  • Review on Plants Therapeutic Effects against Gastrointestinal Microbes

    Plants play a vital role in many health care systems, be it rural or an urban community. Plants became familiar as medicine due to the ancient ideologies and believes. Several plants parts of plants served as medicines to so many ailments including gastrointestinal ailments, due to the fact that their active ingredients are powerful against the microbes. Most of the microbes identified were gram negative bacteria as well as some gram positive. Some of the principal antibacterial components of plants were recommended being polar compounds. While most of the acknowledged components with antimicrobial activity extracted from plants were aromatic or saturated organic compounds which were more soluble in polar solvents such as water and methanol. As such plants materials in one way or the other are very active when dealing with microbes due to their active ingredients.

  • Oedematous skin disease (OSD) transmission among buffaloes

    During buffaloe OSD spread in a village affiliating to Assiut Governorate-Egypt, 44 buffaloe cows hosted and owned sporadically were subjected to the study. From 43 buffaloe cows (had closed lesions either edematous or nodular) and a buffaloe cow (had open ulcerative lesion), Corynebacterium pseudotuberculosis equi (C. ps. equi) as 72% and Corynebacterium pseudotuberculosis ovis (C. ps. ovis) as 28% were isolated and identified. Blood sucking insects hosted on the infected buffaloe cows (22) louse fly (Hippobosca equine) and 20 Haematopinus eurysternus lice were included during the study where both C. ps. equi and C. ps. ovis were isolated from Hippobosca equina ( H equina) but failed to isolate any biovar of C. ps. from Haematopinus eurysternus lice (H. eur.). Moreover, C. ps. equi was isolated from two H equina pupae – lab deposited – as well as a H equina second generation fly concluding that there is endosymbiosis nature of C. ps. limited only to H. equina fly which can transmit C.ps. vertically.

  • The effect of Transfer Factor as Immunotherapy comparing with the effect of BCG in Mice challenged with Mycobacterium tuberculosis

    Background: Transfer Factor (TF) is an immune modulator which stimulates the cellular arm of the immune system (killer lymphocytes), activates immune cytokine synthesis and regulates immune function (Lawrence, 1955).TF is very effective in those diseases in which CMI plays a relevant role in protection and control of the disease, such as intracellular bacterial diseases (tuberculosis). ( Estrada Parra, et al1955). TF are low molecular weight products from immune cells that are able to transmit the ability to express delayed-type hypersensitivity (DTH) and cell mediated immunity (CMI) from sensitized donors to non immune recipients (Kirkpatrick, 2000). Objectives: The aim of this experimental study is to determine the protective efficacy of transfer factor (TF) as immunotherapy for mice in comparison to BCG. Materials and methods: A total number of 102 mice were examined for their immunopotency and protective efficacy of Transfer factor (TF) comparing to the protective efficacy of BCG single and second repeated dose against challenge dose of M. tuberculosis (107 CFU) . A number of 20 mice were immunize with the attenuated strain of M. bovis, Bacillus Calmette-Guérin (BCG). After 21 days of BCG spleens of 10 tuberculous mice were removed aseptically for the preparation of TF. To evaluate the effect of TF 3 groups of inbred BALB/c male mice were injected with TF and challenged with virulent M. tuberculosis, followed by another 3 groups of inbred BALB/c male mice which were immunized with BCG single and second repeated dose. All mice with BCG and TF were tested for tuberculin skin test (TST) so as to determine susceptibility and resistance against tuberculosis, susceptible groups of mice were challenged with virulent M. tuberculosis. Followed by study of humoral response by immunization of a group of mice with immune serum and challenged with M. tuberculosis H37Rv strain. Followed by an experiment of…

  • Breast Cancer and Herbal Treatment

    All around the world about1.7 millions of females are resulted with breast cancer and arround 522,000 deaths. Which is more common in developed countries than the developing ones. Breast cancer mostly occurs in cells from the lining of milk ducts and the lobules that supply the ducts with milk. Symptoms of Breast cancer includes a lump in the breast, dimpling of skin, change in shape of breast, fluids coming from nipple. Risk factor for development of breast cancer includes age, sex, obesity, lack of physical exercise, alcohol consumption, hormone replacement therapy during menopause, exposure to ionizing radiation, early age at first menstruation, and family history. Breast cancer is the most serious health problem in developed countries, proper diet, exercise and healthy life style can reduces the risk of breast cancer. Surgery and chemotherapy are the treatment for breast cancer, as chemotherapy has many side effects 50% weakness occurs due to cancer and 50% weakness occurs due to chemotherapy, hence herbal drugs or herbal treatment is the best option for breast cancer. Number of herbal drugs are effective in breast cancer In this study detailed study of the herbal drug used in breast cancer is discussed in detail.

