The objective of the research was to determine the sensitivity to antimicrobials of Streptococcus spp. from milk samples from lactating cows positive to California Mastitis Test in the dairy farms mentioned in 2018. For this purpose, 200 bovine were counted, of milk aptitude, in lactation, without distinction of race or age, of which 141 (70,5%) were positive to the California Mastitis Test (CMT). The positive samples were identified, refrigerated and sent to the laboratory of the Department of Microbiology and Immunology of the Faculty of Veterinary Sciences of the National University of Asunción, where the corresponding microbiological analyzes were performed. The laboratory results obtained indicated that of the 141 samples analyzed in 89 (63,12%), bacterial microorganisms were isolated; 26 (29,21%) corresponding to Streptococcus spp.; of which 2 (7.69%) were sensitive to oxaciline; 19 (73,08%) to cefotaxime; 26 (100%) to penicillin; 22 (84,61%) to erythomycin; 25 (96,15%) to clindamycin; 24 (92,30%) to chloramphenicol; 15 (57,69%) to tetracycline; 22 (84,61%) at teicoplanine and 25 (96,15%) were sensitive to rifampicin.","PeriodicalId":33906,"journal":{"name":"Ciencia Veterinaria","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67728159","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}

The dirofilariosis occurs in warm areas, with moisture, beeing the mosquito the vector responsible for its transmission. Despite its denomination, it is a mainly pulmonary disease, affecting the cardiac part in advanced stages. It has different larval stages, but stage L3 is infectious. It enters the host through the vector bite and begins to develop to adult stages which are located at the pulmonary arteries. The main definitive host and reservoir is the dog, but it can affect other wild canids like the fox. The clinical signs range from exercise intolerance, coughing, respiratory crackles and as the parasitic load progresses and increases, hemoptysis or epistaxis, weight loss, syncopes, may occur. In order to arrive at its diagnosis, the detection of microfilariae is essential, whether by taking blood smears from microhematocrit tubes or by the Knott test. Its treatment consists in, the elimination of the young filariae by the administration of macrocyclic lactones and then the use of an adulticide drug, melarsomine diclohydrate. The climatic changes that have occurred in the last time are of concern due to their propagation towards the north of Patagonia, and particularly to our province of La Pampa.","PeriodicalId":33906,"journal":{"name":"Ciencia Veterinaria","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48498310","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}

The present trial was carried out on a beef farm with 320 British crossbreed cattle, at Toay Department, La Pampa. During a period of five years, a protocol as following was implemented: three-time estrous synchronization followed by fixed-time artificial insemination plus natural mating until the end of the breeding period. The protocol used for artificial insemination started 40 days post-partum and each cow was classified by a colour ear tag and by probable date of delivery. At day zero, an intra-vaginal progesterone dispositive (0.5 g, i.v., Dib, Sintex S.A., Argentina) was placed to all cows in combination with an estradiol benzoate dose, when the dispositive was removed, after 7 days, the animals received a dose of prostaglandin (Cloprostenol, 2 cc., i.m., Ciclase DL, Sintex S.A.) and estradiol cypionate (1 mg, i.m. Cipiosyn, Sintex S.A., Argentina), to finally be inseminated at day 9. Thereafter, the protocol finished with the incoming of 5% of bulls until the end of the predetermined breeding period. The pregnancy percentage of both cows and heifers increased through the study period to values of 90 and 91%, respectively. 70% of parturition was concentrated during the first month, 23% in the second and just 3% during the last month of calving season. The  suggested system allows increasing the reproductive efficiency of the cattle herd, achieving both a higher percentage of early pregnancy and increasing interparturition interval allowing a better recovery of the reproductive tract.","PeriodicalId":33906,"journal":{"name":"Ciencia Veterinaria","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43345354","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}

The aim of this study was to determine if the protective effect of indomethacin (ID), a non-steroid anti-inflammatory drug, on the gastric mucosa, is mediated by prostaglandin. The animals were assigned into one of the six groups of five animals each. The Blank Group (BG) received an oral dose (OD) of an excipient (Ex) composed of hydroxyl methyl cellulose and tweed 80; the Control Group (CG) received excipient plus 5 mg/kg subcutaneously of ID; the Equisetum Group (EG) with EE; the Equisetum Indomethacin Group (EIG) with EE and ID; the Cortaderia Group (CoG) with Eco and the Cortaderia Indomethacin Group (CoIG) with Co and ID. The doses DOI: http://dx.doi.org/10.19137/cienvet-201921103 45 utilized in the animals were obtained from 1 gram of dried aerial plant parts extracted with ethanol-water (1:1; v/v) and re-suspended with Ex until 0.5 ml. The ID groups (CG, EIG, CoIG) received the doses 1 hour before the beginning of the trial, and thereafter all the groups were subjected to stress during 4 hours at 22 °C. In order to assess the gastric harm, the percentage of ulcer inhibition was calculated as follow [(AUControl or Blank Groups – AUTreated Group/AUControl or Blank Group) x 100] where AU is the Ulcerated Area . The administration of ID induced a higher degree of gastric damage in the CG than in the BG (p≤0.01). The EE administration prevented the gastric damage in four mice of the EG, but the administration of ECo prevented the damage in all the animals of the CoG (p≤0.01), demonstrating no gastroprotective effect of EE when was given concomitantly with ID. The ECo showed significant gastroprotective effects when was administered simultaneously with ID (p≤0.01) suggesting that prostaglandin would have no effect in the protection of the gastric mucosa. The findings of vegetable drugs with the observed actions are of interest in order to both replace drugs with an antagonist of H2 and inhibitors of protons pump actions, because of its side effects when are prescribed during an extended period of time.","PeriodicalId":33906,"journal":{"name":"Ciencia Veterinaria","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67728058","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}

With nitrogen fertilization in the pasture, it is possible to handle the Raigras ‘Winter star’ grasses with an average height of 12.5 cm.
