Abstract
Brewing and consumption of traditional beer have social-economic significance in most African countries including Botswana. Traditional sorghum malt, wort, and beer samples were collected from three villages around Gaborone, Botswana. Forty-six malt samples were analyzed for fungi on three different media and developing colonies were subcultured for identification. Rhizopus, Fusarium, Mucor, and Aspergillus were the most common genera isolated. Out of the 46 malt samples, 72% contained Rhizopus stolonifer, 63% Fusarium verticillioides (syn. Fusarium moniliforme), and 37% Aspergillus flavus. Although Aspergillus flavus was isolated from malt samples, aflatoxins (B(1), B(2), G(1), and G(2)) were not detected in any of the samples analyzed. When the malt, wort, and beer samples were analyzed for fumonisin B(l) and zearalenone, fumonisin B(1) was detected in 3 malt samples, with concentrations ranging from 47 to 1316 mug/kg, while zearalenone was detected in 56%, 48% and 48% of the malt, wort and beer samples, respectively. Zearalenone concentration in samples ranged from 102 to 2213 mug/kg in malt, 26 to 285 mug/l in wort and 20 to 201 mug/l, in beer. Zearalenone carry-over from wort to beer ranged from 23 to 403%. Therefore, although aflatoxins and fumonisin B(1) do not appear to be major contaminants, zearalenone is common and could pose a potential problem in traditional beer in Botswana.

Abstract
Approximately two-third of the worlds HIV/AIDS cases are found in sub-Saharan Africa. The rate of mother-to-child-transmission (MTCT) has been found to lie between 15 and 40%. The aim of this study was to explore the social consequences affecting the experience HIV-positive women have when taking part in a prevention of mother-to-child-transmission programme (PMTCT). Few studies have investigated this earlier. A cross section of 52 participating women enrolled into a PMTCT programme were randomly selected and interviewed, using a structured questionnaire. There were three main findings. The most important consequence of participating was the difficulty associated with the breast-feeding issue. For the women who because of a wish to prevent MTCT are employing formula feeding, this causes suspicion and prejudice amongst people in the local community. Few people influence a woman's decision to take part, as they tend to keep their HIV status to themselves. More information to the general public about HIV and PMTCT programmes will enhance acceptance to HIV, and generate an environment conducive towards participation in PMTCT programmes.

Abstract
This article examines the utilization characteristics and importance of woody biomass resources in the rural-urban fringe zones of Botswana. In the literature for Africa, attention has been given to the availability and utilization of biomass in either urban or rural environments, but the rural-urban fringe has been neglected. Within southern Africa, this neglect is not justified; the rural-urban fringe, not getting the full benefits available in urban environments in Botswana, has developed problems in woody biomass availability and utilization that require close attention. In this article, socioeconomic data on the importance of woody biomass in the Batlokwa Tribal Territory, on the rural-urban fringe of Gaborone, Botswana, were collected together with ecologic data that reveal the utilization characteristics and potential for regrowth of woody biomass. The analysis of these results show that local woody biomass is very important in the daily lives of communities in the rural-urban fringe zones and that there is a high level of harvesting. However, there is no effort in planning land use in the tribal territory to either conserve this resource or provide alternatives to its utilization. The future of woody biomass resources in Botswana's rural-urban fringe is uncertain. The investigators recommend that a comprehensive policy for the development of the rural-urban fringe consider the importance of this resource. The neglect of this resource will have far-reaching implications on the livelihoods of residents as well as the environment in this zone.