  • Elevated Serum Procalcitonin an Adjunct for Early detection of Infant Tuberculosis in Paediatric HIV/AIDS

    In countries with a high tuberculosis (TB) burden, Mycobacterium tuberculosis is a frequent cause of acquired pneumonia (AP) amongst people living with HIV/AIDS and the differential and early diagnosis of TB from common bacterial pneumonia is difficult. The varying clinical and radiographic presentation of Acquired Pneumonia and Tuberculosis according to patient age and comorbidity and the low sensitivity of acid-fast bacillus microscopy make it even more difficult to distinguish TB from common bacterial pneumonia. Therefore, an adjunct diagnostic method that can determine early pulmonary tuberculosis in infants living with HIV/AIDS in order to differentiate it from other bacterial pathogens causing acquired pneumonia. Although a confirmatory microscopy test for Tuberculosis detection was carried out which would have a clinical role in terms of isolating patients with TB and administering appropriate anti-TB medication or antibiotic treatment at an early stage. The use of serum procalcitonin (PCT) for early detection of pulmonary tuberculosis (TB) from infants with paediatric HIV/AIDS in Adamawa state, Nigeria a country with an intermediate TB burden and one with the highest number of people living with HIV/IADS in West-Africa. A prospective study, enrolling 50 infants with paediatric HIV/AIDs with suspected Pulmonary Tuberculosis in a community-based referral hospital. A clinical assessment was performed before treatment, serum and PCT were measured. The test results were compared to the final diagnoses 50 patients, 35 had Pulmonary Tuberculosis and 15 had bacterial associated pneumonia TB. The median PCT level was 0.564 ng/mL (range, 0.01 to 27.75) with bacterial acquired pneumonia and 0.044 ng/mL (range, 0.01 to 0.87) with pulmonary TB (p

  • Heamatologic Indices and Anti-Spermatogenic Effects of Dietary Supplemented Carica papaya seeds on Wister Rats

    The continuous usage of indegienious plants as an intervention tool for diseases that affect both humans and animals is as old as orthodox medicine in its self in this study we evaluated the overall effect of carica papaya seeds extract on wister rats to determine its heamatoligic stimulatory effect and the anti-spermatic effect. A total of eighty rats where orally administered the various doses of the extract over a period of time and the heamatoligic and spermatologic parameters where analyzed. From the results obtained there was a slight stimulatory effects as the total white blood cell increased according to the varying doses of 100mg and 200mg respectively (6.56±0.38 and 6.96±0.10) with mean packed cell volume of 38.0±0.84 and 37.4±1.03 also noticeable is the slight rise in the Lymphocytes from the control group to the varying doses of exposure 70±2.06 and 68.6±1.12, the total Sperm cell count across the varying doses where 11.6×106 +0.5cells/mm3 and 11.3×106 +0.5cells/mm3 respectively. The above showed a a little marked increase the heamatologic parameters there was a slight increase in the lymphocyte although there was a marked decrease of sperm cell count from the control down the doses of exposure.

  • Observed variations of Plasma Procalcitonin Amonsgt Sexually Active Males With Suspected Bacterial-Urogenital Infection In Yola Metropolis

    Background: Male urogenital infection in Nigeria has increased due to alarming rise of unprotected sex amongst the sexually active males in Nigeria. Most of these case leads to a limiting advanced disease state such as kidney infections, bacteropsermia/infertility and reinal failure. AIM: To study the elevated serum Procalcitonin levels on patients with bacterial urogenital infections as an adjunct of bacterial-fungi-viral urogenital infections for diagnosis/prognosis and antimicrobial monitoring. PATIENTS and METHODS: The study group cut across adults from the ages of 20 years and above, 40 males who were suspected to have urogenital infection and 40 who were confirmed cases of urogenital infections those with suspected urogenital infections and those with confirmed urogenital infections. Using standard microbiological techniques urine and urethral swabs were taking and proper cultural techniques were carried out to isolate the bacterial/Fungi origin of infection, blood samples were collected from patients with suspected and confirmed urogenital infections for further analysis of the Procalcitonin ratio. RESULT: a total of 40 suspected males with signs and symptoms of urogenital infections where included in this study, a microbiological analysis was carried out on MSU(midstream urine clean catch) and urethral swab, and seminal fluid analysis, 40% yielded growth of gram Staphylococcus aureus and CoNs, 22.5% yielded growths of Escherichia coli, Proteus mirabilis, Acinectobacter spp, Klebseilla oxytoca while 15% had fungi/Parasitic origins,( Candida albicans and Trichomonas vaginalis) 22.5% showed no significant growth. The mean PCT ratio across the infectious agents were, bacterial origin ( 0.4-1.1 CI 0.34-0.62) fungi/parasitic origin (0.3-1.0 CI 0.28-0.56) Conclussion: although there was no remarkable difference between the confirmed cases of urogenital infection and suspected cases this showed the accuracy of PCT and its use. The reasonable increased levels of PCT in urogenital infections may serve as prognosis for asypmtomatic cases which often result to infertility, although most of the…

  • Bacteruria Associated Urogenital Infections Amongst Women “a Study On Assymptomatic And Symptomatic Presentation In Benin Metropolis, Nigeria”.

