The clinical presentation of cat and dog allergy vary from discomfort caused by rhinoconjuncitivitis to severe asthma. Exposure to allergens from these animals is ubiquitous and allergic sensitization to cat or dog affect up to 25% of all children and adults, but allergic sensitization does not always cause symptoms. The introduction of molecular-based allergy diagnostics has improved the possibility to characterize the allergic patient in greater detail. However, the full clinical potential of using molecular allergology in the diagnosis, characterization and treatment of patients with allergy to cats and dogs has not yet been established, although significant progress has been made during the last decade, which will be reviewed in detail in this paper.

Companion animals are major reservoirs of zoonotic parasites and pathogens. Among these, ticks and tick-borne pathogens are of particular concern. Efforts to study the zoonotic risks associated with companion animals in Singapore have been hampered by a poor understanding of the ticks of local dogs and cats.

: While antibiotic usage in farm animals has been systematically monitored and reduced in many countries, including Germany, data on companion animals such as dogs and cats remain scarce. To address this gap, a study was conducted in Germany to analyze patterns of antibiotic use in dogs and cats. : Antibiotic usage data were obtained from debevet, a cloud-based veterinary practice management software based in Berlin, Germany.

The Erythrocyte Sedimentation Rate (ESR) in Veterinary Medicine: A Focused Review in Dogs and Cats.

The erythrocyte sedimentation rate (ESR) measures the rate at which erythrocytes aggregate and sediment in a fixed time in an anticoagulated blood tube and is expressed as a speed (mm/h). The ESR is still widely used in human medicine mainly as a modified or alternate method to the original Westergren. In veterinary medicine, it was employed in the 1940s-1960s after which it was gradually abandoned or rarely employed.

Detection of selected vector-borne pathogens in domestic animals, ectoparasites, and their owners in a rural community in Southwest Guatemala.

Vet Parasitol Reg Stud Reports

Vector-borne pathogens, which are transmitted by blood-feeding arthropods to animals and people, are common in tropical regions where, combined with economic factors, can cause significant public health burden. A community-level study was undertaken in southwestern Guatemala to assess the presence of vector-borne pathogens in blood samples from humans (n = 98), their animals (n = 90), and ectoparasites (n = 83) over a period of 2 weeks. Human capillary blood was collected from participant's index finger, and animal venous blood (chickens, pigs, dogs, and cats) was collected from the jugular or cephalic veins at the enrollment period of a concurrent study.

Dirofilariosis, a mosquito-borne disease caused by and , affects canids, felids and occasionally humans. Recent evidence suggests that prevalence is rising in the canine populations in several areas of Brazil, even those historically considered to be non-endemic, highlighting the need for ongoing surveillance. However, prevalence studies are frequently based on inference from single diagnostic methods, and it is acknowledged that this may lead to biases and an underestimation of the disease situation.
