Currently, the overpopulation of these species in various countries worldwide has been identified as a severe public health problem. To establish effective programs for population control, it is necessary to estimate the number of cats and dogs. To our knowledge, there are no studies that assess the number of canine and feline population by state in Mexico. Therefore, this study aimed to estimate the canine and feline population living at homes using official information reported by the National Institute of Statistics, Geography and Informatics [Instituto Nacional de Estadística Geografía e Informática] through a constant-share model, a ratio extrapolation method. The estimated dog population living at homes was 42 625 010 dogs and 7 346 925 cats (at least 5.8 times less than the number of dogs). By 2022, the Mexico's estimated human:dog ratio was 2.4:1, and the human:cat ratio 17.6:1. The Estado de México had more than six million dogs and 962 177 cats. Colima had the smallest estimated dog population (245 489), and Baja California Sur the smallest estimated cat population (slightly over 30 000). Health authorities and veterinary practitioners should promote responsible ownership to increase veterinary care and control the birth of dogs and cats.","PeriodicalId":56044,"journal":{"name":"Veterinaria Mexico","volume":" ","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41795851","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}

Thus, we used meta-analyses to estimate the prevalence of carcass bruising in cattle from the American continent, determined the characteristics of the bruises, and calculated the odds ratio (OR) of risk factor categories associated with bruising. We searched electronic databases to retrieve primary studies conducted in the American continent, which reported cattle carcass bruising, analyzed the size, location, shape, and age of the bruises, and assessed risk factors for bruising. We included 46 studies from nine countries comprising 928 447 cattle carcasses with an overall prevalence of 59.5 % (95 % CI: 51.9 – 66-9) and 2.9 (range 3.4 – 7.4) bruises per carcass in average. The prevalence doubled from 30.7 % during 1991 – 2000 to 64.2 % during 2011 – 2020. Fresh, small-sized bruises of the lowest severity and located mainly in the hindquarter were highly prevalent (37.5 – 66.4 %). The removed meat due to bruising ranged 0.11 – 1.12 kg/carcass with an accumulated weight of condemned meat between 15.6 – 647 kg. Among intrinsic factors, older cattle, dairy cattle, and female cattle had greater odds of bruising (OR=1.57 – 1.98). For extrinsic factors, the odds for bruising increased 1.4 – 2.2 in cattle sourced from auction markets and exposed to poor handling, suboptimal transportation conditions, and deficient facilities. In cattle from America, bruises are a concern because their prevalence is growing and 60 % of cattle assessed in the studies suffered a bruise. Improving facilities and transportation conditions together with proper training of the personnel during the handling and transportation of the cattle will reduce bruising incidence.","PeriodicalId":56044,"journal":{"name":"Veterinaria Mexico","volume":" ","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-10-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"45584104","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}

The purpose of this study was to detect STEC O157 and non-O157 in meat products from Federal Inspection Type (FIT, n=52) and non-FIT (n=88) slaughterhouses, as well as butcheries (n=50), in southern Sonora, Mexico. To achieve this aim, selective media were employed to obtain putative O157:H7 colonies (TS-SMAC agar and Rainbow® agar O157), followed by multiplex PCR for the stx1, stx2, eaeA, and rfB genes, using the O157:H7 serotype as a control. No STEC O157 was found in beef products, but some non-O157 isolates were found containing the stx2 pathogenicity gene (1.40%, 3/224) and/or the fliCH4 flagellar antigen (1.78%, 4/224). This work also confirmed the susceptibility of strains with the stx2 and/or fliCH4 genes to several antibiotics and multi-resistance of all or some of these strains to trimethoprim/sulfamethoxazole, tetracycline, clarithromycin, penicillin G, oxacillin, ampicillin and cefazolin.

The sugar content was determined by highperformance liquid chromatography (HPLC) with a refractive index detector, and °Brix was determined using a refractometer.

Using next-generation sequencing, thirteen samples of RNA from the field sampled cloacal swabs were subjected to whole genome sequencing. Seven whole IAV ge-nomes were obtained, while remaining six samples provided partial results. Eight different hemagglutinin (HA) and neuraminidase (NA) combinations were identified in analyzed samples, while the analysis of the remaining genes in seven whole genome samples demonstrated four different combinations of viral segments, suggesting a diversity of circulating IAV. Phylogenetic analysis of samples whose whole genomes were sequenced showed that they are closely related to North American IAV, with some segments (NP, H6 and H11) related to the Eurasian virus.

{"title":"Effect of the administration route of gonadotropin releasing hormone on the reproductive performance of multiparous Holstein cows","authors":"Sirous Mozaffari, M.

Cows (n = 117) were randomly allocated to treatment and control groups. In groups IM0, IM7, and IM07 (n = 12 per group), cows received GnRHa intramuscularly (IM) at 0 or 7 days, or both, respectively. In groups EP0 (n = 19), EP7 (n = 13) and EP07 (n = 11), cows received GnRHa at the sacrococcygeal epidural site (EP) at 0 or 7 days, or both, respectively. Animals in the control group (CON) received 5 mL of normal saline at 0 and 7 days. Pregnancy diagnosis was performed by rectal palpation of the uterine horns 60 days post AI. Results showed a significant difference in PR/first AI between IM0 and EP7 groups (16.67% vs. 61.54%; P < 0.05). Moreover, the results showed no significant differences in overall PR after two rounds of inseminations among all groups 60 days after the second AI. In conclusion, epidural injection of GnRHa 7 days after AI versus its intramuscular injection at AI improved PR/first AI significantly in Holstein lactating cows.","PeriodicalId":56044,"journal":{"name":"Veterinaria Mexico","volume":" ","pages":""},"PeriodicalIF":0.2,"publicationDate":"2022-08-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"48328038","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}
