To better understand the epidemiological chain of neosporosis, update the disease status and propose control measures to improve milk production in Rio Grande do Sul (RS), the present study aimed to evaluate the seroprevalence of N. caninum and its distribution in different municipalities of Rio Grande do Sul, Southern RS, Brazil, and determine the factors associated with exposure to N. caninum in small dairy cattle producers in this region. Cattle from 51 dairy farms located in nine municipalities in the southern region of RS were included in this study. Small dairy farmers were interviewed to collect information about the characteristics of their herds. The association between potential associated factors and seropositivity in cattle was assessed using a logistic regression model with a generalized estimating equation. Seroprevalence in individual animals and between herds was 33.9% (95% CI = 28.1-39.9) (121/309) and 80.4% (95% CI = 67.5-88.9) (41/51), respectively. The high seroprevalence found indicates that cattle are susceptible to exposure by N. caninum in a widespread manner in the Pelotas microregion. Furthermore, the sanitary management of cattle, the adaptation of tools that can improve the milk extraction technique and the technical monitoring of professionals who work on the properties can be effective alternatives for controlling N. caninum.","PeriodicalId":72458,"journal":{"name":"Brazilian journal of veterinary medicine","volume":"46 ","pages":"e004924"},"PeriodicalIF":0.0,"publicationDate":"2024-12-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11670822/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142900799","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Giardiasis is one of the most prevalent parasitic diseases in both developed and developing countries, with a prevalence of 0,1-5% and 20-30%, respectively, and is correlated with poor hygiene practices, such as irregular handwashing, which consequently contaminates food when handled. Cattle and sheep are sources of infection for humans due to the zoonotic potential of the species that affect them, especially calves, which play an important role in the dissemination of the parasite in the environment by excreting 106 cysts per gram of feces, contaminating water sources, which, even when treated, only reduce and do not eliminate the protozoan. This study investigated the prevalence of Giardia spp. in ruminants in the southern region of Rio Grande do Sul, Brazil. Between June 2023 and April 2024, 384 fecal samples from young cattle and sheep were analyzed, collected directly from the rectal ampulla and subjected to coprological tests at the Laboratory, used the zinc sulfate centrifugal flotation technique to visualize protozoan cysts and calculate their prevalence. The results showed that 19,15% of sheep (27/141), 13,99% of cattle (34/243) and 15.88% in both species (61/384) tested positive for Giardia spp. This study revealed a significant prevalence of Giardia spp. in young ruminants in the southern region of Rio Grande do Sul, posing an important zoonotic risk.","PeriodicalId":72458,"journal":{"name":"Brazilian journal of veterinary medicine","volume":"46 ","pages":"e006524"},"PeriodicalIF":0.0,"publicationDate":"2024-12-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC11661654/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142878736","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Clinical and radiographic findings are discussed, as well as the palatal mucosal flap surgical technique associated with the use of a synthetic polypropylene mesh. The patient was monitored for a period of six months, when close monitoring of the healing of the surgical wound was possible with adequate incorporation of the mesh into the local tissue. Although a small part of the flap showed dehiscence, there was no aspiration of food due to the presence of the polypropylene mesh under the affected region. The non-rejection of the implant, good acceptance and good eating capacity of the patient, which resulted in weight gain, must be emphasized.

Clinical examination revealed severe scalding in the perineal region and on the medial aspect of the hind limbs, along with neurological signs such as ataxia, hind limb paresis, and diminished perineal reflexes. Transrectal ultrasonography confirmed bladder distension and the presence of hyperechoic particles in the urine. Urinalysis revealed typical features of sabulous cystitis, including abundant calcium carbonate crystals. Despite treatment with corticosteroids, antibiotics, and daily bladder lavage with physiological saline, no substantial clinical improvement was observed. The limited therapeutic response and guarded prognosis were discussed with the owner, who opted to monitor the mares without altering their clinical condition for two years.

Significant creatine kinase and lactate increase in T1 associated with the maintenance of oxidative indicator levels in T1 and T18 reflected the significant muscle effort and the slight mobilization of oxidative parameters, which were compensated by the antioxidant defenses, since the assessed animals recovered after T18.

Furthermore, elastography, a technique that assesses tissue stiffness, is useful for differentiating between malignant and benign lesions. This paper describes a case of ACC in a West Highland white terrier. The dog initially presented with dermatological changes and increased adrenal tissue stiffness, as detected by elastography. After additional examinations, including computed tomography, an adrenalectomy was successfully performed. Histopathological analysis confirmed the diagnosis of ACC. Post-surgical follow-ups included periodic ultrasonography to monitor the remaining adrenal gland. A nodular lesion was identified in the left adrenal gland during the follow-up, highlighting the importance of continuous monitoring.
