Survey of SARS-CoV-2 in dogs and cats in high-risk areas during the second wave of COVID-19 outbreak, Thailand.

A cross-sectional survey of SARS-CoV-2 in domestic dogs and cats was conducted in high-risk areas, five subdistricts of Samut Sakhon Province, the epicenter of the second wave of the COVID-19 outbreak in Thailand in February 2021. A total of 523 swab samples (nasal, oral, and rectal swabs) and 159 serum samples from dogs (n = 83) and cats (n = 93) were collected and tested for SARS-CoV-2 RNA and antibodies. All swab samples tested negative for SARS-CoV-2 RNA by real-time RT-PCR with three panels of specific primers and probes.

Relationship between the number of Hepatozoon canis gamonts and hematobiochemical values in dogs.

The occurrence of canine hepatozoonosis in Thailand is primarily caused by Hepatozoon canis. Recently, the relationship of hematology and biochemistry with this disease has been studied, but knowledge regarding the relationship between the quantity of H. canis intracellular gamonts and the hematological profile has not yet been reported.
