RESUMO

INTRODUCTION: Community-acquired acute bacterial pneumonia (ABP) is an acute, non-suppurative, non-tuberculosis lower respiratory infection of the lung parenchyma acquired within the community. They have an atypical clinical presentation and a poor prognosis in the elderly. MATERIALS AND METHODS: This was a prospective cross-sectional study conducted in the Pneumology department of the University Hospital Center (CHU) of Point-G, from October 30, 2018 to September 30, 2019. The objective was to determine the clinical, etiological, therapeutic and progression of BAP in the elderly. Were included any age ≥ 65 years, presenting clinical and radiological signs of a PAB. RESULTS: During the study period, 85 patients met the inclusion criteria out of 178 hospitalized. The sex ratio was 3/1. About 2/3 were smokers and 11% were HIV positive. Fever was not constant recorded in 51.76% of cases. Respiratory signs were dominated by cough (96.47%), dyspnea (94.11%) and extra respiratory by impaired consciousness. Klebsiella pneumoniae was the most found germ. The most commonly used antibiotic was amoxicillin-clavulanic acid. The average length of hospitalization was 9 days. Mortality was 19%. CONCLUSION: The PAB in the elderly is of a frustrating clinical symptomatology. It is serious with excess mortality.

RESUMO

The lack of data on neonatal tetanus and children in university hospitals (UH) in Abidjan for over a decade has motivated the realization of this study. The objective of this study is to evaluate the morbidity and mortality related to neonatal tetanus (NT) and child tetanus (CT) in Abidjan University Hospital from 2001 to 2010. It is a retrospective study, multicenter analysis with records of newborns and children suffering from tetanus in the three UH of Abidjan. The collection and analysis of data were made by the SPHINX 4.5 and EPI.INFO 6.0 software. In ten years, 242 cases of tetanus (53 NT cases and 189 CT cases) were collected with a predominance of cases after the fifth year of life (59.5%). The incidence rate of NT was less than 1 case per 1,000 live births. All mothers of the newborns were inhabiting the city of Abidjan. Their median age was 19 years [16-32] and 64% were teenagers. Gateways were dominated by umbilical wounds (77.3%) in the NTand skin wounds (59%) in CT. The cure rate was 30.2% in the NT and 60% in the CT. Lethality was 60% for NT and 22% for CT with a positive correlation with young age (neonates: p = 4.10-7, age <5 years: p = 0.01), lack of intraspinal injection of tetanus serum (p = 8.10-6), the absence of conventional antibiotic therapy (p = 0.023), the existence of metabolic complications (p = 2.10-5), the score of ≥ 4 Dakar (p = 0.005). Tetanus remains a real morbidly cause among children in Abidjan University Hospital with high lethality. However, the incidence of NT seems consistent with the incidence threshold desired by WHO.

RESUMO

OBJECTIVE: To determine the prevalence of psychiatric disorders in a prison population in Abidjan (Côte d'Ivoire). PATIENTS AND METHODS: This was a descriptive cross-sectional study, conducted from June to August 2008 at the Medical Department of the Prison and Correctional Center of Abidjan (PCC). 200 inmates were interviewed following the completion of a MINI supplementing a questionnaire on sociodemographic and penitentiary data. RESULTS: The prison population of this study was predominantly male (90%) with a mean age of 33 years. Nearly half of the prisoner were single and without children (52.5%) and serving their first incarceration (54%); 76.5% of the inmates had completed at least 12 months in detention. The study found that 76% of prisoners had a DSM IV Axis I psychiatric disorder. The prevalence of major depressive episodes was 50.5% with an estimated 38.5% suicide risk. 23% had antisocial personality and 11% of respondents displayed a psychotic syndrome. Illicit drugs were found in 14% of prisoners and abuse of these drugs was reported by 17% of them. 8% had a state of post-traumatic stress and 3.5% obsessive compulsive disorder. CONCLUSION: The high prevalence of psychiatric morbidity in the prison settings argues in favor of a better organization of medical and psychological assistance to inmates.


