Las infestaciones por NGI constituyen una limitante de alto impacto en la producción de rumiantes y las perdidas comprendidas por este problema sanitario varían desde reducciones subclínicas en la ganancia de peso hasta la muerte de animales con altas cargas parasitarias. El objetivo de este trabajo es presentar los resultados de un test de eficacia a campo utilizando una combinación comercial de Abamectina + Derquantel y del Moxidectin en cabras lecheras naturalmente infestadas con NGI en el Valle de Lerma, provincia de Salta. El ensayo se llevó a cabo en la Unidad Tambo Caprino de la Estación Experimental Agropecuaria Salta del INTA. Para la evaluación de eficacia de la droga en estudio, se realizó el test de reducción de conteos de huevos. En los coprocultivos pre-tratamientos se pudo observar una gran prevalencia de Trichostrongylus spp. (71%). seguido de Teladorsagia spp. (21%) y Haemonchus spp. (8%). En cuanto a los resultados del TRCH, en el GDQ se observaron valores del 100% de PRCH, mientras que en el GMX se observó un PRCH de 95,5 %, donde la eficacia para Haemonchus spp. y Teladorsagia spp. fue del 100% y para Trichostrongylus spp. del 81,1%.Los resultados observados en este trabajo permiten concluir que en las condiciones de campo en donde fue llevado a cabo el TRCH, la combinación Derquantel-Abamectina posee una alta eficacia contra los géneros presentes","PeriodicalId":30802,"journal":{"name":"Fave Seccion Ciencias Agrarias","volume":"87 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87238559","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 statistical analysis of the results obtained by this technique is standardized by the FAO who proposes the use of the Probit model. However there are alternative mathematical models that allow a more precise analysis of experimental data generating more information as nonlinear logistic equation, also called the Hill model. The results of the IVM efficacy against a sensible strain of R. microplus were analysed whit both model. A comparison between the results obtained with PROBIT and Hill model showed that the last one was able to make a more precise fit of the experimental data, generating more information about small IVM concentrations. The C50 (13.58 ppm) obtained with Probit model result smaller than the obtained with the Hill model (14.24 ppm), however the C90, C99 and the discriminant dose (19.31 ppm, 25.74 ppm, 51.48 ppm) obtained with de Hill model were bigger than the obtained with the Probit model (17.50 ppm, 21.98 ppm, 43.96 ppm).","PeriodicalId":30802,"journal":{"name":"Fave Seccion Ciencias Agrarias","volume":"43 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90563119","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}

Marbofloxacin was administered to six 3-week-old goats by subcutaneous route at the dose of 2 mg/kg. The pharmacokinetic parameters were estimated by non-compartmental analysis. The dose of MFX capable to protect the 95% of population was calculated considering the population distribution of pharmacokinetic parameters. The efficacy of MFX was evaluated by the relationship between the area under curve and MPC (AUC/MPC) with a cut-off value of 22 h. The results showed that the estimated dose of MFX to reach the clinical outcome of gastrointestinal infections caused by E. coli and to prevent the bacterial resistance at the 95% of the population of 3-week-old goats was 3,179 mg/kg, which for practical reasons was fixed at 3,5 mg/kg.

In this study, the hormesis phenomenon on the antibacterial activity of honey was assessed. The activity of four honeys (A, D, C and D) were checked by agar plate diffusion method using S. aureus (ATCC 29213) as the test organism. Each honey was tested as follows; on the surface of an agar plate, five stainless steel cylinders with a diameter of 8,14 mm were radially disposed. Onto each cylinder 0,1 mL of the sample honey diluted in water at 50 – 25 - 12,5 -6,25 and 3,125 % v/v were placed. Plates were incubated at 35°C during 24 h. The surface of the cylinder diameter was set as reference antibacterial activity (Ra). The antibacterial activity of each honey was quantitated by the relationship between the surface of the inhibitory zone (Iz) and the surface of the reference activity (Iz/Ra). An increase in the antibacterial activity was observed at a concentration of water greater than 50% in honeys B and C. This hormetic behavior could be considered as indicator of the quality of the antibacterial activity of these honeys.","PeriodicalId":30802,"journal":{"name":"Fave Seccion Ciencias Agrarias","volume":"197 1-2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"72470086","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}

L. plantarum LP1, LP3, LP5 and LP7 of porcine origin and a reference strain of Campylobacter coli NCTC 11366 were used. C. coli and L. plantarum was reactivated. Lyophilized ELC and ELCn were obtained. C. coli was distributed on the surface of mCCDA by swab and the ELC and the ELCn were inoculated in wells previously made on the agar. After 48 h, the diameter of the zone of inhibition was measured. The inhibition halos produced were 23.2 mm. The ELCn showed less antagonistic activity. The LP5 ELC generated higher inhibition halos and ELCn showed no differences between the four strains studied. L. plantarum strains, isolated from the pig production chain, could potentially be applied to control C. coli. This data is added to the scarce scientific evidence of the inhibitory effect of L. plantarum before this zoonotic pathogen of importance in public health.","PeriodicalId":30802,"journal":{"name":"Fave Seccion Ciencias Agrarias","volume":"177 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"76432795","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}

In this study, using Franz-diffusion cells the in vitro permeation rate through respiratory and olfactory equine nasal mucosa of two butorphanol formulations was estimated and compared. Both formulations had the same composition, was the exception for formulation 2, that contained 2, 5 x 10 -4 M of a non-ionic surfactant (tween 80). Butorphanol administered dose was 24, 4 mg/cm2. Plots of the cumulative amounts of butorphanol against time were constructed, where maximum flux values at the steady state (Jss), apparent permeability coefficients (Kp) and lag-time (tlag) were estimated. The Jss and Kp show that permeation of butorphanol through olfactory mucosa is different than respiratory mucosa. Moreover, Jss for formulation 2 was higher than formulation 1 in both anatomical areas, probably for the effect of the surfactant. The present results are promising to carry on with the development of formulation of butorphanol for intranasal administration.","PeriodicalId":30802,"journal":{"name":"Fave Seccion Ciencias Agrarias","volume":"92 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85845137","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}
