    This longitudinal study characterized Salmonella circulating in lymph nodes (LN, n = 800) and beef trimmings (n = 745) from slaughter cattle from a Mexican feedlot. During two years, LN and beef trimming samples were collected 72–96 h post-slaughter, and we obtained 77 isolates of the serovars Anatum (n = 23), Reading (n = 22), Typhimurium (n = 10), London (n = 9), Kentucky (n = 6), Fresno (n = 4), Give, Muenster, and monophasic 1,4,[5],12:i- (n = 1 each). These isolates were subjected to whole genome sequencing, single-nucleotide polymorphism (SNP)-based phylogenetic analysis, reconstruction of their ancestral isolation sources through evolutionary analysis, and virulence profiling. Although LN and beef trimmings were not mixed, evolutionary analysis estimated that the common ancestor of all study isolates was likely of LN origin. Moreover, isolates from both sources were highly clonal (0–21 SNP distance), highlighting the complexity of Salmonella transmission dynamics. The pathogen persisted across cattle cohorts, as shown by clonality between isolates collected in different years (1–20 SNP distance). Major virulence genes were highly conserved (97–100% identity to the reference sequences) and most isolates carried a conserved version of pathogenicity islands 1–5, 9, 11, and 12. Typhimurium strains carried the Salmonella plasmid virulence operon (spvRABCD), and a Muenster isolate carried the st313td gene, both of which are associated with invasive phenotypes. Most isolates (49/77) were genetically similar (1–43 SNPs) to strains involved in human salmonellosis, highlighting their public health significance. Further research is needed on Salmonella transmission dynamics in cattle and the mechanisms determining subclinical infection and persistence in farm environments.

    BackgroundLeptospirosis is a zoonotic disease and a challenge to global public health. There is an occupational risk, particularly in populations with direct contact with animals and in high‐humidity environments, which favors the survival of leptospires. This study aimed to determine the seroprevalence of leptospirosis in military personnel working in close contact with animals in México and to describe the available preventive measures and protection levels.MethodsA cross‐sectional study was conducted from March to October 2015. Information regarding protective factors in daily activities was gathered through a self‐evaluation questionnaire. The serum samples of participants were analyzed through enzyme‐linked immunoassay (ELISA) and microscopic agglutination test.ResultsSerums were obtained from 65 active military personnel, 56 males (86.2%) and 9 females (13.8%). Out of the total, 54 (83.1%) tested positive for infection by leptospirosis, 49 were males (87.5%) and 5 were females (55.6%). The highest seroprevalence age group was in the ≥45 years group (15, 23.07%), where all tested positive. Regarding military ranks, 100% of the highest hierarchy turned out positive: Officers (4 out of 4) and Chiefs (14 out of 14); and troops resulted in a seroprevalence of 76.5%. Protection equipment available during daily chores included: Overall, 64.6% had gloves and 53.8% had boots; the reported frequency for the use of gloves was 35.3% (46/65) if worn during more than half of the workday, yet 29.2% (19/65) reported never wearing them.ConclusionsThis study makes the petition to implement protocols of continuous training regarding labor risks and having an epidemiologic surveillance program for exposed personnel indispensable to improve the health and sanitary conditions of military personnel who work in direct contact with animals.

    This work performed a descriptive analysis of the quality of shampoos for use in dogs that are marketed in Mexico City. Up to now, there is a lack of information in this regard, which is important to facilitate the selection and recommendation of these products by veterinary professionals. Products of 20 commercial brands were studied, to which physicochemical, sensory and performance tests were carried out, in addition to evaluating the content of their labels. The pH of the shampoos varied between 5.6 and 8.4; the viscosity, between 1 131 and 3 102 m Pa-s; the relative density, between 1.002 and 1.099 g/mL and the foam rate between 2.9 and 4.0 min. 95 % of the shampoos formed a closed foam, between 10 and 35 % of the brands presented deficiencies in the labeling. Generally, the physical-chemical and sensory properties of the shampoos brands under study are within the acceptable limits for the line of use in humans. However, the lack of consistency in labeling suggests that it is necessary to improve the supervision of applicable regulations to protect animals and public health.

    Cats and dogs have a very close relationship with humans. 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.
