ABSTRACT We aimed to identify behavioral changes or welfare impairments in cats in response to home isolation due to the COVID-19 pandemic in Brazil, as well as the emotional role these animals may play with their owners. Online questionnaires were answered by 419 cat’s owners in Brazil, who reported changes in the household routine because of to the COVID-19 pandemic. The questions addressed information about the cat in the household, the tutor-cat relationship, the feline behavior, the environment, and the changes occurred in the face of social isolation. It was evident that changes in people's routines were frequent and staying longer at home was the change most reported by the study participants. Thus, cats were left alone for less time compared to the period before the quarantine, which led to an increase in the amount of time that owners spent playing or paying attention to their cats. The quarantine period generated minimal undesirable behavioral changes in the cats, and the fact that the owners stayed home longer contributed to reducing these changes. The fact that a cat could become infected by SARS-CoV-2 was known by less than half of the interviewees, which did not influence any owner to think of getting rid of their cat. We highlight that feline companionship was considered by their owners as beneficial, as it helped them cope with the quarantine period, and allowed for increased affectionate bonds between the owners and their cats, also reflecting in a perception of greater happiness from their cats.

A large number of the parasitic agents that alter the health of swine could be spread to humans, especially in backyard conditions, and, many times, cause difficulties in public health and food availability. For that reason, this investigation was conducted to determine the seroprevalence and risk factors associated to swine cysticercosis and Trichinella spiralis in backyard pigs in Bucaramanga province, Colombia. A total of 380 serum samples were used for the search of T. spiralis and Tenia solium antibodies, by the ELISA. The seroprevalence of T. solium cysticercosis infection was 40.5%, whilst anti-T. spiralis antibodies were not observed in the processed samples. Regarding risk factors, free-ranging pigs and non-dewormed pigs showed almost 3 (OR=2.9; p≤0.05) and 2.7 (OR=2.7; p≤0.05) times more risk of presenting antibodies against T. solium cysticercosis. The seroprevalence of swine cysticercosis found in this investigation can be caused to bad buildings, and the absence of cleanliness in the buildings thus increasing the spread of parasites zoonotic potential among swine and people. For this reason, adequate sanitary management and health education measures must be applied to reduce the possible transmission of these parasites.

The aim of this study was to determine whether ultrasound imaging is an efficient method to assess subcutaneous fat in cats, the anatomical sites where more significant fat deposition occurs, and if there is a correlation between subcutaneous fat thickness and serum levels of cholesterol, triglycerides, and fructosamine. A total of 30 healthy adult cats were used and divided into three groups of 10 animals each, based on the estimated body condition score (BCS). The ideal group (IG) included cats with BCS 3; the overweight group (OWG), with BCS 4; and the obese group (OG), with BCS 5. Ultrasonographic measurement of subcutaneous fat was conducted in five anatomical regions: lumbar, abdominal, thoracic, femoral, and pectoral. We observed that obese cats had greater fat deposition in the abdominal and thoracic regions when compared to those with ideal weight, and that cholesterol and triglyceride levels were higher with the increase in subcutaneous fat thickness in the thoracic region. Nonetheless, there were no differences in fat deposition in the OWG compared to cats from the IG and OG. Ultrasonography allows to differentiate obese cats from those with ideal weight through the analysis of subcutaneous fat thickness in the abdominal and thoracic regions, rendering this method efficient and less subjective.

We report ectoparasites found on humans and wildlife from different locations in southeastern Brazil. Ectoparasites were stored in 70% alcohol and visually identified under a stereo microscope with the help of identification keys. Genomic DNA of ticks was extracted and used in the Polymerase Chain Reaction (PCR) to detect the presence of tick-borne pathogens. Sixteen species of ectoparasites (six ticks, one lice, four fleas, four flies, and one bedbug) were identified on ten host species, including humans, other mammals, and birds. We report the first record of the parasitism of Amblyomma longirostre on Didelphis aurita, Microlynchia pussila on Turdus leucomelas, Ornithoica vicina and Ornithocoris pallidus on Psittacara leucophthalmus and O. pallidus on Homo sapiens. In addition, we also report the first record of O. vicina in the state of Minas Gerais and the infection by Rickettsia sp. in Amblyomma varium.

This study aimed to determine whether hyperbaric oxygen therapy (HBOT) alters oxidative biomarkers after elective ovariohysterectomy (OHE). For this purpose, 45 healthy female cats were randomized into three groups: the hyperbaric group (HG): 15 animals pretreated with HBOT and submitted to OHE; the hyperbaric control group (HCG): 15 animals pretreated with HBOT without surgery; and the sham group (SHAM): 15 female cats submitted to OHE without pretreatment. The following biomarkers were evaluated: superoxide dismutase (SOD) and catalase (CAT), reactive oxygen species (ROS), thiobarbituric acid reactive substances (TBARS), acetylcholinesterase (AChE), and butyrylcholinesterase (BChE). The collection times were: T1 = before the surgery for the operated groups and after sedation in the HCG; T2 = 30 min after reversal of sedation (HCG) or at the time of extubation in the other groups; T3 = 24 hr after T2. There was no difference regarding serum dosage of ROS, AChE, or BChE. There was an increase in TBARS in the T3 SHAM compared to the T3 HG (p=0.043). Moreover, CAT activity decreased in T2 SHAM and T3 SHAM compared to T1 SHAM (p=0.012 and p<0.001mauric); T2 SHAM had lower CAT activity than T2 HCG (p=0.05). Additionally, the T3 SHAM was lower than the T3 HG (p=0.030) and T3 HCG (p=0.050). There was reduced SOD in the T2 SHAM compared to the T2 HG (p=0.033) and T2 HCG (p=0.027). Similarly, the T3 SHAM decreased compared to the T3 HG (p=0.039) and T3 HCG (p=0.019).