Abstract
The modern environmental management literature stresses the need for community involvement to identify indicators to monitor progress towards sustainable development and environmental management goals. The purpose of this paper is to assess the impact of participatory processes on sustainability indicator identification and environmental management in three disparate case studies. The first is a process of developing partnerships between First Nations communities, environmental groups, and forestry companies to resolve conflicts over forest management in Western Canada. The second describes a situation in Botswana where local pastoral communities worked with development researchers to reduce desertification. The third case study details an on-going government led process of developing sustainability indicators in Guernsey, UK, that was designed to monitor the environmental, social, and economic impacts of changes in the economy. The comparative assessment between case studies allows us to draw three primary conclusions. (1) The identification and collection of sustainability indicators not only provide valuable databases for making management decisions, but the process of engaging people to select indicators also provides an opportunity for community empowerment that conventional development approaches have failed to provide. (2) Multi-stakeholder processes must formally feed into decision-making forums or they risk being viewed as irrelevant by policy-makers and stakeholders. (3) Since ecological boundaries rarely meet up with political jurisdictions, it is necessary to be flexible when choosing the scale at which monitoring and decision-making occurs. This requires an awareness of major environmental pathways that run through landscapes to understand how seemingly remote areas may be connected in ways that are not immediately apparent.

Abstract
OBJECTIVE To describe the response to highly active antiretroviral treatment (HAART) in a public sector pilot antiretroviral (ARV) treatment program in Botswana. METHODS The response to HAART is described in adult HIV-infected ARV-naive patients initiating treatment from April 2001 to January 2002 at Princess Marina Hospital in Gaborone, Botswana. Patients had medical and laboratory evaluations before initiating ARV treatment and were followed longitudinally. For analysis, data were collected from charts and patient management records. RESULTS One hundred fifty-three ARV-naive patients initiated HAART. Most received didanosine plus stavudine (ddI + d4T) with efavirenz or nevirapine. The mean CD4 cell count increase was 149 cells/mm at 24 weeks and 204 cells/mm at 48 weeks. The percentage of patients with an HIV-1 RNA level < or =400 copies/mL was 87.0% at 24 weeks and 78.8% at 48 weeks. The Kaplan-Meier 1-year survival estimate was 84.7% (79.0%, 90.8%), with a 3.2-fold increased risk (P = 0.004) of mortality among patients with a CD4 cell count <50 cells/mm. The 1-year Kaplan-Meier estimate of toxicity-related drug switches was 32.2% (20.3%, 40.4%). The most common toxicity was peripheral neuropathy, occurring more frequently in patients with a preexisting diagnosis of peripheral neuropathy and among those placed on ddI + d4T-containing regimens. CONCLUSIONS An excellent response to HAART was observed among HIV-1C-infected patients, paralleling those seen elsewhere. Despite excellent responses, high rates of toxicity were observed for ddI + d4T-containing regimens.

Abstract
Botswana, among the countries with the highest HIV/AIDS prevalence rates in the world, has been recognized internationally for its ambitious program to offer voluntary counseling and testing, prevention of mother-to-child transmission (PMTCT) and antiretroviral (ARV) treatment to all residents. Unfortunately, these policies have not been extended to the large numbers of refugees in Botswana. Botswana's Refugee Recognition and Control Act does not recognize a refugee as an ordinary resident.

Abstract
We applied multilocus sequence typing (MLST) to investigate the population structure and mode of reproduction of Cryptococcus neoformans var. grubii (serotype A). This MLST system utilizes 12 unlinked polymorphic loci, which are dispersed on nine different chromosomes, and allows the unambiguous identification of closely related strains of serotype A. We compared MLST analyses with the conventional genotyping method of detecting amplified fragment length polymorphisms (AFLPs), and there was excellent correlation between the MLST and AFLP results. However, MLST differentiated a larger number of strains. We analyzed a global collection of isolates of serotype A using both methods, and the results identified at least three genetically distinct subpopulations, designated groups VNI, VNII, and VNB. Groups VNI and VNII are widespread, dominated by isolates with the MATalpha mating type, and predominantly clonal. Conversely, isolates of group VNB are unique to Botswana, include a significant proportion of fertile strains with the MATa mating type, and manifest compelling evidence of recombination. We have AFLP genotyped >1000 strains of serotype A from different parts of the world, including isolates from several African countries, and, to date, haploid serotype A isolates of group VNB have been found only in Botswana.