OBJECTIF: Déterminer la prévalence des troubles psychiatriques dans une population carcérale à Abidjan (Côte d'Ivoire). PATIENTS ET MÉTHODE: Il s'agissait d'une étude descriptive réalisée de Juin à Août 2008 au Service Médical de la Maison d'Arrêt et de Correction d'Abidjan (MACA). 200 détenus ont été interviewés à partir duMINI complété d'un questionnaire relatif aux données sociodémographiques et carcérales. RÉSULTATS: La population carcérale de notre étude était majoritairement masculine (90%) avec une moyenne d'âge de 33 ans. Un détenu sur deux était célibataire sans enfant (52,5%) et primo-incarcéré (54%) ; 76,5% des détenus avaient au moins 12 mois de détention. L'étude a révélé que 76% des détenus présentaient un trouble psychiatrique de l'axe I du DSM IV. La prévalence d'épisode dépressif majeur était de 50,5% avec un risque suicidaire estimé à 38,5%. 23% présentaient une personnalité antisociale et 11% des interviewés présentait un syndrome psychotique. La dépendance aux drogues illicites existait chez 14% des détenus et l'abus de ces drogues était déclaré par 17% d'entre eux. 8% souffraient d'un état de stress post-traumatique et 3,5% d'un trouble obsessionnel compulsif. CONCLUSION: La prévalence élevée de la morbidité psychiatrique en milieu carcéral milite en faveur d'une meilleure organisation de l'assistance médico-psychologique des détenus.

RESUMO

Xanthomonas citri pv. mangiferaeindicae causing bacterial canker (or black spot) is a major mango (Mangifera indica L.) pathogen in tropical and subtropical areas (3). The bacterium infects a wide range of mango cultivars, and induces raised, angular, black leaf lesions, sometimes with a yellow chlorotic halo. Fruit symptoms first appear as small water-soaked spots on the lenticels turning into star-shaped, erumpent lesions, which exude an infectious gum, yielding tear-stain patterns. Severe infections cause severe defoliation and/or premature fruit drop. Twig cankers are potential sources of inoculum and weaken branch resistance to winds. Drastic yield losses have been reported at grove scale for susceptible cultivars (3). Mango leaves showing typical angular, black, raised leaf lesions were first observed and collected in April 2014 from trees cv. Kent in five localities of the Korhogo province of Ivory Coast (i.e., the major commercial mango-growing area in this country). Non-pigmented Xanthomonas-like colonies were isolated on KC semi-selective medium (4). Five strains (LL60-1, LL61-1, LL62-1, LL63-1, and LL64-1), one from each locality, were compared by multilocus sequence analysis (MLSA) to the type strain of X. citri and the pathotype strain of several X. citri pathovars, including pvs. anacardii and mangiferaeindicae. This assay targeted the atpD, dnaK, efp, and gyrB genes, as described previously (2). Nucleotide sequences were 100% identical to those of the pathotype strain of X. citri pv. mangiferaeindicae whatever the gene assayed, but differed from any other assayed X. citri pathovar. Leaves of mango cv. Maison Rouge from the youngest vegetative flush were infiltrated (10 inoculation sites/leaf for three replicate leaves on different plants/bacterial strain) as detailed previously (1) with the same five strains. Bacterial suspensions (~1 × 105 cfu/ml) were prepared in 10 mM Tris buffer (pH 7.2) from 16-h-old cultures on YPGA (7 g yeast, 7 g peptone, 7 g glucose, and 18 g agar/liter, pH 7.2). The negative control treatment consisted of three leaves infiltrated with sterile Tris buffer (10 sites/leaf). Plants were incubated in a growth chamber at 30 ± 1°C by day and 26 ± 1°C by night (12-h day/night cycle) at 80 ± 5% RH. All leaves inoculated with the strains from Ivory Coast showed typical symptoms of bacterial canker a week after inoculation. No lesions were recorded from the negative controls. The pathogen was recovered at high population densities (>1 × 106 cfu/lesion) from leaf lesions, typical of a compatible interaction (1) and isolated colonies were identified as the target by atpD sequencing (2). Koch's postulates have therefore been fully verified. This is the first report of the disease in Ivory Coast, a country which has been an internationally significant mango exporter (up to 15,000 tons per year) over the last two decades. A high disease incidence and severity were observed, outlining the need for implementing integrated pest management in mango groves and the production of disease-free nursery stock. This report further expands the distribution of the pathogen in West Africa after its first description from Ghana in 2011 (5) and subsequently in other neighboring countries. References: (1) N.

