  Causes of bacterial meningitis:      Streptococcus pneumonia   (causing pneumococcal meningitis)    Neisseria meningitidis   (causing meningococcal meningitis)     Haemophilus influenza   type b (Hib ) Newborns are usually infected with coliform (bacteria in the gut, contracted at birth) such as Escherichia coli   or  Listeria .     Toxoplasmosis  (also known as toxo) is caused by the parasite  Toxoplasma gondii .  Cerebral cysticercosis  is caused by the pork tapeworm. The infestation is acquired when people eat food contaminated by feces or eat the larvae. This disease has recently become relatively common in the southwestern U.S.    Trichinosis  is caused by the roundworm  Trichinella spiralis . It is acquired by eating larvae in raw or undercooked pork. \    Cerebral abscess  is often a complication of chronic sinus or middle-ear infections or the distant spread of the infection from somewhere else (such as a lung abscess or  pneumonia). o   Spinal abscess  is caused by various bacteria. o   Poliomyelitis  ( polio) is caused by a small  poliovirus.  o   Rubella  (German measles) is caused by the rubella virus. from getting rubella, which is especially important during pregnancy. o   Mumps  and measles  are both caused by viruses. Young children are most commonly affected. o   Rabies  is another  viral infection. It is transmitted to humans by the bite of an infected animal or, in rare instances, by an inhalation of airborne viral particles in bat-infested caves or by laboratory workers. o   AIDS  and HIV  encephalitis (also known as AIDS dementia) is caused by the human immunodeficiency virus (HIV). The HIV could directly infect the    List of diseases associated with infectious pathogens    In the list of diseases associated with infectious pathogens given below, bear in mind that there is no definitive proof that the associated pathogens do play a causal role in the disease, just a possibility that they might. Further research is required to determine whether or not these pathogens participate causally in their associated diseases. Note that this list covers some of the most common human diseases associated with infectious pathogens, but it is not intended to be a comprehensive list. Alzheimer's disease   Alzheimer's disease is associated with the  bacteria Chlamydia pneumoniae [15]  and Helicobacter pylori, [16]  and with the protozoan  parasite Toxoplasma gondii. [17]  Herpes simplex virus 1 is associated with Alzheimer's disease in individuals who possess the APOE-4 form of the APOE gene (APOE-4 enables the herpes virus to enter the brain). [18]   Amyotrophic lateral sclerosis   Amyotrophic lateral sclerosis, the most  common of five forms of  motor neuron disease,  is associated with echovirus (an enterovirus)  infection of the central nervous system, [19]  and with retrovirus [20]  activity (it is not known whether this retrovirus activity arises from a human endogenous retrovirus, or from an exogenous retrovirus). Anorexia nervosa   Infection with Borrelia species bacteria is associated with anorexia nervosa. In rare cases, anorexia nervosa may arise after infection with Streptococcus [22]  species bacteria. Anorexia (which is distinct from anorexia nervosa) is associated with the protozoan parasite Dientamoeba fragilis. [23]   Anxiety disorder Anxiety is associated with cytomegalovirus, and the bacterium Helicobacter pylori. [25]   Asthma   Asthma is associated with rhinovirus, human respiratory syncytial virus, [26]  and the bacterium Chlamydia pneumoniae. [27]  Chlamydia  pneumoniae is particularly associated with adult-onset asthma. [28]   Atherosclerosis   Atherosclerosis is associated with the  bacterium Chlamydia pneumoniae. [29][30]   Attention deficit hyperactivity disorder   Attention deficit hyperactivity disorder (ADHD) and learning disorders are associated with the bacteria Borrelia burgdorferi and Streptococcus, and with HIV and enterovirus 71. Febrile seizures due to human herpesvirus 6  or  