Abstract
BACKGROUND In recent years, increasing evidence has accumulated that suggests the majority of cases of genital ulcer disease in sub-Saharan Africa are due to viral and not bacterial infections. Although many cross-sectional studies support such a trend, few serial cross-sectional data are available to show the evolution of genital ulcer disease over time. METHODS We surveyed the prevalence of sexually transmitted diseases (STDs) among patients with STD symptoms and women recruited from family planning clinics in 3 cities in Botswana in 2002 and compared our findings with those from a survey of a similar population conducted in 1993. RESULTS The observed proportion of cases of genital ulcer disease due to chancroid decreased from 25% in 1993 to 1% in 2002, whereas the proportion of ulcers due to herpes simplex virus increased from 23% in 1993 to 58% in 2002. Although the proportion of ulcers due to syphilis was similar for both surveys, the rate of positive serologic test results for syphilis among patients with genital ulcer disease decreased from 52% in 1993 to 5% in 2002. During this period, decreases in the prevalence of gonorrhea, syphilis-reactive serologic findings, chlamydial infection, and trichomoniasis were also detected among patients with STDs and women from family planning clinics. These changes remained significant after estimates were adjusted for the sensitivity and specificity of diagnostic tests. CONCLUSIONS Our findings suggest a decrease in the prevalence of bacterial STDs and trichomoniasis, a reduction in the proportion of ulcers due to bacterial causes, and an increase in the proportion of ulcers due to herpes simplex virus during the period 1993-2002. These changes should be taken into consideration when defining new guidelines for the syndromic management of genital ulcer disease.

Abstract
OBJECTIVES To determine the presence of group A rotavirus in human stool samples in northern Botswana and to characterise the circulating strains. DESIGN A cross sectional study. SETTING The University of Botswana and Botswana-Havard Partnership for HIV Research. SUBJECTS A total of 210 stool samples was collected; 104 from hospitalised and 106 from non-hospitalised children, five years and below suffering from gastroenteritis. RESULTS Out of 210 diarrhoea stool samples collected, 27 (13%) tested positive for group A rotavirus. There was a higher prevalence of infection in hospitalised children (63%) as compared to the non-hospitalised ones (37%). Most rotavirus infections occurred in the age 24 months and below. Of the 13 samples which were positive by PAGE, the predominant electrophoretic pattern detected was the short (S) electrophoretype 9/13 (69%) followed by the long (L) electrophoretype 4/13 (31%). The following G types were detected; G2 (17%), G3 (22%), mixed infections found were G1+G2 (5.6%), G1+G8 (22%), G3+G9 (27.8%) and G1+G3+G9 (5.6%). P[6] was the only VP 4 genotype detected. Rotavirus strains G3P[6] and G3+G9P[6] were identified as the circulating strains in north Botswana. CONCLUSION The detection of uncommon rotavirus strains and the high proportion of mixed infections suggest a greater diversity of rotavirus infections among children in Botswana than previously reported. Our study reveals a complex epidemiological profile of rotavirus infection in Botswana that may require further molecular characterisation.

Abstract
In an effort to assess current and future water quality of the only perennial river in southeastern Botswana, this study presents water quality monitoring and modeling results for the effluent-dependent Notwane River. The water quality along the Notwane River, pre- and post-implementation of secondary wastewater treatment, was compared and results demonstrated that water quality improved after the new wastewater treatment plant (WWTP) went online. However, stream standards for chemical oxygen demand, total dissolved phosphorous, and fecal coliform were exceeded in most locations and the critical dissolved oxygen (DO) reached concentrations of less than 4 mg L(-1). High dissolved P concentrations and intense macrophyte growth at the impounding ponds and at sites within 30 km of the effluent waste stream confluence suggest that eutrophication was a function of P release from the ponds. Results of DO modeling demonstrated that an unpolluted inflow at approximately 10 km downstream of the confluence was responsible for raising DO concentrations by 2.3 mg L(-1), while SOD was responsible for a decline in DO concentrations of 1.4 mg L(-1) at 6 km downstream of the confluence. Simulations also showed higher DO concentrations during winter months, when water temperatures were lower. Simulations, in which the distributed biochemical oxygen demand (BOD) loading from cattle excrement was decreased, produced nominal increases in DO concentrations. An increase in WWTP BOD loadings to projected 2020 values resulted in a 1.3 mg L(-1) decrease in the critical DO concentration. Furthermore, a decrease in treatment plant efficiency, from 94% to 70% BOD removal, produced critical DO concentrations and anoxia along much of the modeled reach. This has significant implications for Gaborone, especially if decreased WWTP efficiency occurs as a result of the expected future increase in pollutant loadings.