The objective of this study was to determine to what extent the oculocardiac reflex (OCR) progressively rises with increasing external pressures over the superior eyelid. Controlled external weights were applied to the left eyelid of ten conscious healthy adult beagle dogs, using an electronic von Frey aesthesiometer with a modified probe. Four different weights (200 g, 300 g, 400 g and 800 g) were applied on four different non-consecutive days (with one-week intervals). Pressure was applied by pushing the device against the superior eyelid. The baseline heart rate was primarily recorded using an electrocardiograph (ECG). Then, indices of heart rate variability such as R-R intervals and vasovagal tonus index (VVTI) were calculated from the ECG tracings using twenty consecutive QRS complexes from each dog, before and after a selected set of graded weights were applied to the eye. Median R-R interval significantly increased when an external weight of 200 g was applied and peaked at 300 g. VVTI values peaked at 400 g. With higher pressures, the proportional increase was smaller in both R-R intervals and VVTI. We concluded that external eye pressure using a weight of 200 g or more is sufficient to elicit an OCR response in conscious dogs. Pressures above 400 g started to activate compensatory mechanisms that counteracted with the OCR, probably linked to an adrenergic response induced by the animal’s discomfort. Changes in R-R intervals might be used as an early OCR marker, while VVTI apparently was less influenced by potential sympathetic responses.

Uncontrolled parasitic infections in livestock can increase the potential risk of transmission between human societies. Owing to the socioeconomic challenges of these diseases in slaughtered sheep, the current study aimed to forecast the prevalence of these infections in a central slaughterhouse in Alborz Province, north-central Iran. Data from 2009 to 2018 on parasitic infections in slaughtered sheep presented at a slaughterhouse were compiled and the prevalence of these diseases was computed. The prevalence has been considered as a time series and afterward, RStudio software using the best-fitted ARIMA model was applied to forecast the monthly variation in prevalence rates. From 2009 to 2018, a total of 1,339,196 sheep were slaughtered in the studied slaughterhouse. The Iranian Afshari breed was the most slaughtered sheep and, a total of 77.6% of these animals were raised under traditional farming system. In addition to the Alborz province, slaughtered sheep were brought from five other provinces, including Zanjan, Qazvin, Qom, Kurdistan, and East Azerbaijan. The highest and lowest total prevalence of studied parasitic zoonoses in slaughtered livestock were cystic echinococcosis (12.76%) and Taenia ovis infection (0.01%), respectively. An approximate stationary trend for fascioliasis and CE and a mild decreasing trend for dicrocoeliasis and sarcocystosis has been forecasted for the next 10 years. Forecasting the prevalence of T. ovis infection showed that without implementing control strategies, this infection would be increased in the years ahead. The current study has demonstrated for the first time the predicting of some important parasitic infections in sheep in Iran. The results provide helpful data for authorities for controlling these diseases in the frontline of meat production. Vast and in-depth forecasting investigations is required to find evidence-based data about these infections for entire the country of Iran.

Ticks’ saliva presents immunomodulatory activity and cause several tissue changes at the attachment site on the host's skin. Here, we compare different moments of the skin of a Mangalarga Marchador mare before, during and after tick attachment. On the skin with a fixed tick, we observed inflammatory infiltrate, degranulated mast cells, areas with an absence of nucleus and presence of pyknotic nuclei, type I collagen bundles are quite thick around the tick's hypostome, fibrotic process, and the occurrence of cell death by necrosis. In the skin after the tick detached, we observed a complete loss of the structure of the extracellular matrix due to the formation of edema of the inflammatory exudate, a large presence of eosinophils and macrophages, new blood vessels, and dilated vessels, indicating that in the absence of immunomodulation promoted by tick saliva, the animal's organism can start the repair and healing process.

Here, we compare different moments of the skin of a Mangalarga Marchador mare before, during and after tick attachment. On the skin with a fixed tick, we observed inflammatory infiltrate, degranulated mast cells, areas with an absence of nucleus and presence of pyknotic nuclei, type I collagen bundles are quite thick around the tick's hypostome, fibrotic process, and the occurrence of cell death by necrosis. In the skin after the tick detached, we observed a complete loss of the structure of the extracellular matrix due to the formation of edema of the inflammatory exudate, a large presence of eosinophils and macrophages, new blood vessels, and dilated vessels, indicating that in the absence of immunomodulation promoted by tick saliva, the animal's organism can start the repair and healing process.","PeriodicalId":8351,"journal":{"name":"Archives of Veterinary Science","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2022-12-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44915969","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