RESUMO

The genetic and phenotypic diversity of Côte d'Ivoire Ralstonia solanacearum strains was assessed on a 168-strain collection sampled on Solanaceae both in the southern lowlands and western highlands. Phylotypes I, II, and III were prevalent, though at unexpected frequencies. Phylotype I strains (87.5%) were genetically diverse and overrepresented in all agroecological areas, including highlands (AEZ III). Phylotype II strains (10.7%) only belonged to one tropical lowland-adapted broad host range lineage (IIA-35), whereas no highland-adapted potato brown rot (IIB-1) or Moko strains were detected. African phylotype III strains were rare (1.8%). They originated from a single Burkina Faso lineage (III-23) and were only found in lowlands. Three phylotype I strains were found harboring pRSC35, a plasmid identified in phylotype III strains in Cameroon. From pathogenicity tests performed on commercial varieties and tomato/eggplant/pepper references, the virulence diversity observed was high, with five pathoprofiles described. Eggplant accessions MM152 and EG203 and tomato HW7996 displayed the largest resistance spectrum and highest level. Two highly virulent phylotype I strains were able to bypass resistance of HW7996 and the eggplant reference AG91-25. Collectively, these points lead to the conclusion that the situation in Côte d'Ivoire is specific towards other African countries, and specifically from the Cameroon reference, and that within phylotype I can exist a high virulence diversity. This calls for similar studies in neighboring West African countries, linking R. solanacearum pathogen genetic diversity to strain virulence at the regional level, for the rationalization of regional resistance deployment strategies and future resistance durability studies.

RESUMO

BACKGROUND: There is insufficient research into the state of paediatric oncology in African countries. OBJECTIVES: The purpose of this study was to analyse the state of paediatric oncology between 1995 and 2004 in Côte d'Ivoire. METHODS: This retrospective descriptive study analysed all patients under the age of 18 who were diagnosed with cancer in Côte d'Ivoire over a period of 10 years (January 1995 - December 2004) with regard to demographics, types of pathology, delay in diagnosis and treatment, treatment modalities, abandonment of treatment and survival rate. RESULTS: Of 405 patients diagnosed with cancer, 331 were included in the study. Burkitt's lymphoma was the most common malignancy (73.6%), followed by nephroblastoma (14.5%) and acute leukaemia (4%). Delay in diagnosis occurred in 38.7% of cases and ranged from 1 to 3 months; the average delay from diagnosis to starting treatment was 18 days. An abdominal mass and swelling of the jaw were the most common clinical presentations. Almost half of the patients (48.6%) were lost to follow-up and over a third (39.3%) died shortly after admission owing to advanced disease. The overall survival rate was 9.4%. CONCLUSIONS: Cancer in children in Côte d'Ivoire was dominated by Burkitt's lymphoma. The rate of loss to follow-up of almost 50% is grounds for concern. The overall survival rate of 9.4% is very low, but such figures are not uncommon for African countries. Collaboration within the Franco-African Group of Paediatric Oncology has contributed to improving the management of children with cancer.