Abstract
This paper uses the concept of sustainable development to examine the utilisation of wildlife resources at Moremi Game Reserve (MGR) and Khwai community area (NG 18/19) in the Okavango Delta, Botswana. Using both secondary and primary data sources, results show that the establishment of MGR in 1963 led to the displacement of Khwai residents from their land; affected Basarwa's hunting and gathering economy; marked the beginning of resource conflicts between Khwai residents and wildlife managers; and, led to the development of negative attitudes of Khwai residents towards wildlife conservation. Since the late 1980s, a predominantly foreign owned tourism industry developed in and around MGR, however, Khwai residents derive insignificant benefits from it and hence resource conflicts increased. In an attempt to address problems of resource conflicts and promote sustainable wildlife utilisation, the Botswana Government adopted the Community-Based Natural Resource Management (CBNRM) programme, which started operating at Khwai village in 2000. The CBNRM programme promotes local participation in natural resource management and rural development through tourism. It is beginning to have benefits to Khwai residents such as income generation, employment opportunities and local participation in wildlife management. These benefits from CBNRM are thus having an impact in the development of positive attitudes of Khwai residents towards wildlife conservation and tourism development. This paper argues that if extended to MGR, CBNRM has the potential of minimising wildlife conflicts between Khwai residents and the wildlife-tourism sectors. This approach may in the process promote the sustainable wildlife use in and around MGR.

Abstract
Blood smears and blood lysate samples from freshwater fishes captured in the Okavango Delta, Botswana, were examined to determine whether their trypanosomes were all Trypanosoma mukasai, a species of supposed broad host specificity and widespread existence across Africa. Trypanosomes and/or babesiosomes occurred in 20/32 blood smears, and morphometric analysis of trypanosomes from 13/32 smears showed features suggestive of T. mukasai, including nuclear indices consistently >1. In 16/32 blood lysate samples from which DNA was extracted, trypanosome DNA was detected in 12/16 by PCR (polymerase chain reaction), using trypanosome-specific ssu rRNA gene primers. Two samples positive for trypanosomes in blood smears yielded no amplifiable trypanosome DNA, but 4 samples with no detectable infection in blood smears were positive for trypanosome DNA, suggesting an overall trypanosome prevalence rate of 17/32 (53%) among fishes and demonstrating the value of PCR in trypanosome recognition. Cloning and sequencing of the 12 amplified fragments revealed 2 genotypic groups among these fish trypanosomes. Group 1 trypanosomes were from cichlids and 3 families of catfishes, Group 2 from 2 types of catfishes. Sequence comparison showed that the consensus Group 1 sequence was most similar to that of Trypanosoma cobitis, representing European fish trypanosomes of the carassii type, while the consensus Group 2 sequence showed similarity with a trypanosome sequence from another African catfish, Clarias angolensis. It was concluded that the identification of T. mukasai remains a problem, but at least 2 genotypic groups of trypanosomes occur in Okavango Delta fishes, and catfishes in this region appear to contain both types.

Abstract
A new species of Gyrodactylus von Nordmann, 1832 and the first monogenean reported from Botswana is described from the cichlid Pseudocrenilabrus philander philander, bringing the number of gyrodactylids described from the African Continent to 18. Gyrodactylus thlapi n. sp. can be readily discriminated from the other described species almost exclusively by the shape of its hamuli, which have short roots and large, elongate ventral bar attachment points with the dorsal bar attachment point, demarcating the junction between the hamulus shaft and the root, positioned at the anterior terminus of the attachment plane. The marginal hooks of G. thlapi n. sp., which most closely resemble those of G. groschafti Ergens, 1973, are compared and discussed.

