analyte Values and Results of Histologic Examination of Kidney Biopsy Specimens of African Grey Parrots (Psittacus erithacus).

In this study we evaluated the effects of meloxicam administered at 0.5 mg/kg IM q12h for 14 days on hematologic and plasma biochemical values and on kidney tissue in 11 healthy African grey parrots (Psittacus erithacus). Before treatment with meloxicam, blood samples were collected and renal biopsy samples were obtained from the cranial portion of the left kidney from each of the birds.

Point-of-care blood gas and electrolyte analysis in rabbits.

This article outlines a practical approach for the use of blood-gas analysis in pet rabbits using the I-STAT analyzer. Sampling techniques and a theoretic approach to diagnosis are described. The following 95% RI were obtained from venous samples of 45 healthy rabbits: pH (7.

Acid-base status in the avian patient using a portable point-of-care analyzer.

The i-STAT PCA can be used as a blood analyzer in critical avian patients, although single values must be interpreted carefully. The study of the acid-base status in companion birds is still in its infancy. Further research is needed to establish normal reference values in arterial blood gases, compare them with venous blood gas, and to determine if the formulas that deviate from small animal medicine are or are not applicable.
