TREATMENT

Associated diarrhea caused by Escherichia laktozonehatyvnymy ,
salmonella , staphylococcus, Aspergillus can cause pneumonia, granular
degeneration of hepatocytes of the liver, glomerulonephritis, nefronefryt ,
desquamation and destruction of surface epithelium of the villi of the intestinal
mucosa . In the application of probiotics for treatment , the number
laktozonehatyvnyh E. coli , salmonella , fungi of the genus Candida and
staphylococci is reduced by 1-2 orders of stabilizing indicators of natural
resistance and promotes healing the sick calves .
Associated diarrhea patoloanatomichni changes probiotics..
The main cause of dysbiosis in calves , most researchers consider
activation of pathogenic microorganisms.
Pathogenic microflora is crucial in the etiopathogenesis of mass respiratory
and gastrointestinal diseases of young cattle . When developing means of
therapy should be remembered that the members of this microflora acquired
resistance to most antimicrobial agents , which greatly complicates treatment [1 ,
5].
In the event of dysbiosis in the gut microflora useful disappears , an
increase in the number of opportunistic pathogens and normal microflora loses
its ability to act as the primary nonspecific barrier activated immune processes .
In the treatment of probiotics status confirmed clinical cure fastest stabilization
indicators of natural resistance [ 1].
The purpose of the study – define the term probiotic use drugs in the
course of the associated diarrhea in calves.
Materials and methods. Studies were conducted on Simmental calves in
Pereyalov -Khmelnitsky region . Pieces of internal organs: lungs , liver , kidneys ,
spleen , intestines examined histologically and by prints.
Results and discussion. During postmortem autopsies calves 3-5 days of
age who suffered from clinical signs of diarrhea, lung revealed pneumonic
changes character. Affected areas of the lungs with a dense texture and grayishred. Pneumonia characterized by proliferation of histiocytic cellular elements in
mezhalveolyarnyh walls. The above resulted in thickening of the alveolar walls,
with simultaneous respiratory epithelial cell desquamation alveoli and bronchi.
Along with the proliferative response of this type of pneumonia in
mezhalveolyarnyh partitions detected as a circulatory disturbance. Some lung
slices observed areas mikroareaktyvnoho character.. Intermediate fabric
dramatically expanded limfosudyny zatrombovani . In some parts of the liver
revealed granular degeneration of the cytoplasm of hepatocytes. In the
connective tissue stroma of the liver - flushing mizhdolkovyh vessels.
In the kidneys abruptly found between renal tubules congestion ,
hemorrhage and congestion of the capillaries and mikronekrozy observed in the
cerebral layer. The epithelium of the renal tubules of cortical areas in some
places in the state of granular dystrophy , and there are few areas
mikroareaktyvnoho necrosis. In rare renal glomeruli - seroznodeskvamatyvnyy
extracapillary glomerulonephritis. Renal glomeruli compressed between a ball
and capsules Shymlanskaya big white space. Therefore determine nefronefryt .
In the spleen limfofolikuly in a state hyperplasia , available brown pigment
of blood.
In the abomasum - swelling of the submucosal layer, focal atrophy of the
papillae mucosa, desquamation of surface epithelium of the villi of the mucosa.
Areaktyvnyy necrosis in the deeper layers of muscle membrane, muscle and
submucosal membrane in some layers of the mucosa.
The 12-arsonist, hungry, iliac, blind, colon revealed destruction of the villi
of the mucous membrane and epithelial desquamation villous mucosa. In
addition, the small intestine observe hyperplasia limfofolikuliv at the base of the
mucosa. The 12-duodenum sometimes areaktyvnyy necrosis of muscle
membrane, submucosa and mucosa. In some places the hungry gut villous
atrophy, areaktyvnyy necrosis in muscle and mucous membranes. In the ileum areaktyvnyy necrosis of muscle and mucosa. So in addition to significant
changes in the digestive canal, affects the respiratory system, liver and kidneys.

Associated diarrhea caused by lactosonegative Escherichia, Salmonella,
Staphylococci, Aspergillus which can cause pneumonia, granular degeneration of
the liver hepatocytes, glomerulonephritis, nephronephrytis, desquamation and
destruction of surface epithelium of the villi of the intestinal mucosa. Using
probiotics for treatment of this diseases, amount of lactosonegative Escherichia,
Salmonella, fungi of Candida family and Staphylococci reduced in 1-2 orders that
stabilizes the level of natural and promotes recovery of sick calves.
