In clinical examination, it was determined that the mass had a hard and irregular surface structure. As a result of the clinical examination, it was decided to completely extirpate the mass and send it to the pathology department. The mass was widely separated from the surrounding tissues and extirpated with the help of cautery. Microscopic examination of the mass revealed that there were chondrocytes among the dense bone cell accumulations and that they formed islands in some areas. As a result of histopathological examinations, it was determined that the suspicious mass was osteochondroma. During the postoperative examinations, it was determined that there was no recurrence or complication in the patient. As a result, it was concluded that this presentation will contribute to the literature since osteochondroma masses are rare in the ear region.","PeriodicalId":442201,"journal":{"name":"Revista MVZ Córdoba","volume":"299 4","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141012450","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}

To evaluate the nutritional composition of duckweed (DW) (Lemna minor) and water hyacinth (WH) (Eichhornia crassipes) and its effect on the apparent digestibility of dry matter (%, ADDM), apparent digestibility of crude protein (%, ADCP) and the apparent digestibility of the crude lipid (%, ADCL) in the nutrition of tilapia (Oreochromis niloticus). Material and methods. The DW and WH were used to formulate nine isoproteic (32.47%), isolipidic (5.46%) and isoenergetic (16.45 MJ kg-1) diets, with three replicates and 15 male tilapia (36.36± 1.16 g) per repetition: 0% (T0); 10% (T10); 15% (T15); 20% (T20) and 25% (T25), respectively random. A principal component analysis (PCA) was applied. Results. The crude protein (%) of the WH and the DW, were 21.72% and 27.37% (p˂0.05), respectively. Fish fed with WH and DW, up to 10 and 15% inclusion in the diet, respectively, did not show significant differences (p>0.05) for ADDM. However, for ADCP and ADCL, up to 15 and 20%, respectively, significant differences (p>0.05) were not observed. Conclusions. Water hyacinth and duckweed meals were an alternative vegetable protein source, which can partially replace soybean meal and cornmeal in tilapia diets. The PCA suggests that the control diet, 10% WH, 10-15% DW, showed the best results in terms of the apparent digestibility of the nutrients.","PeriodicalId":442201,"journal":{"name":"Revista MVZ Córdoba","volume":"34 5","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141011399","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}

Determine chromosomal aberrations such as aneuploidies/polyploidies (ap/pp) of cows with a history of abortion from a municipality in Zacatecas, Mexico. Materials and methods. 107 blood samples were collected from cows with a history of abortion and ages between 3 and 10 years in the municipality of Enrique Estrada Zacatecas Mexico, a chromosomal analysis was performed with the conventional cytogenetic technique, to determine chromosomal aberrations such as aneuploidies/polyploidies. Results. The ap/pp cows range from those that did not present any aberrations (0%), a median of (2%) and a maximum of (16%) chromosomal aberrations, the recorded age of the cows was a minimum of 3.5 years, a median of 5.8 and a maximum of 7.4. With these results it can be predicted that there is the possibility that with each year a cow will abort and it increases by 31.7%. However, the p of this coefficient is 0.384—not significant. On the other hand, the possibility of a cow aborting increases by 16.5% with each unit percentage increase in the degree of polyploidy, and the p for this coefficient is 0.029, which is significant.

The objective of this review was, describe the indicators used in bovine welfare protocols, identify the domains considered, and establish a proposal focused on indicators to assess positive welfare. It was identified that the protocols require excessive evaluation times, qualify by granting a single score and do not allow regional adaptations according to the critical conditions that may exist in different countries. Furthermore, the main focus of the existing protocols is on the first 3 domains (nutrition, physical environment and health), leaving the recording of the behavior and the mental state of the animals to a lesser degree of importance. A series of indicators were specified, which would promote positive well-being, related to the domains of physical environment and behavioral interactions, emphasizing comfort, environmental, social, sensory, and nutritional enrichment.

Ophidic accidents that include ophidiotoxicosis have care protocols of therapy with antivenom serums, which vary according to the genus and species of the snake. Although in Colombia there are protocols for the care of ophidiotoxicosis in humans described by health entities, the canine clinic lacks this information. The aim of this systematic review is to build a medical protocol for ophidiotoxicosis in canines based on information reported in Colombia or tropical countries with which similar venomous snakes are shared. For this action, the PRISMA protocol was used; in total, 57 articles and 10 official documents on protocols for the care of ophidic accidents in humans were reviewed, which allowed the possible to classify snakebite accidents in group 1 (Bothrops, Lachesis and Crotalus accidents) and group 2 (Micrurus accident), also establish a medical protocol for ophidiotoxicosis in each of the groups indicated in canines, depending on the severity of the clinical and paraclinical condition. In conclusion, the clinical and paraclinical signs of the canine, vasculotoxic or neurotoxic, allow us to identify the group to which the aggressor snake belongs (group 1 or group 2, respectively), and their severity guides the selection and dosage of antivenom therapy specific for the clinical management of ophidiotoxicosis in canines.","PeriodicalId":442201,"journal":{"name":"Revista MVZ Córdoba","volume":"322 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141012498","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}

To analyze histological and immunological changes in the Pacific white snook (PWS) Centropomus viridis during primary infection and re-infection with the monogenean Rhabdosynochus viridisi. Materials and methods. Samplings were performed at three timepoints (0,1, and 2). Histological alterations in gills were evaluated by the severity degree and the degree of tissue change. RT-qPCR assays were developed to investigate the expression of il1B, il8, il10, il12, il17, igM, igT, ifnγ, tnfα, tbet, hsp70, foxp3a, stat4, and cmip in gills and head kidney. Results. The prevalence of infection was 100% in challenged fish. During the primary infection, the mean intensity was 152 parasites per fish at Time 1 and 94 at Time 2, while in the reinfection, it was 367 parasites at Time 1 and 129 at Time 2. Histological analysis of gills showed fusion of the secondary lamellae, hyperplasia, infiltration of mononuclear inflammatory cells, and increase of chloride cells in both primary infections and reinfections. Only the expression of cmip in gills at Time 1 was significantly higher in reinfections than in primary infections, and the expression of il12β showed a fold-change value >100 in head kidney at Time 2 in primary infections. Conclusions. The monogenean R. viridisi may cause histological alteration in its fish host. As showed by the decrease of the intensity of infection from Time 1 to Time 2, it seems that the PWS is able to combat R. viridisi; however, our immunological analysis did not reveal strong evidence of a possible mechanism.","PeriodicalId":442201,"journal":{"name":"Revista MVZ Córdoba","volume":"33 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-05-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141011685","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}
