AI Article Synopsis
- Rising concerns about illnesses from milk consumption are linked to contamination by pathogenic microorganisms, prompting a study on their occurrence and antimicrobial resistance.
- The study analyzed 250 samples from various sources (raw milk, cow teats, milkers' hands, milking utensils, and cow feces) and found a 40.4% detection rate of pathogenic microorganisms, with the highest levels in milk and fecal samples.
- Of the tested strains, 25.5% showed antimicrobial resistance, particularly to teicoplanin, while many were still susceptible to chloramphenicol and azithromycin, indicating high levels of cross-contamination in milk-related samples.
Article Abstract
There is a rising concern about illnesses resulting from milk consumption due to contamination by pathogenic microorganisms including This study examined the occurrence and antimicrobial susceptibility of isolated from cow milk and related samples. Furthermore, partial sequencing was done to ascertain the genetic relatedness and possible cross contamination among the samples. In all, 250 samples, that is, 50 each of raw milk, cow teat, milkers' hands, milking utensils, and fecal matter of cows, were cultured for the identification of was detected in 101/250 samples (40.4%). Milk and fecal samples recorded the highest percentages of 68.0% and 66.0%, respectively. Forty-two (42) strains examined for antimicrobial resistance showed an overall 25.5% resistance, 15.0% intermediate resistance, and 59.5% susceptibility. The isolates had a high level of resistance to teicoplanin (100.0%), but were susceptible to chloramphenicol (95.2%) and azithromycin (92.9%). The Multiple Antibiotic Resistance (MAR) index pattern ranged from 0.1 to 0.5, and 40.5% exhibited multiple drug resistance. The strains formed 11 haplotypes, and a phylogenic tree analysis showed relatedness among the isolates in other African countries. This observation is an indication of cross contamination among the milk and its related samples.

The optimization of auto parts supply chain logistics plays a decisive role in the development of the automotive industry. To reduce logistics costs and improve transportation efficiency, this paper addresses the joint optimization problem of multi-vehicle pickup and delivery transportation paths under time window constraints, coupled with the three-dimensional loading of goods. The model considers mixed time windows, three-dimensional loading constraints, cyclic pickup and delivery paths, varying vehicle loads and volumes, flow balance, and time window constraints.

Background & objectives The COVID-19 pandemic underscores the significance of vaccination in mitigating disease spread, with Covishield and Covaxin serving as pivotal vaccines in India. Breast milk, rich in vital antibodies like IgA and IgG, plays a crucial role in enhancing the immune defence of breastfeeding infants. However, limited research exists on the antibody responses in breast milk among individuals receiving single versus double doses of the COVID-19 vaccine.
