Cow milk samples were collected during three periods and from four milk collection centres located in four different geographical zones. Samples were analysed for their standard plate count, enterococci, total coliform and feacal coliform, lactic acid bacteria, spoilage bacteria and some of the pathogenic bacteria. The most contaminated cooperatives were those located essentially in the irrigated zones. The less contaminated ones belong to semipublic farms. It seems that transportation, milking and pre-storage conditions constitute the main basic relevant factors for heavy bacterial contamination. This is the first survey of the microbiological characteristics of raw milk produced in the Tadla area of Morocco. [ABSTRACT FROM AUTHOR]

We have read with great care and interest the article by Li et al The authors provide interesting elements with respect to the possible entry of severe acute respiratory syndrome coronavirus 2 at the brain area and plead for an implication of the central nervous system in respiratory problems linked to coronavirus disease. Here we provide additional elements that support those observations, notably the role of brainstem structures located in the medulla oblongata in modulating respiration. We also discussed the possible pathways the virus uses to cross the brain blood barrier and reach the brainstem. Research Highlights: Precise anatomical evidence concerning the eventual involvement of gelatinous nucleus located in the medulla oblongata in the breathing failure observed in severe infected COVID‐19 patients.CVO as strong possible entry route of SARS‐Cov‐2.

We have studied the developmental patterns of vasoactive intestinal polypeptide (VIP) binding sites in the human hypothalamus. VIP recognition sites were widely distributed throughout the rostrocaudal extent of the hypothalamus. VIP binding was generally low in the fetal and neonatal periods and a tendency in increasing densities was observed during postnatal development. The age comparison of binding density indicates variations in several structures. Thus, the densities were higher in older infants in the preoptic area, lamina terminalis, and infundibular (IN) nucleus. These differences suggest the implication of VIP receptors in the development of this brain structure and the maintenance of its various functions. [ABSTRACT FROM AUTHOR]
