Bilateral Abscesses Of The Maxillary Carnassial Teeth In A Female Pekinese, Abutorab Tabatabaei Naeini, Alireza Raayat Jahromi, Samira Mehrshad

Turkish Journal of Veterinary & Animal Sciences

Tooth infections are typically seen in older dogs as a result of poor oral hygiene (periodontal disease) or traumatic tooth fractures (endodontic and periapical disease). An 8-year-old female Pekinese was presented due to bilateral draining tracts located just under its eyes, and a history of healing and recurrence of the lesions after about 3 weeks of systemic antibiotic therapy. Dental radiography revealed bilateral carnassial tooth root abscesses. Both teeth were extracted under general anesthesia. With proper postoperative care the abscesses healed with no further complications.

First Report Of Canine Visceral Leishmaniasis In Bulgaria, Ilia Tsachev, Ioannis D. Kyriazis, Sofia Boutsini, Evdokia Karagouni, Eleni Dotsika

Turkish Journal of Veterinary & Animal Sciences

Seroepidemiological studies on canine leishmaniasis in Bulgaria, even in areas where human leishmaniasis has been detected, are controversial. This report describes 2 clinical cases of canine visceral leishmaniasis. The disease was confirmed by microscopical, serological, and molecular methods. It is, therefore, suggested that infected dogs could constitute the reservoir for human leishmaniasis in the country.

Intestinal Geotrichosis In A German Shepherd, Yajane Lee, Wei-Li Hsu, Chin-Fu Lin, Shao-Wei Lee, Feng-Pang Cheng

Turkish Journal of Veterinary & Animal Sciences

A 4-year-old sexually intact male German shepherd with a 3-month history of chronic watery diarrhea was referred to the Veterinary Medical Teaching Hospital. Dehydration and serum biochemistry revealed hypoalbuminemia, and fecal material contained a large quantity of round arthroconidia that were microscopically observed. A specimen was submitted for fungal culture and yielded a white to cream-colored subsurface colony. Microorganisms derived from the colony exhibited chains of smooth, septate hyaline hyphae that were producing 1-celled arthroconidia. Geotrichum candidum was thus identified. Colonoscopic features included erythema, edema, and loss of the usual fine vascular pattern, with granularity of the mucosa of the ...

The Impact Of Conservation On The Status Of The World's Vertebrates, M Hoffmann, C Hilton-Taylor, A Angulo, M Bohm, Tm Brooks, Et Al.

VIMS Articles

Using data for 25,780 species categorized on the International Union for Conservation of Nature Red List, we present an assessment of the status of the world's vertebrates. One-fifth of species are classified as Threatened, and we show that this figure is increasing: On average, 52 species of mammals, birds, and amphibians move one category closer to extinction each year. However, this overall pattern conceals the impact of conservation successes, and we show that the rate of deterioration would have been at least one-fifth again as much in the absence of these. Nonetheless, current conservation efforts remain insufficient to ...

High Particle Export Over The Continental Shelf Of The West Antarctic Peninsula, Ko Buesseler, Amp Mcdonnell, Ome Schofield, Dk Steinberg, Hw Ducklow

VIMS Articles

Drifting cylindrical traps and the flux proxy Th-234 indicate more than an order of magnitude higher sinking fluxes of particulate carbon and Th-234 in January 2009 than measured by a time-series conical trap used regularly on the shelf of the west Antarctic Peninsula (WAP). The higher fluxes measured in this study have several implications for our understanding of the WAP ecosystem. Larger sinking fluxes result in a revised export efficiency of at least 10% (C flux/net primary production) and a requisite lower regeneration efficiency in surface waters. High fluxes also result in a large supply of sinking organic matter ...

Changes In Age Composition And Growth Characteristics Of Atlantic Sturgeon (Acipenser Oxyrinchus Oxyrinchus) Over 400 Years, Mt Balazik, Gc Garman, Ml Fine, Ch Hager, Sp Mcininch

VIMS Articles

Populations of sturgeon (Acipenseridae) have experienced global declines, and in some cases extirpation, during the past century. In the current era of climate change and over-harvesting of fishery resources, climate models, based on uncertain boundary conditions, are being used to predict future effects on the Earth's biota. A collection of approximately 400-year-old Atlantic sturgeon spines from a midden in colonial Jamestown, VA, USA, allowed us to compare the age structure and growth rate for a pre-industrial population during a 'mini-ice age' with samples collected from the modern population in the same reach of the James River. Compared with modern ...

Challenges Of Modeling Depth-Integrated Marine Primary Productivity Over Multiple Decades: A Case Study At Bats And Hot, Vs Saba, Mam Friedrichs, Me Carr, D Antoine, Ra Armstrong, Et Al.

VIMS Articles

The performance of 36 models (22 ocean color models and 14 biogeochemical ocean circulation models (BOGCMs)) that estimate depth-integrated marine net primary productivity (NPP) was assessed by comparing their output to in situ C-14 data at the Bermuda Atlantic Time series Study (BATS) and the Hawaii Ocean Time series (HOT) over nearly two decades. Specifically, skill was assessed based on the models' ability to estimate the observed mean, variability, and trends of NPP. At both sites, more than 90% of the models underestimated mean NPP, with the average bias of the BOGCMs being nearly twice that of the ocean color ...

VIMS Articles

Striped bass (Morone saxatilis) in the Chesapeake Bay are currently experiencing a very high prevalence of mycobacteriosis associated with newly described Mycobacterium species, Mycobacterium pseudoshottsii and M. shottsii. The ecology of these mycobacteria outside the striped bass host is currently unknown. In this work, we developed quantitative real-time PCR assays for M. pseudoshottsii and M. shottsii and applied these assays to DNA extracts from Chesapeake Bay water and sediment samples, as well as to tissues from two dominant prey of striped bass, Atlantic menhaden (Brevoortia tyrannus) and bay anchovy (Anchoa mitchilli). Mycobacterium pseudoshottsii was found to be ubiquitous in water ...

Atlantic herring (Clupea harengus) are crucial members of the ecosystem and economy of the Northwest Atlantic, and a challenging species for management, which in the United States is a multistakeholder process, involving commercial and recreational fishing interests, conservation organizations, state and federal governments, and other interested parties. Given the large number of stakeholders, fisheries management has been conceptualized as a governance network, through which multiple parties ...


Dead In The Water: The Fate Of Copepod Carcasses In The York River Estuary, Virginia, DT Elliott, CK Harris, KW Tang 2010 Virginia Institute of Marine Science

Dead In The Water: The Fate Of Copepod Carcasses In The York River Estuary, Virginia, Dt Elliott, Ck Harris, Kw Tang

VIMS Articles

Using laboratory and field experiments we investigated three fates of copepod carcass organic matter in the York River estuary, Virginia: ingestion by planktivores (necrophagy), microbial decomposition, and removal by gravitational settling in the presence of turbulence (sinking). The ctenophore Mnemiopsis leidyi ingested live copepods and carcasses indiscriminately in feeding experiments. Microbial decomposition led to ca. 50% of carcass dry weight loss within 8 h after death. Carcass settling velocities in still water were ca. 0.1 cm s(-1), implying short residence time (hours) in the shallow estuary. However, turbulent mixing kept carcasses in suspension much of the time, reducing ...
