Sparganosis due to sp. (cestoda; Diphyllobothriidae) in captive meerkats ().

We report three cases of sparganosis due to plerocercoids of the tapeworm sp. in captive meerkats () from a zoo exhibit in the southeastern United States. Two meerkats were euthanized, one due to an uncontrollable seizure and the other due to trauma, and at necropsy cysts containing cestode larvae were observed.

Motility based assays using cultured fourth stage larvae fail to provide consistent discrimination between known avermectin-resistant and -susceptible isolates of Cooperia spp.

The fecal egg count reduction test (FECRT) is the only method commonly used for diagnosing anthelmintic resistance in gastrointestinal nematodes of cattle, but this method has several drawbacks that have limited its widescale implementation. Consequently, there exists a need to develop better methods for diagnosing resistance. Assays based on larval motility are used commonly for screening potential drug candidates, and for detecting drug resistance, but previous work in our lab demonstrated that the L3 stage failed to discriminate between avermectin-resistant and susceptible isolates of Cooperia spp.

Parasite survey on a captive wolf population using classical techniques and ELISA coproantigen detection, USA.

As laws change around the United States, wildlife that were once kept as companion animals are now often confiscated by local authorities. They are then euthanized unless a home is found for them at a sanctuary. Wolf sanctuaries are, therefore, becoming increasingly important for their conservation and management.

Ectopic infection by Dioctophyme renale in a dog from Georgia, USA, and a review of cases of ectopic dioctophymosis in companion animals in the Americas.

We report a case of ectopic dioctophymosis in an outdoor, eight-year-old spayed female, Coonhound-mix dog from Murrayville, Hall County, Georgia, USA. The dog presented to the clinic with an apparent puncture wound on her right, most caudal mammary gland, draining a serosanguinous discharge along with significant edema and thickening of the surrounding tissues. After initial physical examination the dog was placed into a cage awaiting diagnostic procedures.

Comparison of fecal egg counting methods in four livestock species.

Gastrointestinal nematode parasites are important pathogens of all domesticated livestock species. Fecal egg counts (FEC) are routinely used for evaluating anthelmintic efficacy and for making targeted anthelmintic treatment decisions. Numerous FEC techniques exist and vary in precision and accuracy.

Utilization of composite fecal samples for detection of anthelmintic resistance in gastrointestinal nematodes of cattle.

Recent reports indicate that anthelmintic resistance in gastrointestinal nematodes of cattle is becoming increasingly prevalent worldwide. Presently, the fecal egg count reduction test (FECRT) is the only means available for detection of resistance to anthelmintics in cattle herds at the farm level. However, the FECRT is labor and cost intensive, and consequently is only rarely performed on cattle farms unless for research purposes.

Prevalence of antibodies to spotted fever group Rickettsia spp. and Ehrlichia spp. in coyotes (Canis latrans) in Oklahoma and Texas, USA.

Coyotes (Canis latrans) are commonly infested with ticks, including Amblyomma americanum, the predominant vector of Ehrlichia chaffeensis and Ehrlichia ewingii; Dermacentor variabilis, an important vector of Rickettsia rickettsii; and Amblyomma maculatum, a major vector of Rickettsia parkeri, a spotted fever group (SFG) Rickettsia. To determine the degree to which coyotes are infected with or exposed to tick-borne bacterial disease agents, serum samples collected from coyotes in Oklahoma and Texas were tested for antibodies reactive to R. rickettsii, Ehrlichia canis, E.

Detection of Dirofilaria immitis and Ehrlichia species in coyotes (Canis latrans), from rural Oklahoma and Texas.

There is a lack of knowledge regarding the prevalence of Dirofilaria immitis and Ehrlichia spp. in coyotes in Oklahoma and Texas. Documenting the prevalence of these vector-borne disease agents in coyotes from Oklahoma and Texas underscores the importance of wild canids as reservoir hosts that infect companion animals and humans.

Detection of Trichinella murrelli in coyotes (Canis latrans) from Oklahoma and North Texas.

We determined the prevalence and mean intensity of Trichinella sp. infection in coyotes from six counties in Oklahoma and one in northern Texas. Tongues from 77 coyotes were examined using histology and artificial tissue digestion.
