Rabbits as Animal Models for Anti-Tick Vaccine Development
Studies evaluating candidate tick-derived proteins as anti-tick vaccines in natural hosts have been limited due to high costs. To overcome this problem, animal models are used in immunization tests. The most commonly used rabbit breeds were New Zealand (73.8%), Japanese white (19%), Californians (4.8%) and Flemish lop-eared (2.4%) rabbits. Anti-tick vaccines efficacy resulted in up to 99.9%. Haemaphysalis longicornis (17.9%) and Ornithodoros moubata (12.8%) were the most common tick models in vaccination trials. Experiments with rabbits have revealed that some proteins (CoAQP, OeAQP, OeAQP1, Bm86, GST-Hl, 64TRP, serpins and voraxin) can induce immune responses against various tick species.

Vectors and Hosts of Rickettsia felis in Europe
Rickettsia felis in an obligate intracellular Gram negative bacterium and the causative agent of flea-borne spotted fever (FBSF). Rickettsia felis requires a vertebrate and invertebrate host to survive and reproduce. The cat flea (Ctenocephalides felis) is considered as the primary vector and the reservoir host of this pathogen.

Porcine Epidemic Diarrhea Virus
Porcine epidemic diarrhea virus (PEDV) is a porcine enteric coronavirus, which is one of the main causative agents of porcine epidemic diarrhea (PED), with 100% morbidity and 80–100% mortality in neonatal piglets. Since 2010, large-scale PED caused by highly pathogenic variants of PEDV has occurred successively in China and other countries in the world, posing a great threat to the global pig industry.

Influenza A Virus Subtypes in Chile
The influenza A virus (IAV) poses a significant global threat to public health and food security. Chile’s encounter with IAV began in 2002, with the highly pathogenic avian influenza (HPAI) H7N3 virus, derived from a unique South American low pathogenic avian influenza (LPAI) virus.

Immune Responses Potentially Involved in Brucella-Induced Pregnancy Complications
Infection by Brucella species in pregnant animals and humans is associated with an increased risk of abortion, preterm birth, and transmission of the infection to the offspring. The pathogen has a marked tropism for the placenta and the pregnant uterus and has the ability to invade and replicate within cells of the maternal–fetal unit, including trophoblasts and decidual cells. Placentitis is a common finding in infected pregnant animals. Several proinflammatory factors have been found to be increased in both the placenta of Brucella-infected animals and in trophoblasts or decidual cells infected in vitro. As normal pregnancies require an anti-inflammatory placental environment during most of the gestational period, Brucella-induced placentitis is thought to be associated with the obstetric complications of brucellosis.

Endocrine Diseases in Donkeys
Hyperlipemia, defined as abnormally high blood triglyceride concentrations, is the most common metabolic disease in donkeys. In contrast, metabolic syndrome, insulin dysregulation (ID) and pituitary pars intermedia dysfunction (PPID) are the most common endocrine disorders in this species. Although diagnostic approaches for these conditions are similar to horses, donkey-specific protocols must be used.

Coxiella burnetii Infection in Cats
Coxiella burnetii is the etiologic agent of the zoonosis called Q fever. The disease was first described in Australia in 1935 by Edward Holbrook Derrick who investigated a disease in a group of abattoir workers in Brisbane, Queensland, Australia. The “Q” comes from “query” fever, as named by Derrick.

Dog DEA 1 prevalance in Luanda (Angola)
Prevalence of dog blood groups varies geographically and between breeds. In dogs, the risk of an acute hemolytic transfusion reaction at the first transfusion is negligible; however, mismatched transfusions may produce alloimmunization. To avoid fatal acute hemolytic reactions in subsequent blood transfusions, it´s important to recognize blood groups and to blood type both the donor and the recipient. this work describes for the first time the DEA 1 prevalence in a canine population in Luanda (Angola) and evaluates the alloimmunization risk after an incompatible blood transfusion.

Hematological Reference Intervals in Miranda's Donkey
The Miranda’s donkey is a Portuguese breed from northern Portugal considered endangered. Several researches in different scientific areas have been conducted to help in these animals preservation. The knowledge of hematological reference intervals is important to characterize the breed, identify the health status of the animals and help veterinarians in the diagnosis of diseases and follow-up of patients. This study aimed to determine the hematological reference intervals for healthy Miranda’s donkeys and to evaluate the interference of sex and age in these parameters. Only age interfered in the hematological values and should be considered when interpreting the results. The results described here can be used to assess the health of animals and herds, guide the diagnosis of diseases and assist in the selection of healthy animals for reproduction, contributing to the preservation of the breed.