Abstract
This qualitative study was conducted to understand and theoretically explain infertility from the perspective of 40 infertile women and four members of the traditional health care system. Symbolic interaction and feminism were combined to under-gird the study. Through ongoing data collection and analysis, a theoretical framework of denying and preserving self was constructed. Preserving self or self-preservation means developing personal measures aimed at preventing o rreducing harm inflicted by others as a result of one's infertility. Contributory factors to denying of self include denial of status as a woman; denial of immortality; denial of experiences of pregnancy, labour and delivery; denial of economic and social security; and the belief that they are being chastised by God and the forefathers. In addition, the women develop strategies to deal with such denials by looking for deeper meaning, working it out, giving in to feelings, getting more involved, getting away, and doin gadoption. Implications of the study are discussed.

Abstract
BACKGROUND The ability of highly active antiretroviral therapy (HAART) to reduce human immunodeficiency virus type 1 (HIV-1) RNA and DNA in breast milk has not been described. METHODS We compared breast-milk HIV-1 RNA and DNA loads of women in Botswana who received HAART (nevirapine, lamivudine, and zidovudine) and women who did not receive HAART. RESULTS Women in the HAART group received treatment for a median of 98 days (range, 67-222 days) at the time of breast-milk sampling; 23 (88%) of 26 had whole breast-milk HIV-1 RNA loads <50 copies/mL, compared with 9 (36%) of 25 women who did not receive HAART (P=.0001). This finding remained significant in a multivariate logistic-regression model (P = .0006). The whole-milk HIV-1 DNA load was unaffected by HAART. Of women who received HAART, 13 (50%) of 26 had HIV-1 DNA loads <10 copies/10(6) cells, compared with 15 (65%) of 23 who did not receive HAART (P = .39). CONCLUSIONS HAART suppressed cell-free HIV-1 RNA in breast milk and may therefore reduce mother-to-child transmission (MTCT) of HIV-1 via breast-feeding. However, HAART initiated during pregnancy or early after delivery had no apparent effect on cell-associated HIV-1 DNA loads in breast milk. Clinical trials to determine MTCT among breast-feeding women receiving HAART are needed.

Abstract
BACKGROUND The magnitude of infant antiretroviral (ARV) exposure from breast milk is unknown. METHODS We measured concentrations of nevirapine, lamivudine, and zidovudine in serum and whole breast milk from human immunodeficiency virus type 1 (HIV-1)-infected women in Botswana receiving ARV treatment and serum from their uninfected, breast-feeding infants. RESULTS Twenty mother-infant pairs were enrolled. Maternal serum concentrations of nevirapine were high (median, 9534 ng/mL at a median of 4 h after nevirapine ingestion). Median breast-milk concentrations of nevirapine, lamivudine, and zidovudine were 0.67, 3.34, and 3.21 times, respectively, those in maternal serum. The median infant serum concentration of nevirapine was 971 ng/mL, at least 40 times the 50% inhibitory concentration and similar to peak concentrations after a single 2-mg/kg dose of nevirapine. The median infant serum concentration of lamivudine was 28 ng/mL, and the median infant serum concentration of zidovudine was 123 ng/mL, but infants were also receiving zidovudine prophylaxis. CONCLUSIONS HIV-1 inhibitory concentrations of nevirapine are achieved in breast-feeding infants of mothers receiving these ARVs, exposing infants to the potential for beneficial and adverse effects of nevirapine ingestion. Further study is needed to understand the impact of maternal ARV treatment on breast-feeding HIV-1 transmission, infant toxicity, and HIV-1 resistance mutations among infected infants.

