abstract

Toxoplasmosis is one of the most common zoonoses worldwide. It was initially described in rodents and rabbits. There are few data on the morbidity and mortality of this disease among Brazilian marsupial fauna, such as opossums. These animals are of great importance regarding the epidemiology of this disease, given that they are prey for felids and other carnivores. With the aim of ascertaining the serological response to Toxoplasma gondii among marsupials (Didelphis spp.), 38 animals that had been caught in 14 districts of the urban area of the municipality of Bauru, state of São Paulo, were evaluated. The modified agglutination test (MAT) showed that 26.3% (10/38) of the samples analyzed were seropositive. It can be suggested that the opossums’ behavior and persistent proximity to human housing results in contact with cats and T. gondii infection, based on the frequency found in this study. This was the first study on the seroprevalence of T. gondii in opossums caught in the urban area of the municipality of Bauru, SP, and it highlights the need for environmental and health authorities of the municipality to monitor this zoonosis.

The aim of this study was to determine the effects of severe extreme thermal stress on the respiratory rate (panting) of unsheared and sheared rams in standing and lying position, and to analyse two temperature-humidity indices (THIs). Six mature Australian Merino rams from Northern Patagonia, three unshorn and three shorn, were subjected to 40 hours (8 hours each day for five days) of gradual increase in temperature from 25°C to 40°C, guaranteeing 4h daily at 40°C in a heat chamber. Respiratory rate (RR) was registered continuously by counting flank movements, and the ambient air temperature and relative humidity were recorded every five minutes inside the heat chamber. From 1413 RR measurements, descriptive and modelling analyses were performed. Panting as a response variable was distributed into five categories, and fixed effects such as THI, wool (unshorn/shorn), and position (standing/lying) were considered. No significant differences were observed between the panting score in the unshorn (standing or lying) and standing (unshorn or shorn) sheep, but significant differences were observed in shorn and lying rams. The explanations could be that heat production from muscle activity was lower and the transfer and heat lost by conduction to the floor was easier in the rams with shorter fleece (at least 0.7 inches long). However, in the unshorn rams, their wool acted as an insulator, both with air as well as the floor. Australian Merino rams from Northern Patagonia are heat tolerant to an environment between 31.5°C and 42°C, and 32% to 48% humidity for 40 hours over five days. The rams were in the first phase of panting, and the normal rectal temperatures registered daily when leaving the heat chamber confirmed that regulation of body temperature was possible. The LPHSI’s THI was adjusted to improve the analysis of the RR more than the National Research Council’s THI.

Estrus synchronization is a reproductive biotechnology used to improve artificial insemination or pairing through the manipulation of the estrous cycle at a desirable time. Employing this technique in captive pacas (Cuniculus paca L.) is important because it creates expectation of meeting the demand for paca meat and, consequently, reduces poaching. Thus, this research aims to verify the effect of a progestogen implant associated with two doses of eCG on the synchronization and induction of fertile estrus. Twenty-seven adult pacas were used, 18 non-pregnant females and nine males, divided into three groups. G1 and G2 females groups (treatments) received 1.5 mg Norgestomet and were injected intramuscularly, seven days later, with 0.13 mg of prostaglandin. After 24 hours the implants were removed and the animals immediately received 25 IU and 50 IU of ECG intramuscularly, respectively. The mating of the three groups took place on the same days. G3 females’ group (control) showed estrus on different days after D0. Females under treatment displayed estrus only after removing the implant (D8). G1, G2, and G3 pregnancy rates were 100%, 66%, and 50%, respectively. Regarding births per parturition, 100% of G1 and G3 produced one offspring, while 50% of G2 produced two. Progestogen in the form of subcutaneous implants was effective in mimicking the luteal phase of the estrous cycle. After removal, implants favored the occurrence of a fertile estrus. As a conclusion, further studies must be conducted in order to establish in-depth possible association between 50 IU of eCG, and the occurrence of twin pregnancies.

During fertilization, spermatozoa interact with the zona pellucida (ZP) through the binding between the acrosome and proteins 2 and 3 (ZP2 and ZP3). The perivitelline membrane of chicken egg yolk is homologous to the mammalian ZP3, which allows the binding of sperm of several species. The aim of this study was to standardize and evaluate the efficiency of sperm-binding to the perivitelline membrane of chicken eggs as a functional method for canine semen evaluation. For this purpose, nine post-thaw sperm samples were used, which were divided into two aliquots: the first was kept in water bath at 37ºC (live sample) and the second was submitted to cold shock to induce cellular damage (dead sample). The two aliquots were mixed on five proportions, corresponding to 0%, 25%, 50%, 75%, and 100% of viable cells, and the binding test was performed by analyzing the number of spermatozoa bonded to the perivitelline membrane by means of computerized assessment of sperm motility (CASA) or conventional microscopy. Additionally, samples were submitted to sperm motility analysis, evaluation of plasmatic and acrosomal membrane integrity, and sperm mitochondrial activity. The sperm-binding test to the perivitelline membrane of chicken egg yolk was considered a feasible sperm analysis test for both fertilizing capacity and overall sperm attributes evaluation, mainly when the analysis is performed by a conventional microscope, which expands its practicality to the majority of canine reproduction laboratories.

The goal of this study was to describe the anatomy of the femoral artery in wild canids such as the crab-eating fox (Cerdocyon thous), the hoary fox (Lycalopex vetulus), and the maned wolf (Chrysocyon brachyurus). Two specimens from each canid group were used. Red dyed latex was injected in the arterial system of the animals, which were then fixed in 10% formaldehyde aqueous solution and dissected following the routine techniques in macroscopic anatomy. In the three canid groups, the arterial pattern was similar to that described for domestic canids, in which the deep femoral artery rises from the external iliac artery, still in the abdominal cavity, and sends its first branch, the lateral circumflex femoral artery. A few muscular branches, one or two caudal femoral arteries, and the terminal branches – the descending genicular artery, the saphenous artery, and the popliteal artery – are all originated from the femoral artery. The origin pattern of these vessels also shows similarities with those from domestic canids, sometimes forming trunks and occasionally rising individually. Thus, it can be concluded that the anatomical pattern of the femoral artery and its branches in wild canids shows similarities with that from domestic canids, but inherent variations in each species are also present.

As intussuscepções são acidentes intestinais incomuns e que podem resultar em desconforto abdominal agudo e progressivo ou recorrente em potros. Esta condição afeta potros neonatos de forma assintomática e de 3 a 12 meses são emergências cirúrgicas quando envolvem o intestino delgado, principalmente o jejuno. A avaliação ultrassonográfica transabdominal é um importante para o exame desses animais devido às limitações de seu tamanho para avaliações do abdômen agudo. O presente relato de caso mostra a importância da utilização do ultrassom transabdominal em potros com abdômen agudo

Sonography is a safe and non-invasive imaging modality, with the added benefit of providing dynamic images. Power Doppler sonography allows blood vessel identification regardless of flow intensity or direction. A one-year-old Ile de France ewe was admitted to the FMVZ-USP Veterinary Hospital with a complete tibial fracture. The animal was submitted to general inhalation anesthesia and fracture repair using a 3.5 mm locking compression plate. Power Doppler sonography was used to assess neovascularization over the course of the bone healing process. Formation of new vessels was noted between postoperative days 14 and 21; new vessels regressed progressively on subsequent assessments (postoperative days 28 and 35). Power Doppler sonography enabled early detection of newly formed blood vessels at the fracture site. The non-invasive nature of this imaging modality prevented patient stress and provided useful information on the progression of bone healing. Early neovascularization was thought to reflect successful postoperative healing of the tibial fracture described.
