PHARMACOKINETICS OF CEFTAZIDIME IN SIGNAL CRAYFISH () FOLLOWING A SINGLE DOSE.

Crustaceans are housed in zoos and aquariums and have also gained importance in the private sector and food industry. Shell lesions are common and often attributed to bacterial infections. However, few controlled studies have been performed evaluating antibiotics in crustaceans.

MILBEMYCIN OXIME (INTERCEPTOR) TREATMENT OF PYCNOGONID SEA SPIDER INFESTATION IN THREE SPECIES OF CORALS.

A coral reef system at the Steinhart Aquarium in San Francisco, CA, USA experienced a population explosion of pycnogonid sea spiders (Arthropoda: Class Pycnogonida) with subsequent deleterious health effects on the corals in the system. Sixteen coral colonies across three species (, , and ) were chosen from this system for milbemycin oxime immersion therapy trials, with the goal of decreasing or eradicating the sea spider population with minimal detrimental effect to the corals. Corals underwent two milbemycin immersion treatments, administered 1 wk apart, at the previously published aquatic invertebrate dose of 0.

A retrospective analysis of mortality in captive Magellanic penguins (Spheniscus magellanicus) in the United States, 2008-2018.

Mortality data for Magellanic penguins (Spheniscus magellanicus) housed in zoos and aquariums in the United States has not previously been published. Necropsy and histopathology records were examined for Magellanic penguins housed at 12 Association of Zoos and Aquariums institutions from 2008 through 2018. If birds lived through the first year, the mean longevity was found to be 18.

Leukemic histiocytic sarcoma in a captive common squirrel monkey (Saimiri sciureus) with Saimiriine Gammaherpesvirus 2 (Rhadinovirus), Saimiri sciureus lymphocryptovirus 2 (Lymphocryptovirus) and Squirrel monkey retrovirus (β-Retrovirus) coinfection.

Hematopoietic neoplasia other than lymphoma and leukemia is uncommon among non-human primates. Herein, we provide the first evidence of occurrence of leukemic histiocytic sarcoma in a captive common squirrel monkey with Saimiriine Gammaherpesvirus 2 (Rhadinovirus), Saimiri sciureus lymphocryptovirus 2 (Lymphocryptovirus), and Squirrel monkey retrovirus (β-Retrovirus) coinfection.

Managing Aged Animals in Zoos to Promote Positive Welfare: A Review and Future Directions.

Improvements in veterinary care, nutrition, and husbandry of animals living in zoos have led to an increase in the longevity of these animals over the past 30 years. In this same time period, the focus of animal welfare science has shifted from concerns over mitigating negative welfare impacts to promoting positive welfare experiences for animals. For instance, providing opportunities for animals to exert agency, solve problems, or acquire rewards are all associated with positive welfare outcomes.

SARCOCYSTIS NEURONA-ASSOCIATED MENINGOENCEPHALITIS IN A PACIFIC WALRUS ( ODOBENDUS ROSMARUS DIVERGENS).

A 21-yr-old intact male walrus ( Odobendus rosmarus divergens) presented with acute onset of shifting lameness, initially associated with breeding behaviors. Further clinical signs manifested, including muscle tremors, anorexia, hematuria, and coughing. Diagnostics were limited, as the animal would not offer behaviors for voluntary sample collection.

Plasma proteins and selected acute-phase proteins in the whitespotted bamboo shark (Chiloscyllium plagiosum).

Plasma protein electrophoresis has been shown to be an important tool when recognizing disease in various species. Plasma was harvested from twenty captive whitespotted bamboo sharks (Chiloscyllium plagiosum) and gel electrophoresis was used to characterize the following protein fractions: total protein, prealbumin, albumin, α-1 globulin, α-2 globulin, β globulin, γ globulin, C-reactive protein, serum amyloid A, and haptoglobin. The selected acute-phase proteins were assayed and reference intervals created for a population of captive whitespotted bamboo sharks, and then used to assess relationships between these protein concentration values, sex, and health status.

Ultrasonographic assessment of abdominal lymph nodes in puppies.

The jejunal and medial iliac lymph nodes of 53 clinically normal dogs between the age of 4 and 6 weeks were examined ultrasonographically. At least two jejunal and both left and right medial iliac lymph nodes were seen in all dogs. One hundred forty-five jejunal, 53 right medial iliac and 53 left medial iliac lymph nodes in six litters of dogs, for a total of 251 lymph nodes, were measured for cross sectional maximum diameters.
