Volume 1, Issue 1 (4-2007)
Abstract

Abstract Background and Objective: Airborne fungi have been proposed as the most common cause of some adverse health effects such as skin, eye and respiratory disorders therefore, we carried out an aerobiological study to determine fungal seasonal frequency in the air of Zahedan, Iran. Materials and Methods: The air samples (n=1080) of this descriptive cross sectional study were obtained, in different hours, from different urban places of zahedan in 2001, and studied via sabouraud dextrose agar(S.D.A). Results: 1917 colonies were found in the 1080 studied plates and indicated that the most Common fungi were aspergillus(41%), penicillium(33%) and rhizopus(6.8%), based on chi square, The fungal frequencies in the evening(39.3%), at noon(38.2%) and in the morning(22.5%) were not statistically different . Highly contaminated area was down town (Bazar) and then hospitals. There was significant correlation (p<0.001) between fungal frequency and the seasons- winter (15.9%) and summer (31.4%). Conclusion: Based on the results, we suggest strongly improving environmental hygienic condition of the buildings and passages and rapid waste material disposal. It seems that the most effective strategy in decreasing fungal disorder is performing some educational programs. Keywords: Fungal agents, air, Zahedan.


Seroepidemiology of Toxoplasmosis among Pregnant Women Referring to the Reference Laboratory of Zahedan, Iran (2011)
A Ebrahimzadeh, S Mohammadi, T Davoodi, Ar Salimi Khorashad, A Jamshidi,
Volume 7, Issue 3 (10-2013)
Abstract
Abstract Background and Objective: Toxoplasmosis is one of the most prevalent parasitic infections worldwide. Contamination of pregnant women with toxoplasmosis may cause fetal death, preterm delivery and congenital toxoplasmosis. Due to importance of congenital Toxoplasmosis and the need of further study, this research was accomplished in Zahedan. Material and Methods: The serum samples (N= 221) were collected from pregnant women referring to reference laboratory of Zahedan in 2011. The IgG and IgM antibody levels against toxoplasmosis were investigated using ELISA method. Results: Out of all samples, 30.8% are IgG positive and 1.4% are both IgG and IgM positive. There is no significant difference between positive and negative groups using Chi-square tests. Conclusion: The main part of pregnant women in Zahedan (69.2%) is serologically negative against toxoplasmosis therefore, hygiene education to eliminate risk factors especially during pregnancy period seems to be imperative.

Volume 14, Issue 1 (1-2020)
Abstract
ABSTRACT
          Background and objectives: Nosocomial infections caused by antibiotic resistant bacteria is a life threatening health challenge. This study aimed to determine the frequency of antibiotic resistance genes in clinical isolates from hospitals of Zahedan, southeast of Iran.
           Methods: Overall, 818 isolates were collected from different hospital wards. The isolates were identified using conventional microbiological and biochemical tests. Antibiotic susceptibility pattern was assessed by agar disc diffusion method and determination of minimum inhibitory concentration of a number of antibiotics. Multiplex PCR was performed using specific primers for the detection of resistance genes.
           Results: The most common species were Staphylococcus aureus (25%), Klebsiella pneumoniae (22%) and Pseudomonas aeruginosa (14%). The rate of methicillin resistance among S. aureus, S. epidermidis and S. saprophyticus was 60%, 43% and 24%, respectively. In addition, 28.5% of enterococci isolates were vancomycin resistant. Among gram-negative bacteria, 45% of A. baumannii and 24% of P. aeruginosa were identified as ESBL. A high level of resistance to ampicillin (96%), cefotaxime (89%), gentamicin (89%) and sulfamethoxazole-trimethoprime (60%) was observed in K. pneumoniae.
           Conclusion: Our results highlight the urgent need for an eradication program and a surveillance plan for preventing increased emergence of antibiotic resistant bacteria in the study area.

Investigation of Cryptosporidium Oocyst Contamination in Water from Zabol and Zahedan: A Molecular and Microscopic Analysis

Volume 20, Issue 2 (6-2026)
Abstract
Abstract
Background: The presence of Cryptosporidium oocysts in water represents a significant public health concern due to its potential impact on human health. This study aims to detect and characterize Cryptosporidium in water samples from Zabol and Zahedan cities using microscopic examination and molecular methods.
Material and methods: 180 water samples were collected and analyzed at the Parasitology Laboratory of Zabol Medical School. Ziehl-Neelsen and Trichrome staining followed initial direct microscopic examinations, identifying contamination through the presence of Cryptosporidium oocysts at 100x magnification.
Results: Among these samples, 35 tested positive, 142 negative, and 3 were deemed suspicious. In Zahedan, the distribution was 9 positive, 2 suspicious, and 89 negative samples, while in Zabol, 26 were positive, 1 suspicious, and 53 negative.
PCR amplification targeted the ITS1 gene, and electrophoresis on a 1% agarose gel showed band patterns ranging from 871 to 961 base pairs. For genotype differentiation, restriction enzymes RsaI and AluI were used, with AluI generating distinct patterns featuring bands at 410, 457, 480, 760, and 850 bp. BLAST analysis revealed a 98.84% sequence identity with C. parvum. Phylogenetic analysis further indicated a genetic relationship with known C. parvum isolates.
Conclusion: This study provides comprehensive detection and molecular characterization of Cryptosporidium in the examined water samples. The results highlight the need for continuous monitoring and improvements in water treatment processes to mitigate associated public health risks.
