The aim of this review was to evaluate the new progress regarding the use of Lactobacillus species as live delivery vectors, prevention, and treatment of pathogenic and metabolic diseases. Lactobacillus strains of probiotics have been extensively studied and have confirmed that they can absolutely improve performance as live delivery vectors, a treatment option of various diseases such as: Hemorrhagic cecal coccidiosis in young poultry, hypertension, avian flu, obesity, diabetes, Derzsy’s disease or parvovirus infection, human immunodeficiency virus infections, irritable bowel syndrome, gastrointestinal disorders, Fungal infections, vaginal eubiosis, fish and shellfish species diseases. We give you an idea about that Lactobacillus species have been proficient in preventing and treating both disorders in animal models and some are used for clinical trials. We present the most current studies on the use of Lactobacillus strains that had an impact on an effective immune response to a specific antigen because a variety of antigens have been expressed. Therefore Lactobacillus strains can be considered as good candidates because of its potential for diseases treatment and vaccine development as heterologous protein secretion to date.展开更多

In general estimated prevalence for porcine cysticercosis by Ag-ELISA was 29.7% (95% CI [4.8 - 58.2]), by EITB was 24.7% (95% CI [9.2 - 38.2]), by Tongue examination was 9.4% (95% CI [0.2 - 13.2]), and by postmortem examination was 15% (95% CI [0.2 - 27.4]). Average seroprevalence of human cysticercosis by circulating antibody detection (Ab-ELISA) was ranged from 1.3% to 45.3%. Average seroprevalence of human cysticercosis by circulating T. solium antigen detection (Ag-ELISA) was ranged from 4.6% to 11.9%. Average seroprevalence of human cysticercosis by EITB was ranged from 6.9% to 16.7%. Average prevalence of human cysticercosis by CT scan was ranged from 23.2% to 54.6%. A fundamental factor in the occurrence of infections in most of the article was lack of health education to the community on T. solium, cysticercosis and taeniasis complex as the key towards control and eradication. The major causal factors of the disease occurrence were free roaming pigs and poor sanitary conditions.展开更多

The current study patterns of TLR2, TLR3 and TLR9 expressing antigen presenting cells (APCs) in blood of mice after colonization with L. plantarum NC8 strain were assessed. The power of L. plantarum on serum innate cytokine and TLR responses stimulated by recombinant NC8-pSIP409-pgsA-VP6-DCpep, NC8-pSIP409-pgsA-VP7-DCpep and NC8-pSIP409-pgsA were also assessed. We confirmed that L. plantarum NC8 stimulated powerful TLR2 expressing APC responses in blood Recombinant strain stimulated a TLR3 response in spleen, and TLR9 responses were stimulated in blood or in spleen. Recombinant NC8-pSIP409-pgsA-VP6-DCpep, NC8-pSIP409-pgsA-VP7-DCpep on TLR2 and TLR9 expressing APC responses has a preservative outcome, reliable with the DCpep adjuvant outcome. In serum the recombinant NC8-pSIP409-pgsA-VP6-DCpep, NC8-pSIP409-pgsA-VP7-DCpep has increased the IL-4 and IFN-γ responses, except that on the TLR3 and TLR9 expressing CD14 APC responses it had an oppressive consequence in spleen and the IFN-α response in serum-stimulated by PRV. Our results give details that following PRV infection after immunization with NC8-pSIP409-pgsA-VP6-DCpep, NC8-pSIP409-pgsA-VP7-DCpep, the systemic TLR2, TLR3, and TLR9 expressing cDC and macrophage/monocyte responses.展开更多