influenza A are a risk factor for ADHD. Viral infections during pregnancy, at birth, and in early childhood are risk factors for ADHD. [31]   Autism Autism is associated with prenatal maternal infection with rubella virus or cytomegalovirus. [32][33]  Clostridia  bacteria species are associated with autism (these  bacteria are present in greater numbers in the guts of autistic children). [34]    Autoimmune diseases   Autoimmune diseases are strongly associated with enteroviruses such as Coxsackie B virus. [35]  Autoimmune diseases are also associated with Epstein-Barr virus, [36]  cytomegalovirus, [37]   parvovirus B19, [38]  and HIV, [39]  and the bacterium Mycobacterium tuberculosis. [40]  Autoimmune thyroid disease is associated with Epstein-Barr virus [41]  and Helicobacter pylori. [42]   Bipolar disorder Bipolar disorder is associated with  bornavirus, [43]  and with Borrelia [21]  species  bacteria. Cancer   Some estimates currently attribute 15% to 20% of all cancers to infectious pathogen causes. [44][45]  In future, this percentage may be revised upwards if the pathogens currently associated with cancers (such as those listed  below) are proven to actually cause those cancers. (Note: for the sake of completeness, some infectious pathogens known to cause cancers are included in the list, in addition to the infectious pathogens associated with cancers.) Adrenal tumor  is associated with BK virus  and simian virus 40. [46]   Anal cancer  is associated with human  papillomaviruses. [47]   Bladder cancer  can be caused by Schistosoma  helminths.   [48]   Brain tumor . Glioblastoma multiforme is associated with cytomegalovirus, [49]  BK virus,  JC virus, and simian virus 40. [50]   Breast cancer  is associated with mouse mammary tumor virus, Epstein-Barr virus, and human papillomaviruses. [51]   Carcinoid tumors  are associated with enterovirus infections. [52]   Cervical cancer  can be caused by human  papillomaviruses. [53]   Colorectal cancer  is associated with the  bacteria Helicobacter pylori, Streptococcus  bovis and Fusobacterium nucleatum, [54]  with human papillomaviruses, [55]  and with the helminth Schistosoma japonicum. [56]  JC virus   may be a risk factor for colorectal cancer . Gallbladder cancer  is associated with the  bacterium Salmonella typhi. [58]   Hodgkin's lymphoma  is associated with Epstein-Barr virus,   [59]  hepatitis C virus, [60]  and HIV. [61]   Kaposi's Sarcoma  can be caused by Kaposi's sarcoma herpesvirus and HIV.  Liver cancer . Hepatocellular carcinoma can be caused by hepatitis B virus, hepatitis C virus, [62]  and by the helminth Schistosoma japonicum. [63]   Lung cancer  is associated with the bacterium Chlamydia pneumoniae, [64]  with human  papillomaviruses, and with Merkel cell  polyomavirus. [65]   Leukemia . Adult T-cell leukemia can be caused by human T-cell leukemia virus-1.  Mesothelioma  is associated with simian virus 40,   [66]  especially in conjunction with asbestos exposure. Nasopharyngeal carcinoma  can be caused by Epstein-Barr virus.  Non-Hodgkin lymphoma  is associated with HIV and simian virus 40.   [67]   Oropharyngeal cancer  can be caused by human papillomaviruses.  Ovarian cancer  is associated with mumps virus.  Pancreatic cancer  is associated with hepatitis B virus and the bacterium Helicobacter pylori.  Prostate cancer  is associated with xenotropic murine leukemia virus-related virus and BK virus.  Skin neoplasm  is associated with human  papillomaviruses.  Squamous cell carcinoma  is associated with human papillomaviruses.  Stomach cancer  is associated with the  bacterium Helicobacter pylori.  Thyroid cancer  is associated with simian virus 40.  Chronic fatigue syndrome   Chronic fatigue syndrome (also known as myalgic encephalomyelitis) is associated with enteroviruses (such as Coxsackie B virus), [68][69]  human herpesvirus 6 variant A, [70]  human herpesvirus 7, [71]  and  parvovirus B19. [72][73]  The  bacteria Coxiella burnetii [74]  and Chlamydia
