  Bacilli - Wikipedia, the free encyclopedia
The term bacilli (singular bacillus) is used to refer to any rod-shaped bacteria.
As a formal taxon, the Bacilli (capitalized) are a class of Firmicutes, including Bacillus and various other Gram-positive bacteria, such as Listeria.
The Bacilli are distinguished from the Clostridia by aerobic respiration.

 THE MERCK MANUAL, Sec. 6, Ch. 73, Pneumonia
Gram-negative bacilli colonize the upper airways in patients who have serious underlying diseases with a frequency directly correlated with disease severity.
Gram-negative bacilli should be suspected in a patient with pneumonia who is in one of the risk categories noted above, especially with neutropenia or nosocomial pneumonia.
Gram stain of sputum usually shows numerous gram-negative bacilli; however, distinguishing the various species and genera on the basis of morphologic characteristics is impossible.

 Typhoid Bacilli Carriers
Typhoid bacilli were present in the liver, in the wall of the gall bladder and inside a number of calculi.
When the bacilli were in the stools of typhoid carriers, Lentz found that he could not get rid of them by any treatment.
This suggests that the chief development of the bacilli is in the intestines, although the source of the infection is probably the gall bladder.

bacilli; thus, they are likely to contain a small number of bacilli resistant to each of the antituberculosis drugs but unlikely to contain bacilli resistant to two drugs simultaneously (3).
When medications are not taken as prescribed, the infecting bacilli may be exposed to a single drug for long periods of time, which allows drug-resistant organisms to emerge (Figure 3).

 Typhoid Bacilli Carriers
A bacteriologie examination of the urine and feces of this man was made and typhoid bacilli found in the urine in considerable number.
She is perhaps justified in this conclusion, because the gall bladder is not the only source of the typhoid bacilli that appear in the feces.
Sometimes the feces of these carriers contain such large numbers of typhoid bacilli as almost to displace the colon bacillus; it seems that the typhoid bacillus may take up a natural habitat somewhere in the intestinal tract independent of the gall bladder.

 THE MERCK MANUAL, Sec. 13, Ch. 157, Bacterial Diseases
Typhoid bacilli are shed in the feces of asymptomatic carriers or in the stool or urine of those with active disease.
Typhoid bacilli are usually isolated from cultures of blood or bone marrow only during the first 2 wk of illness, while stool cultures are usually positive during the 3rd to 5th wk.
Typhoid bacilli may be isolated for as long as 3 to 6 mo after the acute illness in persons who do not become carriers; thereafter, three negative stool cultures at weekly intervals must be acquired to exclude a carrier state.

Tubercle bacilli are numerous and are demonstrated in tissue and intravascular spaces.
Typical tubercles with acid-fast bacilli are found in the lower dermis and walls of the ulcer or abscess.
Tubercle bacilli are difficult to demonstrate, but patients usually have an internal focus of TB and are tuberculin sensitive, and skin lesions resolve after anti-TB therapy.

Anaerobic Gram-negative bacilli are common elements of the mucous membrane flora throughout the body; they often act as secondary pathogens.
Gram-negative anaerobic bacilli may cause infections anywhere in the body; the most common types are oral and dental, pleuropulmonary, intra-abdominal, female genital tract and skin, soft tissue and bone infections (Table 20-1).
Glucuronidase produced by anaerobic Gram-negative bacilli may be of special significance in deconjugating compounds that had previously been detoxified in the liver by combination with glucuronide.

 "Tuberculosis in animals: Mycobacterium bacilli that cause devastating zoonotic diseases in many animals"   (Site not responding. Last check: 2007-11-07)
Tuberculosis is an infectious, granulomatous disease caused by acid-fast bacilli of the genus Mycobacterium.
Once the bacilli get into a susceptible organism, a number of events occur which cause the characteristic disease.  It generally starts in the areas where the exposure occurs.  The lungs are often attacked, but other parts of the body can be affected.
This is difficult where pastured animals are infected by exposure to diseased wild animals.  Hygienic measures to reduce contamination of facilities is also useful.  The use of drugs is discouraged due to exposure of humans to animals being treated, possible development of drug resistant strains, and the expense to producers.

 (Page 15 of 16) Module 3: Diagnosis of Tuberculosis Infection and Disease
It is very important for health care workers to use precautions to control the spread of tubercle bacilli during these procedures and any other procedures that may cause persons who have pulmonary TB disease to cough.
Tubercle bacilli that are killed by a particular drug are said to be susceptible to that drug, whereas those that can grow even in the presence of a particular drug are said to be resistant to that drug.
The drug susceptibility pattern of a strain of tubercle bacilli is the list of drugs to which the strain is susceptible and to which it is resistant.

Clostridia are strictly anaerobic to aerotolerant sporeforming bacilli found in soil as well as in normal intestinal flora of man and animals.
The clostridia that cause gas gangrene are anaerobic, spore-forming bacilli, but some species may not readily sporulate, e.g., C perfringens.
By the time the typical lesions of gas gangrene are evident, the disease usually is firmly established and the physician must treat the patient on a clinical basis without waiting for laboratory confirmation.

The infectiousness of a TB patient is directly related to the number of tubercle bacilli that he or she expels into the air.
Because there are many tubercle bacilli in a cavity, patients who have a cavity in the lung may be expelling tubercle bacilli if they are coughing.
The presence of acid-fast bacilli on a sputum smear indicates that the patient may be expelling tubercle bacilli.

 Pharmaceutical compositions for promoting the growth of gram-positive bacilli and increasing the acidity in the vagina ...
When the Gram-positive bacilli are reduced or disappear in vagina, vaginal pH value rises and disturbance of vaginal bacterial flora results from abnormal increases of Gram-negative bacilli, Gram-positive cocci and Gram-negative cocci, which can cause harm to the human body and lead to a range of diseases.
BV is characterized by the reduction or even disappearance of Lactobacillus and other Gram-positive bacilli in the vagina, accompanied by decreased acidity (pH value>4.6) in the vagina, and abnormal increases of such bacteria as Gram-negative bacilli including Gardnerella, Bacteroides and motile-curved bacilli; Gram-negative cocci such as Veillonella; and Gram-positive cocci such as Streptococcus.
As shown in Table 3, although there was few Gram positive bacilli in the vaginal secretion specimen, the Gram positive bacilli grew in the compositions containing different sugars of this invention after the compositions were inoculated with specimen suspension and cultivated for 24 hours or 48 hours.

 Comments on the armadillo-leprosy controversy
Fractionation of bacilli from lepromas proved difficult and reticuloendothelial organs (they refer to livers and spleens) were found to yield bacilli of greater purity, even though the average bacillary content of those tissues is lower.
Rees also reported that the bacilli could be isolated in a much higher degree of purity from livers and spleens than from lepromas which were supplied to him previously.
Thus the purity of armadillo-derived bacilli as well as the quantity was reduced by untimely closing of her program.

 [Frontiers in Bioscience 3, c27-33, May 1, 1998]
For this reason, Lurie used human-type tubercle bacilli (strain H37Rv) in which 50 to 600 bacillary units must be inhaled to produce one grossly visible primary lesion, depending on the native resistance of the rabbit (1-4,8).
Virulent bovine-type tubercle bacilli are apparently more infectious for rabbits than for humans: One inhaled unit of 1 to 3 fully virulent bovine-type bacilli in the alveolar spaces is sufficient to establish the disease in rabbits (1,6).
Such bacilli in rabbits produce a cavitary disease with spread via the bronchial tree, which is quite similar to that found in immunocompetent human beings.
