The milestone in polio eradication program is to protect effectively children aged 0-5 years against the three serotypes of poliovirus. It became necessary to measure the level of neutralizing antibodies to the three poliovirus types in an endemic State in Nigeria. Neutralizing antibodies to the poliovirus types among children aged 0-5 years was estimated using micro neutralization assay. Of 129 children, 99 (76.8%), 95 (73.6%), and 95 (73.6%) had neutralizing antibodies with the geometric mean titer of 42.7, 31.3, and 33.2 for the poliovirus type 1, 2, and 3, respectively. Fifty-three percent of the children were protected against the three types of poliovirus. Combination of poliovirus types 1 and 2, 1 and 3, and 2 and 3 were neutralized by 62.8, 58.9, and 61.2% of the children studied, respectively. Only poliovirus type 1 induced antibody titres ≥1:1,024. The number of children with neutralizing antibodies after receiving three doses was significantly higher than those who received one or two doses of oral polio vaccine (P ≤ 0.05). However, those who received more than three doses of oral polio vaccine showed no significant difference in their antibody response. The existence of immunity gap poses a risk of re-emergence of the paralytic poliovirus. The existence of unimmunized and unprotected children along with high birth rate could impede the success of polio vaccination in Nigeria. Elimination of non-compliance to polio vaccine, promotion of health education and documented evidence of vaccination of each child with the parents may facilitate the success of polio eradication program in Nigeria.

Listeria monocytogenes is a food borne pathogen which usually infects individuals with impaired cellular immunity and the healthy. Gastrointestinal tract (GIT) of the humans has lots of defensive mechanisms placed to prevent pathogens from establishing themselves and cause infectious diseases. Survival depends on the pathogen’s ability to overcome such preventive mechanism of the host. Listeria monocytogenes exhibits array of mechanisms that ensure its survival against these stressor. These stressors include gastric acid, bile salt, low oxygen tension, antimicrobial peptides e.t.c. Acid tolerance system (ATR), glutamate decarboxylase system (GAD), BilE system, MVs, oxygen sensors are used by Listeria monocytogenes to enhance its chances of survival within host. Our interest here is to look at such adaptive mesures with respect to the stressors encountered.

Background: Chlamydia trachomatis infection is an established cause of pelvic inflammatory disease (PID), ectopic pregnancy, chronic pelvic pain and infertility among women. It is the most common bacterial sexually transmitted disease in the world. The infection is largely asymptomatic. Aim: The study was carried out to determine the Clinical background as well as detect the Chlamydia trachomatis antigen among infertile women attending University of Maiduguri Teaching Hospital (UMTH). Methods: A survey on the Clinical background and antigens to Chlamydia trachomatis was carried out among infertile and post natal women attending fertility Clinic UMTH. A total of 65 endocervical swab samples were collected from the aforementioned group of subjects within the age of 18-47 years, out of which 45 were collected from infertile women while the remaining 20 were obtained from post-natal women to serve as control subjects. The samples were analysed by using Chlamydia Rapid Test device swab/urine (Abon Biopharm(Hangzhou), Co., Ltd) that work on the principle of immunochromatographic technique. Results: Highest number of infertility was observed on women within the age of 30-35 years (33.3%). The result shows that those that attained tertiary educational level have the highest number of infertility (60%). The study demonstrated highest number of infertility among female civil servants (53.3%) followed by full-time house wife (33.3%). More infertility was observed among women who are not engaged in the use of contraceptive measures (95.6%). The overall result from this study shows no prevalence (0.0%) of C. trachomatis genital infection among infertile women in UMTH. Conclusion: Further research using more sensitive and specific procedures for the detection of C. trachomatis from clinical specimens such as nucleic acid amplification tests and cell culture are recommended among infertile women in Borno State, Nigeria.

Aim: We determine the prevalence of TB and MDRTB within the study population. Methodology: The sampling consists of 192 (54.4%) males and 161 (45.6%) females.  Ziehel Neelsen staining method was used for the detection of Acid Fast Bacilli (AFB) in the sputum samples collected. Rifampicin resistant (MDRTB) isolates were detected by GeneXpert and the conventional PCR technique. Results: In this study, 6 (9.5%) out of the 63 positive samples were rifampicin resistant Mycobacterium tuberculosis in which 4(6.3%) were found among females and 2 (3.2%) were found among males. Infection with Mycobacterium tuberculosis was not dependent on gender statistically in this study P>0.05. Secondary institution among the health care centers had highest cases of tuberculosis18 (33.3%) while tertiary institute had higher rifampicin resistant tuberculosis 5(2.5%). Statistically there was significant relationship between occurrence of tuberculosis and health care centers p<0.05. Conclusion: There is need to establish more reference laboratories within the country in order to address the rising cases of tuberculosis. There is also need for urgent attention of the government and other developmental partners to address the rising cases of MTB and MDRTB which is outside the expected ratio of 3:1 (male : female) stipulated by the World Health Organisation (WHO) and to conduct a national tuberculosis drug resistance survey so as to determine the actual burden of MDRTB in Nigeria.