Abstract
Cryptococcus gattii is a group of exogenous, neurotropic yeasts that possess the capsular serotype B or C. Isolates of serotype C are extremely rare and, until recently, were known to infect only immunocompetent individuals. We genotyped 176 isolates of Cryptococcus from patients in sub-Saharan Africa who had AIDS; 22 (13.7%) of 161 isolates from Botswana and 2 (13.3%) of 15 isolates from Malawi were C. gattii serotype C strains. All of these serotype C strains belong to the rare VGIV genotype, possess the MAT alpha mating-type allele, and exhibit little genetic diversity.

Abstract
The concern for ethical principles and values is not limited to health professionals alone. However, ethical principles in nursing act as safety valves for social control to prevent professional misconduct and abuse of the rights of clients. As a result of colonial experience, developing countries like Botswana usually follow the European lead, especially examples from the UK. This article examines the ethical problems and dilemmas associated with rural nursing practice in Botswana, a developing country in sub-Saharan Africa. The major ethical problems identified are related to the distribution of and access to health resources in rural communities. It is proposed that nurses must assume responsibility in the field of access and allocation by working collaboratively with governments and other professional bodies, and that nurses as a global community must work together as a team to support each other.

Abstract
BACKGROUND We conducted a pharmacokinetic study of antimycobacterial drugs involving a cohort of patients with pulmonary tuberculosis (TB) in Gaborone, Botswana, to assess the prevalence of and risk factors for low drug concentrations in serum. METHODS Adults participated if they had a history of cough > or =2 weeks, had abnormal chest radiograph findings, consented to testing for human immunodeficiency virus (HIV), had sputum cultures positive for Mycobacterium tuberculosis, and were receiving antituberculous therapy for >7 days. Observed maximum serum concentrations were compared with published normal ranges. RESULTS. Of 91 patients enrolled, 89 (98%) were outpatients, and 59 (68%) of 87 patients tested had HIV infection. The following numbers of patients had low serum concentrations of the following drugs: isoniazid, 27 (30%) of 90; rifampin, 71 (78%) of 91; ethambutol, 37 (41%) of 91; and pyrazinamide, 1 (1%) of 91. Low serum concentrations of both isoniazid and rifampin occurred in 23 (26%) of 90 patients. Low serum concentrations of rifampin were found in both HIV-infected and non-HIV-infected patients, and such patients were less likely to have >4 weeks of symptoms, more likely to have lymphadenopathy, and more likely to have low serum albumin levels (P<.05 for all). The associations with noncavitary pulmonary disease (P=.12) and HIV infection (P=.07) did not reach statistical significance. Delayed absorption was most common with ethambutol, followed by rifampin. CONCLUSIONS These data, predominantly from HIV-infected patients with TB, suggest that low isoniazid, rifampin, and ethambutol concentrations are common in Botswana. In contrast, pyrazinamide usually is well absorbed.

Abstract
The results discussed in this report are part of a larger study conducted among the students of the University of Botswana regarding their knowledge, attitudes, and behaviors related to HIV/AIDS. The study triangulated survey methods and focus group discussions. Five main areas were investigated: knowledge and personal experiences of HIV/AIDS, sexual behavior and practices, perceptions about risky sexual behavior on campus, and factors that influence the spread of HIV. This article reports high levels of risky behaviors such as alcohol and drug abuse; unprotected sex; frequent change of sexual partners; sex for financial gain, for prestige, for good grades, to relieve stress, and because of peer pressure; and casual sex as part of socializing.

Abstract
The existence of gender-based violence has been a source of concern within the public and private sectors as well as civil society organisations in Botswana. The present study investigated the link between alcohol abuse, gender-based violence and HIV/AIDS. Further, it attempted to unravel the often unquestioned assumption that gender-based violence is perpetuated by cultural practices. Case study qualitative methodology was used to gather data for the study. A sample of 20 cases was selected purposively from five women's non-governmental organisations. In addition, in-depth interviews were conducted with agency coordinators, social workers, police commanders and police officers. The findings of the study revealed a relationship between alcohol abuse and gender-based violence, which makes victims vulnerable to HIV infection. From the findings, it is recommended that gender-based programmes be established to sensitise people about the link between alcohol abuse, gender-based violence and HIV/AIDS.