RESUMO

A research program was initiated at the University of Georgia in 2003 to identify banana cultivars suitable for production in the coastal and southern areas of the state. During a root disease survey conducted in October 2007 on bananas (Musa spp.) grown at the University of Georgia Bamboo Farm and Coastal Gardens in Savannah, GA, root lesions and root rot were observed on banana cvs. Gold Finger, Kandarian, and Manzano. Root lesions were dark brown to black and irregular in shape, with partial or entire roots affected. Lateral roots and outer layers of cord roots (roots arising from interior layers of the corm) of infected plants were blackened and rotted. Diseased root samples were collected from three plants of each cultivar, surface sterilized with 0.6% sodium hypochlorite, and placed on tannic acid benomyl agar (TABA). Pure cultures of the fungus consistently associated with diseased tissue were obtained by subculturing hyphal tips on TABA. Mycelia of the fungus on potato dextrose agar (PDA) were light to deep brown and the hyphae tended to branch at right angles. A septum was present in each hyphal branch near the point of origin and a slight constriction at the branch was observed. The hyphae of two isolates were stained with 0.6% phenosafranin and 3% KOH and binucleate hyphal cells were observed. On the basis of these morphological features, the isolates appeared to be binucleate Rhizoctonia anamorphs (teleomorph Ceratobasidium Rogers). For molecular identification, the internal transcribed spacer (ITS) regions and the 5.8S gene from rDNA of the isolates were cloned and sequenced (GenBank Accession No. HQ168370). The ITS regions (775 bp) were 100% identical between the two isolates and 99% identical to Ceratobasidium sp. AG-F strain SIR-1 isolated from sweet potato in Japan (GenBank Accession No. AF354085). The anastomosis group of the isolates was confirmed by pairing with strain SIR-1 on PDA. On the basis of morphological and molecular characteristics and the anastomosis assay, the two isolates were identified as a Ceratobasidium sp. AG-F (1-3). Pathogenicity assays were conducted by inoculating banana plants (cv. Golden pillow, synonym = Manzano) grown in pots under greenhouse conditions (25 to 27°C). Twenty wheat seeds infested with each isolate were placed uniformly around each plant at a depth of 10 cm in the soil. The plants were incubated in the greenhouse and the roots were examined 2 months after inoculation. Brown-to-black lesions and root rot, identical to symptoms associated with field banana roots, were observed on all inoculated plants but not on the noninoculated control plants. The fungus was reisolated from affected root samples and the identity was confirmed by morphological and molecular characteristics and the anastomosis assay. To our knowledge, this is the first report of banana root rot caused by binucleate Rhizoctonia anastomosis group F. With the increased interest in producing bananas for food and ornamental purposes, the occurrence of Ceratobasidium root rot on bananas needs to be considered when designing disease management programs and searching for suitable cultivars for banana production.

RESUMO

AIM: Pregnant women HIV infection has main risk the contamination of newborn. MTCT actions permit to reduce that risk. MATERIAL AND METHODS: Our survey has been realized in Gabriel Touré teaching hospital gynecology and obstetrics and pediatric departments. It is about an observational prospective and descriptive survey that spreads on a period from January 2005 to December 2008. Has been included in the study all the HIV positive pregnant women followed in our service and their babies that had received ARV prophylaxis and 18 months of life serology. RESULTS: We recorded 211 HIV positive pregnant women on a total of 9291 childbirths (2.27%). We noted 90.52% of HIV-1 vs 7.11% of type 2. The mother treatment consisted in a tri therapy in 77.25 vs 0.47% of bi anti retroviral and 22.28% of mono anti retro viral therapy. Maternal viral load was undetectable at the moment of delivery in 78.20% of cases. We noted vaginal delivery in 84.36% vs 15.64% of caesarean section. Newborns respectively received 67.32%; 4.88% and 22.92% of bi, tri and mono therapy. They formula-fed in 98.98%. The mother to child HIV transmission rate was 1.98%. CONCLUSION: HIV prevalence in pregnant patients is relatively height. HARRT in HIV positive mothers associated to bi therapy and formula feeding to their infants permit to obtain low vertical HIV transmission rate.

