There are no studies regarding the efficacy of azithromycin (AZ) and of any combination of trypsin, chymotrypsin, and papain proteolytic enzymes (PEC) in the treatment of BCP. The objective of this study was to investigate the efficacy of AZ and PEC in the treatment of BCP. A total of 24 female Holstein cattle of 6-17 months of age with spontaneous BCP were used for this study. In addition to the clinical findings, the diagnosis was confirmed with histopathological examinations. The animals were divided at random into three groups (n = 8). The AZ group received 10 mg/kg/day PO for 10 days. In the PEC group, an injectable suspension of proteolytic enzymes was applied IM at 0.4 mL/10 kg dose, 3 times with 8-10 days interval and the spray was used topically once a day for 10 days. The control group (CO) was not treated. The mean in papilloma warts decreased 92.4 % in the AZ group, 83.38 % in the PEC group, and 59.48 % in the CO. There were statistically significant differences in warts presence decreases between the three groups (P < 0.05). Both AZ and PEC were considered successful for the BCP treatment. However, AZ was found more effective than PEC.","PeriodicalId":56044,"journal":{"name":"Veterinaria Mexico","volume":" ","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45520655","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study assessed the impact of fermented and non-fermented soybean and canola meals on growth performance, in vivo and in vitro digestibility, digestive enzyme activities and meat quality of Litopenaeus vannamei. A total of 513 shrimps were randomly assigned to treatments (control and two experimental diets). Animals on the control diet (cd) were fed a commercial feed concentrate. For the other treatments, the fishmeal protein source was totally replaced by a mixture of soybean and canola meal (50:50), either unfermented (sc) or fermented (fsc). Results showed that fermentation significantly increased (P < 0.05) the hydrolysis degree (hd) of sc meals by 12 % compared to that of their unfermented counterparts. Also, it was found that canola meal had higher hd compared to soybean meal, both before and after fermentation. The use of sc diet decreased protein digestibility in shrimps (P < 0.05), although there was no significant variation in the activity of total proteases and chymotrypsin. Production performance traits of shrimps fed diets with fsc were comparable to those of shrimps on the control diet. The increase in shear force of shrimps fed fsc was accompanied by an increase in the water holding capacity (whc) by 8-9 % (P < 0.05). Sensory attributes were similar across diets. In summary, this study showed it is possible to fully replace fish meal with fsc in shrimp diets without impairing production performance traits, dietary protein digestibility, and shrimp meat quality.","PeriodicalId":56044,"journal":{"name":"Veterinaria Mexico","volume":" ","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-05-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"46387304","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Hundred domestic cats with clinical manifestations of diseases associated with feline retrovirus infection in veterinary centers in Mérida, were submitted to a general physical examination, venipuncture to collect blood, and a quantitative hemogram. Detection of antigen (FeLV) and antibody (fiv) was used to estimate infection frequency. The percentage of regressive FeLV infections was determined by pcr of an env gene segment. Some FeLV amplified products were sequenced with the Sanger method and used to construct a phylogenetic tree. The predominant FeLV and fiv clinical infection findings were gingivitis, gingivostomatitis, periodontal disease and anemia. We found a 10% infection frequency for FeLV by antigen detection, and 17% for fiv by antibodies detection. pcr frequency detection for FeLV was 58%, and 52% were regressive infections. The phylogenetic analysis identified sequences associated with FeLV-A, and endogenous or recombinant FeLV that had not previously been identified in México. The frequency of infection by both retroviruses was higher in Mérida, Yucatán, than those described in previous studies. Cats with FeLV predominantly had regressive infections, but the role that endogenous or recombinant retroviruses play in disease development remains unknown.","PeriodicalId":56044,"journal":{"name":"Veterinaria Mexico","volume":" ","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-03-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42920772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study evaluated a feed formulated with wheat (Tritium sativum) and chickpea (Cicer arietinum) enriched with spirulina (Spirulina maxima) for shrimp Litopenaeus vannamei farming. A feed based on wheat and chickpea (2.5:1) containing 3% spirulina was developed and characterized by proximal chemical analysis. The experimental feed was evaluated along with a commercial feed in a five-week field bioassay to determine the growth, survival, and health status of the juvenile shrimp. In addition, water salinity (mg·L-1) was monitored as an environmental stability factor for shrimp cultures. The proximal chemical composition of the experimental feed contained 17.5 ±0.1% protein, 2.2 ±0.3% lipids and 68.0 ±0.3% carbohydrates. The specific growth rate (0.22 ±0.05 g·days-1) of the shrimp under experimental feed did not show statistical differences in comparison with the commercial feed (P> 0.05). Also, it was determined that the shrimp fed with experimental feed presented a biomass production (0.74 ±0.17 g), survival rate (>98%) (P <0.05) and health status better than shrimp fed with commercial feed.

