The genetic characterization of Clarias gariepinus was conducted in this study. Thirty (30) C. gariepinus specimens were collected, fifteen (15) each from the wild and farms in northeastern Nigeria for their genetic relatedness and diversity using the RAPD markers. DNA extraction from the blood sample was performed using the Gene Jet Genomic DNA Purification Kit. Five primers were used in employing PCR and amplified 402 RAPD bands from the four strains of Clarias gariepinus. Three hundred and six (76.12%) bands were polymorphic while 86 (21.39%) were monomorphic. The percentage of polymorphism obtained from farmed and wild populations ranged from 58 (47.3%) to 69 (75.9%), respectively. The polymorphic bands per loci within the populations ranged from 67.9% to 82.0%. The mean numbers of inbreeding coefficient (FIS) were 0.083 and 0.053 in the farmed and wild populations. Gene diversity values within farmed and wild populations (Ht) were 0.4522 and 0.4018. The mean genetic differentiation (FST) ranged between (0.203) in the farmed and 0.129 in the wild populations. The analysis of molecular variance revealed that there was 96% of genetic variance within the population and 4% among the population. The genetic identity and distance of four populations were 0.9490 and 0.1038, respectively. The phylogenetic measure has shown that the four strains were divided into two clusters at approximately 0.089 similarity levels. The result indicated a significant level of genetic variation and minimal dendrogram separation in Clarias gariepinus in northeastern Nigeria. Conclusively, this information will be a useful tool for the genetic and breeding program of Clarias gariepinus.

Tick-borne encephalitis virus (TBEV) was isolated for the first time in Sweden in 1958 (from ticks and from 1 tick-borne encephalitis [TBE] patient).1 In 2003, Haglund and colleagues reported the isolation and antigenic and genetic characterization of 14 TBEV strains from Swedish patients (samples collected 1991–1994).2 The first serum sample, from which TBEV was isolated, was obtained 2–10 days after onset of disease and found to be negative for anti-TBEV immunoglobulin M (IgM) by enzyme-linked immunosorbent assay (ELISA), whereas TBEV-specific IgM (and TBEV-specific immunoglobulin G/cerebrospinal fluid [IgG/CSF] activity) was demonstrated in later serum samples taken during the second phase of the disease.

Introduction: Syphilis is one of several diseases that can be transmitted during pregnancy and childbirth, which can lead to complications during pregnancy and in the newborn. This is especially so when the pregnant woman is not diagnosed or treated properly and in a timely manner. Methodology: Data from 262 pregnant women prospectively included, aged 18-41years, attended at the Ponta Gêa Health Centre for antenatal clinics has been analyzed from January to September of 2016. In the prospective study, a rapid treponemal and a non-treponemal test were performed. A structured questionnaire was used to collect socio demographic and clinical variables, which was developed from the literature review. Results: The prevalence of active syphilis was 11.8%; the majority of reactive pregnant women were aged 18-25years (55.4%), (61.3%) of pregnant women were treated with doses below those recommended; only a small number of the partners were treated successfully. The highest seroprevalence of syphilis was found in housewives (77%), in those who attended primary education (71.6%) in those who had a monthly income of 1000- 3000 MZN (70.3%), in those with two or more pregnancies (55.7%) and living with someone has husband and wife (63.5%). The syphilis/HIV co-infection rate was high. Conclusion: According to the results obtained in this study, urgent measures are needed to assess the problems encountered and to improve the screening approach, treatment and monitoring of syphilis during pregnancy in order to prevent the cases of congenital syphilis.