RESUMO

OBJECTIVE: The aim of our study was to describe current ultrasound and epidemiological features of ectopic pregnancy in Abidjan, Côte d'Ivoire. PATIENTS AND METHODS: This prospective study was carried out over a 24-month period (February 2006 to January 2008) at Nanglé Medical Clinic, i.e., a private clinic located in Abidjan's Yopougon suburb. RESULTS: A total of 32 cases of ectopic pregnancy were discovered by suprapubic and/or endovaginal ultrasound scan. The estimated frequency of ectopic pregnancy was 1.7%. Mean patient age was 26.2 years. The main risk factors were prior history of abortion (32%) and adnexal infection (20%). Most patients (52.5%) were nulliparous. The most frequent indication for ultrasound scan was metrorrhagia. Diagnosis of ectopic pregnancy was made at the ruptured stage in 65.6% of cases and nonruptured stage in 34.4%. The presenting lesions was hematosalpinx in 40.6% of cases and embryonate ectopic gestational sac in 31.3%. Salpingectomy and salpingorrhaphy were successful in 65.6% and 34.4% of cases respectivlely. CONCLUSION: In Abidjan, ectopic pregnancy involves young nulliparous women with a prior history of abortion and adnexal infection. Ultrasound allowed early diagnosis and, consequently, tube preservation in 34.4% of cases.

RESUMO

Southern blight caused by Sclerotium rolfsii Sacc. was observed on okra (Abelmoschus esculentus) cv. Clemson Spineless in January 2010 during a survey of vegetable fields in Rubbino, Côte d'Ivoire, which is one of the most important areas for vegetable production. Plants exhibited symptoms of a dark brown lesion on the stems near the soil line. Upper roots became light to dark brown, the lower leaves wilted, turned yellow, and a white mat of fungal mycelium developed on the stem lesion. Numerous, white, spherical sclerotia formed on the infected stem and on soil surfaces around the infected plants. Sclerotia (0.5 to 1.2 mm in diameter) later turned tan to dark brown and the entire plant wilted. Eleven fields, with a total of approximately 26 ha surveyed, were affected and disease incidence reached approximately 15% in the fields. Sclerotia were collected and the fungus cultured on acidified potato dextrose agar (PDA) plates. The fungus grew rapidly on PDA and the hyphae at the edge of the colonies were large straight cells with one or more clamp connections at each septum. Secondary and tertiary hyphae were slender and lacked clamp connections. Whitish sclerotia were observed on the mycelial mats 5 to 7 days after incubation, which later turned tan to brown when mature. The fungus was identified as S. rolfsii based on the characteristics of mycelia and sclerotia (1). Sclerotia produced on PDA were used to inoculate okra seedlings under greenhouse conditions at rates of 10, 20, and 30 sclerotia per plant. Sclerotia were placed just under the soil surface around the root of 4-week-old seedlings of okra cv. Clemson Spineless. Symptoms identical to those on field samples developed on all inoculated plants. S. rolfsii was reisolated from diseased plants and the identity was confirmed. S. rolfsii has previously been reported as causing disease in Côte d'Ivoire (2). To our knowledge, this is the first report of southern blight caused by S. rolfsii on okra in this country. Okra is an important vegetable crop in Côte d'Ivoire and therefore the occurrence of southern blight and susceptibility of okra cultivars to this disease needs to be taken into account in okra production.