This study is aimed to determine the movement and feeding habits of pig groups raised under semi-confinement conditions, using minimally invasive procedures, applying trajectory analysis to different herds in rural settings. Pig population and subpopulations were characterized, and their movement was evaluated in two seasons of the year, using a global positioning system (GPS). Our results indicate that pig groups are formed based on human ownership and the establishment of family bonds with each other. Each group interacts with other groups in specific sites of the village. Significant differences were found in the time and distance covered by pigs in the dry and rainy seasons (P < 0.05), and the distance travelled by different groups were found to take place in repetitive, well-defined spaces that include moving through sewage, landfills, and open defecation sites.

Numerous studies have been published since the SARS-CoV-2 outbreak began in Wuhan, China. Most have focused on virology, epidemiology, pathogenesis, and therapeutic medicine, having been centered by reactive strategies to control the pandemic. Meanwhile, publications addressing the ecological, evolutionary, and anthropogenic drivers of virus emergence, and potential strategies to prevent future outbreaks have been sparse. Here, we highlight the necessity of complementary and transdisciplinary insight and methodologies from an integrated perspective to study emergent diseases. It is paramount to situate the consistently associated factors to understand the complexity of the current pandemic. Disease ecology can examine information to recognize the causes of emergence while appraising the role of interactions among pathogens, domestic animals, wildlife, and humans, integratively. Here we draw on a variety of disciplines and perspectives, from evolutionary biology, biogeography, ecology, molecular epidemiology and integrative health, to address the emergence of coronaviruses, with particular emphasis on SARS-CoV-2. We describe the process of the surfacing of zoonotic diseases, highlighting the interactions among wildlife, domestic animals, and humans, as well as the genetic, evolutionary, ecological, and anthropogenic processes that favor coronavirus epidemics and epizootics. We discuss specific results related to coronavirus investigations conducted in Mexico based on disease ecology methodologies. Finally, we describe alternative approaches for understanding and preventing future outbreaks and we suggest strategies to entice integrative and transdisciplinary research within the One Health/Ecohealth paradigm.","PeriodicalId":56044,"journal":{"name":"Veterinaria Mexico","volume":"8 1","pages":""},"PeriodicalIF":0.2,"publicationDate":"2021-05-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44483880","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Vaccination programs in Mexico use commercially available Fowlpoxvirus vaccines, that are used across different bird species. Nonetheless, there are reports of sporadic disease outbreaks among vaccinated turkeys, which suggest that heterologous vaccines may provide limited immunity, presenting the need to develop homologous vaccines that can better protect turkeys. This study compared the protection granted to turkey chicks by a commercial Fowlpoxvirus vaccine and by a live attenuated Turkeypoxvirus vaccine after a challenge with a field isolated Turkeypoxvirus virus. Histopathology, polymerase chain reaction, and sequencing of DNA were used for viral identification. A Turkeypoxvirus strain was first isolated in chicken embryo lesions, and subsequently adapted through serial passes in chorioallantoic membrane to produce the homologous vaccine. The attenuated virus was used as a vaccine when a 104.4 embryo ID50/mL titre was reached. Three groups of three-week-old turkey chicks were used for challenge experiments. Subjects in Group 1 were immunized with the attenuated Turkeypoxvirus vaccine (homologous vaccine). Chicks in Group 2 were vaccinated with the commercially available heterologous vaccine (Fowlpoxvirus). Subjects in Group 3 were not vaccinated and received only saline solution (control group). Two weeks after vaccination, animals from Group 1 reached a 97.7 ND50 seroneutralization titre, while levels reached in Group 2 birds and in control chicks were 11.7 ND50 (Group 2) and zero, respectively. At this time, all groups were challenged with a suspension of a field-isolated Turkeypox virus. The homologous vaccine afforded 100% protection in Group 1 (10/10 individuals), while only 10% (1/10) of individuals in Group 2 were protected by the commercial heterologous Fowlpoxvirus vaccine. None of the non-immunized birds in Group 3 were protected (0/10). These results show that the homologous vaccine afforded a greater protection against a Turkeypox virus infection than that observed for the heterologous vaccine, and that a homologous vaccine can be efficiently produced by isolating and attenuating the virus from turkeypox lesions, through chorioallantoic membrane serial passes.","PeriodicalId":56044,"journal":{"name":"Veterinaria Mexico","volume":" ","pages":""},"PeriodicalIF":0.2,"publicationDate":"2020-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44700561","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
