Let me help some chemists and biologists ;- gram positive bacteria thrive in an acid ph environment and are by far the most common' and are acid resistant externally;
note;- gram negative' bacteria ie Gram-negative bacteria are a group of bacteria that do not retain the crystal violet stain and importantly prefer alkali environments although they are still found in environments where hydrochloric acid is intermittently' in use at levels less than 2% example the stomach and upper bowel; an example pylori bacta' or Wolbacia bacteria;
male mosquito's have blood that is biased to acid ph and female mosquito's have blood biased to alkali' so cells in female mosquito's are not inhibited very much by wolbachia' bacteria which is gram negative'
note;- where as male mosquito's have an acid biased blood of which wolbachia does effect cell chromsomes of viruses' which in tern mating offspring is also is affected'
Note it is the Toxins of Wolbachia that cause microcephaly because the toxins alter chromosomes in neurons' in mosquito's and humans' example;- in the fetus some neuron mitosis simply does not occur so the neuron dies and so brain formation is affected in the fetus; result at worst microcephaly but usually more subtle damage causing poor brain glial cell connections' so therefor brain operation is impaired to the point of temporary signal failure or signal overload in incorrect areas of the brain causing brain seizures and epileptic fits; or just generalised mild encephalitis; note the female uterus is an alkali environment for the zika virus accompanied & infected with Wolbachia Toxins' ie the entire complex viral amino chain'
Maintaining an alkaline environment in the uterus is vital for conception' so note;- the female uterus is a prime launch pad for Zika associate Wolbachia toxin produced Microcephaly and associate brain trauma defects;