    Introduction: Symptomatic and Asymptomatic urinary tract infection in women is of great importance to determine the causal and treatment of bacteruria in young women which may lead to disease states. Aim: to determine the occurrence of asymptomatic bacteriuria in young women and its relationship with urinary tract infection Methods: A microbiological analysis of urine was done on 3600 young women in urban Benin metroplolis from July 2009 to July 2010, a total of 1105 microorganism were isolated from both Symptomatic and Asymptomatic young women. Results: From the 1105 isolates from the descending order of occurrences Escherichia coli, Kleibseilla spp, Enterococcus faecalis and Staphylococcus aureus with Acinobacter spp with the least occurrence. Escherichia coli was the commonest cause of Asymptomatic urinary tract infection with 31.6 % and Acinectobacter sp 9.5% with the least occurrence of Asymptomatic urinary tract infections. Conclusion: This study shows that there is a rise in asymptomatic urinary tract infection amongst young women in Benin City.

  • Detection of methicillin resistant and slime factor production of coagulase negative Staphylococcus spp. in bovine clinical mastitis by using PCR

    This study aims to investigate the slime production of Coagulase negative staphylococci (CoNS) isolates by phenotypic method on Congo Red Agar plates (CRA) and Genotypic detection of icaA, icaD and mecA genes by polymerase chain reaction (PCR). Out of 105 milk samples obtained from clinical bovine mastitis, 101samples (96.2%) were positive for bacterial growth. CoNS isolates was detected in 20 isolates with a percentage of 19.8%. Their ability to form biofilm as one of the most important virulence factors of the organisms using Congo Red Agar (CRA) method was investigated in which 13 out of 17 CoNS isolates (76.47%) were found to be slime producers. By PCR, mecA gene was found in threeout of 6 CoNS isolates (50%). Also six (100%) and three (50%) isolates were positive for icaA gene and icaD gene, respectively. In addition one isolate out of the six CoNS isolates (16.67%) was positive for the presence of icaA, icaD and mecA genes and also has the ability to form biofilm. The in vitro activities of CoNS against 11 selected antimicrobial agents referred that the highest resistance rate of CoNS observed to Lincomycin (100%), followed by Cefotaxime (94.41%), Oxacillin (58.82%), Ampicillin (47.06%) and Penicillin (41.18%), while the highest rate of sensitivity observed to Enrofloxacin and Gentamicin (100%, for each), followed by Doxycycline (94.11%).Conclusion, the findings of the present study demonstrated the ability of CoNS isolated from bovine clinical mastitis to form biofilms. This must be considered as an alarming situation, and so attention must be paid toward implementation of new ways for effective prophylaxis, control, and treatment of such infections in the dairy farms. The prudent use of antibiotics and rapid and continuous screening for resistant microorganisms should be more focused to prevent the emergence and spread methicillin resistant coagulase negative staphylococci, because these strains can cause…

  • The Accumulation Of Cadmium In Corn At Different Levels Of Soil Ph

    A pot experiment was carried out in the plastic greenhouse at the Institute of Sustainable Agrotechnology (INSAT), University Malaysia Perlis in Sungai Chuchuh, Perlis, Malaysia. During season of the cultivation of 2014 investigate the impact of soil pH and cadmium on growth of corn plant (Zea mays L.). Twenty five were arranged in factorial experiments according to the Complete Randomized Design (CRD), with three replicates. Five levels of soil pH were, pH4, pH5.2 (i.e., the original value), pH6, pH7 and pH8 and five levels of cadmium (Cd); Cd 1, Cd 2, Cd 3, Cd 4 and Cd 0 where the amounts (2, 4, 6, 8 mg. kg-1 soil and control treatment without add cadmium) are applied as CdCl2. Thus, the total numbers of pots were 75 pots. The results of this investigation revealed that; The decrease of soil pH led to significant effect to increase concentration of cadmium in root, stem, leaves and grain of corn, where the level of pH 5.2 gave highest concentrations of Cd compared with pH 8. the interactions between soil pH and cadmium led to increase of reduced the accumulation of cadmium in the corn, where it gave the interaction between pH 8 and Cd 0 lowest concentration of cadmium in root, stem, leaves and grain.
