Tonsillar squamous cell carcinoma in a male Lhasa Apso.

Squamous cell carcinoma (SCC) and more specifically tonsillar SCC are generally regarded as locally invasive with various rates of metastasis. A 13-year-old male Lhasa Apso was referred to the clinic with an unusual mass on his left tonsil and abnormal lumps under the tongue. The dog's food and water intake, breathing and heart rates, body temperature, capillary refill time, and blood tests were normal.

A review of Hepatozoonosis caused by in dogs.

is a type of single-celled organism is spread by ticks and commonly affects dogs. It is responsible for causing one of the most significant parasitic diseases in dogs, called Hepatozoonosis. It is considered one of the most common causes of canine vector-borne diseases because it is closely linked to (the brown dog tick), a species found worldwide.

Frequency and genotyping of in dogs of Urmia, northwest of Iran.

is a zoonotic protozoan infecting various vertebrates such as humans and domestic animals. The aim of this study was to determine the frequency and genotypes of using polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) in dogs of Urmia, Iran. Overall, 246 stool specimens were collected from 100 pet, 49 stray, and 97 shelter dogs in the Urmia, Iran.

Antioxidant effects of supplementation of 3,4-dihydroxyphenyl glycol on sperm parameters and oxidative markers following cryopreservation in canine semen.

Supplementing the extender with antioxidants with low molecular weight can enhance the quality of the post-thaw sperm during the freezing process. This study was aimed at determining the impacts of 3,4-dihydroxyphenyl glycol (DHPG) on the spermatozoa of the canine undergoing freeze-thawing process. In this study, 24 ejaculates were obtained from three mixed-breed dogs and were diluted in a Tris-based extender.

The evaluation of lycopene and cysteamine supplementation effects on sperm and oxidative stress parameters during chilled storage of canine semen.

The aim of this study was to evaluate the effects of different concentrations of lycopene and cysteamine on characteristics of sperm, liquid peroxidation and enzymatic activities in seminal plasma of canine semen preserved at 5°C for 72 hr. The semen samples were divided into eight aliquots: control, control sham (dimethyl sulfoxide 5%), lycopene groups (250, 500 and 750 µg/ml) and cysteamine groups (2.5, 5 and 10 mM).

Transmission of by (Acari: Ixodidae) in Dogs.

Background: is the most widely distributed tick in the world, which is partly due to its biological flexibility and the global distribution of its major host, the domestic dog. In Mediterranean region it could be principal reservoir host for usually transmitted by the phlebotomine sand flies. In this study, we evaluated the vector potential of in transmitting to uninfected dogs.