RESUMO

During a field survey conducted in December 2008 and January 2009 in southern Ivory Coast, zucchini squash (Cucurbita pepo L.) and cucumber (Cucumis sativus L.) plants were observed showing severe symptoms of leaf mosaic and distortions, filiformism, and fruit deformations. Nine samples were collected from symptomatic plants in four locations (Adzopé, Songon, Ayamé, and Gagnoa) and dried over CaCl2. Double-antibody sandwich (DAS)-ELISA tests were performed directly on dried samples with antisera against nine cucurbit-infecting viruses: Zucchini yellow mosaic virus (ZYMV, Potyvirus); Papaya ringspot virus (PRSV, Potyvirus); Watermelon mosaic virus (WMV, Potyvirus); Moroccan watermelon mosaic virus (MWMV, Potyvirus); Cucumber vein yellowing virus (CVYV, Ipomovirus); Cucumber mosaic virus (CMV, Cucumovirus); Cucurbit aphid borne yellows virus (CABYV, Polerovirus); Squash mosaic virus (SqMV, Comovirus); and Cucumber green mottle mosaic virus (CGMMV, Tobamovirus). ZYMV was detected alone in four of six zucchini squash samples and in mixed infection with CMV and PRSV in two of three cucumber samples. A cucumber sample (CI09-09) collected at Songon and infected by ZYMV, CMV, and PRSV was inoculated to zucchini squash. ZYMV was separated from CMV and PRSV by inoculating zucchini squash plantlets with one Myzus persicae Sulzer per plant with 2-min acquisition and 2-h inoculation access periods. Plants infected by ZYMV only developed typical symptoms of severe mosaic, distortion, and filiformism on leaves. Total RNA was extracted from the original dried sample of CI09-09 using TRI-Reagent (Molecular Research Center Inc., Cincinnati, OH) (2). One-step reverse transcription (RT)-PCR was performed with our standard protocol and specific primers (2), yielding a 605-bp fragment corresponding to part of the polymerase (NIb) and coat protein (CP) coding regions. The nucleotide sequence of the NIb-CP fragment of Ivory Coast ZYMV isolate CI09-09 (GenBank No. HM450303) shared 98.5, 92.7, 80.5, and 75.7% identity with ZYMV isolates from France (isolate E9, HM641798), Florida (D13914), Singapore (AF014811), and Vietnam (DQ925449), respectively. Sequence comparison indicated that CI09-09 belongs to the phylogenetic cluster 1 of group A of ZYMV (2). ZYMV, first described in 1981, is now one of the most damaging viruses in cucurbit crops worldwide and is characterized by an important biological and molecular diversity (1,3). ZYMV has already been reported in several African countries, mostly in the northern and southern parts of the continent (1), but to our knowledge, this is the first report of ZYMV in Ivory Coast. Among African isolates, CI09-09 shared 97.5% identity with isolate Su06-22 from Sudan (HM641799) belonging to the phylogenetic cluster 1 of group A of ZYMV, 94 to 95% identity with isolates from neighboring Mali (HM005307-HM005312) belonging to cluster 2 of group A, and 79.6% identity with the divergent isolate R5A from Réunion Island (L29569) belonging to phylogenetic group B of ZYMV. The presence of ZYMV in four distant locations in southern Ivory Coast suggests that this virus constitutes a serious threat to cucurbit production in this country. References: (1) C. Desbiez and H.

RESUMO

Black spots were observed on the leaves of bananas (Musa spp.) grown at the University of Georgia Bamboo Farm and Coastal Gardens in Savannah, GA in November 2007. Symptoms occurred on more than 60 plants, representing 16 of 34 cultivars of bananas investigated. Most lesions were less than 10 mm in diameter and tan to black. However, larger oval lesions more than 20 mm across with black borders and yellow halos also occurred. Lesions were more prevalent on older leaves. On young leaves, lesions first appeared along the leaf margin near the tip of the leaf on one side of the central vein. Lesions expanded to the entire leaf as the disease progressed, but were more prevalent along leaf margins. Thirty-two diseased leaf samples, two from each cultivar, were incubated at 25°C in the dark and conidia were produced on the lesions 2 days after incubation. Pure cultures of the fungus were obtained from five leaf samples by single-spore culturing on potato dextrose agar medium and identified on the basis of morphological characteristics. Conidia on V8 agar are straight or slightly curved, obpyriform to obclavate, and olive to brown with 3 to 13 septa. Conidiophores are brown and swollen at the apex. The fungus was identified as Deightoniella torulosa (Syd.) Ellis on the basis of morphological characteristics described previously (1,2). Pathogenicity studies to fulfill Koch's postulates were conducted on banana cvs. Dwarf Namwah and Dwarf Nino under greenhouse conditions (25 to 27°C). Six plants of each cultivar were used in one experiment and the experiment was repeated one more time. Banana leaves were inoculated by spraying with a suspension of conidia from a pure culture. Symptoms developed as small black lesions on the leaves of both cultivars within 1 week of inoculation. As the disease progressed, some of the small lesions expanded to form larger oval lesions. Symptoms were identical to those on the field samples and were identified as the black spot disease as described on abaca and banana (2). The fungus was reisolated from symptomatic leaves and the identity was confirmed. No symptoms were observed on noninoculated control plants. The black spot disease has been reported in Florida attacking banana and plantain (3). To our knowledge, this is the first description of the presence of the disease on field-grown banana in Georgia. In recent years, increasing efforts have been made in Georgia in the search of banana cultivars suitable of commercial production in the coastal and southern areas of the state. Black spot of banana is an important disease and its occurrence deserves consideration in evaluating banana cultivars and developing disease management approaches for banana production in Georgia.

