Well they are both pathogenic
No, not all pathogenic bacteria are gram-negative. Pathogenic bacteria can be either gram-negative or gram-positive, depending on their cell wall structure. Some common gram-negative pathogenic bacteria include Escherichia coli, Pseudomonas aeruginosa, and Neisseria meningitidis, while some gram-positive pathogenic bacteria include Staphylococcus aureus, Streptococcus pneumoniae, and Enterococcus faecalis.
Gram staining is highly valuable. It allows us to identify two widely different bacteria. Gram staining can tell you if the bacteria is pathogenic or if a penicillin pill can cure it. It tells us gram-positive bacteria, or gram-negative. Positive being easily combated bacteria and some even helpful, and gram-negative being primarily pathogenic.
Just about any - gram negative, gram positive and acid-fast are all known to have pathogenic bacteria within them.
The disease causing bacteria are called pathogenic bacteria.They are generally gram negative but can also be gram positivee.g. of pathogenic bacteria are :SalmonelllaPseudomonasClostridiumAnthracis etc.

i believe it is a gram bacteria which causes respiratory illness.
Gram positive
We hear more about Gram-negative pathogens (E. coli, Salmonella, etc.) because they make good news stories and are generally associated with transmission in improperly handled or prepared food. However, there are many pathogenic Gram positive bacteria as well - Staphlococcus (including MRSA), Streptococcus (such as strep throat), etc. Also, there are many Salmonella species that are non-pathogenic, as well as non-pathogenic E. coli, Enterobacteraceae, etc. So I'm not sure that most Gram negative bacteria are pathogenic.
Gram-negative bacteria have a thinner peptidoglycan layer in their cell walls compared to gram-positive bacteria. Additionally, gram-negative bacteria have an outer membrane that contains lipopolysaccharides, which is absent in gram-positive bacteria.
Gram-positive bacteria and Gram-negative bacteria are different in their colouration when dyed and viewed with a light microscope. Gram-positive appear violet, and Gram-negative appear red. Gram-positive and Gram-negative classification, however, has nothing to do with size.
Name of gram positive and gram negative bacteria?
Tetracycline kills both gram positive and gram negative bacteria. The mode of action to which Tetracycline works to kill bacteria is that it inhibits protein synthesis which works against both gram positive and gram negative bacteria.
