“…Bacterial growth was identified using standard methods. 31,32 Gram-negative non-fermenting bacteria, that is, Acinetobacter sp, Achromobacter sp, Alkaligenes sp, Pseudomonas sp other than Aeruginosa and Flavobacterium are of doubtful pathogenicity in a population without severe immunosuppression or in-dwelling foreign bodies, and were considered contaminants, in addition to common skin flora, such as coagulase negative Staphylococci, Diphtheroids, Bacillus sp and Micrococci. Antimicrobial susceptibility tests were performed as previously reported.…”

Objective: To determine the bacterial etiology, clinical presentation and risk factors for outcome of serious community-acquired infections in young infants.Study Design: Infants younger than 60 days, admitted for severe pneumonia or suspected sepsis/meningitis were prospectively evaluated using complete blood count, blood culture, chest radiograph, cerebrospinal fluid (CSF) culture in suspected meningitis. w 2 or Fisher's exact test and stepwise logistic regression were used for analysis.Results: Thirty-four of 767 enrolled infants had a positive blood or CSF culture. Gram-negative bacteria were more frequent than Gram positive: overall (P ¼ 0.004), in those below 7 days of age (P ¼ 0.002) and among home deliveries (P ¼ 0.012). Case fatality rates were higher among infants below 1 week old (OR 4.14, P<0.001), those with dense (OR 2.92, P<0.001) or diffuse radiographic infiltrates (OR 2.79, P ¼ 0.003).Conclusions: Gram-negative enteric bacteria are the predominant causes of community-acquired infections in Filipino infants below 2 months old. Age below 7 days and radiographic pneumonia predicted death.

SUMMARYThe presence of Salmonella enterica and serologic evidence of infection by Leptospira interrogans, were detected in the opossum Didelphis virginiana in a semi-urban locality of the Yucatán State, México. Ninety-one opossums were captured during the period April 1996 and May 1998. From a total of 17 feces samples, four Salmonella enterica subsp. enterica serotypes (Sandiego, Newport, Anatum, and Minnesota), and one Salmonella enterica subsp. arizonae serovar O44: Z4,Z23:-were isolated. Some opossums presented mixed infections. From 81 sera samples, four (4.9%) were positive to antibodies to Leptospira serovars pomona and wolfii. Both animals infected with Salmonella enterica and those serologically positive to Leptospira interrogans were captured in peridomestic habitat. Opossums infected with Salmonella enterica, were captured in dry season, and those seropositive to Leptospira interrogans during the rainy season. The implications of infection and reactivity of these zoonotic pathogens in D. virginiana in the Yucatan state are briefly discussed. KEYWORDS: Didelphis virginiana; Salmonella enterica; Leptospira interrogans; Yucatán; México.Opossums of the genus Didelphis have been frequently found infected with several zoonotic diseases 7 . Didelphis virginiana occurs widely in México including the Yucatán Peninsula where this opossum is abundant in the peridomestic habitat, thus bringing a risk to transmit zoonotic diseases such as Chagas disease to the human populations 8 . In this paper, we report for the first time in México data on the infection by Salmonella enterica and the seroprevalence of antibodies against Leptospira interrogans in D. virginiana. This information constitutes a contribution to the knowledge of the epidemiology of zoonotic diseases in México, where in spite the abundance of this mammal in peridomestic habitat, its role in the epidemiology of many zoonotic diseases has not been evaluated.The data of infection by S. enterica and L. interrogans in opossum, were obtained during a populational study of this mammal to evaluate its importance as a reservoir of Trypanosoma cruzi, the etiologic agent of Chagas disease 8 . Opossums were captured from April 1996 to May 1998 in Dzidzilché (21°08'51.76" and 89°41'28.24"), a semiurban small village located 25 km northwestern Mérida, the capital of the Yucatán State, México (Fig. 1). Thorny and low forest, and scarce remains of low deciduous forest characterized the vegetation of the study area. Many abandoned sisal fields doted the surroundings of the village. Fruit trees such as Mangifera inca (mango), Manilkara achras (gumtree), Spondias purpurea (plum), Citrus aurantium (orange), and Carica papaya (papaya), were common in the courtyards. The climate was predominantly warm and humid, with a mean annual temperature of 25.4 °C. During the study period, the rainy season ranged from June to October, and the average annual rainfall was 449 mm.The capture of opossums was carried out following the capture-markingrecapture scheme in a grid of 4 x 4 Tom...

“…All isolates were identified using standard techniques. 18 The bone marrow was considered to be hypocellular if the hematopoietic cells were 40% of the total cells, and hypercellular if the hematopoietic cells were 60% of the total cells seen on the bone marrow biopsy specimen. Dyserythropoietic, megakaryocytic and granulocytic dysplasia were defined according to standard criteria.…”

“…The bone marrow findings in this series of HIV patients appear to be similar to what has been previously reported from other countries. Ann Saudi Med 1996;16 (1): [16][17][18][19] [16][17][18][19] Few studies have addressed the issue of HIV infection prevalence and pattern of disease in Saudi Arabia.
