Staphylococcus aureus is recognized worldwide as one of the major agents dairy cow intra-mammary infections. This microorganism can express a wide spectrum pathogenic factors used to attach, colonize, invade and infect host. The present study evaluated 120 isolates from eight different countries that were genotyped by RS-PCR investigated for 26 virulence increase knowledge on circulating genetic lineages among population with mastitis. New genotypes observed South African strains while all...
Several reports have indicated that udder surface temperature (UST) can be a useful indicator of subclinical mastitis (SCM). The objective was to evaluate UST by infrared thermography (IRT) as diagnostic tool for SCM and intramammary infection (IMI), assess the influence environmental conditions in potential diagnosis this disease dairy cows located at high-altitude tropical regions. A total 105 (397 quarters) from 3 farms with mechanical manual milking methods were enrolled study....
Group B Streptococcus (GBS), is a leading cause of neonatal death and an emerging pathogen in adults. Additionally, GBS bovine causing intramammary infections. The likelihood interspecies transmission largely unknown. We explored the potential between cattle people on dairy farms Colombia compared antimicrobial resistance (AMR) profiles isolates from both host species. Across 33 farms, throat swabs rectal were collected 191 people, composite milk samples 2092 cattle, yielding 60 human 301...
For many years Streptococcus agalactiae has been considered an obligate intramammary and strictly contagious pathogen in dairy cattle. However, recent reports of S. isolation from extramammary sources have contradicted that premise. To gain further insight into the epidemiology infection cattle, we examined its distribution heterogeneity strains bovine milk, feces, environment Colombian farms. First, a longitudinal study was conducted at herd level 152 herds. Bulk tank milk samples each...
COVID-19 is caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and has a case-fatality rate of 2–3%, with higher rates among elderly patients comorbidities. Radiologically, characterised multifocal ground-glass opacities, even for mild disease. Clinically, present symptoms, which are very similar to other virus infections. Our knowledge regarding SARS-CoV-2 still limited. These facts make it vitally important establish mechanisms that allow model predict evolution...
Selenium in vegetables, milk, and meat is a highly bioavailable source for humans; further, foods that are intentionally Se enriched can significantly enhance the consumption of by humans where intake would be otherwise suboptimal. concentration milk easily manipulated altering supply to dairy cows. Transfer from yeast more efficient than inorganic sources, such as sodium selenite/selenate. There U-shaped risk response intake, wherein supra-nutritional intakes (i.e., greater those...

Group B Streptococcus (GBS) is a major human and animal pathogen that threatens public health food security. Spill-over spill-back between host species possible due to adaptation amplification of GBS in new niches but the evolutionary functional mechanisms underpinning those phenomena are poorly known. Based on analysis 1,254 curated genomes from all six continents, we found global population comprises host-generalist, host-adapted host-restricted sublineages, which across groups,...
Introduction Bovine subclinical mastitis (SCM) caused by Gram-positive bacteria is a major cause of economic loss in the dairy industry, exacerbated situations where antimicrobial resistance present. Pure platelet-rich plasma (P-PRP) may be therapeutic alternative for SCM, when used alone or with antibiotics, such as sodium cloxacillin (SC). This study aimed 1) to evaluate efficacy allogeneic P-PRP, SC, and their combination (P-PRP+SC) cows SCM Staphylococcus aureus streptococci ( S....
The objective of the study was to evaluate premilking teat disinfectant efficacy with use a novel diagnostic protocol against positive control. evaluation based on establishing noninferiority new compared an existing disinfectant. Approximately 200 cows were randomly allocated 1 2 groups. Study personnel blinded as cow allocation and identification disinfectants. Quarters disinfected using dip cup before milking either control or experimental product. left for approximately 30 s being wiped...
Streptococcus agalactiae (SAG) is an important etiologic agent in a widespectrum of human and bovine infections. In humans, this pathogen themain responsible severe septicemia neonatal dead, due to the diseaseknown as "neonatal sepsis", which has been reported differentcountries, including Colombia. About 36% pregnant women are colonizedby bacterium them, 45% newborns acquire theSAG infection. adults, asymptomatic SAG colonization occurs frequentlyin gastrointestinal genitourinary tract....
Abstract The aims of the study were (1) to compare cure risk intramammary treatment pure platelet rich plasma (P-PRP) or cefquinome sulfate (CS) in cows with subclinical mastitis (SCM) caused by Gram-positive bacteria, evaluated via somatic cell count (SCC) and microbiological analysis milk; (2) inflammatory/anti-inflammatory response mammary gland both treatments through analyses interleukins (IL), interferon gamma (IFN-γ), tumour necrosis factor alpha (TNF-α) milk. A non-inferiority...
There is scarce information about bovine platelet-rich plasma/platelet-rich gel (PRP/PRG) and related hemocomponents (HCs), such as platelet lysates (PLs), including growth factor (GF) cytokine concentrations, how the stability of these biomolecules could be affected by time temperature. This study aimed to evaluate release transforming beta 1 (TGF-β1), interleukin 4 (IL-4), tumor necrosis alpha (TNF-α) contained in pure PRP (P-PRP) temperature-induced PL (TIPL) coming from a similar...