RESUMO

This study investigated the possibility of recycling nutrients in human excreta and municipal solid waste for use in agriculture. It reports on the use of drying beds in separating solid and liquid fractions of faecal sludge (FS) so that the solids can be co-composted and the organic matter and part of the nutrients captured for urban agriculture. Sludge influent onto drying beds, percolate effluent, and dewatered sludge (biosolids) were monitored over eight loading cycles in 2002. The unplanted drying beds were made of 15 cm of sand (0.2-0.6mm diameter) and 25 cm gravel (10 and 19 mm diameter). The loading rate of sludge ranged from 196 to 321 kg total solids (TS) /m(2)y. Biosolids with TS 20% were obtained after an average drying time of 2 weeks. The drying beds retained 80% of solids and 100% of helminth eggs. The biosolids had average organic matter content of 61%; hence, allowing for co-composting with biodegradable organic solid waste for hygienisation. The process is being investigated further to attain higher efficiency and reliability.

RESUMO

To get rid efficiently of anaerobics bacteria, which constituted the flora associated to periodontitis, the periodontal therapy is now moving towards 2 or 3 antibiotics association. The aim of this study is to make a comparison between the efficacy of the association of amoxicillin plus clavulanic acid and that of amoxicillin plus metronidazole into 20 patients suffering from rapidly progressive periodontitis. The results have shown that both forms of antibiotics association are efficacious in rapidly progressive periodontitis treatment, with the same action on clinical parameters.

RESUMO

Waste stabilization ponds (WSP) are an often-used option to treat faecal sludges collected from on-site sanitation systems. Since agricultural use is one of the most attractive options for sludge disposal, specific guidelines on the hygienic sludge quality must be fulfilled, such as for viable helminth eggs and Salmonella sp. Although Salmonella isolation methods are well known for other types of samples, they are not suitable for faecal sludge. The reason can be attributed to the co-existence of a native bacterial sludge flora masking Salmonella development, especially if this bacteria is present at low concentrations. In order to select the best methodology for Salmonella recovery from septage sludge, different culture media were assayed at different incubation periods and temperatures. The proposed methodology for Salmonella recovery from sludge can be summarised as follows: (1) enrichment in Rappaport-Vassiliadis broth at 43 degrees C, 48 hours, and (2) isolation in XLD agar at 40 degrees C, 24 hours. Identification of suspected colonies by biochemical tests: TSI, LIA, urease and serological confirmation with Group O Antigen.

RESUMO

In tropical regions, where most of the developing countries are located, septic tanks and other onsite sanitation systems are the predominant form of storage and pre-treatment of excreta and wastewater, generating septage and other types of sludges. The septage is disposed of untreated, mainly due to lack of affordable treatment options. This study presents lessons that have been learned from the operation of pilotscale constructed wetlands (CWs) for septage treatment since 1997. The experiments have been conducted by using three CW units planted with narrow-leave cattails (Typha augustifolia) and operating in a vertical-flow mode. Based on the experimental results, it can be suggested that the optimum solids loading rate be 250 kg TS/m2 yr and 6-day percolate impoundment. At these operational conditions, the removal efficiencies of CW units treating septage at the range of 80-96% for COD, TS and TKN were achieved. The biosolid accumulated on the CW units to a depth of 80 cm has never been removed during 7 years of operation, but bed permeability remained unimpaired. The biosolid contains viable helminth eggs below critical limit of sludge quality standards for agricultural use. Subject to local conditions, the suggested operational criteria should be reassessed at the full-scale implementation.
